Sensor methods and apparatus
First Claim
1. A method of identifying a sensor signature indicative of an operative state of a device, the method comprising:
- providing a plurality of sensors in a training space, each sensor operable to measure a different characteristic;
determining the values of one or more attributes of the training space;
receiving a plurality of sensor signals, each sensor signal indicative of a different characteristic measured by one of the plurality of sensors in the training space;
receiving device operation information comprising the type and operative state of a device in the training space;
determining, from the received plurality of sensor signals and the received device operation information, a sensor signature comprising values of a combination of different measurable characteristics that are indicative of an operative state of the device;
associating the determined sensor signature with the determined values of the one or more attributes of the training space; and
storing the determined sensor signature together with the associated values of the one or more attributes.

Abstract
There are described methods and systems for identifying an operative state of a device using sensor signatures and for identifying such sensor signatures. The methods may comprise determining, from a received plurality of sensor signals and received device operation information, a sensor signature comprising values of a combination of different measurable characteristics that are indicative of an operative state of a device; and associating the determined sensor signature with attributes of a training space. Such sensor signatures may be used to identify the operative state of a device or appliance in a monitoring space.
