Abstract: A touch pad module includes: a touch pad, a sensor group, a touch pad controller IC and a touch pad controller IC (Integrated Circuit). The touch pad has a touch surface touchable by a user. The sensor group is mounted on a mount surface of the touch pad. The sensor group includes at least one of an acceleration sensor, a gyro sensor and a geomagnetic sensor. The touch pad controller IC is mounted on the mount surface of the touch pad configured to control the touch pad and includes a detector, a digital processor and a first interface. The detector generates digital data representing an electrical state of the touch pad. The digital processor generates coordinate data representing coordinates touched by the user based on the digital data. The first interface transmits data between the digital processor and the outside of the touch pad controller IC.

Abstract: A first electrode is provided to a side wall of a container, and has a width that increases according to an increase in the depth. A second electrode is provided to the side wall of the container, and has a width that reduces according to an increase in the depth. A capacitance sensor measures a first electrostatic capacitance Cs formed by the first electrode and a second electrostatic capacitance Cs formed by the second electrode. A calculation processing unit generates water level data S2 that represents the water level, based on the measurement values S1 that represent the respective first and second capacitances Cs.
