Individuals who are at risk of developing temperature related ailments, would benefit from consistent monitoring of their health metrics. This can be done through the use of a wearable upper arm band that continuously measures and monitors body core temperature, oxygen saturation levels and heart rate through the use of non-invasive sensors. Detection of abnormal physiological parameters, like low oxygen levels for example, will alert the user and a third party so necessary precautions can be made to prevent any health issues from worsening. ----------------------------------------------------- GasLight CO2 Sensitive Lighting James Bylicky, Tara Blittner, John Saputo, Michelle Nevins In a room with automatic light sensors, the lights will turn off after little or no movement. A proposed hybrid CO2 and motion sensor provides a method to both 1) Detect motion through a passive infrared sensor and 2) Detect CO2 concentration emitted from a human exhale in order to keep the lights on by determining human occupancy. The proposed design consists of three central components: a CO2 sensor, a central logic unit to record and process data, and an electrical relay capable of turning on and off a light. The goal is to keep the lights on effectively for a room size of 300 m^3. ----------------------------------------------------- Centripetal Force Water Filtration System Felicia James, Jerin George, Joy Abasolo, Mckingsley Williams Clean drinking water is not easily accessible in disaster affected areas. Lack of clean water will ultimately lead to various diseases and severe dehydration. The centripetal force water filtration system provides clean drinking water from contaminated water sources. The device consists of multiple filters, water passes through the filters using centrepetal force driven by a mechanical device powered through a rechargeable battery. ----------------------------------------------------- Garden Maintenance System Katarzyna Bramska, Ryan Gao, Lee Stetson, Zach Torpie The Garden Maintenance and Monitoring System idea will be designed to effectively combine soil pH, moisture, and light sensor probes via an arduino system as well as automatically water small plants such as beans, strawberries, etc. The system will measure soil runoff collected below the soil container. Once the water reaches a pH from water certain level in the collection unit, it will be pumped up into a reservoir container and reused to water the plant again. The automatic watering system as well as pH, soil moisture, and sunlight sensors will be controlled and monitored with an Arduino. ----------------------------------------------------- Cyclist Safety Device to Prevent Rear-End Collisions Chen (Kevin) Hao, Sebastian Puerto-Arenas, Sau (Jimmy) Lim, Jason Cheng When navigating complex roads or densely populated streets, cyclists are in danger of accidents with neighboring cars and other cyclists. Rear end collisions are the leading cause of cycling fatalities in the United States. Adding on lowered visibility situations, cyclists blind spots, the lack of bike lanes, and comparative size making cyclists difficult to see exacerbates the situation. A device that can sense oncoming traffic, predict rear end collisions and alert drivers of the cyclist's presence is necessary to prevent potentially fatal outcomes ----------------------------------------------------- 40-yard dash device Jingyue Zheng, Constantine Sargentini, Ilya Stotland, Barnabas Mako, Kelly Pabon "Short sprints are commonly used to determine the speed and acceleration of athletes. These tests, such as the 40-yard dash, are timed during solo training sessions. However, studies have shown that athletes obtain better results when racing a physical competitor, such as in a game. Therefore, in order to achieve optimal performance during training, that accurately represents an athlete's skills, a means of simulating a sense of competition is needed. The primary design goal is to create a mechanical pulley system which can be programmed to move a rope at a desired pace and attach a marker to the rope so that athletes can race against an imaginary opponent. By doing this, athletes will provisionally receive better results in training, and ultimately decrease their 40-yard dash times. ----------------------------------------------------- Smart Dispenser Justin Cohen, Alexandrea Innes, Matthew Mannetta, Macky Li Commercial buildings often have several bathroom stalls that may have insufficient amounts of toilet paper. The Smart Dispenser serves as a communication system that allows the custodial staff to get updated when the toilet paper supply is diminished. Using an optical sensor to distinguish the color of the toilet paper from the cardboard roll, the supply is always monitored. A GSM wireless communication device will be used to send a text message to the custodial staff once the optical sensor detects the color of the cardboard roll. A LED light will be used in the event that the notification system fails to increase reliability of the product. All electrical components will be encased within the dual toilet paper dispenser in order to reduce the exposure of wires in the environment. ----------------------------------------------------- Longboard Power Bank Aasif Jain, Dohee Kim, Hanjie Tan, Kenneth Luong The Longboard Power Bank is one of the solutions to extend battery life for USB devices. The design will convert mechanical energy produced from rinding the longboard into electrical energy. This can be done with the help of dynamos attched to the wheels of the longboard. The dynamo will generate electricity as it rotates with the wheels. The current generated from the dynamo will be stored in the power bank which will be used to charge USB devices. *********************************************************** *********************************************************** *********************************************************** Fall 2016 thru Spring 2017 "Automated Sealer for Trash Bags and Other Purposes" Taryn Black, Sergey Gelman, Olivia Higgins, Lauren Slater, Abdullah Yar An automated novel sealing mechanism for the medical industry that closes trash bags from inside the trash receptacle. The invention facilitates the disposal of waste, mitigates interaction with hazardous medical waste, and saves time spent on tying the trash bag. Both mechanical and electrical subsystems of the closing mechanism are controlled by an Arduino. Weight and infrared sensors are implemented to activate the sealing system for an accordingly timed seal based on the weight or intrinsic height of the waste. The determined full bag will be closed permanently with cable ties. ----------------------------------------------------- "D.A.B.: Drug Accountability Bracelet" Chukwuka Otuonye, Nitasha Roy, Teresa Martusciello, Mack McGuinness, Nicholas Olynik The Drug Accountability Bracelet (D.A.B.) is a wearable device focused on the detection of illicit drug usage. When a drug such as cocaine is used, it will metabolize in the liver. The unique metabolite, benzoylecgonine, is excreted through bodily fluids. Primarily urine is used to detect this metabolite, but benzoylecgonine also appears in sweat. This correlates to an individual's usage of cocaine. Typical detection processes require several days after individuals' use of cocaine. However, the D.A.B. will be able to quickly detect the metabolite either by an electrochemical reaction or based on acidity within 24 hours. Additionally, this device will include a heart rate sensor to determine if the individual is wearing the device. ----------------------------------------------------- Self-sorting Recycling Machine Jacqueline McGlynn, Joseph Giambalvo, Kharese Gittens, Oluomachukwu Agwai, Yeonjae Ji In recycling processes, proper separation of plastics, glass, and aluminum refuse is vital. Even in recycling outlets where separate bins and adequate labels for recyclable material is clearly displayed, wrong refuse are often dumped into the wrong bins. This design will tackle this issue by automatically sorting glass bottles, plastic bottles, and aluminum beverage cans and placing them into the proper recycling bin. The design will incorporate the use of photoelectric and inductive sensors to identify the composition of the recyclable and traffic the recyclable into its allotted bin via the use of motor-driven sliders. ----------------------------------------------------- "Automated Wiping System" Diming Lu, Jiawei Zhou, Oliver Lockwood, Richard Pak The automated wiping system is a device that is used to efficiently and quickly erase the markings on a whiteboard. This device has an adjustable top and bottom bar, which is attached to the top and bottom of the whiteboard, acting as the frame for the device. The frame gives the wheels that are attached to a vertical bar the direction to travel. The vertical bar is assembled piece by piece which allows user to freely adjust the width of the wiper. It also encases the motor, that powers the movements of the wheel. On the side which meets the surface of the whiteboard, is the dry eraser. This device will clean whiteboards faster, which will allow teacher to have more time and focus on teaching. ----------------------------------------------------- H2Woah - Water Consumption Monitoring Device Narmin Hasanat, Zachary Licht, Howard Siegfried, Andrew Sullivan, Antonio Xu Liu Despite efforts to reduce wasteful water use, showering is still one of the largest contributors to an individual=E2=80=99s water consumption. H2Woah aims to provide users with real-time feedback concerning their showering habits in an effort to drive down waste. The minimally invasive shower head attachment offers a quantifiable and relatable unit in the form of dollars spent per shower, with relation to the cost of water based on location. An easy-to-use LCD display will indicate features such as a live feed of the monetary cost of the shower, and temperature. Longterm showering trends can be tracked using a compatible mobile application. ----------------------------------------------------- "Steam n' Clean" Kevin Aguila, Sergio Daly, Daniel Melin, Colin O'Connor, Stanley Shaji In everyday life most people have to either steam or iron their clothes in order to look presentable for work or a social occasion. Currently many people live fast paced lifestyles that leave no time for these tasks. Within this age of technology there lies the means, with which, to automate past technologies. This design will steam clothes automatically, resulting in one less thing for people to worry about. The scope of this project encompasses a fully automated and programmable steamer with the addition of a UVC light for dissipating bacteria buildup. Our design will both steam and refresh clothing. ----------------------------------------------------- "Emergency Siren Detection System" Jorge Bonilla, Richard Chen, Aidan McNaughton, Alexander Schreiber The inability of a driver to perceive and/or locate the source of an emergency siren frequently results in collisions with emergency vehicles. A device capable of detecting and alerting a driver of the presence of an emergency vehicle will act to absolve this issue. The proposed design will distinguish and locate an emergency siren and inform the driver of these parameters by utilizing multiple frequency detecting sensors. The device's processing unit will be situated inside of the passenger vehicle, with the sensors being housed and mounted externally. ----------------------------------------------------- "Up-N-Atom Safety Walker" Richard Pilla, Sean Samaroo, Keemari Thompson, Matthew DeKoning Currently, wheeled safety walkers are very barebones, and consist of cheap parts, and in some cases present new dangers to the elderly and disabled. This design will improve on contemporary designs and incorporate additional safety features. Using infrared and ultrasonic sensors, the walker will detect obstacles and alert the user to prevent tripping. The alert will be based around a vibration system. Additionally, a locking wheel brake system will be connected to touch-activated handles and lock the brakes after the handles are released to prevent slipping while sitting or leaning on the walker. A switch will also be included to allow the user to either disable the obstacle alert system, wheel brake system, or both. ----------------------------------------------------- "The Sea-Bass" Rohan Sanyal, Tyler Yee, Naveed Ahmed, Lautaro Epstein, Sebastian Woznicki Access to electricity is important to everyday societal functions. Our project aims to create a device to generate and store electricity by utilizing turbines rotated by flowing water. The electricity produced would be stored in a lithium-ion battery and be accessible through an outlet housed within the body. The body will be secured using a line and will be semi-submerged in a source of flowing water. The majority of the chassis will be manufactured through 3D printing so as to reduce the rolling resistance that the turbines will endure, allowing for a higher rotations-per-minute (RPM) to produce more energy. The energy harnessed will provide ample power to operate various electronic devices. *********************************************************** *********************************************************** Fall 2015 thru Spring 2016 ------------------------------------------- "Phennix -Autonomous Early Wildfire-Seeking Drone" Edward Gildersleeve, Valliappan Lakshmanan, Martin Nunlee, Nicole Pasquino, Geoffery Rippy Presently, wildfires are most often detected by manned monitoring stations, aircraft flyovers, or members of public alerting authorities. This design will allow for the detection of wildfires in the early stages of formation without the need for constant human surveillance. Using GPS guided autonomous