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:
