Abstract
An activity monitor is provided that corrects for the effects of motion external to the entity being monitored. For example, the activity monitor can overcome the effects of vehicular travel.
Claims12
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.
4 more elements
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;
- and
- applying a correction calculation to the sensor signals to form corrected signals in order to remove external motion effects from the sensor signals.
1 more element
A monitor for attachment to an entity, the monitor comprising:
- means for generating sensor signals indicative of motion of the entity;
- means for processing the sensor signals in accordance with a predetermined method;
- and
- correction means for applying a correction calculation to the sensor signals to form corrected signals in order to remove external motion effects from the sensor signals.