drones, equipped with emission sensors and infrared cameras, this design will survey a preprogrammed region and report back suspected wildfire locations. This sensor package can be retrofitted to any and all drone applications presently in use for the same monitoring methods. ------------------------------------- "DoorMann - Automated Car Door Collision Prevention System" Albert Marciniec, Michael Andreassi, Kevin Paray, Devon Bisson, Chiranshu Bhatia Opening a car door poses a risk of collision with unknown obstacles in the path of the door=E2=80=99s travel. This system will detect obstacles in the path of travel via ultrasonic sensors, and apply a sufficient force to the car door to bring it to a stop before collision occurs. The completed design will be both compact and robust, and be adaptable enough to fit onto any standard car door. ------------------------------------- "Solar Paneled Air Dispersal Extension (SPADE)" Michelle Duong, Ieisha Hinson, Linda Jin, Donald Liu, Ammarah Zaidi Having a car parked in the sun for long periods of time will cause the interior temperatures to rise and become uncomfortable upon e ntering the vehicle. Through usage of solar panels,fan units, and reflective windshields, it will be able to decrease the temperatures of the vehicle, while also limiting the amount of heat that will enter the vehicle. This extension will be ideal for use on hot days such as the Summer. ------------------------------------- "Bottle Muncher Can Jammer" Muyiwa Adeyeye, Andy Bertrand, Paula Brugnoni-Cobo, Yi-Hsin Chen, Jason Lai Plastic bottle and cans have large volumes that take up a lot of space. Therefore, to maximize the number of plastic beverage bottle and cans in one recycling bin, the Bottle Muncher Can Jammer will crush them with two cylindrical rollers with teeth that will pull the bottle through a narrow slit and crush them to one eighth of their original sizes. This way, the owners can recycle more bottles and cans as well as decreasing garbage bag usage and save money in the long run. ------------------------------------- "Vox Pump" Skyler Cange, Robert Harmon, Arvind Mangadu, Danny Nghieu, Nicole Vogel Most modern bicycle pumps are designed to be externally mounted onto the bicycle frame or the saddle rails, often left exposed where they can be subjected to debris, theft, and damage from impacts. The Vox Pump would reduce these instances from occurring. The Vox Pump is small enough to be mounted inside of a bicycle=E2=80=99s seatpost for safe = storage . It will have an alarm system that, when armed, will transmit an alert signal to the owner if the bicycle is moved excessively while the owner is away from the bicycle as a theft deterrent system. ------------------------------------- "Training Block Sensors" Yunlong Li, Natalia Popova,Thomas Quinto Practicing sprinting starts is a time consuming process. The training block sensor system builds on existing training blocks to help the coach collect runners starting reaction time from the first steps reaction, the second steps reaction, and the runner's velocity after the third step. The system's device will collect this data and place it in a table for a quick view, and can graph certain results together for a nice view of tens of data points. The system device allows for as many profiles to match the number of runners on a team, and for quick changing time between profiles using a touchscreen. Once the sensor system is set up a coach can leave the sprinters to practice on their own. ------------------------------------- "Good Vibrations - Audio to Haptic Feedback Device" Isabelle Cortes, Hannah Leonard, Brian Maddock, Nicole Moro, Madeleine Unger Hearing impaired people only recognize sound input though low frequency vibrations. Good Vibrations is a wearable product that recognizes a range of frequencies, which are put into three categories: low, medium, and high. Once the category is determined, the device will produce corresponding light and haptic feedback. This increases safety by alerting the user of danger by transforming audible alarms into vibrations and increases the quality of life by allowing a level of immersion into the surroundings that hearing impaired people may lack. ------------------------------------- "The Everyday Wheelchair" Thaylor Cacador, Kevin Chow, Tashi Sangpo, Brandon Shafran, Patrick Neville The proposed design is a wheelchair which gives the user a comfortable outdoor riding experience while maintaining the great indoor functionality of current wheelchairs. The lever operation will attempt to replicate a rowing motion to utilize a natural motion for extended use. The design will include a third rear wheel with two large front wheels positioned on the frame for optimal weight balance and comfort, a hand operated lever with adjustable height to allow for individual customization, and integrated suspension in the frame positioned by the third wheel. ------------------------------------- *********************************************************** *********************************************************** *********************************************************** Fall 2014 thru Spring 2015 -------------------------------------------------------------------- Peltier Camping Kit Fatimah Ashekun, Jessica Barnett, Vilyana Kalinkova, Richard Schmoll, Chatrik Sodhi If you get in a dangerous situation while camping and you are without access to outlets to charge your dead phone, what do you do? The Peltier Camping Kit utilizes the Seebeck Effect to produce electricity, without being connected to a major power source. All that's needed is a heat gradient, which will be produced by a grill and a cooler. The immediate thermal gradient between the two sides of the Peltier device will induce a voltage, which will then be transferred to a charging station that will store the energy as electricity. You can cook and keep drinks cold, all while charging your USB devices. -------------------------------------------------------------------- Timing Device for Pinsetting Motor Activation David Colucci, Andrea Gabriele, Jared Ferraro, Kyle Jaworowski, Larry Nembhard Older bowling alleys spend thousands of dollars a year on electrical costs to run the old fashioned motors that set the pins. These motors run continuously throughout the day once the lane is turned on. We aim to build a device that maximizes the efficiency of older pinsetting machinery. After a predetermined period of inactivity on the lane, the timing device will shut the motor off. The timing device will easily tap into the existing circuitry of the lanes and will be cost effective. Our project will allow bowling alleys to save money in electrical costs and energy, without the need for a complete and costly renovation. -------------------------------------------------------------------- Multipurpose Bike Lock Ali Islam, Naomasa Miki, David Wang, Yuwei Wang Bike owners typically pump their bike once a week. With our integrated bike pump and lock design, bikers will always have a pump with them wherever they go. The primary goal of our design is to provide a multipurpose lock to prevent theft, flat tires and accidents at night. The coil of the lock will be made from thick high-carbon stainless steel, making it much tougher to break. The pump is integrated into the lock head. Additional functions include a reflective coating for night-time riding. This design will provide safety, convenience and ease of use for all bikers. -------------------------------------------------------------------- Parkinson's Cup Ramey Baul, Anamul Haque, Steeve Lebrun, Kiranjit Singh Parkinson=E2=80=99s is a degenerative disorder that affects the central nervous system due to the death of dopamine creating cells. The most relevant symptom of this disorder includes mild to severe tremors. Extensive research to fight this disorder and figure out the cause of such disorder is still under way. We seek to create a versatile cup that interacts with the movement of those afflicted. The cup will counteract the tremors of the person to prevent spills. -------------------------------------------------------------------- Anaerobic Biogas Generation System for Residential Use Joseph Byun, Jessica Cruz, Alicia M. Elliott, Rachel Fenwick, and Tom Orvis Compostable materials composed over 50% of the U.S. municipal solid waste (MSW) stream in 2012, according to the Environmental Protection Agency. The combustion of methane generated from anaerobic decomposition of this material can serve as a renewable, carbon-neutral energy source, simultaneously decreasing unnecessary contribution to the MSW stream. Our biodigestion system will safely produce and capture methane-containing biogas from compostable waste for residential use. The system will serve as a controlled environment, with the opportunity to monitor moisture, pH, and temperature levels, thereby facilitating the anaerobic breakdown of the waste by methanobacteria more efficiently than is typically achieved in nature. The process will generate combustible biogas and soil-enriching fertilizer solids as byproducts. -------------------------------------------------------------------- Circultification Tower Brian Bedney, Gordon Burrows, Jimmy Lee, Adrian Otreba, Ling Rong Qiu As the costs of heating homes rises yearly, new innovations need to be created to save homeowners money on their heating bills. The Circultification Tower is a system that will save homeowners money on their monthly heating. Designed to combat the effect of thermal stratification, the tower will circulate the relatively much warmer air from the top of the room and mix it with the cooler air towards the ground level of the room. Equipped with two fans, the tower will be able to mix the air in the room consistently, which will increase or maintain the room temperature. This saves the homeowner money from having to increase or turn up the heat in a room. -------------------------------------------------------------------- Improved Stove with Particulate Reduction System Michael Brauner, TianHe Qu, Lacey Schwab, Justin Wong To be environmentally responsible, the burning of hydrocarbon fuels should not be entirely eliminated, but used more efficiently. Improved make burning hydrocarbon fuels much more efficient but the ultrafine particles that are emitted are more harmful to human health than the fine particulates emitted from traditional stoves. The goal of our project is to create a system that will reduce the amount of these harmful ultrafine particulated exiting from the exhaust. -------------------------------------------------------------------- Sustainable Supplement to Single-Use Coffee Pods (3SUCP) Olesya Bylim, Michael Penn, Alia Rafiq, Megan Salazar, Devin Sullivan Last year alone, more than 6 billion single-use-cups of coffee grounds were discarded in landfills. The excessive amount of time and effort needed to separate the coffee pod into its individual components stands in the way of sustainable disposal. Our team's proposal is to create a device that receives coffee pods and automatically separates, cleans, and prepares the single-use-cup for recycling. This multi-step process involves separation of the aluminum lid, plastic cup, paper filter, and coffee grounds into easily recyclable components. -------------------------------------------------------------------- Automated UV Towel Sanitation and Drying System Priya Dadd, Srujana Khanchibhotla, Fabiel Nunez, Kevin Thorp, Weishi Yan The continuous use of a damp towel over a period time creates the perfect environment for bacteria and fungus to grow (e.g., dermatophytes such as athlete=E2=80=99s foot and ringworms). Our solution is to create an easily portable and mountable towel disinfectant system. The system would be able to properly dry and sanitize towels (using UV-C technology) before every individual use. Our initial cost analysis is ~$200. This design ensures our model does not overheat and does not waste electricity. -------------------------------------------------------------------- Self-Watering Irrigation System Alison Egbon, Joseph De Molfetto, Samiha Shakil Conserving water is an important issue in society. Over the past decade droughts have been intensifying in the United States, and for much of 2014, 30% of the country has been in a moderate drought. Gardens require a large amount of water to maintain. The selfwatering irrigation system will provide an efficient way to water a small garden, requiring no contribution from a home water supply and very little maintenance. The device will use an air-to-water technique which will condense the humidity in the air to produce water. The water will reach the plants through a drip system. -------------------------------------------------------------------- CPR Training Mat Kilian Cardo, John Biore, Joseph Savelli, Andrew Zhang Cardiopulmonary resuscitation (CPR) is a technique when, executed properly, has the potential of saving a human life. However, cases exist where individuals practicing this technique were unable to deliver adequate compressions, and failed to properly stimulate the heart. With the introduction of the CPR training mat, one will be able to accurately monitor the depth and force of each compression, ensuring the technique is performed in a uniform and efficient manner. -------------------------------------------------------------------- *********************************************************** *********************************************************** *********************************************************** Fall 2013 thru Spring 2014 Sheri Bossong, Peter McChensey, Mier Muller, Kumar Persaud Solar Powered Wastewater Treatment Station Abstract: In developing countries, there is an inadequate method for treating wastewater leading to an increase in disease and illness due to unsanitary conditions.

