A portable power adapter includes a housing containing within it a battery chamber adapted to receive a selected battery pack, a circuit overload protector and a terminal connector selected to electrical couple to a selected DC load, and a mounting portion. A portable power adaptor may include an integrated voltage regulator, and a hermaphroditic SAE step connector. A portable power adaptor may include a plurality of power adapters electrically coupled to comprise a common power source and output.

A cable connector includes a first portion, a second portion, a first electrical prong, and a second electrical prong. The first portion defines a cavity. The second portion is adjacent to the first portion. The second portion includes a mounting structure defining a first cross-sectional void region within the cable connector and a second-cross-sectional void region within the cable connector opposite the first cross-sectional void region. The first electrical prong is disposed, in part, in the first cross-sectional void region and extends from the second portion. The second electrical prong is disposed, in part, in the second cross-sectional void region and extends from the second portion.

High-speed, hermaphroditic electrical connectors may be connected to form a hermaphroditic connector assembly that uses less space than existing connector assemblies. A housing can provide a first and second engagement feature that are intended to engage each other so that when two such connectors are rotated 180 degrees the engagement features allow two such connectors to mate together. Cables can be connected directly to the terminals so as to provide for improved electrical performance.

An elongated lighting module having an asymmetric illumination source formed from at least two rows of light emitting diodes (LEDs) that extend along the long axis of the module and are independently controllable. The illumination source is rectangular and oriented so that the rows of LEDs extend along the long axis of the module. The module has couplings at each end that allow additional modules to be interconnected therewith using a linking member and a clamp. The lighting modules are powered via a wiring harness that extends down a support pole to a power converter stack having LED drivers to control the modules. The asymmetric illumination source may be driven to change the beam angle and cutoff of illumination by independently adjusting the rows of light emitting diodes of the lighting module.

One example includes a signal connector system. The system includes a first connector comprising a first housing and first contacts formed from a self-passivating transition metal and configured to conduct an AC signal. The system also includes a second connector comprising a second housing and second contacts formed from the self-passivating transition metal and configured to electrically couple to a respective one of the first contacts to conduct the AC signal. The first and second housings can be coupled to enclose the signal connector and to create at least one fluid-filled channel between each of the electrically-connected first and second contact pairs in response to fastening the first and second connectors while submerged in a respective fluid to provide a resistive path in the at least one fluid-filled channel for providing signal isolation between each of the electrically-connected first and second contact pairs.
