Abstract: A method of detecting a leakage path in an electronic device includes iteratively performing operations until an iteration condition is satisfied. The operations include causing a capacitor to be set to a known state, measuring a voltage level of the capacitor, and storing data indicating the measured voltage level. The operations also include causing the capacitor to be connected to a potential leakage path, remeasuring the voltage level of the capacitor, and storing data indicating the remeasured voltage level. The operations further include comparing the measured voltage level and the remeasured voltage level to detect leakage in the potential leakage path. The iteration condition is satisfied when a difference between the measured voltage level and the remeasured voltage level satisfies a voltage threshold or when a count of iterations performed satisfies an iteration threshold.

Abstract: Navigation of a solar vehicle is provided by obtaining a target geographic destination for the vehicle having one or more photovoltaic solar arrays; obtaining configuration data defining a target solar vector relative to a reference frame of the vehicle; identifying a current geographic positioning of the vehicle via a geo-positioning system of the vehicle, including a current geographic location and a current geographic orientation of the vehicle; identifying a current solar vector relative to the reference frame of the vehicle; and during at least a portion of a solar day, outputting a steering command for the vehicle for an indirect path from the current geographic location toward the target geographic destination that is based, at least in part, on a comparison of the current solar vector to the target solar vector. The steering command can be presented to a human operator or programmatically implemented by an autonomous or semi-autonomous vehicle.

Abstract: A float (1) suitable for use as a buoy or as a component for a wave-powered vehicle. The float (1) includes an upper member (12) whose height can be changed and/or which remained substantially vertical even when the float is in wave-bearing water. A low drag cable (2) suitable for use as a tether in a wave-powered vehicle has a streamlined cross-section and includes a tensile member (21) near the front of the cross-section, at least one non-load-bearing member (22) behind the tensile member, and a polymeric jacket (23). Wave-powered vehicles having a float (1), a submerged swimmer (3) and a tether (2) connecting the float and the swimmer, include a means for determining whether the tether is twisted; or a means (91) for untwisting the tether; or a pressure-sensitive connection (71, 72, 73) which can disconnect the tether when the vehicle is dragged downwards by entanglement with a whale; or a 2-axis universal joint securing the tether to the float or to the swimmer; or elastic elements which absorb snap loads created by the tether; or two or more of these.

Abstract: A power system for an unmanned surface vehicle is disclosed. In one embodiment, the power system includes a fuel cell, a fuel storage, and an air management system. The fuel cell includes a fuel cell stack. The fuel cell stack includes a fuel inlet, an air inlet, and an exhaust outlet. The fuel storage includes at least one fuel-storage module fluidly connected to the fuel inlet of the fuel cell stack. The fuel-storage module is a source of energy for the fuel cell. The air management system is fluidly connected to the air inlet and the exhaust outlet of the fuel cell. An air snorkel is part of the air management system and provides air to operate the fuel cell while the unmanned surface vehicle is deployed on a surface of a body of water. The air snorkel includes an intake and an exhaust.

Abstract: An adaptable modular power system (AMPS) is hierarchical in a number of ways. AMPS modules connect to a backplane, and one or multiple AMPS backplanes can form an AMPS domain. At the same time, the vehicle electronics is modular, with various payload boxes needing to communicate with each other. A common power and signaling cable is provided to interconnect payload boxes. A dedicated connector system is also provided so that AMPS modules may communicate, control, receive data, and supply and receive power.

Abstract: Equipment and methods that combine the use of wave powered vehicles and unmanned aerial vehicles (UAVs or drones). A UAV can be launched from a wave-powered vehicle, observe another vessel, and report the results of its observation to the wave-powered vehicle, and the wave-powered vehicle can report the results of the observation to a remote location. The UAV can land on water and can then be recovered by the wave-powered vehicle.

Abstract: This disclosure provides improved nautical craft that can travel and navigate on their own. A hybrid vessel is described that converts wave motion to locomotive thrust by mechanical means, and also converts wave motion to electrical power for storage in a battery. The electrical power can then be tapped to provide locomotive power during periods where wave motion is inadequate and during deployment. The electrical power can also be tapped to even out the undulating thrust that is created when locomotion of the vessel is powered by wave motion alone.

Abstract: This invention provides a vessel system and methodology that can be used to promote growth of phytoplankton in the oceans. Unmanned self-controlled wave-powered vessels are equipped with storage units for dispensing a fertilizer, and with sensors to monitor ocean conditions and effects. Fleets of vessels move autonomously by on-board processing of GPS and directional information, piloting a path that is coordinated by a central processing unit. The vessels travel through a defined target area, creating a detailed survey of chemical and biological characteristics that affect grown. The data are processed in a computer model to identify precise locations and precise amounts of fertilizer that will produce the best results. Projected benefits of fertilizing plankton include sequestering CO2 from the atmosphere, and enhancing the marine food chain to improve the fish stock in and around the treated area.