This can be achieved on a household scale by recycling the cold water that is normally wasted when waiting for hot water when taking a shower. Currently existing hot water recirculating systems focus mainly on providing hot water instantaneously, which requires an inefficient, energy intensive process. To improve on this, the system will be made on-demand to limit energy inputs and focus on maximizing the amount of water saved. -------------------------------------------------------------------- Angela Horstman, Eric Agruso,Joseph Nowak, Michael Dolan, Oleg Shayko Mobile Bicycle Generator with a Solar Assist Throughout the world not only is there a need for electricity; there are many areas that lack an easily accessible source. By harnessing a natural source along with energy from transportation we will create easier access to a power source. The worldwide daily use of bicycles and the increasing demand for electronic devices creates the need for people to use both regularly. Our product will merge the two similarly to how the modern automobile has. -------------------------------------------------------------------- Gyeongmin Choi, Kai Suen Heavy Metal Testing Kit Designed for Soil and Food The industrial development is growing larger. Industries often discharge polluted water into lakes or rivers, mainly in China and India. The land nearby usually absorbs these water, and hence the land is contaminated by heavy metals. Yet, when these lands develop into farmland, the products grown are then contaminated as well. There are many testing kits for Pb in industrial products and there is a need for a new method to test for toxic contamination, not just for big farmland, but also for household. The idea is to develop a test kit that gives a simple field test for fruit, vegetable or even the soil whether they are contaminated or not. -------------------------------------------------------------------- Ram Pandya, Srujana Kanchibhotla, Mohammed Shahed Angular Knee Measure with Digital Display Physical rehabilitation is an integral part in enhancing and restoring functional ability to those that deal with physical impairments or disabilities. It is imperative that those undergoing this treatment have the ability to exercise properly at home to maximize results. Our goal is to create a multi-featured goniometer that is affordable to the general public, so that it can be used to ensure proper form during exercise and rehabilitation without the immediate guidance of a professional. -------------------------------------------------------------------- Dominic Silva, Steven Rosner Jawad Mourabet, Benn Yiufat Lam Carbon Monoxide Suppression Device Exposure to high levels of carbon monoxide (CO) is incredibly dangerous.

A safety system will automatically engage the wheels to the ground to prevent the rider from falling. -------------------------------------------------------------------- Kirill Nitikin, Filip Magda, Karl Rosello, Matthew Granata, Ian Sutherland Modular Pipe Diagnostic and Repair System Cracks in pipes are difficult to both detect and repair, potentially causing significant property damage. Our aim is to create a device which will be able to traverse a pipe in order to locate pipe cracks with a series of cameras. The device is intended to function mostly autonomously using a pneumatic movement system. After a crack is located, the device will attempt to fix the crack with an epoxy deployment apparatus. *********************************************************** *********************************************************** *********************************************************** Fall 2012 thru Spring 2013 Gerard Harley, Greg Smith, Binal Sheth, Devin Feeney Portable Water Filtration System Water contamination can cause widespread disease and death in areas of the world with poor access to potable water. People in areas without a supply of clean water either in remote locations, disaster zones, or undeveloped areas need an effective and efficient way to treat their water. Our goal is to create a low cost and portable water filtration system to be used by individuals or small groups when there exists a need to filter local water. Thomas Fann, Phil Bryan, Cathy Chan, Elaina Anderson "Methane Extraction System" Domestic water wells near hydraulic fracturing sites often have high levels of methane contamination. Methane is safe to consume, however in levels over 1%, the probability of asphyxiation and household explosions rapidly increases. This system is designed to sense the amount of methane in the water and subsequently remove the contaminant before the water exits the faucet. Collin Olson, Mike Inglima, James Ging, Agnes Hur "Low Cost Point-of-Use Water Filtration System" A low cost water filtration system is being designed for single families in impoverished areas. The filter will focus on removing particulate matter, volatile organic compounds (VOCs), and heavy metals; contaminants most commonly responsible for causing adverse health effects. Cloth, charcoal and chitosan filters will be used as filters, and solar panels will aid in extending the lifetime of the filters. Eric Chung, Amey Mohite, Alvin Chun, Crystal Yu "Pump-Filtration System by Multi-step Process" Recent advances in water filtration have created new and exciting prospects for drinkable water delivery system to many countries. Combination of easy accessible materials enables high quality filtering and optimization of multiple processes and techniques used in intricate water treatment system. Traditional water pump, specifically linear-type positive displacement pumps have potential to be improved in terms of its cost efficiency by instead, using reciprocating-type pump. In summary, the combination of the current techniques into highly compatible multistage system is producing increased efficiency in water delivery and filtration. Erik Perez, Edema Oviawe, Carlos Vasquez-Ortiz, Seemab Yousuf Emergency Water Desalination System Safe drinking water is extremely limited or non-existent after an emergency situation when people are stranded at sea or only have access to the ocean. In order to address this need, we are converting saltwater to portable drinking water. This process usually requires a large-scale desalination plant and plenty of dependable electrical power--neither of which is available in this type of situation. By using a compact reverses osmosis desalination system we will provide a portable solution that can be attached to a typical safety flotation devices or emergency kits and provide about a bottle of drinkable water. Luis Inamagua, Sergio Arauz, Timon Sewpal "Integrated Child Car Seat" The basis of our design is to integrate a child safety seat into an adult car seat. The seat will differ from conventional car seats by providing proper side and neck restraints while still employing the recommended five point safety harness system for a child under the age of 8. The use of power seat technology will enable the adult seat to convert into a child seat with the push of a button. Jenny Powell, Joseph Vierling, Josef Gaster Kinetically Powered Heated Gloves In any cold weather situation it becomes important to protect the body’s extremities from exposure and keep them comfortable. Traditional heated gloves rely solely on battery power or chemical heating, and are therefore limited to the life of the battery or to the chemical reaction. In an attempt to reduce battery waste and lengthen the use cycle of the heated gloves, a combination of a self-inductor coil and a magnet with a rechargeable battery circuit can be used. The inductance coil will harness the kinetic energy of the wearer and supply it as electrical energy to power the heating coils. Ryan Killian, Pallavi Kundu, Michael Miller "Improved Wireless Waterproof Headphones" Our senior design plan is to design a headphone/earphone set that is wireless, waterproof, and aesthetically pleasing. This headphone will be used primarily under low-pressure situations. The headphone will be designed to receive an FM radio signal to play music/sounds from sources including MP3 Players, laptops, and radio stations. The headphone will run on a rechargeable lithium-ion battery and will have an estimated life span of 2000 hours. *********************************************************** *********************************************************** *********************************************************** Fall 2011 thru Spring 2012 Giorgio Guidi, Carolina Jackob, Jill Geraghty, Steve Knox Automotive Cooling System Locking Radiator Cap A radiator cap is being designed that prevents removal when high temperature and pressure are present in he cooling system (radiator) of an automobile. Removal of said cap in these conditions can result in the rlease of hot pressurized steam which can cause harm to operators. Introduction of an elastomer in the design of the standard cap will create a locking mechanism that prevents the removal at high internal temperatures as a safety measure. The elastomer will be compressed by a washer when a nut is tightened on a bolt, exherting lateral pressure on the inside of the radiator filler neck. In addition, the locking elastomer will be designed with a method for safe removal by a knowledgeable operator or technician. Tim Ela, Andy Hsiao - "Indoor Environmental Analyzer" In a world seeking green energy solutions and cutting down costs, very rarely does both the environmentally friendly and cost efficient approach agree. Cutting down on heat loss in homes and buildings can save money and save the environment. The current methods and services for detecting heat loss in buildings, however, are much too costly for the average home owner to afford. By connecting low priced sensors to smartphone devices, the costs can be greatly reduced. The device will be composed of several environmental sensors including a temperature sensor, to measure temperature drops, a humidity sensor, to help regulate indoor humidity, and a dust sensor, to analyze indoor pollutant concentrations. These low priced components, combined with a user friendly interface via phone software, will create a product that can be used by a typical home owner. Kevin Nastos, Dan Israel, Alicia Azzara, John Yacobellis Electricity from Auto Exhaust Due to the fact that 62% of the energy from an internal combustion engine is lost through exhaust gases and fuel prices are increasing, it is becoming more important to conserve energy. Exhaust gasses are a wasted source of energy which can be harnessed through an alternative energy system. Our proposal is to use the free energy of a car's exhaust to rotate a turbine wheel which will generate energy through a magnetic induction system. This will optimally assist in charging the battery or a series of smaller batteries which can be used to power on-board systems. This will help to improve the efficiency and reduce emissions. Gordon Chin, Calvin Ng LifeBan A heart rate/blood pressure monitor band worn on the upper arm could record the raw data in the form of blood flow velocity and frequency of pulses onto a flashdrive. The raw data can be synced onto a computer at the user's request and be analyzed to obtain heart rate and blood pressure for diagnostic purposes. Another function of the device would be to alert nusers via their cellular device of their condition (silent heart attacks) and their contacts as well as emergency responders if a cardiovascular event were to occur. Kayleigh Reamy, Deanna Quickle, Matthew Ross, Tom Kirshenheiter Bump-It: A Portable, Energy-Generating Speed Bump for Construction Zones Numerous vehicular deaths and injuries in construction zones necessitate a system to increase driver awareness and control speed. This speed bump's design is portable for ease of transport and installation. The top crest also collapses under the weight of the car, transforming the potential energy into electricity which will be utilized to power warning lights, aiding to increase awareness without further straining the power grid. Ben Li, Qiyuan Wu, Panagiotis Orkopoulos, Radu Thomas, Zhihao Chen Oil Skimmer Project Oil spills such as the 2010 BP spill in the Gulf of Mexico underline the need to contain the disastrous leaks that accompany deep-water drilling. A new oil skimmer design, particularly of the drum and scrapper components, can improve the efficiency of this process. By optimizing the surface area, the skimmer can take a better advantage of the different viscosities of oil and its properties with respect to water, leading to a bigger oil quantity/time ratio versus that of existing skimmers.

