Abstract: A physical activity data collection system includes one or more accelerometer units in communication with a data collection unit, where the data collection unit, includes one or more infrared sensors configured to provide an output indicative of a pulse rate of a user of the physical activity data collection unit. The data collection unit may also include at least one temperature sensor configured to provide an output indicative of at least a body temperature of the user; and at least one accelerometer configured to provide an output indicative of movements of the user. The system may also include a microcontroller configured to evaluate the outputs of the two or more infrared sensors at a plurality of power levels; select at least one of the two or more infrared sensors for data collection; and reduce an amount of power applied to infrared sensors other than the at least one of the two or more infrared sensors selected for data collection.

Abstract: A physical activity data collection system may include one or more accelerometers configured to provide an output indicative of movements of an individual. The system may also include a controller configured to analyze information relating to the movements of the individual, based on the output of the one or more accelerometers; determine a physical activity type associated with the analyzed information; and store the determined physical activity type in a memory.

Abstract: An attachment unit includes a base plate, including a male connection element extending from a surface of the base plate. The attachment unit also includes a top plate, including a female connection element extending from a surface of the top plate, wherein the female connection element is configured to mate with the male connection element of the base plate. A tether having a first end may be connected to the base plate, and a second end of the tether may be connected to the top plate. An anchoring element may be configured to enable attachment of the base plate to a surface.
