Abstract: The present invention relates to a sensing structure of touch panel, which comprises a plurality of electrode groups disposed on a substrate. The substrate has a first side and a second side. Each electrode group comprises a first external electrode, a second external electrode, a plurality of internal electrodes, and a plurality of wires. The first external electrode is disposed on a first side; the second external electrode is disposed on the second side; the plurality of internal electrodes are disposed between the first external electrode and the second external electrode; and the plurality of wires are disposed on both sides of the electrode group alternately. Thereby, by disposing the first external electrode, the second external electrode, and the internal electrodes, all being zigzag, the disposable number of electrodes in each electrode group is increased. Accordingly, the sensitivity of touch sensing for the sensing structure of touch panel is enhanced.

Abstract: The present invention discloses a mobile phone comprising a gravity sensor, a processor, and a memory. The gravity sensor senses inertia data along a specific direction, the processor couples with the gravity sensor and receives a output signal from the gravity sensor, and the memory stores at least one personal information and operates under the processor's control. When either the gravity sensor or the processor detects a vertical free-fall motion, the processor performs a information security process to lock the personal information to become inaccessible.

Abstract: The present invention relates to an operational amplifier having low power consumption, which comprises a differential circuit, an output-stage circuit, and a floating bias generating circuit. The differential circuit receives an input signal and produces a control signal. The output-stage circuit is coupled to the differential circuit and produces an output signal according to the control signal. The floating bias generating circuit is coupled between the differential circuit and the output-stage circuit and generates a floating bias according to the control signal for controlling the rising or lowering of the voltage level of the output signal. Accordingly, the operational amplifier can charge and discharge rapidly, and thus extending the applications of the operational amplifier. Besides, the floating bias generating circuit can limit the output current while the operational amplifier is driving, and thus achieving the purpose of low power consumption.
