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.

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.

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.

Abstract: A latching handle mechanism can secure a module containing a circuit interrupter. The mechanism has a lever mounted at a handle frame to rotate between a secured position and a released position for securing and releasing the module at a structure.
