A fluid sensing switch comprising a flex sensor having a plurality of conductive sensing areas and an energizing conductive area and a synchronous detector that detects a presence and a content of a bilge and produces a signal that is used to activate a pump.

A programmable arc fault circuit interrupter (AFCI) is provided. The programmable AFCI includes a dual resistive shunt array for developing inputs to an analog front end which in turn develops trigger quantities for input to a programmable processor. The programmable processor determines if the trigger quantities, singularly, or in the aggregate, exceed predetermined thresholds. Determining the predetermined thresholds are exceeded the processor issues a trigger command to momentarily energize a delatching coil, thus removing AC mains power from a load.

Programmable arc fault circuit interrupter (AFCI)

An electrochemical actuator drive system and method that provides for full control of an electrochemical pump system having at least three electrochemical actuators, including two valve actuators, and one pump actuator. The driving circuit is based on a standard H-bridge driving circuit wherein part of the circuit is shared among actuators. Because the system only needs to operate either the pump actuator or one of the valve actuators at any given time, part of the H-bridge driving circuit can be shared among the three actuators, thereby permitting the use of four half-bridge driving circuits.
