  • Patent number: 8243002
    Abstract: In a display device, a first frame of input image signals is received by a signal controller, stored in a memory, and applied to rows of pixels while a gate driver scans a gate-on voltage to a gate line in a first mode to select a row of pixels, one row at a time. When a gate driver controller detects that a second frame of image signals is being received by the signal controller, the gate driver controller halts the operation of the gate driver until the second frame of input image signals has all been received by the signal controller and until a scan start signal is detected by the gate driver controller.

  • Patent number: 8244486
    Abstract: Storage of information, such as baseline information and structure ID, in a memory that is mounted on the structure, rather than inside the diagnosis hardware. This allows for faster and more convenient information retrieval. In particular, this approach allows for a more modular system in which different diagnosis hardware or other analyzers can be simply plugged into a structure's sensor network, whereupon they can quickly download any desired structure-specific information (e.g., baseline information, structure ID, and other useful information) from the on-structure memory.

  • Patent number: 8229680
    Abstract: Methods and apparatuses for detecting fastener loosening. Sensors query a structure at a baseline value of an environment variable, such as temperature, and this baseline signal is stored for later use. Subsequently, users can query the structure remotely and at any time, and the signals from these queries are compared to the stored baseline signal. In some embodiments, an index is calculated, and the system determines that one or more fasteners have come loose if the calculated index exceeds a predetermined threshold value. It is desirable to select a time window within which the query signal is most sensitive to fastener loosening but least sensitive to variations in the environment variable. Accordingly, embodiments of the invention include methods and apparatuses for determining an optimal time window for use in calculating the above described index.
