Activity monitoring
First Claim
Patent Images
1. An activity monitor for attachment to an entity, the monitor comprising:
- a measurement unit including a plurality of 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;
receive an input from a user indicating presence of external motion effects on the entity to which the monitor is attached;
in response to the input, apply a correction calculation to the sensor signals to form corrected signals, in order to remove the external motion effects from the sensor signals; and
store the corrected signals.

4. A method of monitoring activity of an entity using a plurality of motion sensors which are operable to produce respective sensor signals indicative of motion experienced thereby, the method comprising the acts of:
-
receiving the sensor signals; processing the signals in accordance with a predetermined method; receiving an input from a user indicating presence of external motion effects on the entity; in response to the input, applying a correction calculation to the sensor signals to form corrected signals in order to remove the external motion effects from the sensor signals; and storing the corrected signals. - View Dependent Claims (5, 6)
