  • Patent number: 9910691
    Abstract: Provided is a virtual interface, a “Forwarder” and a Virtual Block Storage Device (VBSD). The virtual interlace is the interface between a Command/Response Queue (CRQ), which receives CRQ commands from a hypervisor, and a common interface of the Forwarder. The Forwarder receives I/O commands in a format associated with the common interface and converts the commands into a generic I/O format. The reformatted command is transmitted to the VBSD. The hypervisor sends a read or write (R/W) request to the virtual interface, which passes the request to the Forwarder. The Forwarder receives the request, converts the request into a form readable by the VBSD and transmits the converted request to the VBSD. The VBSD transmits the request to a block storage device and returns the response to the Forwarder. The Forwarder replies to the request from the virtual interface with the response from the ABSD. The virtual interface then responds to the hypervisor.

  • Patent number: 9092288
    Abstract: When a power supply is cut off on updating programs, improper data remains since the power source to be supplied to the vehicle-mounted device is unstable. The check for the improper data and restoration processing are required for a reactivation processing implemented by an update processing unit so that the update is completed correctly, therefore, the user is waited. In contrast, the update processing also implemented by the update processing unit for a time period during which the power source becomes unstable is interrupted, and implemented for the time period during which the power source voltage is stable. The power source voltage is considered to be unstable based on a function of the vehicle speed, brake pedal actuation, parking brake actuation, and/or power source activation. In consequence, the update processing is carried on steadily without making the user wait.

  • Patent number: 8928698
    Abstract: Road information is compressed for map tiles of a map containing a network of roads. The map can have different sets of tiles for each zoom level. For a given zoom level, road segments can be grouped based on the class of the roads (e.g., interstate highway, state highway, divided highway, side street, etc.). The road segments of a particular class can be combined into paths, and a representative segment can be chosen for each path. The features of the representative segment can be used in displaying the corresponding path, thereby reducing the size used to store the path in a map tile. This reduce-size map tile can be transmitted more efficiently due to the smaller size.

  • Patent number: 8886857
    Abstract: Multiple devices are provided access to a common, single instance of data and may use it without consuming resources beyond what would be required if only one device were using that data in a traditional configuration. In order to retain the device-specific differences, they are kept separate, but their relationship to the common data is maintained. All of this is done in a fashion that allows a given device to perceive and use its data as though it was its own separately accessible data.

  • Patent number: 8810560
    Abstract: Methods and apparatus for enhanced synchronization of a descrambler, such as used in a signal interface that carries scrambled data. In one embodiment, the descrambler self-synchronizes to a scrambled bit stream (rather than receiving an external “sync” trigger), thereby allowing for much more rapid synchronization. This is accomplished in one variant by identifying a scrambled symbol that has an expected value, predicting an internal scrambler seed based on the expected value, and verifying the predicted seed. For example, an invention-enabled device can synchronize to a DisplayPort stream during blanking intervals which are filled with known “dummy” bytes. Blanking intervals are much more frequent than explicit synchronization symbols, thus an invention enabled device can greatly improve synchronization times, and eliminate e.g., visual artifacts.
