Our team is one of two groups working on TA John Capozzo's impact logging project idea. Group members: Evan Qi Matthew Schafer Matthew Hebard Impacts are a substantial problem within the realm of high impact sports. Our project involves a system that detects, processes, and stores data from accelerometers and heart rate monitors. Because not all high impact athletes wear helmets that the system could be implemented in, our goal is to make the device small enough to be worn anywhere on the body (preferably on the neck). These are the high level requirements for our project: 1.) Collection of heart rate data 2.) Calculation of linear acceleration of a registered impact 3.) Items 1 and 2 time locked 4.) Time locked data stored in some type of non-volatile or easily removed memory for long term storage 5.) Aesthetically pleasing design and size that does not interfere with user activity and also promotes use of the sensor(s) during game time (wearable should be as small as possible) 6.) Robust to high impacts in terms of sensitivity and function with a determined usable life Sensors: The array of accelerometers will be designed in such a manner that an individual should be able to wear it. A separate sensor for the heart rate will be included as well. The data stream will be fed into an A/D converter at a preset sample rate. Then, this digital data will be fed into a microcontroller unit to filter out noise and time lock the data from the separate sources. Data Storage Unit: We want something small to store the data from the array of accelerometers, so right now we are leaning towards a microSD. The microSD also gives an advantage of being flash memory, so power will not be required to retain data. The storage device must be able to survive high force impacts, so it must be tightly fixed in position. Power: The system will draw power from a rechargeable battery. The device only needs to last for the duration of a game or practice, so a lifespan of only a few hours will be necessary. A typical AA battery can last a few hours with an estimated power consumption of a couple watts. |
