Remote Perimeter Access via Wireless Fingerprint Identification System

By Matt Plautz, Adam Schulz, Brandon Smith

Security of one's personal belongings and sensitive information is an important issue for most people. The current state of the world demands higher and higher levels of security. Passwords are commonplace for computers, locks, even cell phones. Encrypted signals are used for government transmissions and corporate information sharing. This project will implement a handheld device that incorporates fingerprint recognition used to gain access to a door on a house or office facility.

Anemometer (Wind Speed and Direction Detector)

By Abdou Balde, Pinkle Patel, Bruce Svare

The invention is a sensor pod for mounting on the surface of the fuselage of an aircraft. This sensor pod will accurately measure the humidity, pressure, temperature, and wind velocity. This invention will describe the development of a small, robust, and reliable ultrasonic wind speed and direction indicator, known as an anemometer. The ultrasonic technology is based on time–of–flight operating principle, which provides vector measurement of air velocity, given the dimensions and geometry of the pairs of sensors. Three pairs of sensors are used such that air velocity can be derived along orthogonal axis, and hence the air speed and direction can be computed. The method of measuring is based on the inverse transit time difference measurement of ultrasonic pulses on an upstream or downstream of the airflow.

Water Clarity Measurement System

By Amber Ahmann, Beth Donnay, Dan Reichert

The current method for measuring water clarity is with a Secchi disk that introduces many variables and error to the clarity measurement; our system eliminates these errors and allows for better tracking of data.  Water clarity is measured by a submersible module containing modulated LED signals received by photodiodes at a reference distance and a further discrete distance.  The transmittance over the fixed distance of water is calculated to counterpart the current Secchi disk method.  The module that remains on the boat displays the current location, depth, water temperature, and calculated Secchi measurement found by the module underwater.  The data collected is also written to a flash drive which can be transported to the data analysis station on land.  The analysis station is a software module containing a processing script, database, and correlations of calculated Secchi measurements to location, temperature, and depth with appropriate graphs and tables.

Internet Interface for Embedded System

By Khem Chapagain, Anjan Pradhan, Jeff Gill

There are two parts into this project.  First, this project uses TCP/IP embedded in a small hardware device to send wait time information of a restaurant to a website, so that people could access this information and be able to see the wait time at many different restaurants all at one time.  The second half of project allows a remote user to access a device placed in a business or home, which is connected to common household appliances.  In this specific design, the remote user would use a website to interact with a digital thermostat, electric door lock, alarm system, and light in a home via the internet.  The device in the home also provides feedback to the website including the temperature of the room and if the light is on or off.  An alarm system is also included on the device that will trigger if the temperature in the room exceeds certain specified values or if the device has some sort of malfunction.  If this happens an alarm will sound and the device will send an e-mail message to the user.

Wirelss Fingerpring Access Control

By  Matthew Plautz, Adam Schulz, Brandon Smith

The need to identify oneself in today’s world of high security is a concern for business and private citizens.  Passwords and passkeys are common place and utilize what you have (key) or what you know (password) strategy.  In very high security access control “who” you are is becoming more commonplace.  One of the best ways to determine exactly who someone is, in the scientific sense, is to use biological traits such as DNA, retinal patterns, or fingerprints.  The project attempts to bring a fingerprint recognition system together with wireless remote technology to improve security and implement a level of convenience for the user.

Autonomous Lawn Mowing System

By:  Patrick Baumann and Holly Dombrovski

Lawn maintenance is often a time-consuming and physically demanding task that homeowners must either handle themselves or pay a fee to have handled by laborers.  This research is targeted at developing a system to remove the requirement of physical work and observation by the homeowner in the mowing aspect of lawn maintenance.  Options for creating such a system were analyzed based on cost, efficiency, usability and safety among many criteria.  It was determined that an electrically powered system would provide the best balance to meet our criteria.  Further requirements include developing a charging system that uses solar power as its primary energy source as requested by Force 10 Networks.  Upon completion, this project should produce a prototype lawn care system platform capable of autonomous movement and self-charging.

Autonomous Meteorological Aircraft

By  Ryan Doheny, Nick Stein, Eric Voegele

This project’s purpose is to explore the concept and feasibility of autonomous flight with a small-scale platform.  The autonomous aircraft is to be used to carry weather measuring devices.  This will be a significant improvement over current weather measuring techniques.  Our craft will give mobility to the devices used in making measurements of air temperature, air pressure, relative humidity, and wind velocity.  A “quad-copter” platform was the chosen design for the autonomous aircraft.  This design consists of an aluminum frame made up of electric motor.  The scope of the project includes the construction of the aircraft along with the implementation of the necessary electrical components. 

Powertrain for an Electric Motorcycle

By  Zach Tatge, Damir Krehic, Motohisa Suzuki

This project addresses the issue of finding alternative modes of transportation other than burning fossil fuels.  Electricity is readily available and it can be used to power other forms of transportation.  An electric powertrain provides an efficient, clean, and cheap mode of transportation.  This paper addresses designing an electric powertrain for alternative transportation on an urban commute with a motorcycle.

Control Interface Conversion for an Electric Motorcycle

By  John Steckelberg, Jesse Toomey, Sutee Sappurissakul

The goal of this project is to design and build lighting braking, sensor, and display systems for an electric motorcycle capable of carrying one person.  The complete system will include batteries to supply power to the lights, sensors, brakes, and display along with a charging system for the batteries.  The system will be able to operate continually for a minimum 4 hours without recharging.  The lighting system will consist of headlights, brake lights, and turning signal lights.  Each of these would be implemented using ultra bright LEDs.  The braking system will be realized by adapting the current mechanical system to work with an electric motor.  The sensor system will include sensors to monitor the speed of the bike, the charge of the battery for the main motor, charge of the battery for the lighting system.  The batteries must have sufficient capacity to supply power to all the systems.  The charging system will bring the batteries to full charge within 8 hours of continuous charging.  This project will use electrical knowledge to help address the problems of fuel consumption and further the pursuit of environmentally friendly transportation.

Automation of Liquid Chromatography Instrument

By  Sunny Ahmed, Deepak Rana, Taqi Raza Nasir

The purpose of this project is to design a controller for Water 501 HPLC Pump, used by the Chemistry/Biology department for Liquid Chromatography and to develop a system that can be interfaced with a computer to collect analog output from a detector and perform various calculations by digitalizing and analyzing it and then display the results on a GUI system.  The device should be accurate, reliable and user friendly and it should be capable of delivering exact proportion of liquids as desired in the millimeters/minute range and also collect data such that it could be easier to understand and worked upon when displayed.  This will allow students and faculty of Biology and Chemistry department to perform liquid chromatography experiments from the luxury of their work station.
