摘要： The invention realizes certainly detecting two or more positions on a touch panel that are touched at the same time. A drive circuit selects one from X lines, and supplies an alternating drive voltage to the selected line. A multiplexer selects a first sense line and a second sense line from Y lines that extend to cross the X lines. A charge amplifier outputs an output voltage corresponding to a difference between a first capacitance between the first sense line and the X line selected by the drive circuit and a second capacitance between the second sense line and the X line selected by the drive circuit. A touch position is then detected based on the output voltage of the charge amplifier.

摘要： There is offered a signal processing circuit for an electrostatic capacity type touch sensor capable of detecting a larger number of locations with a smaller number of touch pads as well as improving noise immunity. A selection circuit selects either a signal from a combination of the first and second kinds of touch pads outputted through the first and second output terminals CO1 and CO2 in a touch panel or a signal from a combination of the third and fourth kinds of touch pads outputted through the third and fourth output terminals CO3 and CO4. An electric charge amplifier outputs first and second output voltages V1 and V2 corresponding to a difference between capacitances of the touch pads on the touch panel based on the signals from the selected combination. A delta sigma type A/D converter converts the first and second output voltages V1 and V2 into digital signals.

摘要： In some preferred embodiments, in an authentication system including a plurality of portable devices and a base station, if the portable device is operated by an internal battery, ID data encrypted at a higher level are exchanged (normal mode), and if the portable device is operated by electromagnetic induction coupling with the base station, ID data encrypted at a lower level are exchanged (backup mode). These two communication modes are performed in the same communication device. The portable device transmits a signal showing a state of the battery voltage to the base station, and the portable device and the base station store the battery state in the respective storing portions. At the time of initiating communication, the portable device transmits a signal in the normal mode as first communication. If there is no response from the portable device, the portable device refers to the storing portion, and only if there is a portable device insufficient in voltage, the base station shifts communication in the backup mode.
