    • A system and method include a controller that reduces power dissipated by a switch, such as a source-controlled field effect transistor, when an estimated amount of power dissipated by the switch exceeds a predetermined threshold. Reducing the power dissipated by the switch prevents damage to the switch due to overheating.

In at least one embodiment, the controller includes a fail-safe, estimated power dissipation determination path that activates when the drain voltage data fails a reliability test. Additionally, in at least one embodiment, the controller includes a model of thermal characteristics of the switch. In at least one embodiment, the controller utilizes real-time estimated power dissipation by the switch and the model to determine when the estimated power dissipated by the switch exceeds a power dissipation protection threshold.

    • A power saving circuit is provided for a consumer device for disconnecting a mains power supply (2) from a supply circuit (including a transformer (18)) of the device when the device goes into a standby mode. The circuit comprises a high voltage switching module (16) interposed between the mains alternating current electrical power supply (2) and such a supply circuit. The circuit is reset by an actuable initiating component (12, 28) for generating a temporary signal to the high voltage switching module (16) to change the state of the switching module (16) to a conducting state. Then a sensing component ( 26 ) operates in a first mode responsive to the supply of mains alternating current to the supply circuit for maintaining the switching module (16) in a conducting state replacing the temporary signal. The sensing component (26) also operates in a second mode responsive to a target condition in the supply circuit indicative of the standby mode for changing the state of the high voltage switching module (16) to a non-conducting state.

    • A system and method are presented to detect and account for regenerated voltage in a three phase power source failures. The method involves monitoring a power source for phase voltage unbalances to determine the presence of a single phase failure. If the voltage unbalance caused by the single phase failure is restored before a sensing timer expires, a regenerated voltage condition is detected and retransfer to the power source is inhibited. Retransfer to the power source may be delayed by a period determined by a retransfer time value, in order to prevent transfer cycling between the preferred power source and an alternate power source. In addition, retransfer inhibiting may be terminated due to user interaction, power source voltage readings indicating a repair state, or by failure of an alternate source.

    • A compact non-contact multi-function electrical switch for use in an electrical box mounted on a wall has a one or more capacitance sensors for detecting a presence of a hand placed adjacent to the switch, as well as the directional movements of the hand along an X and/or Y axis and/or Z axis, and for generating data values, and a CPU for receiving the values and for determining which function is to be performed, such as calculating a power output in response to a first data bit.
