US Patent 8152745 Activity monitoring

Sensors and methods for automatically detecting and recording physical activities of an individual are described. An event is detected, in which data representative of at least one physical activity of an individual is received from an activity monitor associated with the individual. The data is combined into at least two intermediate calculations. A score is generated from the at least two intermediate calculations. The score is compared to a predefined threshold to decide whether or not an event has occurred. Data representative of the event is recorded.
