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.

Abstract: An example system includes a sensor configured to generate a human-in-area signal. The human-in-area signal may indicate that a human is in an area of the sensor. The system may further include a power-saving device in communication with the sensor and configured to receive the human-in-area signal. The power-saving device may provide power to a load based at least in part on a load demand and in accordance with the human-in-area signal.

Abstract: A system is described including a means for receiving a potential and selectively supplying the potential to a load. The receiving and supplying means being responsive to a load control signal to supply the potential to the load when the load control signal is present. The system also includes a means for measuring a load demand. Also included is a means for controlling the receiving and supplying means. The controlling means continuously providing the load control signal when the load demand is greater than a predetermined threshold. The controlling means temporarily providing the load control signal to determine the load demand when the load demand is less than the predetermined threshold.