Additionally, a light and panic button will be incorporated and easily accessible in state of distress promoting security and safety of the user. Jialiang Xian, Gordon Chen, Jack Yu, David Yao Cane/Reacher Our design is a cane with a built-in reacher that will eliminate the need for the user to bend down to pick up items. The reacher will be fully enclosed inside the cane and the cane handle will be coupled with a lever to initiate the push-and-pull mechanism for the reacher. The reacher will expand from the bottom half, allowing the user to retrieve hard to reach items. The handle design will implement ergonomics for maximum comfort. Umair Syed, Bradley Lesperance, Meng Li, Calvin Leung, Poornima Peiris Power Step: The Battery Charging Shoe The aim of this device is to transfer the energy produced by the walking/running movement to generate electricity, through the use of piezoceramics embedded in the heel of the shoe and protected by a gel-like substance. The impact/vibrations from running/walking will activate the piezoelectric material to generate electrical energy. In turn this energy would be used to charge handheld devices such as cell phones, iPods, GPS units, etc. Our design will encourage people to be healthy while they help make clean energy. Daniel Ross, Daniel Migiorino, Krista Jados Modular Piezoelectric Mats Our project consists of a regenerative power mat that generates electricity for charging either batteries or large capacitance capacitors that would then be put to use for other needs. The mat will generate electricity through the use of piezoelectric materials embedded in the mat. Piezoelectric materials generate electricity when compressed or otherwise strained. By placing the mat where there is high foot traffic, such as the entrance of a building it could be used to generate electricity, through having many people walk over it, straining the material embedded into the mat. The mat could also be placed in areas of high vibration to generate electricity through the same means *********************************************************** Fall 2010 thru Spring 2011 2010/11 Digital Stethoscope Amanda Chin Beach Shark "Net" Jack Davidson, Sean Cortes, Adel Djam StepNClean - Water Filtration Backpack Tom Schaefer, Christopher Hirschman, Riston Rocchio, Patrick Szeto GeeseBGone!

