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： A conventional inverting amplifier has a problem that an oscillation may be induced depending on a structure of an internal amplifier. This invention offers an inverting amplifier having a multi-stage amplifier that is provided with a first transistor that amplifies an input signal, a second transistor that amplifies an output signal of the first transistor, a third transistor that amplifies an output signal of the second transistor and an internal feedback resistor that feeds back an output signal of the third transistor to an output node of the first transistor. With the structure described above, a required gain can be set without inducing oscillation, because a gain of the multi-stage amplifier composed of three-stage transistors can be reduced.

摘要： A power supply system for supplying a grid power to a building includes a power generator, a power storing device, and a power controller. The power generator generates off-grid power from a predetermined energy. The power storing device stores the grid power and the off-grid power and supplies the stored power to the building. The power controller controls consumptions of the grid power and the off-grid power. The power controller calculates predicted consumption data related to power consumed in the building and predicted generation data related to power generated by the power generator. The power controller calculates a charging-discharging schedule for the power storing device based on the predicted consumption data and the predicted generation data by formulating the charging-discharging schedule as a mixed integer programming problem.
