Emergency Response Rescue, Locator System

By: Jacob Bjorke, Kudakwashe Deve, Urbain Nde

Description: Finding disaster victims can be physically challenging for the rescue teams. These disasters occur naturally at home, places of work, and recreational facilities. Knowing the status of the victim buried under rubble, ice, or just wandered off into the woods can be very helpful to response teams. They can redirect their resources accordingly to either rescue or recover and call for adequate manpower. It’s even better when emergency teams can be able to tell the location of the victims(s) without necessarily being able to see victim(s). This project seeks to reduce the reaction time of those responders by developing an electric locations system capable of bringing forward information crucial to decision making at a disaster scene.

Multi-Touch Screen and Telepresence Robot

By:  Suraj Poudel, Joseph Meyer

Description:  The interaction of human to a computer can be made easier and simple with different ways besides using a keyboard and a mouse. The capability of using own fingers to interact with a surface so that the use of a keyboard and a mouse can be eliminated led us to build a multi-touch surface for the Senior Design project. The surface was built using the idea of Frustrated Total Internal Reflection which involves shining the infrared lights through the edges of the surface to be used and frustrating the lights by touching the surface to a camera that acts as an input to a PC. The inputs are then simulated using open source software and treated as mouse clicks for the PC. The image of the PC is projected back to the screen where the user can interact.  A tele-presence robot which was also built to send an audio and video feed to the multi-touch surface via web through which the user can control the robot for directions and speed.

Warehouse Inventory Control System

By: Adam Betzold, Cody Blair, Nick Wirtz

Description: For Fall 2009 and Spring 2010 semesters, a senior design team worked on creating a Warehouse Inventory Control System. This system is composed of a database that stores different product information such as a product’s name, number, and quantities. The mobile device gains uniqueness by providing a user with the ability to read both a Universal Product Code (UPC) and a Radio Frequency Identification (RFID) tag. The mobile device for the Warehouse Inventory Control System includes a LCD, keypad, PIC chip, transceiver, battery, barcode scanner, and RFID reader. With the end of the Spring 2010 semester coming to a close, the Warehouse Inventory Control System was a success. The system was able to obtain product numbers via three input methods which were the RFID reader, barcode scanner, and a traditional keypad. The system was also capable of being used wirelessly to obtain product information, create product lists, and edit product quantities within the database.

Electronic Devices for Ultrasound Vibrometry

By:  Bijendra Aryal, Adip Karki, and Ravi Shrestha

Description:  The main objective of this project is to design devices to replace the commercial products for the existing ultrasound vibrometry system, which is a medical system that can be used to estimate the properties of tissues like viscosity and elasticity. These properties of tissues can be used by doctors to diagnose the diseases in the tissue. The ultrasound vibrometry system is an integration of various devices, most of it will be designed by us, and some of the commercial components will be used. The main goal would be to design the devices according to the specifications given to us and           integrate them to a single unit. The system will be able to vibrate the tissue and detect the vibration in the tissue. The detected vibration signals will be processed   to obtain the properties of tissue such as elasticity and viscosity.

The Precise Semiconductor Measurement System

By: Andrew Vall, Huey Lee, and Martin Weygand

Description:  The goal of this project is to develop a test system for solid state device voltage current relationships, which he/she can use to gain better        understanding of the device.  This project consists of a way to measure currents with pico-ampere precision, a way of controlling the measurement procedure, and a way of getting these results into the computer. Some of the objectives of this project are as follows. The system must be extendable to future semiconductor research, meaning it must be modular. If a new method of current measurement is devised, future researchers should have a means of implementing it with the present system. 

Myoelectric Prosthesis

By: Christopher Neilson, Muhammad Usman Mirza, Garrett DeZeeuw

Description: The goal of the electromyographic (EMG) prosthesis is to model the movement and behavior of a human arm and hand in a simplified manner. The prosthesis moves in three independent degrees of motion: rotation about the elbow, rotation about the wrist (pronation/supination) and rotation about the hand (gripping).  The prosthesis is controlled entirely by electromyographic signals. These are the electrical impulses generated when muscle fibers are activated. By using disposable surface-mount electrodes, signals from below the skin can be detected and amplified. These signals are then used to govern the movements of the mechanical prostheseis.  The main source of converting electrical energy to mechanical energy within this project is nitinol. Nitinol is a material that is and alloy 50%  nickel and 50% titanium which undergoes crystal changes due to temperature induced phase chase change. Electrical energy heats the nitinol, which contracts up to 5% due to the phase change. This phase-change induced contraction is then amplified via mechanical advantage of the necessary magnitude in the prosthesis.

Formula-Hybrid Competition Electrical Engineering Design

By: Brent Swanson

Description: Hybrid vehicles including buses, cars, trains and SUVs have become and important part of modern society. With the recent concerns of global warming, hybrid vehicles have gained popularity not only in the technological industry but also the general public. Government support is also being extended to all constituents of hybrid vehicles from the manufacturers to the consumer. For these reasons we foresee hybrid vehicles becoming far more important in the future than they are today. This report will explain the drive-train system used in our hybrid vehicle along with the on-board charging and control systems.