The second device is similar in principle but the suspending medium is solid silicone rubber. Braille Watch Mikael Marra, Angelica Tenazaca, Jennifer Jean Braille watches are of necessity touch-based, requiring that designs incorporate tough, touch-resistant materials.

However, such systems are typically subjected to dynamic loads during service. In addition, a number of industrial characterization tests involve dynamic loading, from commercial systems to hammer strikes. No systematic test exists as yet. The goal in this project is to build a well-controlled impact tester for thermal spray coatings on substrates, with the capability to operate at elevated temperatures. Apparatus to Laser Ablation Coat the Inner Diameter of Pipes Students: Mir Anwar, Kelvin Montero Technical Advisor: Prof. Henry J. White Abstract: The cost of petrochemical based products is governed by the price of materials of construction used in the processing of hydrocarbons. To extend the life of the construction materials, coatings must be used to bring down the coking problem faced by the industry. The solution lies in coating the construction materials with a coke-resistant film. Laser ablation is a technique that is used to deposit coatings of a variety of materials on a suitable substrate. On a laboratory scale it could be used to coat the material on small coupons but on an industrial scale, a little engineering is involved to devise a mechanism to coat inside cylindrical surfaces. Sometimes economics dictate the materials of construction to be used for a particular application. The use of more corrosion-resistant materials usually increases costs and tends not to be a viable option. A solution to this problem could be to use an inferior material and coat it to resist corrosion and extend life. On a laboratory scale this is usually done on coupons, but on an industrial scale it needs to be extended to coat both the inner and outer diameter of piping. Apparatus to wrap individual DNA molecules Students: Gary Bunch, Peter Gin Technical Advisor: Prof. Jon Sokolov Abstract: The biomedical industry has suffered over the course of time due to the inability to extract a length of DNA long enough in order to examine it in detail. The problem exists when just a few of the “code letters” are arranged in a manner unsuitable for healthy DNA, and that this arrangement must sometimes be viewed in a long strand of DNA to detect. Using conventional methods, only undesired lengths are obtainable, the longest presently equal to about 1 mm. The effect of having longer (up to 100 mm) strands of DNA would obviously yield a respectable leap and better data for use in disease control and understanding in the biomedical field. An apparatus capable of extruding a long single strand of DNA will be designed and built. Crystal growth furnace for Synchrotron UV-assisted chemical vapor deposition of wide-bandgap semiconductor nanostructures. Students: Jenee Gatkins, Vyonna Chweya Technical Advisor: Prof. Carlos Rojo Abstract: The synthesis of wide-bandgap semiconductor low-dimensional structures is fundamental to the fabrication of enhanced electronic and photonic devices. However, controlling the nucleation and growth of low-dimensional structures (nano-wires and nano-porous particles) remains as one of the major challenges associated with bottom-up nanofabrication strategies. A synthesis reactor for GaN nanostructures will be installed in the U11 beamline at the NSLS at Brookhaven National Lab. The ultimate goal of this project will be to determine the effect of UV photons on the selective deposition of wide-bandgap nanostructures. Development of a remote environmental chemistry laboratory for soil testing and monitoring.

This would be linked to a web page for development of remote education lab experiments for middle school through high school (and possibly college) students. The sensing system is in regards to the remediation and understanding of “brownfield” sites, which are sites that have low to moderate levels of industrial byproducts or residue in likely contaminated areas.

The device is intended to be used while being connected to a Keithley Multimeter to determine the material.s electrical properties. The device works by connecting to the metal strips with four contact points, with one set working as a source of current and the other measuring the potential drop along the strip. The commercial application of the device is in the electronics field for both labs and companies who wish to establish the reproducibility of their fabrication processes.

2004-2005 Project Description: Designing A Slurry Reactor System for Containment of Nanosized Metal Particles Point of Contact: Professor Devinder Mahajan Nanosized materials are considered the next frontier with potential applications in multiple disciplines. Nanosizing results in a larger surface area per unit volume that could result in enhanced reaction rates during an important class of reactions, namely catalyzed synthesis of clean fuels (fuels containing no sulfur or nitrogen). One of the reactions of commercial interest is the synthesis of clean hydrocarbons by catalyzed hydrogenation of carbon monoxide, also known as Fischer-Tropsch (F-T) synthesis. For commercial F-T synthesis, carbon monoxide and hydrogen reactants are typically obtained by steam reforming of natural gas and the reaction utilizes cobalt or iron-based materials as catalysts. The use of these nanosized materials is an attractive option to increase the space-time-yield of clean fuels but poses a challenge in the containment of these fine particles in the reactor. The project will assess various options to design a process that utilizes nanophase catalysts.
06/03/2004 Project Description: Develop a Sediment Washing Mixer Point of Contact: Prof. Clive R. Clayton Environmental remediation of lake, river and other sediments as well as soils by application of chelators and surfactants utilizes a mixing process. This project aims to simulate the industrial scale mixer for laboratory scale studies of the efficacy of cleaning solutions. The physical, mechanical and chemical components of the industrial mixing process must be analyzed and understood in order to build a portable bench top system.
05/26/2004 Posted project for Fall 2004 Project Description: Development of an Ultra-Low Load NanoMechanical Probe for BioMaterials and Small-Volume Structures Point of Contact: Prof. Andrew Gouldstone Indentation experiments are ideally suited for the investigation of mechanical and coupled behavior of small volume structures, as they require minimal specimen preparation and can be performed repeatably and quickly on a single specimen. Traditional hardness testers are typically found in many metallographic labs, yet the loads they apply range from many kg down to 10g. Instrumented indenters have been developed to apply loads to a lower limit of less than 0.01g, yet the complex depth-sensing abilities of these machines greatly increase the time of experiments (~20-30 minutes per indent), time of calibration, and the cost ($100-200k). In this study, we will aim to develop an inexpensive alternative to such machines. We will design and build a nano-hardness tester that is capable of applying a single dead weight load of (0.1 -1g) to press a hard (e.g. diamond or WC) indenter tip into a specimen, with a spatial (horizontal) resolution of ~1 micron. The quick, repeatable and simple application of such loads (and subsequent observation under optical and/or electron microscopy) will allow mechanical and functional probing of a number of different small volume samples, and the the mechanical variation in complex bio-materials, composites, coatings and thin film multilayers. The depth of mechanics and engineering involved in this project make it appropriate for a team of 2 people.
05/26/2004 Posted project for Fall 2004 Project Description: Design of a Jet-polisher for TEM specimen preparation Point of Contact: Prof. Perena Gouma This project involves the design and fabrication of a small polishing unit for thinning transmission electron microscopy specimens (of 3mm diameter) to electron transparency. The operating principle of such a polisher involves the simultaneous application of voltage and of a jet stream of an electrolyte (commonly a very corrosive chemical) onto the material to be thinned. The student/s to be working on this project will have to design and fabricate the electro-polishing cell, the jets, and the electronics controlling the voltage and the temperature (-30°C-50°C), current, and flow rate of the electrolyte. Extra points will be given for adding a timer and automatic shut-off control to this unit when a hole is made in the specimen.
05/18/2004 Posted project for Fall 2004 Project Description: Enviromental chamber for in-situ confocal and atomic force microscopy of living cells Point of Contact: Prof. Miriam Rafailovich Advances in tissue engineering rely on our ability to engineer new materials which allow for proper cell migration, proliferation, and differentitation. Nanotechnology allows us to design materials at the molecular level. Hence, we can in principal control the mechanical, chemical, and topographical properties on a nanometer scale. In order to fully exploit this abilitly, we must first understand the effects of each of these factors on cell dynamics. Cells respond to external stimuli in a complex manner that triggers a cascade of events resulting in integrin creation, construction of actin scaffolding, and gene expression. Since these processes normally occur over several days, it is important to have the ability to be able to culture cells directly under the microscope lens. Cell culture requires precise control over temperature, PH, and gas content, while maintaining overall sterility. I would like to challenge a student to come up with a desing for a mini cell incubator that fits into the confined enviroment of the confocal microsope or the atomic force microscope, while at the same time can maintain physiological conditions for prolonged times. Veeco Instruments, which is the parent company of Digital Instruments and Topometrix AFM is very interested in this project and their engineers will work closely with the student in interfacing the atomic force microscope with the cell stage.
05/18/2004 Posted project for Fall 2004 Project Description: Development of a high-pressure chamber for X-ray studies of III-nitride crystal growth from metallic solutions Point of contact: Gary Halada and J. Carlos Rojo Large GaN single crystals substrates are needed for the fabrication of novel III-nitride semiconductor devices for high- power, high temperature electronics, and short wave-length opto- electronics. While high pressure, flux growth is among the most promising approaches to growth GaN crystals, there is still a profound lack of understanding of the thermodynamics and growth kinetics associated with this growth technique. The optimization of this crystal growth process critically depends upon the understanding of the effect of the operational conditions (pressure of nitrogen, temperature, and chemical composition of the solution) and structure of the solution on the chemical composition and crystalline quality of the resulting crystal. This project involves design of a chamber to carry out characterization of the liquid-gas interface under conditions that can lead to the growth of III-nitride single crystals. Requirements: The chamber should be able to withstand high pressures (up to 100 bars). The chamber is equipped to heat the metallic solution up to temperatures between 800 and 1400 oC. The chamber must be compatible (in size and materials) with a typical beamline set-up at the National Synchrotron Light Source at Brookhaven National Laboratory (specifications on the exact facilities will be provided student will need to coordinate with beamline personnel on design.) The chamber must have a pathway appropriate for X-rays and must interface with standard X-ray detectors.

