Latest Patents

Sanborn’s recent patent work addresses the control and safety of electric marine systems.

“Systems and Methods for Controlling High Voltage Systems for a Marine Vessel” describes a power control system for an electric marine propulsion system. The system monitors electrically isolated interlock circuits to check connectivity across portions of the power circuit. By measuring resistance, its controller can identify fault conditions, select an appropriate response, and control the power circuit accordingly.

“Marine Vessel Power Systems and Control Methods” concerns a vessel power system with separately mounted battery cell packs. It describes using low- and high-water sensors to detect a submersion event and a hardware controller that initiates an ingress-mitigation action. The design links battery-system monitoring with measures intended to protect the vessel and its power equipment.
