The port is also capable of dynamically interfacing to any USB compliant peripheral device.

Abstract: A method and apparatus for automatic compensation of insertion loss in signals transmitted over conductors is presented. The present invention is particularly applicable to the transmission of signals over long lengths of CAT-5 or similar twisted-pair cables. A reference signal having a known form and strength (e.g. a pulse signal) is provided to each pair of conductors carrying a component of a signal from a transmitter to a receiver. The receiver includes adjustable gain amplifiers for each conductor pair over which a component of the signal is transmitted. The gains of the amplifiers are initially set at an initial level (e.g., their maximum gain) to allow detection of the reference signal. Once the reference signal is detected in a conductor pair, the amplifier gains are adjusted such that the level of the reference signal is restored approximately to its original form and strength.

Abstract: A cable retractor is provided. In accordance with at least one embodiment, the cable retractor is articulate, comprising an articulate housing which comprises a cable stop housing pivotably coupled to a pulley housing. In accordance with at least one embodiment, the cable retractor also comprises a first pulley assembly coupled to the pulley housing, an end cap coupled to the pulley housing, a spring coupled to the end cap, and a second pulley assembly coupled to the spring. In accordance with at least one embodiment, the first pulley assembly and the second pulley assembly are disposed within the pulley housing. In accordance with at least one embodiment, a cable stop assembly is coupled to the cable stop housing. In accordance with at least one embodiment, several of the parts are separable to facilitate installation or replacement of a cable.

Abstract: A method and apparatus for providing a loudspeaker assembly is provided. In accordance with at least one embodiment, apparatus is provided comprising a ground plane, a loudspeaker driver mounted in a loudspeaker driver aperture of the ground plane, and a grille positioned relative to the ground plane such that a distance between the grille and the ground plane decreases with increasing distance from the loudspeaker driver. The loudspeaker assembly can be used to replace ceiling tiles having any size or configuration, and can also me mounted in other surfaces, such as ceiling walls, floors, table tops, etc. made of drywall, hard decking, wood, stone, cement, glass, or any other material or type of construction, or configured in a stand-alone loudspeaker frame or cabinet. The loudspeaker assembly of the present invention can be mounted in any orientation.

Abstract: A triangular waveform generator includes a square waveform clock circuit and an integrating circuit. The integration circuit receives input from the square waveform clock circuit and generates a triangular waveform output. A feedback circuit is operatively connected to the integrating circuit to reduce the audio band noise content in the triangular waveform output. The feedback circuit acts as a DC balance without significant sacrifice in the linearity of the triangular waveform output.

Abstract: An external power supply housing configured for multiple mounting options. In one or more embodiments, the housing of the invention comprises channels configured to accept straps for mounting said housing to a support structure by means of those straps. In one or more embodiments, the housing of the invention comprises threaded inserts configured to mount said housing to a support structure by means of threaded fasteners. In one or more embodiments, the housing of the invention comprises a snap engagement portion configured to snap engage a mating power supply caddy for mounting the housing to the caddy.

Abstract: The present invention comprises a method and apparatus for installing a tile-mounted ceiling speaker that combines the ease of installation of a lay-in speaker system with the visual appearance of a tile-mounted speaker system. In one or more embodiments, the apparatus of the present invention includes a support frame, back box assembly configured for installation on top of a ceiling tile, a ceiling ring configured to be mounted in an opening in a ceiling tile, and a loudspeaker cartridge configured to be mounted to the support frame through the ceiling tile opening.

Abstract: A method and apparatus for secure distribution of digital content is provided. In accordance with at least one embodiment, an intermediate device maintains an authorized content sink list which it uses to allow reauthorization of a first content sink for access to first content from a first content source when the first content sink has a first content sink entry on the authorized content sink list. In accordance with at least one embodiment, reauthorization is conditioned upon a first content sink entry currency status having not yet expired. In accordance with at least one embodiment, the intermediate device allows authentication of the first content sink by the first content source when no first content sink entry exists on the authorized content sink list or when the first content sink entry currency status has expired.

Abstract: A method and apparatus for providing a power supply for an amplifier is provided. The power conversion is achieved using synchronous rectifiers in a regulated half bridge power supply, taking the sum of the positive and negative rails as feedback, in order facilitate energy transfer between positive and negative output rails. This minimizes the effects of off side charging and rail sag, as well as achieving good line regulation, while allowing use of very small, low value output capacitors.
