Abstract: The present invention is directed to a power supply circuit for controlling a load which, for example, includes both a gas-discharge lamp and an auxiliary load. The power supply circuit includes a ballast circuit for limiting current supplied to the gas discharge lamp. The auxiliary load, such as an occupancy sensor, is connected to receive an alternating current signal from a transformer winding, inductor coil, or other suitable portion of the ballast circuit. The power supply circuit includes a rectifier for rectifying the alternating current signal to provide a stable, low-voltage direct current signal to drive the auxiliary load.

Abstract: Disclosed herein is an awning support brace for a retractable awning of the type having a remote edge supported by a plurality of retractable arms extending outwardly from a base; the stabilizer including a frame member having a pair of ends with a first pivot arrangement on one end and a second pivot arrangement on the other end, the first pivot arrangement being attachable to the remote edge and the second pivot arrangement being attachable to a secure location beneath the remote edge, the brace being arranged to minimize deflections caused by wind that would otherwise damage the base while permitting the arms to deflect in a manner to absorb forces caused by the wind.

Abstract: A fluorescent lamp control system operable from either an AC power supply of a first frequency or a power supply of a second frequency and which operates the lamp in a dimmed condition when the power supply is that of the second frequency.
