Activity monitoring
First Claim
Patent Images
1. An activity monitor f or attachment to an entity, the monitor comprising:
- a measurement unit including one or more motion sensors operable to produce respective sensor signals indicative of motion experienced thereby; and
a processor operable to;
receive the sensor signals from the measurement unit;
process the sensor signals in accordance with a predetermined method; and
apply a correction calculation to the sensor signals to form corrected signals, in order to remove external motion effects from the sensor signals.
