Abstract:
A load control device for improving energy efficiency of a heating, ventilating, and air-conditioning (HVAC) system by controlling shed times of a compressor of the HVAC system. The load control device includes a compressor cutoff switch, a sensing circuit, and a processor. The processor determines a subsequent mandatory shed time based upon a previous shed time, a previous run time, and a minimum run time. A subsequent mandatory shed longer than the previous mandatory shed time causes a subsequent run time to be increased, thereby increasing system efficiency.
Abstract:
A magnetic component and a method for manufacturing a low profile, magnetic component. The method comprises the steps of providing at least one sheet, coupling at least a portion of at least one winding to the at least one sheet, and laminating the at least one sheet with at least a portion of the at least one winding. The magnetic component comprises at least one sheet and at least a portion of at least one winding coupled to the at least one sheet, wherein the at least one sheet is laminated to at least a portion of the at least one winding. The winding may comprise a clip, a preformed coil, a stamped conductive foil, or an etched trace using chemical or laser etching. The sheet may comprise any material capable of being laminated and/or rolled, including, but not limited to, flexible magnetic powder sheets.
Abstract:
Magnetic components including pre-formed clips are described that are more amenable to production on a miniaturized scale. Discrete core pieces can be assembled with pre-formed coils and physically gapped from one another with more efficient manufacturing techniques.
Abstract:
A seismic clamp for securing a utility pipe to a rigid rod includes a pipe holder that secures the utility pipe to the seismic clamp. A rod fitting secures the rigid rod to the seismic clamp so that the rigid rod extends transverse to the utility pipe. A spacer is disposed between the holder and the rod fitting. The spacer inhibits the rigid rod from contacting the utility pipe when the utility pipe is secured to the seismic clamp, and the rigid rod is secured to the seismic clamp.
Abstract:
Methods and systems for performing network reconfigurations for networks including one or more renewable energy devices are described herein. In one exemplary embodiment, a network reconfiguration engine is used to determine an energy level of one or more renewable energy devices within the network. The reconfiguration engine is then capable of determining an optimal path for the network reconfiguration such that a least portion of the network's load is impacted, as well as a minimal number of switching operations are needed. The optimal path also, in one embodiment, includes performing a resiliency estimation for the post-network reconfiguration topology. An updated relay setting for the post-network reconfiguration topology is determined, and a status of any other engines associated with the reconfiguration is determined, after which the network reconfiguration is performed.
Abstract:
Explosion-proof enclosures having one or more flame paths and one or more grooves for protecting the flame paths and/or assisting in accessing and measuring the flame paths, and methods for coating the explosion-proof enclosures.
Abstract:
A system for detecting theft of electricity from a utility includes a controller configured to receive electricity readings from a metering device configured to sense electricity flowing therethrough to a primary load, disaggregate the electricity readings from the metering device into electricity readings for sub-loads identified within the primary load, and compare the disaggregated electricity readings for the identified sub-loads to expected electricity readings for each identified sub-load. The controller is also configured to calculate a level of interference with an electrical path through the metering device based on an extent that the disaggregated electricity readings deviate from the expected electricity readings and output to the utility the level of interference with the electrical path.
Abstract:
A light fixture can include a housing comprising at least one wall that forms a cavity, wherein the housing complies with applicable standards for a hazardous environment. The light fixture can also include an antenna assembly disposed on an outer surface of the housing. The antenna assembly can provide communication with another device within the hazardous environment without compromising the applicable standards for the hazardous environment.
Abstract:
An edgelit recessed luminaire includes a housing that defines an inner cavity and has a pair of side panels. Each side panel includes one or more torsion spring receivers. Further, the edgelit recessed luminaire includes a light engine that includes torsion springs that are pivotally coupled to the light engine via torsion spring brackets. The light engine is removably coupled to the housing such that in an open position, the light engine is suspended from the housing via the torsion springs providing access to the inner cavity and in a closed position, the light engine covers the inner cavity of the housing. Alternatively, a linear light module is removably coupled to the housing.
Abstract:
Systems and methods associated with a multi-producer single consumer lock-free queue capable of accumulating traces is described herein. In a non-limiting embodiment, data is determined to be allocated, and a first head/tail pair indicating a location along a queue is received, the location indicating where a data bucket is able to be placed. A first data bucket to use for storing the data is determined, and the data is stored using the first data bucket. The first data bucket is then placed on the queue, and a first instruction to decrement a first reference count for the first head/tail pair is generated.
