  • Patent number: 6600739
    Abstract: A switching device and method for selecting among a plurality of hosts on a bus, such as a Universal Serial Bus (USB). The switching device includes a first hub to be coupled to first host controller and a second hub to be coupled to second host controller. A first selection device is to be coupled to a first peripheral device and the first and second hub devices. The first selection device is to selectively couple the first peripheral device to one of the first and second host devices in response to a selection signal. A second selection device is to be coupled to a second peripheral device and the first and second hub devices. The second selection device is to selectively couple the second peripheral device to one of the first and second host controllers in response to the selection signal. The selection signal is generated in response to one of the host controllers.

  • Patent number: 6253250
    Abstract: A bus bridge coupled between two bridges providing bus exception event isolation and address/data translation. In one embodiment the bus bridge includes two direct memory access (DMA) engines and a first-in-first-out (FIFO) buffer interface between the DMA engines to provide the bus exception isolation. The DMA engines and FIFOs also enable a packet based message passing architecture, which eliminates the need for address translation and also handles data reordering.

  • Patent number: 5812202
    Abstract: A method and an apparatus perform an inverse telecine procedure on a video sequence to eliminate redundant information introduced by the telecine process, so as to achieve more efficient data compression. The method and apparatus maintain synchronization between audio and video portions of the video sequence by ensuring that 20% of all frames, distributed substantially uniformly over the video sequence, are deleted. One embodiment of the present invention is provided in desktop computer system.

  • Patent number: 4548425
    Abstract: A motor vehicle occupant restraint belt system has a slide loop pivotally mounted on the pillar and dividing the belt into a retractable portion extending vertically along the pillar to a retractor and a restraint portion movable between an occupant restraining position extending across the occupant and a stored position extending along the pillar. A molded plastic sheath is pivotally mounted in conjunction with the slide loop and has a tubular sleeve which encloses a segment of the restraint portion of the belt. A retainer clip is provided on the pillar below the slide loop and retains the sheath in a stored position retaining the restraint portion of the belt stored against the pillar. The tubular sleeve has a reverse flange extending along the length thereof and adapted to capture the retractable portion of the belt when the sheath is stored against the pillar to prevent flapping in the airflow admitted through the door window.
