Abstract
A device includes a load sensor configured to measure a load demand that indicates that a load is operating in an active state or an inactive state. A load switch is configure to selectively supply electric energy to the a load in accordance with a load control signal. A controller in communication with the load switch and the load sensor is configured to compare the load demand to a load threshold, generate the load control signal based at least in part on the load demand relative to the load threshold, and transmit the load control signal to the load switch when the load demand is substantially equal to or greater than the load threshold. The controller is further configured to determine the load threshold based at least in part on the load demand when the load is operating in either the active state or the inactive state.

21. A device comprising:
-
a load sensor configured to measure a load demand, wherein the load demand indicates that a load is operating in at least one of an active state and an inactive state; a load switch configure to selectively supply electric energy to the a load in accordance with a load control signal; and a controller in communication with the load switch and the load sensor, wherein the controller is configured to compare the load demand to a load threshold, generate the load control signal based at least in part on the load demand relative to the load threshold, and transmit the load control signal to the load switch when the load demand is substantially equal to or greater than the load threshold, and wherein the controller is configured to determine the load threshold based at least in part on the load demand when the load is operating in at least one of the active state and the inactive state. - View Dependent Claims (22, 23, 24, 25, 26, 27, 28, 29, 30)

31. A power-saving device comprising:
-
a load sensor configured to measure a load demand; and a controller in communication with the load sensor and configured to compare the load demand to a load threshold and enable the load if the load demand is substantially equal to or greater than the load threshold, wherein the controller is configured to determine the load threshold during a time when a load is operating in an inactive state. - View Dependent Claims (32, 33, 34, 35, 36, 37, 38)

39. A method comprising:
-
determining a load threshold when a load is operating in at least one of an active state and an inactive state; comparing the load threshold to a load demand; enabling the load if the load demand is substantially equal to or greater than the load threshold; and disabling the load if the load demand is less than the load threshold. - View Dependent Claims (40, 41, 42)
