Abstract: An electrical fixture mounting assembly is provided for quickly and easily mounting an electrical fixture to a brace assembly. The electrical fixture mounting assembly includes an electrical box, a brace assembly and a bracket. The brace assembly is mounted between joists located above an aperture in a ceiling. A bracket is snap-fitted onto the brace assembly. Protrusions on the bracket prevent substantial movement of the bracket during installation of the electrical box. Tabs on the bracket engage openings in the electrical box, thereby facilitating alignment of the electrical box with the bracket. An electrical box is secured to the brace assembly by the bracket and fasteners.

Abstract: An apparatus and method for controlling a plurality of lighting fixtures. A start controller provides power to the plurality of lighting fixtures. A control power timer connected to the start controller provides a first time period for illumination of the plurality of lighting fixtures, wherein the start controller is operable to interrupt power to the plurality of lighting fixtures when the first time period expires.

Abstract: A waterproof cover for electrical devices such as electrical outlets, receptacles, switches, ground fault circuit interrupters, dimmers, etc. The waterproof cover has snap-in modular cover plates which can be used either alone with one gang covers or outlet boxes, or ganged together in combination for use with two gang electrical covers or outlet boxes. The cover plate has a side edge which defines an overhanging interlock extending along a first length of the side edge and an underhanging interlock extending along a second length of the side edge. The arrangement is such that the overhanging interlock can interlock with an underhanging interlock and the underhanging interlock can interlock with an overhanging interlock of a second similar cover plate to form a two gang cover plate for a two gang weatherproof cover. Alternatively, the overhanging interlock can interlock with an underhanging interlock and the underhanging interlock can interlock with an overhanging interlock of a one gang waterproof cover.

Abstract: A cover for a wall mounted enclosure having a faceplate with first and second sides and an aperture extending through the plate. A screw retention assembly is coupled to the plate adjacent the aperture by a flexible mechanism that is more flexible than the plate. The flexible mechanism is bendable with respect to three separate axes relative to the faceplate, allowing the screw retention assembly to float with respect to the plate about those axes. This enables the faceplate to fit flush against the wall and the screw retention assembly to fit flush against the enclosure even when the enclosure is misaligned or depressed relative to the wall.

Abstract: A system and method are provided for ensuring increased accuracy of individual relays (e.g., within a control system including a sensor) to close substantially coincidentally with respect to a current zero-crossing of an incoming power supply waveform. To determine timing of contact operation, a microcontroller operates the contacts in response to one of a series of test pulses, and determines the amount of time required for contact operation. The difference between timing of contact operation and zero-crossing is determined and adjusted to offset errors incurred by microcontroller threshold variations and power supply voltage variations. The calibrated value is then provided to the sensor in order to extend sensor life.

Abstract: An ignitor monitoring device is provided which is enclosed within a housing to allow for portability while testing high intensity discharge (HID) luminaires. The device is placed in the lamp socket with the lamp removed, and measures the open circuit voltage across the ignitor, as well as the ignitor's ignition pulse. If the ignitor monitoring device detects adequate voltage to enable ignition of the lamp, the LED illuminates; otherwise, the LED fails to illuminate, and the operator can begin troubleshooting by replacing the ignitor and re-testing the luminaire, or testing the source, among other troubleshooting methods known in the art. A first housing employs a plunging mechanism that allows the operator to insert the monitoring device into the lamp socket with ample pressure to ensure electrical conduction between the device and the luminaire.

Abstract: A double density channel bank architecture compatible with an existing D4 backplane and D4 channel units transmits or receive PCM data on the PAM bus, while simultaneously transmitting or receiving PCM data on the PCM bus. A double density channel unit (CU) provides data for two transmit and two receive T-1 timeslots to increase the capacity of a D4 channel bank from 48 channels to 96 channels. Channel bank timing of PCM data on the PAM bus provides isolation of PCM data and PAM signals on PAM bus. Double density transmit and receive units each support an additional DS1. The receive unit transmits a signal on both CU channels to indicate T-1 failure and to commence trunk processing.

Abstract: A micro porous gas breather/filter assembly can be coupled to a housing of an electrical enclosure. The filter assembly has a two portion housing with the filter disposed between them. An adhesive on the filter attaches the filter to one or both portions of the housing. The filter allows gas to pass from the enclosure through the filter and to the atmosphere, but prohibits liquid from passing into the enclosure device. By filtering gases and liquids in this manner, the filter vents explosive and/or flammable gases from an electrical enclosure, while preventing liquid and other contaminants from entering the enclosure and damaging the electrical device or its wiring.
