摘要： A directional lighting fixture is disclosed. The directional lighting fixture includes a first housing, a lighting element, an optical element, and a driver board. The lighting element is located within the first housing and substantially aligned with a central axis of the directional lighting fixture. The lighting element is configured to generate visible light. The optical element is positioned directly in front of the lighting element. The optical element is configured to direct the visible light generated by the lighting element in a specific direction. The driver board is electrically coupled to the lighting element and includes an antenna element. The driver board is offset from the central axis of the directional lighting fixture. The antenna element is positioned to be at least flush with the lighting element.

摘要： A ballast circuit (6) comprises a rectifier circuit (8) and dual starting circuits (11, 13) that ensure ballast startup and lamp ignition regardless of input waveform half cycle. The first starting circuit comprises resonant circuit (10), and the second starting circuit includes a resistor (11). The resistor (11) comprising the second startup circuit provides a bias resistance to the second switches (72) to ensure ballast startup when an oscillating input waveform is in a negative phase.

摘要： A system and method enable a consumer to redeem loyalty points and coupons. The consumer is presented with a choice of electronic loyalty point redemption options and coupons, specific to the consumer and based on a behavioral purchasing rating system. The consumer's selections are transmitted to the participating vendor so the consumer can immediately pick up the consumer's selection from the vendor or utilize the desired coupons. The vendor can initiate new loyalty point redemption options dynamically. The vendor can accurately identify whether or not a promotion drove the consumer to the vendor's store through time and membership identification correlation.

摘要： In a lamp lighting ballast which generates a lamp lighting signal for a lamp, provided is a striation elimination circuit to increase the lumen output frequency for elimination of visual striations which may occur within the lamp. An even harmonic signal generator is configured to generate an even harmonic waveform, and an injection point is configured to receive the even harmonic signal into the lamp lighting system. The injection point is located at a location wherein the even harmonic signal alters the lamp lighting signal from a symmetric signal configuration to a high content even harmonic signal configuration prior to being received by the lamp.
