  • Patent number: 9353446
    Abstract: In some embodiments, an ICCP system includes an AC-DC rectifier receiving AC power from an AC power source and providing a DC output having a constant voltage or a constant current, a cathode connection electrically coupling the AC-DC rectifier to a structure to be protected by the ICCP system, current-emitting anodes arranged in parallel and receiving the DC output from the AC-DC rectifier, and a controller communicating with the AC-DC rectifier to set a maximum value for the constant voltage or constant current of the DC output. In other embodiments, an ICCP system includes a converter assembly including an AC-DC rectifier and a rectifier chassis enclosing and environmentally sealing the AC-DC rectifier. The ICCP system also includes an environmentally-sealed controller communicating with the AC-DC rectifier and an environmentally-protected Input-Output connection assembly.

  • Publication number: 20150229148
    Abstract: A blind-mate power charging station includes a receptacle, a base, and electrical circuitry. The receptacle includes a receptacle housing, an inner housing, and electrical contacts. The receptacle housing includes a pair of outer extensions, each outer extension tapering toward an outer extension tip. The inner housing is held within the receptacle housing and includes inner extensions forming parallel slots between pairs of inner extensions. Each electrical contact is held in one of the parallel slots by a pair of the inner extensions. The base receives the receptacle and mounts the receptacle to a stationary surface. The electrical circuitry couples the electrical contacts to an electricity source. The receptacle is shaped to receive a plug including a plug head and at least two prongs. Each prong engages one of the electrical contacts such that the receptacle provides electricity to the plug.

  • Patent number: 9077239
    Abstract: A circuit for connecting lower AC voltage-rated AC-DC power supplies with higher voltage power sources. A power line matching transformer connecting the source to the power supplies needs only to support the self-dissipation and output current mismatch between supplies. The circuit can also protect the line matching transformer from overheating in various fault scenarios.

  • Publication number: 20140352149
    Abstract: A liquid-cooled heat exchanger for electronic assemblies and a method of making the heat exchanger. The exchanger has a solid metal body in the form of an elongated flat plate to which the electronic assembly can be mounted, or a number of such plates formed in an L- or U-shaped configuration to enclose two or more sides of the assembly. The elongated body is formed by extrusion, with parallel enclosed longitudinal passages formed along a length of the body during the extrusion process. Transverse passages are drilled to intersect the extruded longitudinal passages. The longitudinal passages and transverse passages are plugged on at least one of their outside ends, and optionally at points along their lengths, to create desired patterns of liquid flow through the heat exchanger.

  • Publication number: 20130241284
    Abstract: A power management system for distributed power management from a power source to a plurality of power units, using a monitor bus to monitor total power usage on a branch to which the power unit is assigned, allowing power to be delivered if it won't result in a maximum current draw from the power source being exceeded, and denying access if it would. Each power unit adds a signal to the monitor bus proportional to the current it is drawing from the power source.