The students will learn about welding processes, material specifications, limiting factors controlling design of solidification substructure, and âhow to prepare metallographic specimens". At the conclusion of this project, it is expected that a poster will be produced that illustrates all five solidification substructures common to weldments: planar, cellular, cellular dendritic, columnar, and equiaxed.

Posted project for Fall 2004 Project Description: Powder Mixer Point of Contact: Jim Quinn This project will conceptualize, design, and fabricate a powder mixing system for SLS/RP (selective laser sintering/ rapid prototyping) powders. Students will select a powder mixing process. They will optimize the process for the types of powders used, such as polyamide, copper-filled polyamide, glass-filled polyamide, and stainless-steel. The fabricated mixer will be implemented to blend constituents as well as recycling of new and used powders. An important design issue will be the ability to minimize aerosolized powder during addition, mixing, and extraction of the powder. Another issue will be minimizing mixer contamination and cross contamination. Another issue will be easy of cleaning. Funding for components will available from the SLS/RP lab and lab-fee. The SLS/RP lab is a College facility, which is high profile with many visitors from industry, government, on-campus, alumni, WISE, STEP/CSTEP, and local K-12 schools.

We need to design a setup for samples having various sizes up to 3" diameter with thickness up to 200 mils. For samples with polymer coatings up to a micron, clean cuts must be made in the polymer as well as having the proper scribe marks for cleaving the silicon (using a diamond tip with adjustable tension). The design must include methods for conveniently mounting specimens while avoiding chemical contamination and the breaking must be done in such a way as not to have the polymer surface absorb debris from the break.

09/13/00 Fall 2000 Advisor: Prof. Gary Halada Topic: Sample Stage for Glancing Angle EXAFS This will involve design and development of a tilting sample stage with a stepper motor for use at the National Synchrotron Light Source at Brookhaven National Laboratory to create the capability to perform Extended X-Ray Absorption Fine Structure spectroscopy of this surface films. Initially, the stage will be designed to be compatible with port X10B but should be able to be used at similarly configured ports elsewhere. Design group is limited to two people. Students will need to make several visits to the beam line at BNL and work with personnel there to ensure a compatible design. Knowledge of CAD software required.
09/13/00 Design and Fabrication of an instrument for in-situ measurement during thermal spray processing. Thermal Spray Processing is a technique of applying thick coatings on substrates by a variety of methods - such as Plasma flame, Combustion flame, High Velocity flame, Low Pressure Plasma spraying etc. During the coating process, coating and substrate build up stresses due to the solidification of molten material and due to a difference in thermal expansion of the two dissimilar materials. Level of these stresses governs the functional response of coating-substrate system. Stresses in the coating and substrate can be estimated by measuring the response of substrate during the coating process. This project would include the design and fabrication of an instrument to measure and record the changes that a sample undergoes during the coating process. Measurements such as dimensional change and temperature history need to be measured and recorded. The instrument also needs to have a capability of measuring the coating thickness during spraying. Design considerations : * Ruggedness - since it will operate in a very hostile processing environment. * Portability - since the instrument will have to be used with different coating systems. * Possibility of designing this to be used in a vacuum chamber. Prof. Sampath: Room 105
09/15/00 Micro Langmuir Trough for Rheological Measurements of Ultra Thin films. Miriam Rafailovich and Jonathan Sokolov The mechanical response of ultra thin films can provide us with a fundamental understanding at the molecular level of the structure property relationships that play a role in viscosity, friction, and modulus. At the same time an understanding of these processes is important in the design of lubricants and coatings. The proposed project involves the design and construction of a miniature Langmuir trough with computer controlled barriers for pressure and area sensing. The trough should have the capability for an RF modulation to be applied to the barriers. The change in surface pressure could then be detected either by a Pt plate electrode coupled to a lock in amplifier or with an atomic force microscope. The first part of this project is the design of the trough and the second part involves interfacing the motors with existing amplifiers of the computer controlled electronics of the atomic force microscope.
09/13/00 Design and Fabrication of Special Fixtures and Data Acquisition system for Thermal Spray Processing. Thermal Spray Processing is a technique of applying thick coatings on substrates. These coatings are applied by a variety of methods - such as Plasma flame, Combustion flame, High Velocity flame, Low Pressure Plasma spraying etc. Depending on the purpose of spraying and the subsequent testing, substrates vary greatly in shape, size and material. During the spraying process, these substrates need to be held in fixtures - either stationary or rotating. While forming the coating on substrate, it is also important to measure and record temperature variations. This project involves the design and fabrication of fixtures that would accommodate a large number of standard samples simultaneously - for both stationary condition and rotating carousel. In addition to providing various methods of holding these substrates - such as magnetic holder, clamps, screws and vacuum chucks - the fixtures must provide for external cooling by cold air guns or closed circuit water. The fixtures must also have the capability of mounting thermocouples / pyrometers to monitor the temperature of substrate during coating. A temperature sensing / recording unit (such as a Data Acquisition System) will be part of the fixture. Design considerations : * Fixture designs need to dovetail with the existing equipment in the lab (mainly the spray booths and rotating carousels). * Material selection * Temperature data acquisition in case of a rotating fixture (either by using slip rings or by wireless transmission) and in the vacuum chamber.

