Activity monitoring
First Claim
Patent Images
1. A method of activity monitoring, the method comprising:
- delivering data representative of at least one physical activity of an individual from a sensor of an activity monitor associated with the individual to a controller;
combining the data into at least two intermediate calculations by the controller, wherein a first calculation of the at least two intermediate calculations calculates a first quantity representing an orientation of the individual and a second calculation of the at least two intermediate calculations calculates a second quantity representing a delayed squared norm of an acceleration vector;
generating by the controller a score from the at least two intermediate calculations by multiplying the first quantity and the second quantity; and
recording the score as representative of the physical activity in a memory of the controller.

Abstract
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.
