Abstract: A weather-resistant, tear-resistant banner of polycarbonate material is mounted to a post or pole using a channel member and a bracket system that readily allows changing of seasonal banners. The polycarbonate die-cut banner is suspended along a single edge by the channel member which slides into the bracket. The bracket can be banded to virtually any post or pole regardless of shape or size.

Abstract: A transformer casing is disclosed that allows access to the front and side of the transformers while providing a lighter cover.

Abstract: A method of reducing the volume of oil required by a transformer is described. The sides of a transformer are embossed by use of a metal roller press causing indentations into the metal sides of the transformer.

Abstract: A lighting control system for municipalities and recreation departments is disclosed. The lighting system can process payments so that a user can pay for usage of a recreational facility at the time of need.

Abstract: A power supply device comprising an advanced harmonic current quashing (AHQ) and current pulse multiplier (CPM) (AHQ/CPM) three-phase transformer having: a primary winding placed around a magnetic core and having three primary winding input leads to connect a three phase power supply; and a plurality of secondary windings placed around the magnetic core in a predetermined winding turns configuration to generate a plurality of three phase outputs, where each three phase output of the plurality of three phase outputs has a different phase angle from all other three phase outputs, with each unique phase angle associated with a three phase output of a corresponding secondary winding being determined based on the winding turns configuration utilized for the corresponding secondary winding. A variable frequency drive (VFD) having 3N converters/inverters coupled to the secondary windings outputs exhibit substantially reduced harmonic currents and a current pulse number of greater than 6N.

Abstract: A starter stopper for use with a high intensity discharge (HID) lighting source includes a timer and switch. The timer controls the durations of on-time and off-time periods during an energizing period. The starter stopper connects the HID lighting source to power to start the HID lighting source during on-time periods, and disconnects the HID lighting source from the power to start the HID lighting source during off-time periods. A method of starting and stopping an HID lighting source includes initiating an energizing period in response to application of power to a starter stopper, enabling the HID lighting source to be connected to power to start the HID lighting source during on-time periods by the starter stopper, enabling the HID lighting source to be disconnected from the power to start the HID lighting source during off-time periods by the starter stopper, and stopping the energizing period in response to removal of the power to the starter stopper.

Abstract: A method, device, and plurality of circuit enhancements for a rectifier system that enable reduction in lower order and higher order harmonics, without substantially reducing the rectifier's direct current output voltage. The rectifier system comprises a phase shifting primary transformer subsystem and a multi-pulse rectifier. At least one series impedance path is coupled to one of three input terminals/leads of the transformer subsystem and conducts one phase of three phase currents from a power supply to the transformer subsystem. The series impedance path provides low impedance to the 1st harmonic and substantially higher, inductive impedance to higher harmonics of the power supply frequency.

Abstract: A self-monitoring transformer is disclosed. The transformer uses sensors embedded in the coils to determine the expected lifespan of the insulation, as well as other operating parameters, and communicates that information to an external system.

Abstract: Different configurations of transient voltage quashing (TQ) transformers, harmonic current quashing (HQ) transformers, and transient voltage and harmonic current quashing (THQ) transformers include one or more of: a tertiary winding radially placed between the primary and secondary windings, with a surge suppressors coupled thereto, which quashes transient voltages in the transformer and any output device attached to output leads of the tertiary or secondary windings; and an arrangement of the secondary windings, separated by at least a second type intra-winding insulation, into one or a plurality of output winding groups, each used to provide power to N serially-connected output devices that exhibit known/expected output voltage characteristics.

Abstract: A compact luminaire which includes a housing, a ballast, and a first and second electrical component. The housing has a back and a perimeter wall which extends generally perpendicularly from the back. The perimeter wall has a top wall portion, a bottom wall portion disposed in a downward direction with respect to the top wall portion and sidewall portions connecting the top wall portion and the bottom wall portion. The ballast is mounted to the back adjacent the bottom wall portion and is substantially equidistant to the side wall portions and the first and second electrical components are mounted to the housing on opposite sides of the ballast in a balanced fashion.

Abstract: A receptacle assembly for a twist-lock photocontrol that is mounted on a luminaire housing. The assembly includes a receptacle and a spring clamp. The receptacle has a disc portion with a hub extending from the central portion of the back side, a perimeter side wall with a castellated bottom edge that engages stops on the luminaire housing. Three fingers extend from the back side of the disc and terminate at a lip edge.
