Project Description
Team IMPACT has decided to design and prototype an intelligent helmet that wirelessly transmits real time sensor data for collection and processing. The design of the helmet will allow it to be retrofitted into any type of protective headgear. This helmet will be used to monitor the wearer's motion, impact, and physiological states and indicates if any medical attention is necessary. Sensing is accomplished by using accelerometers to measure impact and motion on all three axes. Depending on the application, optional components can be added to fit its needs such as sensors that measure blood oxygen level and pulse. The collected data will be locally processed and wirelessly transmitted to the base station. The base station will interface with a computer that serves as the display module supporting a custom user interface.

Project Description
Our basic idea is to creat an In-Car Automation and Monitoring System. Sensors will be placed througout a car with each sensor sending data wirelessly gack to a central terminal using Zigbee Wireless technology. Recorded data from all system sensors will be displayed on a central Liquid Crystal Display (LCD) with user interface capability. Visual and audible warnings will be given if sensors detect individual readings that are beyond configured tolerances. Primary focus will be given to monitoring, reporting, and alarming on each car tire pressure. Secondary priorities include Temperature, Accelerometer, Proximity Sensor, and car battery voltage. A stretch goal for the project is to store and relay accumulated sensor data to a remote location in real-time via a wireless link.

Project Description
Our goal is to design a device that can be used to keep a ferromagnetic object held in mid air. It will use several electromagnets and optical/ultrasonic sensors along with a closed loop control system to achieve this goal. Initially, the device will hold an object in a stationary position, but eventually it should be able to control the object's position in three dimensions (pitch, roll, and yaw). The magnets will be controlled with DC-DC converters that will allow control of the voltage from 0-32V ideally. Each electromagnet will have a distance sensor in alignment so that the distance from each magnet can be controlled.
Theory of Operation: A ferromagnetic object can be attracted by a magnet. By using electrically controlled magnets connected to a series of sensors, it should be possible to control the position and motion of the object.
Physical Characteristics: The device will be a square box with open sides and top. Magnets and sensors will be mounted on the top and vertices of the box. The mass of the object to be lifted will be determined by experimentation.
Limitations: Power limitations could restrict the mass of the object being levitated. Only a ferromagnetic object will be levitated at this point. Due to sensor and controller limitation, it may be necessary for the object to be symmetrical.

Project Description
This RFID reader will be able to read multiple RFID tags and look up information relating to these tags from a database stored on an SD card. If the information is not found in memory, the reader will attempt to download the information from a central database via WIFI connection. The information will be displayed in a user-friendly format on a touch screen LCD display. Audio information tied to the tag will be output though a standard stereo jack on the reader that can be used with headphones. There will be an option to select which tag's information to display out of all those in proximity to the reader. Ideally, signal triangulation could be used to sense the direction and distance to the detected tags. Function List:
- Sense and read all RFID tags in vicinity
- Retrieve information tied to sensed IDs from database
- Database stored on SD card or downloaded through WIFI connection
- User-friendly graphical interface, maybe touch screen controlled?
- Able to read both passive and active RFID tags
- Able to read information from sensor type RFID tags
- Ability to evaluate approximate distance from tags from signal strength or triangulation.
- Standards compliant device, works with off the shelf standardized RFID tags.
- Battery Operated

Project Description
Solar energy is one of the leading renewable energy sources. Its use is predominant in power generators, heating, air conditioning, as well as industrial processes, water distillation and several other applications. However, a large problem with solar panels is that they may not receive the maximum amount of light possible. This is because of the sun's movement relative to the earth, which limits the total amount of incident light normal to the panel itself. The purpose of this project is to design and develop a low-cost solar tracker that will be able to detect the angle where the highest intensity beams are present and shift the position of the panel to that angle. Currently, solar tracking devices cost several thousands of dollars, and are not very efficient. This team will build a system under $1000, running a more cost-effective algorithm. The device is intended to be developed by this team during the Spring semester of 2008.

Project Description
The objective of our project is to create a robot that detects a cell phone signal and then moves toward the strongest signal. When the robot gets to the source of the signal it would then notify the user that cell phones aren't allowed in this area. There are a lot of control aspects to this system. Below is a list of the things we hope to accomplish throughout the semester.
- Movement of the robot
- Robot roams autonomously to find the strongest cellular signal.
- Robot responds to set reference signals,i.e. home".
- Object avoidance.
- Servo motors configured so that the robot can turn on a dime.
- Memory of path travelled.
- Detection of the signal
- Detection of cell phone signal.
- Detection of our own transmission, from say the "home".
- Controlling the system wirelessly.
- Modes of the robot
- Detect any signal to tell the user to turn off their cell phone completely.
- Detection of cell phone use and notification that cell phones aren't permitted in the area. "
- Home"
- A place to recharge the robot.
- (?) Using solar power (from power lab)
- A frequency beacon to tell the robot where to return to.
- The robot itself
- A power meter (battery charge detection).
- Screen for displaying messages.
- Lights and sounds.
