    Abstract: A sensor interface circuit includes a continuous-time capacitance-to-voltage (C/V) converter having C/V input and output ends, the C/V input end being configured for electrical connection with first and second sense nodes of a capacitive sensor. A filter circuit is electrically coupled to the C/V output ends. The filter circuit has first and second resistors at corresponding first and second filter input ends of the filter circuit, a capacitor connected between first and second filter output ends of the filter circuit, and a chopper circuit interposed between the first and second filter input ends and the first and second filter output ends. A buffer circuit is electrically coupled with the first and second filter output ends of the filter circuit. The filter circuit applies low pass filtering of sense signals from the capacitive sensor before sampling and demodulation operations to reduce high-frequency interference in the sense signals.

    Abstract: A flexible capacitive touch sensing device comprising a first, a second sensing region and a capacitance detection circuit. Each of the first, second sensing region comprises: flexible material; and electrodes, in or on the flexible material. Capacitance sensed by the capacitance detection circuit is used for detecting if an object causes capacitance variation to the first sensing region and the second sensing region. The first sensing region comprises a first side region with a first side which is adjacent to a second side of the second sensing region Shapes of the electrodes are changeable after provided on the flexible material. The electrodes are overlapped in normal directions of the first side region and the second side region. An angle which is not 0 degree exists between the electrodes which are overlapped. Such flexible capacitive touch sensing device can be applied to generate a HOD device with different sizes.

    Abstract: An electrode structure includes: a base material; a conductive fabric on a first surface of the base material; and one or more conductive wires on a second surface of the base material so as to be electrically insulated from the conductive fabric. The second surface is opposite to the first surface of the base material. The base material includes: a first area and a second area. The first area is fitted into a groove of the rim and the second area is placed in a part of a rim of a steering wheel other than the groove, when the base material is attached to the rim. The one or more conductive wires are arranged at a lower wiring density in the first area than in the second area.
