  • Patent number: 9674517
    Abstract: In a method and system for assessing video quality, an analog video signal to be assessed is input. At least part of the incoming video signal is converted to digital values. The digital values are stored. A detector determines whether any stored digital value is outside an acceptable range.

  • Publication number: 20110161042
    Abstract: Apparatus, systems and methods for determining relative spatial orientation of a first member and a second member connected by one or more hinges are provided. A first member having one or more first accelerometers disposed therein can provide a first signal proportionate to the acceleration of the first member along one or more axes. A second member having one or more second accelerometers disposed therein can provide a second signal proportionate to the acceleration of the second member along one or more axes. One or more hinges can pivotably connect the first and second members. A controller can receive the first signal provided by the one or more first accelerometers and the second signal provided by the one or more second accelerometers to calculate the spatial orientation of the first member with respect to the second member.

  • Patent number: 7043570
    Abstract: A computer system with dynamic device identification redirection. The computer system may include a processor, a system memory, and a bridge logic device having a peripheral bus interface. The bridge logic device is associated with at least a first address line, which is also associated with a first peripheral device. The computer system may also include a logic device coupled to the peripheral bus that swaps a second address line for the first address line when a peripheral bus cycle is run to the first address line.

  • Patent number: 6799237
    Abstract: The present invention comprises a system and method for insuring that a notebook computer and a docking station are compatible. This determination is made by each of the notebook and docking station communicating via a serial communication pathway. Each of these devices reads a product code and a ROM date associated with the other device, and then independently determine whether the other device may be safely communicated with or “docked.” The systems and methods also take into account that two devices may be docked, but that only minimum functionality can exist between them based on differences in software revisions. In this case, the systems and methods allow the two devices to dock, but the computer system user is notified of the differences in software revisions.

  • Publication number: 20040128571
    Abstract: A system and method are disclosed for handling devices that assert a wake-up signal in an improper fashion. It is observed that any wake-up signals that remain asserted as the computer system enters a low-power mode are likely produced by non-compliant cards, and to assure proper functioning of the system, it is desirable for the computer system to selectively block assertion of asserted signals from non-compliant cards. In one embodiment the computer system includes an expansion bus coupled to a bus bridge, and a signal gate. The expansion bus includes a wake-up signal that the signal gate can be configured to isolate from the bus bridge. The signal gate is preferably controlled by the power management controller. The power management controller sets the signal gate to isolate the signal from the bus bridge if the controller determines that wake-up signal is being driven in a non-standard manner.

  • Publication number: 20040059843
    Abstract: A computer system reroutes a configuration cycle intended for an unused system bus address line to the IDSEL, or equivalent, configuration chip select input pin of a device which uses the same system bus address line as another device on the system bus. The computer system has a PCI bus to which a programmable logic device and an electronically-controlled switch are connected. The programmable logic device detects PCI bus configuration cycles associated with a PCI bus AD line that is otherwise unused as a chip select during configuration cycles. When the logic device detects a configuration cycle associated with the unused AD line, the logic device asserts a control signal to the electronically-controlled switch. The switch then connects the previously unused AD line to the AD line that is connected to the IDSEL input pin of the PCI device that experiences the conflict.

  • Patent number: 6078112
    Abstract: Apparatus is provided for adapting a computer system having a standard half-height bay to operatively receive multi-purpose bay devices therein. In one described embodiment, an adapter is provided which may be conveniently mounted in a standard half-height bay, but which is configured to accept multi-purpose bay devices. The adapter includes standard drive connectors, and connectors which permit the adapter to be effectively used in systems having features such as circuitry permitting hot-swapping of drives and circuitry for controlling battery charging and/or discharging. The adapter also includes circuitry for automatic selection of a power source to supply power to devices installed therein.
