Light controller with occupancy sensor
First Claim
1. A device for signaling the sensed presence of an occupant within an area, comprising:
- detecting means for sensing the presence of the occupant within the area;
transmitting means for producing more than one occupancy signal transmission, each signal transmission corresponding to the currently sensed presence of the occupant by said detecting means; and
means for inhibiting for a first predetermined period of time production of at least one signal transmission following each produced signal transmission.

Abstract
A system for controlling the intensity of a lamp including a remote sensing device for detecting the presence of an occupant within an area. The device also transmits a signal based on the currently sensed presence of the occupant. After each transmission of an occupancy signal, the device is inhibited from further transmission for a first predetermined period of time to limit power consumption requirements by the battery powered device. The system also includes a light controller responsive to the transmitted occupancy signal for controlling the level of illumination by the lamp. In the absence of a transmitted occupancy signal within a second predetermined period of time, the light controller will instruct the ballast to reduce the level of illumination by the lamp. In the absence of an occupancy signal being transmitted within a third predetermined time period, the light controller will instruct the ballast to turn off the lamp.
