Abstract: An audio-on-demand communication system provides real-time playback of audio data transferred via telephone lines or other communication links. One or more audio servers include memory banks which store compressed audio data. At the request of a user at a subscriber PC, an audio server transmits the compressed audio data over the communication link to the subscriber PC. The subscriber PC receives and decompresses the transmitted audio data in less than real-time using only the processing power of the CPU within the subscriber PC. According to one aspect of the present invention, high quality audio data compressed according to lossless compression techniques is transmitted together with normal quality audio data. According to another aspect of the present invention, metadata, or extra data, such as text, captions, still images, etc., is transmitted with audio data and is simultaneously displayed with corresponding audio data.

The magnet assembly is adapted to rotate relative to the conductor assembly about an axis so as to induce eddy currents in the conductor assembly when relative motion is produced between the conductor assembly and first magnet assembly. The conductor assembly is adapted to translate transversely into and out of magnetic engagement with the magnet assembly. In one embodiment, the conductor assembly defines a fluid path therein for the transfer of heat from the conductor assembly to a fluid. The magnetic heater is a component of a heat generation system comprising an internal combustion engine having a drive shaft for rotating the magnet assembly. The heat generated by the magnetic heater, as well as the heat generated by the engine from the engine exhaust and engine cooling system, is combined to heat a fluid.

In another embodiment, the eyelets are substantially the same size, substantially equally spaced and substantially collinear. In another embodiment, the eyelets are in a staggered arrangement. In another embodiment, the plunger first end comprises a retention portion adapted to couple with a suitable coupler adapted to retain the plunger first end within a bore of a solenoid.
Abstract: An API including an interrupt handler registration function and one or more interrupt dispatchers, is provided to an optical networking apparatus to facilitate registration of interrupt handlers to handle interrupts triggered by the function blocks of multi-protocol optical networking modules (MPONM). Each registered interrupt handler may handle interrupts triggered by one or more function blocks of any of the MPONM, and/or for one or more cause. In one embodiment, the one or more interrupt dispatchers are equipped to determine the triggering function block and the cause, and determine the interrupt handlers, if any, are to be notified. Each of the interrupt handlers to be notified is notified accordingly, including the triggering function block and the cause.
Abstract: A cancellation circuit to remove the anti-resonance signal from a resonator. Micro-mechanical and surface and bulk acoustic wave resonators include an anti-resonance in an output signal. This has an undesirable effect on certain types of systems in their function and performance. An anti-resonance cancellation circuit removes the anti-resonance from the output of the resonators by providing a signal which is subtracted from the output of the resonator. The cancellation circuit includes a capacitor which is matched to the static capacitance of the resonator. The loads of the resonator and cancellation network are also matched.

Abstract: In accordance with embodiments of the present invention, a system is provided comprising an oxygen-enrichment reverse osmosis unit coupled to an intake of an internal combustion engine. Ambient air is supplied to the reverse osmosis unit via an ambient-air inlet and oxygen-enriched air is output via an oxygen-enriched outlet. The oxygen-enriched outlet is coupled to the intake of a combustion chamber of the internal combustion engine. Providing oxygen-enriched air relative to ambient air to the internal combustion engine allows for reducing the size of the combustion chamber while providing equivalent power, resulting in a smaller engine. At the same time, the smaller engine saves consumption of fuel due to lower engine weight and more complete combustion. The smaller engine is also cheaper to build because it requires less material for fabrication.

Abstract: An illuminated keyed remote control device providing illumination in the visible spectrum and the functionality of a wireless signal transmitter. Light projects from one or more translucent portions of the remote control device, at least a portion of which illuminates the key. The illuminated remote control device comprises at least one translucent portion adapted for the transmission of light from a cavity to the outer surface of the housing. At least one control feature is provided to operate transmitter electronics and/or the light source housed in the cavity. The light source produces light within the cavity, the light being then guided from the cavity to the surface by a translucent portion of the housing. The illumination provides the user with an increased ability to see or be seen in the dark and provides illumination that is visually appealing.

Abstract: An API is provided to an optical networking apparatus to facilitate uniform access, control or interaction with its multi-protocol optical networking modules (MPONM) by its applications. Each of the MPONM has a number of function blocks having corresponding service routines. In response to an application's request to initialize a MPONM, the initialization function of the API cooperates with the function block service routines to create a data structure for the MPONM, and returns a handle of the data structure to the application. Thereafter, in response to a need to have an operation performed in a function block of a MPONM, the application makes the request with an externalized function the API associated with the function block, including with the request the handle of the data structure of the MPONM.
