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: Multiple sensor electrodes are formed such that they overlap a display panel, and each have an electrostatic capacitance that changes according to the user's touch. Furthermore, a proximity sensor electrode pair is formed as a transparent electrode such that they overlap the display panel. An electrostatic capacitance detection circuit detects change in the electrostatic capacitance of each sensor electrode due to the user's touch, thereby detecting a position touched by the user. A proximity detection circuit detects change in the electric field generated between the proximity sensor electrode pair due to the proximity of the user, thereby detecting the proximity of the user to the display panel. An electrostatic capacitance detection circuit is configured to have at least a component that is switchable between an operating state and a non-operating state. When detecting that the user is in proximity, this component transits from the non-operating state to the operating state.

Abstract: A situation in which effect processing such as position adjustment of a virtual sound source located in a sound field does not synchronously match the timing of reproducing a sound is suppressed. With a sound source circuit 100, a FIFO memory stores the information that indicates a change in a virtual sound source located in a reproduced sound field and audio data. A control unit operates in cooperation with a 3D positioning unit which performs position adjustment processing for the audio data stored in the FIFO memory so as to adjust the position of the virtual sound source located in the reproduced sound field. With such an arrangement, a sound is reproduced according to the audio data subjected to the position adjustment. Upon detection of the aforementioned information, the control unit notifies the 3D positioning unit of the detection. At this time, an interruption signal that corresponds to the information may be transmitted to the 3D positioning unit via a dedicated signal line.

Abstract: A core unit implements a predetermined function. An I/O unit controls input from and output to the outside. The core unit and the I/O unit are subject to independent control for supply of power. When power is turned off in the core unit, a signal output from the I/O unit to the core unit is fixed at a low level, while power is maintained in the I/O unit. A first level shifter and a second level shifter are provided between the core unit and the I/O unit and cancel a difference in power supply voltage level between the units. Power is turned off in the first level shifter and the second level shifter when power is turned off in the core unit.
