Patent ID: 8459195

Claim:
Apparatus, including a bilge pump system, comprising: a self-priming diaphragm pump having a motor, and configured to respond to signaling to activate the self-priming diaphragm pump at predetermined intervals, and also configured to respond to corresponding signaling to deactivate the self-priming diaphragm pump; and a signal processing module configured with at least one processor and at least one memory including computer program code, the at least one memory and computer program code configured, with the at least one processor, to cause the signal processing module at least to: provide the signaling to activate the self-priming diaphragm pump at the predetermined intervals, and receive a signal containing information about an amperage draw from the motor when the self-priming diaphragm pump is activated and either (1) continue to run the self-priming diaphragm pump or (2) provide the corresponding signaling to stop the self-priming diaphragm pump from running based at least partly on the signal received that contains information about the amperage draw sensed.
