摘要： An exemplary electronic device capable of automatically selecting a power source includes two power ports configured to connect to external power sources and a battery compartment configured to receive a battery module. The voltage of the battery module is higher than at least one of the external power sources. The electronic device further includes a power selection module allocated between the battery module and the power port which selects the lower voltage. Three diodes are respectively located on the output path of the three power sources. A path switch that controls whether power to the device comes from the battery compartment or a power port is located between the anode of the battery compartment and the diode located on the output path of the battery module. Among the multiple power sources, the external power source providing a higher voltage is the first to be chosen to power the electronic device.

摘要： A touch sensing apparatus is provided. The apparatus includes a flip-flop (15), a sensor (13), an AC signal (14), and a detector (16). The AC signal supplies AC signals to the flip-flop. The flip-flop outputs a first output signal at the output of flip-flop when the sensor is not touched. The sensor receives electricity signals from the object, and causes a delay of the AC signal inputted to the first input of the flip-flop, the delay of the AC signal to be inputted to the first input of the flip-flop further causes the flip-flop to output a second output signal at the output of the flip-flop. The detector detects a change from the first output signal to the second output signal at the output of the flip-flop and accordingly identifies a touch on the sensor.

The sensor is for receiving electricity signals from an object that touches the sensor. The MCU (Microcontrol Unit) has a signal output port A and a signal input port B. The signal input port is connected to the sensor. The integration circuit interposes between the signal output port and the signal input port of the MCU. The signal output port outputs AC signals to the signal input port through the integration circuit. The integration circuit prolongs active transition times of the AC signals, and the MCU identifies a touch on the sensor when the active transition times of the AC signals fall in a predetermined range and accordingly implements a predetermined function.