Advisor: Prof. Richard J. Gambino 09/11/00 Design and Construction of an Electric Current Consolidation System for Powder Metal Processing It has been shown the metal powders can be rapidly consolidated into dense products by passing a large current through the powder compact. The system used for this process generally consists of conducting electrodes and an insulating tube containing the metal powder. The design problem requires material selection for the time/temperature conditions of the process. It has been calculated that the temperature of the compact rises to 900 C in about 0.3 seconds. A design with a replaceable tube liner is acceptable. The electrodes must be able to carry currents up to 200 amperes without heating to the point that they deform plastically or melt. Electrical insulation must be provided for the ends of the electrodes so that the apparatus can be put into a hydraulic press. The system will be used to make composites of magnetic metals with magnetic oxides for permanent magnet applications.
09/11/00 Design and construction of a miniaturized slurry drill for cutting small discs Advisor: P. I. Gouma This project will involve designing a simple device which will be used to cut mini discs (3mm in diameter) from metallic, ceramic, and composite materials. These mini discs are typically used for the examination of materials in the transmission electron microscope (TEM). The principle of operation of this device will be similar to that of the slurry drill equipment used in construction. The device should be easy to assemble and operate. Material selection for the main body of the device as well as for the drilling bits is a very important and critical process of the project. The hardness of the material from which discs will be cut willvary, depending on the material system used, and this is a design aspect to be carefully considered. Once a particular desing has been chosen, construction of the device is expected to be carried out. Ideally, the device will also include controls for its automatic shutt off once discs of appropriate thickness have been cut. (a two people team is required to work on this project)
09/07/00 Posted project for Fall 2000 Industrial Application for an Instrumented Standard Hardenability Device Faculty Advisor: Dr. Henry J. White Hardenability is a measure of the depth to which steel will harden when quenched from its austenitizing temperature (Ac3 = 910 - 203 (C «) - 15.2 (Ni) + 44.7 (Si) + 104 (V) + 31.5 (Mo) + 13.1 (W)). The proposed design project involves the construction of an instrumented end quench device which will determine the cooling rates that lead to a particular level of hardening for a given steel. The challenge will be instrumenting the apparatus to accurately monitor temperature and time during the heating and cooling cycles. It is recommended that (1) current standards (ASTM A914, ASTM A304, and ASTM A255) be used as the basis for design and (2) that hardenability and cooling characteristics of different steels be measured utilizing existing theory. The resulting data will be used to select the proper welding conditions (i.e. voltage, current, travel speed, preheat temperature, etc.) required for each steel to avoid the formation of susceptible microstructures.

Motivation: Atomic force and friction force microscopy is very sensitive to the conditions on the first few moecular layers of a surface. Consequelty adsorbed water, simply due to ambient humidity can significantly affect reuslts. Furthermore, in order to obtain the moleuclar scanning resolution it is esential that air transients be minimized
Project: Construct a plexiglass enclosure to mount on the air table of our Dimesnion 3000AFM where dry gas can be circulated and the humidity measured and controlled. Design temperature and humidity sensors that can be interfaced with a computer feedback control system.

Scanning Hall Effect Microscope
Advisor: Prof. Gambino
Since the invention of the Scanning Tunneling Microscope (STM) and the Atomic Force Microscope (AFM) many other scanned tip microscopes have been demonstrated. The objective of this project is to design and build a mechanism for scanning a small metal tip (like a needle point) over a flat surface. The surface might be a thin metal film deposited on a glass microscopy slide or the polished surface of a semiconductor crystal. The xy motion, the area which can be scanned, must be at least 0.1 mm by 0.1 mm with a resolution of at least +/-100 nm. The tip will be used in contact with the surface but a mechanism will be needed for lifting the tip off the surface when the xy scanner is in motion.
The microscope will be used to create an image or a map of the distribution of Hall voltages on the surface of the sample. In a semiconductor the sign and magnitude of the Hall voltage depends on the distribution of impurities (p and n regions). In a ferromagnetic metal the Hall voltage depends on the arrangement of magnetic domains. During operation it will be necessary to apply a magnetic field to the sample and to pass a current through the sample. Therefore, the magnetic and electrical properties of the materials used in the construction of the mechanism will have to be considered in the design.

Topic: Digital control of X-ray diffractometer
Design and implementation of software and hardware to control a Philips X-ray diffractometer. There are several possible avenues of approach. The chosen approach must consider the detection and discrimination of the raw signal; the motion of the theta drive; the shutters, limits, and interlocks; the plotting/outputting of spectra; and appropriate control via parameterization.
Design and fabricate a system of parts compatible with a vacuum environment by which a substrate can be held in place and two different masks can be brought in contact with the substrate surface at given times. The masks must be compatible with one another, i.e., they must be properly positioned and aligned so that the patterns produced by the two masks have the desired relative orientation and shape.
It is necessary to take into account the fact that the substrate may have to be protected by suitable shutters before and after the use of the masks.
The system should be designed, built and tested.

Temperature controlled sample holder for neutron reflection experiments:
Aim: design a temperature controled vacuum chamber which mounts on a beamline at the NIST or BNL neutron reactors. The chamber must mount on a goniometer, have windows to allow entry/exit of the neutron beam, and have an computer controlled temperature sensor. The chamber must also be designed to hold at least 10E-08 Torr vacuum, to prevent polymer degradation. This chamber will be used to study in beam polymer dynamics, phase transitions, and crystalline ordering.

Title: Uniaxial Traversing Stage For Thermal Cycling Rig
Personnel required: Two
Skills necessary: Windows-based data acquisition and control programming.
Advisor: A. Newman, Hvy Eng. Rm. 009, email@example.com
The Thermal Spray Laboratory produces coatings by injecting powders into various types of plasmas and flames. A type of coating that is very successful in the aerospace industry is the thermal barrier coating (TBC), used currently on jet engine blades. This coating permits the exterior of the blade to reach temperatures several hundred degrees above the melting point of the substrate metal. The primary cause of TBC failure is thermal fatigue. Hence, an accelerated test is required for examining potential next generation coatings. The requirements for the thermal cycling rig are: 1) to traverse the samples from a cold zone to a hot zone, 2) to monitor the coatings temperature, and 3) to record a picture of the coating after each cycle. A single computer to control the data acquisition, CNC controller, and framegrabber would be favorable. Our laboratory has a tube furnace, traverse slide, controller, and computer available for this task. Other components necessary to complete the design project will be purchased, with the assistance of TSL, after approval of the design concept.
Design and Implimentation of an Environmental Chamber for Sliding Wear Tests
The objective of this project will be to design a chamber around an existing wear test machine in order to be able to conduct tests at high temperature (up to 500C) and under vacuum or inert gas atmospheres. Hence, the chamber must be able to withstand high temperatures, vacuum and high pressures. The chamber will be transparent in order to monitor the surface during testing. Furthermore, it will be required to monitor the tempearture of the test specimen.

Design and Construction of a Dry Sand Rubber Wheel Abrasion Test Set-Up
The objective of this project will be to design and fabricate an abrasion test set-up according to ASTM Standard Test Method. The project involves collecting information on the requirements of a set-up, collecting raw materials and other components, designing the set-up and implementation of the design strategy.

Title: Design of a Hot Air Polymer Spray Gun
POC: Prof. Herbert Herman, 632-8510
Polymer spraying represents an emerging sector of thermal spray technology. This project entails the design and implementation of a device capable of heating and accelerating air and injecting polymer powder into the heated air stream. Such a gun design would allow polymeric coatings and composites to be deposited without using a traditional combustion process.
It is envisioned that a serpentine heater will be used to heat inert gas or compressed air. The gun nozzle must be designed to produce high gas velocities. The inlet gas pressure, volumetric flow rates, power, and powder injection rate must be optimized or "tuneable" to melt polymer powders with a range of melting points. The proper powder injection angle is critical to deposit coatings with high deposition efficiencies with corresponding high densities. This project requires knowledge of thermal transport, polymer science, fluid mechanics, and component integration.
