| abstract |
The physical activity data collection unit includes one or more infrared sensors configured to provide an output indicative of a user's pulse rate and at least one temperature sensor configured to provide an output indicative of at least a user's body temperature And at least one accelerometer configured to provide an output indicative of user activity. The physical activity data collection unit determines a user's pulse rate, body temperature, and operation characteristics based on outputs of the infrared sensor, the temperature sensor, and the accelerometer, and determines the user's pulse rate, body temperature, and operation characteristics. Configured to determine a user's physical activity level based on one or more and store in a memory data indicative of the physical activity level during a period when the physical activity level exceeds a predetermined threshold; Includes a microcontroller. |
