Automatic shut-off light system when user sleeps
First Claim
1. A method wherein at least one of a predetermined sleeping behaviors includes recognizing when a plurality of people enter an area a predetermined under surveillance and for providing variations in electrical power supplied to a plurality of devices in response to the detection of a sleeping person, said method comprising the steps of:
- tracking behavior of a person in the predetermined area the under surveillance;
comparing said tracked behavior with at least one of a plurality of predetermined sleeping behaviors to establish a behavior match; and
, if a match is established, adjusting the electrical power supplied to the plurality of said devices.

Abstract
A method and system for the automatic detection of a sleeping person and for adjusting electrical power supplied to a number of electronic devices; it includes a unit for observing the behavior of a person in a predetermined area under surveillance and a unit for analyzing output data from the observing unit to determine whether the observed behavior is associated with predefined sleeping behaviors. Upon recognition that the observed behavior indicates the sleeping state of a person, the electrical power supplied to the plurality of electronic devices is selectively adjusted according to predetermined criteria.
