Abstract: A pop-up enclosure system (30) for electronic equipment, includes a receptacle (31) adapted for mounting in a work-surface (15) and containing one or more electrical outlets (32) for connection of equipment thereto, and a bezel (33) supported by the receptacle and adapted for countersinking in said work-surface. A top plate (34) is dimensioned for closing an opening defined by the bezel, and a hinge (35) is mounted at an edge of the top plate and the bezel for hingedly attaching the top plate to the bezel so as to allow rotation of the top plate from a closed position to a fully open position wherein the edge of the top plate abuts an upper surface of the bezel. A releasable resilient opening force (37) is fixed to the receptacle and articulated to the top plate for opening the top plate.

Abstract: A ceiling speaker mountable in a ceiling tile for mounting in a suspended ceiling of a room, includes a central woofer, and at least four surrounding pivoting tweeters that are independently adjustable so as to provide broad flat coverage throughout the room. A crossover network directs low frequency signals to the woofer and high frequency signals to the tweeters and an optional stereo separator circuit directs left and right signals to different pairs of the tweeters. A method for adjusting sound dispersion produced by the ceiling speaker is also disclosed.

Abstract: A rewindable electrical cable extension device includes a housing having first and second exit ports, and a cable having first and second ends defining opposing extremities of first and second contiguous cable sections having a common junction anchored to a rotating spool. The first end protrudes through the first exit port, and the second end is fixedly mounted in association with the second exit port. The first cable section is wound on a spool that is configured to rotate within the housing. The second cable section is wound in an opposite direction to the first section so that pulling on the first end unwinds and extracts the first cable section from the housing and uncoils the second cable section within the housing without rotating the second end of the cable.
