摘要:
A wave energy conversion apparatus comprising:—one or more movable buoyant members; one or more movable reaction masses located independent of the sea bed; said one or more reaction masses being suspended beneath said one or more buoyant members by a plurality of linkages, each linkage comprising an elongate non-rigid member which allows the or each buoyant member and the or each reaction mass to each move relative to one another; at least two of said linkages extending between the or one of said one or more buoyant members and the or one of said one or more reaction masses at an orientation inclined to the vertical; each linkage comprising, or being associated with, at least one extensible member whereby the effective length of each linkage can vary between an extended and a non-extended configuration such that the or each reaction mass can move with respect to the or each buoyant member in both a vertical and a horizontal direction, the extensible member providing a restoring force for biasing the linkage to a non-extended configuration whereby the linkage is maintained in tension, and one or more converters for converting kinetic energy of relative movement between the or each buoyant member and the or each reaction mass into useful power.

A power management system for a vehicle. The system may be flexibly configured using various arrangements of DC to AC inverters, DC to DC converters AC to DC converters, DC to AC converters and AC to AC converters, one or more batteries, and a control portion to provide an AC bus, a primary DC bus and a secondary DC bus. The control portion monitors the status of the buses, inverters and converters and controls the operation of the inverters and converters to supply and regulate the power supplied by the buses. The inverters and converters may be bidirectional, allowing power to be transferred between buses.

A power supply control system for a power supply having a first half-bridge leg and a second half-bridge leg. In the control system, a first plurality of drive signals are configured to operate a half-bridge as a forward leg while a second plurality of drive signals are configured to operate a half-bridge as a backward leg. A switch element is intermediate the first and second plurality of drive signals and the first and the second half-bridge legs, the switch element being adapted to operate the first half-bridge as a forward leg and the second half-bridge as a backward leg in a first operating mode, the switch element being further adapted to operate the first half-bridge as a backward leg and the second half-bridge as a forward leg in a second operating mode.

The present invention relates to technology for providing independent electrical power to a wide variety of electronic and/or mechanical systems, especially systems incorporating sensors and corresponding components that are used to take action based upon sensed information.
摘要:
A vehicle power and battery management system. The system includes a high-voltage DC bus, a first battery, a second battery, at least one bidirectional DC/DC converter, and a controller. The controller monitors the state of at least one of the high-voltage bus, the first battery and the second battery, and transfers energy between at least two of the high-voltage bus, first battery and second battery with the bidirectional DC/DC converter. A method employs the system.

摘要:
A system for cooling an environmentally sealed enclosure. The system includes an air channel extending generally vertically from a top surface of the enclosure to a bottom surface of the enclosure, at least one interior heat sink forming a barrier between the air channel and an interior portion of the enclosure, a fan disposed in the air channel and adapted to force air to flow through the air channel, and a plenum proximate the air channel to duct exhaust air away from the enclosure, wherein air flowing through the air channel cools the enclosure. A method employs the system.
