Abstract:
A light fixture can include at least one light fixture component. The light fixture can also include at least one sensor that measures at least one parameter associated with the at least one light fixture component. The light fixture can further include a prognostic and health inonltoring (PHM) system coupled to the at least one sensor, where the PHM system analyzes at least one measurement, made by the at least one sensor, to identify at least one factor that affects longevity of the at least one light fixture component.
Abstract:
A system can include at least one circuit breaker. The system can also include a prognostic and health monitoring (PHM) system. The PHM system can include at least one measuring device that measures at least one parameter associated with the at least one circuit breaker. The PHM system can also include a controller that receives measurements made by the at least one measuring device and analyzes the measurements to evaluate a performance of the at least one circuit breaker. The measurements can be made while the at least one circuit breaker is in service.
Abstract:
A ground fault circuit interrupter (GFCI) breaker testing system can include an enclosure having at least one wall that forms a cavity. The system can also include at least one GFCI breaker disposed within the cavity. The system can further include a sensing circuit assembly having at least one switch, where the at least one switch is electrically coupled to the at least one GFCI breaker. The system can also include a user interface assembly disposed, at least in part, outside the cavity, where the user interface assembly is coupled to the sensing circuit assembly, where the user interface assembly instructs the at least one switch to test the at least one GFCI breaker.
Abstract:
A power distribution module (PDM) can include an input portion configured to receive high-voltage (HV) power from a power source. The PDM can also include a power transfer device electrically coupled to the input portion, where the power transfer device is configured to generate at least one low-voltage signal using the HV power. The PDM can further include an output section electrically coupled to the power transfer device and including a number of output channels. The PDM can also include at least one switch disposed between the output section and the power transfer device, where the at least one switch has an open position and a closed position. The PDM can further include a controller communicably coupled to the at least one switch, where the controller operates the at least one switch between the closed position and the open position based on a power demand measured at the output section.
Abstract:
A light fixture is described herein. The light fixture can include at least one light source. The light fixture can also include a controller coupled to the at least one light source, where the controller controls an output of the at least one light source based on a location of the light fixture in a facility.
Abstract:
A system for monitoring one or more aspects of a fuse tube assembly (22) of a fuse cutout (12) comprises: a housing (102) structured to be disposed adjacent to, and coupled to the fuse tube assembly (22); a power source (120) disposed in the housing (102); a processing unit (122) disposed in the housing (102) and electrically coupled to the power source (120); and a motion detecting unit (126) disposed in the housing (102) and electrically coupled to the processing unit (122), the motion detecting unit (126) being structured to detect one or both of position or movement of the housing (102).
Abstract:
A housing for a gas sensor module is described herein. The housing can include an outer portion and an inner portion disposed within the outer portion. The outer portion can include at least one wall forming a first cavity. The outer portion can also include an inlet tube coupling feature disposed at a first location in the at least one first wall, and an outlet tube coupling feature disposed in a second location in the at least one first wall. The inner portion can include at least one second wall forming a second cavity, and a distribution channel coupling feature disposed at a third location in the at least one second wall. The inner portion can also include a receiving channel coupling feature disposed in a fourth location and a tuning fork coupling feature disposed at a fifth location in the at least one second wall.

A cap for a gas sensor module is described herein. The cap can include at least one wall forming a cavity having a first portion and a second portion. The cap can also include an inlet tube coupling feature disposed in the at least one wall, where the first location is adjacent to the first portion of the cavity. The cap can further include an outlet tube coupling feature disposed in the at least one wall, where the second location is adjacent to the second portion of the cavity. The cap can also include a distribution channel coupling feature disposed in the at least one wall, where the third location is adjacent to the first portion of the cavity. The cap can further include a receiving channel coupling feature disposed in the at least one wall, where the fourth location is adjacent to the second portion of the cavity.
Abstract:
A luminaire includes a body including a lighting compartment and a bezel rim around at least a portion of a perimeter of the body. The luminaire also includes clamping plates that extend a length of the luminaire. As the clamping plates are secured in a lighting compartment of the luminaire, they provide a clamping force to secure an LED circuit board in the lighting compartment. A base of the lighting compartment may also serve as a heatsink for the LED circuit board. A low-profile luminaire according to such features is also provided.
Abstract:
A lighting fixture includes a housing bracket and pair of side rails, each side rail located adjacent opposite sides of the housing bracket. Further, the lighting fixture includes a light guide that is oriented horizontally and securely retained by the pair of side rails. Furthermore, the lighting fixture includes a plurality of light sources that are disposed on or within a cavity defined by at least one of the side rails such that the plurality of light sources are positioned in close proximity to and along an edge of the light guide. The light guide receives light emitted by the plurality of light sources through the edge of the light guide and emits the light through a major surface of the light guide. Further, the lighting fixture includes an end plate and an end cap disposed on each lateral end of the lighting fixture.
