  • Patent number: 11009409
    Abstract: To improve the efficiency of pressure detection, a driver applies a positive-phase signal to a capacitance element from an opposite side to a coupling point in a control device. Another driver applies a reverse-phase signal to another capacitance element from an opposite side to the coupling point. A control unit detects pressures applied to the capacitance elements based on a potential fluctuation at the coupling point.

  • Patent number: 10015508
    Abstract: Before completion of merge encoding processing of an immediately preceding PU, a controller determines the order of evaluation of merge candidates with the immediately preceding PU excluded from the merge candidates to be evaluated, and a merge-candidate derivation part evaluates each merge candidate in the order of evaluation. After the completion of the merge encoding processing of the immediately preceding PU, the controller re-determines the order of evaluation of merge candidates with the immediately preceding PU included in the merge candidates to be evaluated, and the merge-candidate derivation part evaluates each merge candidate in the re-determined order of evaluation excluding the merge candidate whose evaluation has already been started.

  • Patent number: 8427802
    Abstract: An overvoltage protection circuit includes a PMOS transistor Q1 that is disposed between an input circuit 21, from which an input voltage VIN is supplied, and a system 22 and functions as a switch. A comparator 110 compares the input voltage VIN with a predetermined reference voltage to determine the occurrence of an overvoltage. Further, the comparator 110 outputs a High level as an operation signal when no overvoltage is detected. A soft switching control circuit 130 starts up by using the High level output from the comparator 110 as an enable signal, and gradually turns on the PMOS transistor Q1. A sudden change of the load exerted on the circuit on the input side is suppressed by the soft start function.
