1. A system comprising:
- a master power saving device configured for connection with a master load, said master power saving device configured to determine when said master load is in an operating condition and a non-operating condition based on said load demand of the master load, and wherein said master power saving device provides non-continuous power to said master load when said master load is in a non-operating condition; and
a slave power saving device configured for connection with a slave load, said slave power saving device configured to receive a signal from said master power saving device to turn off said slave load.

Abstract
A system is described including a master power saving device configured for connection with a master load. The master power saving device is configured to determine when the master load is in an operating condition and a non-operating condition, and the master power saving device provides non-continuous power to the master load when the master load is in a non-operating condition. A slave power saving device is configured for connection with a slave load. The slave power saving device is configured to receive a signal from the master power saving device to turn off said slave load.

9. A system comprising:
-
a sensor configured to determine whether a human is in the area of the sensor, said sensor providing a signal when a human is determined to be in the area; and a power saving device configured to receive said signal, said power saving device configured for connection with a load, said power saving device configured to determine when said load is in an operating condition and a non-operating condition based on a load demand, and wherein said power saving device provides non-continuous power to said load when said load is in a non-operating condition, and wherein said power saving device employs a first power saving strategy when said signal is received and a second power saving strategy when said signal is not received. - View Dependent Claims (10, 11, 12, 13, 14, 15)

16. A method for controlling an electrical load:
-
providing power to a load for a predetermined time; measuring a load demand; determining whether the load is turned on by said measured load demand; and repeating said steps of providing, measuring, and determining, wherein with each repetition said predetermined time is extended to a longer predetermined time until said load is determined to be on. - View Dependent Claims (17, 18, 19, 20)
