    摘要: A driving signal is applied to a plurality of driving electrodes using the driving matrix illustrated in FIG. 5A obtained by removing a row in which a sum of codes is greatest and a column having a transposition relationship with the row in a Hadamard matrix. Distribution of capacitance in intersection portions between a sensing electrode and a plurality of driving electrodes can be obtained using an inverse matrix of the driving matrix illustrated in FIG. 5B. Further, when decoding is performed using an extended matrix obtained by replacing “0” with “−1” in FIG. 5B, it is possible to average noise and to improve an S/N ratio.

    摘要: An opening/closing control device includes: a current detecting unit that detects a current that flows in a motor; a voltage detecting unit that detects a voltage to be supplied to the motor; a load calculating unit that calculates a load applied during the opening/closing operation of a window, according to the detected current and detected voltage; a trap detecting unit that detects a trap of an object, the trap being caused by the window, according to the calculated load; and a motor control unit that, if a trap is detected, reverses the rotation of the motor. The load calculating unit calculates a load in which a first load component proportional to the detected current and a second load component proportional to the angular acceleration of the rotation of the motor, the angular acceleration being approximated according to the detected current and detected voltage, are combined together.
