    摘要： A touch sensing system comprising: a frame work; an auxiliary layer, surrounding the frame work; a capacitive touch sensor layer, surrounding the auxiliary layer; a flexible material layer, located between the capacitive touch sensor layer and the auxiliary layer, and surrounding the auxiliary layer; and a flattening material layer, located between the capacitive touch sensor layer and the flexible material layer or located between the auxiliary layer and the flexible material layer, wherein the flattening material layer flattens the flexible material layer. The capacitive touch sensor layer comprises at least one first driving electrode and at least one first sensing electrode. The auxiliary layer comprises at least one electrode. Similar structure can also be used to a multi-sensor device and a vehicle control device. By this way, the assembling or the manufacturing can be simplified.

    摘要： An apparatus is provided and includes a rotary encoder that comprises a stator, a rotor, and a controller. The stator has an opening adapted to surround a first portion of a rotatable shaft, a transmit region, and a receive region. The rotor has an opening adapted to surround a second portion of the rotatable shaft, an annular conductive region, and at least one conductor electrically coupled with the annular conductive region. The controller has an input coupled to the receive region and has an output coupled to the transmit region. The controller is configured to transmit a first signal on the output of the controller and to the transmit region of the stator, receive a second signal on the input of the controller and from the receive region of the stator, and determine, based on the second signal, a proximity of the at least one conductor to the receive region.

    摘要： A proximity sensor includes a conductor, a receiving electrode, and a first transmission electrode. The conductor has an upper surface. The receiving electrode is separate from the upper surface of the conductor in an upward direction and extends along a first direction. The first direction is orthogonal to the upward direction. The first transmission electrode is separate from the upper surface of the conductor in the upward direction and extends along the first direction. The first transmission electrode and the receiving electrode are aligned with each other in a second direction. The second direction is orthogonal to both the upward direction and the first direction. The first transmission electrode has an upper surface having a shape bulging in the upward direction in a cross section orthogonal to the first direction.

    摘要： The present invention is directed to a CV conversion amplifier which is small in current consumption and capable of securing a sufficient capacitance-voltage conversion gain and a sufficient amplitude range of an output voltage and a capacitive sensor using the same which is low power consumption, low in noise, and wide in an input signal allowable range. A capacitive sensor includes first and second detection capacitors, a CV conversion circuit includes first and second feedback capacitors and obtains a voltage based on capacitance values of the first and second feedback capacitors, an AD converter performs analog digital conversion on an input voltage and obtains a digital signal, a digital control unit receives the digital signal as an input, and first and second digitally controlled variable capacitors have capacitance values that are controlled by the digital control unit.

    摘要： The seat heater control device is provided for a vehicle including a vehicle body, a vehicle seat and a seat heater. The seat heater control device includes: an electrostatic sensor provided in the vehicle seat and configured to measure capacitance between the electrostatic sensor and the vehicle body; and a controller configured to control an operation and/or an operational temperature of the seat heater, based on a measured value of the electrostatic sensor. The controller is configured to cause the seat heater to operate at a relative higher temperature when the measured value of the electrostatic sensor is higher than a first threshold and lower than a second threshold. The controller is configured to cause the seat heater to operate at a relative lower temperature when the measured value of the electrostatic sensor is higher than the second threshold.
