Abstract:
A testing device for a meter socket assembly, including breaker load lugs, includes a base unit having a plurality of test probes, a ground node, and a breaker node having a plurality of breaker probes. To perform the test, the base unit is inserted into a jaw meter socket such that each of the plurality of test probes are in contact with jaws of the jaw meter socket, at least two of the plurality of breaker probes are in contact with each of a plurality of breaker load lugs of a main breaker, and the breaker node is electrically connected to the base unit. The testing device determines the jaw type of the meter socket assembly and can output results of tests relating to phase to phase, phase to ground, crossed cables, and interruption of electrical paths. The testing device can output results of the test audibly and visually.

Abstract:
Systems, methods, and devices for reducing glare or pixilation associated with LEDs are disclosed. The disclosure relates to a light module that includes a cover panel that reduces contrast in the light emitted by LEDs. The cover panel can be mounted on a substrate which can include a plurality of LEDs. Apertures in the cover panel are aligned with each of the LEDs and any optic that may be disposed over each LED. A first portion of the light emitted from the LEDs passes through the optic only and into the environment to be illuminated. A second portion of the light emitted from the LEDs passes through both the optic and the cover panel before passing into the environment to be illuminated. The cover panel can be diffuse and can include various characteristics including textures, objects, and angled surfaces that assist in scattering light.
Abstract:
A non-explosive tension release actuation device includes an initiator system and a housing base attached to the initiator system. The device also includes a carriage assembly positioned at least partially within the housing base. The carriage assembly includes a carriage unit, a first jaw, a second jaw, a first rocker arm, and a second rocker arm. The first rocker arm and the second rocker arm are attached to the carriage unit and to the initiator system. The device further includes a load attachment unit positioned at least partially within the carriage unit and between the first jaw and the second jaw. The first jaw and the second jaw are configured to swing away from the load attachment unit in response to a downward motion of the carriage unit relative to the housing base.
Abstract:
Managing solid-state luminary (SSL) fixtures over power line carrier (PLC) networks is described herein. Devices provided in this description include SSL arrays, and converter circuitry coupled to drive the SSL arrays. More specifically, the converter circuitry is adapted to convert input voltage received from a power distribution network into a level suitable for driving the SSL arrays. The devices also include (PLC) modems for coupling to PLC networks, and coupled to the converter circuitry. In particular, the PLC modems interface the converter circuitry to the PLC networks.
Abstract:
A light source, for example a light emitting diode, can emit light and have an associated optical axis. The source can be deployed in applications where it is desirable to have illumination biased laterally relative to the optical axis, such as in a street luminaire where directing light towards a street is beneficial. The source can be coupled to an optic that comprises an inner surface facing the source and an outer surface that is opposite the inner surface. The inner surface can comprise a refractive surface that receives light headed away from the optical axis of the light source, for example opposite the street. The refractive surface can form the received light into a beam. The outer surface of the optic can reflect the beam back across the optical axis, for example so that light headed away from the street is redirected towards the street.
Abstract:
A manifold within an explosion-proof enclosure is described herein. The manifold can include an inlet duct coupled to an air moving device, where the inlet duct can receive exhaust air from the air moving device. The manifold can further include an outlet duct that includes a perimeter and at least one channel, where the outlet duct can send the exhaust air outside the explosion-proof enclosure, where the perimeter of the outlet duct is coupled to a first portion of an inner surface of an outer wall of the explosion-proof enclosure, and where the first portion of the inner surface includes at least one aperture that traverses the outer wall. The manifold can also include a body that includes a cavity, where the body couples the inlet duct to the at least one channel, and where the exhaust air flows from the inlet duct through the cavity to the outlet duct.

An electrical connector having an active cooling system is described herein. The electrical connector can include a conductor having an electrically conductive pin, and a conductor receiver slidably coupled to the conductor. The conductor receiver can include a wall having an electrically conductive material forming a cavity into which the pin is received. The conductor receiver can also include an insulating sleeve mechanically coupled to the wall. The conductor receiver can further include a heat sink mechanically coupled to the insulating sleeve and a channel that collects heat absorbed by the heat sink. The heat collected by the channel can be vented outside the conductor receiver. Alternatively, the wall of the conductor receiver can be coupled to an insulator and have at least one aperture that vents heat from the cavity to the insulator.
