摘要： A display device using a surface capacitive touch panel is proposed. Upon a normal mode, an external clock generator supports a clock source; meanwhile, an external clock generator, a signal generator, a current detector, a current-to-voltage converter, an analog-to-digital converter, a filter, an interface controller, a microprocessor, and the touch-position calculators are turned on. But under a power-down mode, the external clock generator, the analog-to-digital converter, filter, the interface controller, the microprocessor, and the touch-position calculators are turned off in order to reduce power consumption. Furthermore, the external clock generator is also turned off to minimize the power consumption.

摘要： A hand-held scanning system and method thereof are described. A look-up table is created to generate a mapping relation between a plurality of reference amplitudes and a plurality of corresponding sampled positions. An analog-to-digital converter samples an analog signal and converts it into a digital signal. The digital signal represents a mapping relation between the sampled positions of the movement distance and the corresponding scanning amplitudes of the signal intensity. The hand-held scanning system ascertains the sampled positions corresponding to a former scanning amplitudes and a present scanning amplitudes according to the look-up table during the scanning stage for detecting the position variation status to determine whether the trigger signal is activated for image scanning or not.

摘要： A scanning apparatus having dual power mode is described. The scanning apparatus includes a detection module, a switch unit, and a power controller. The detection module detects a first voltage signal and a second voltage signal for generating a detecting signal. The switch unit receives the commands from the power controller for outputting the first voltage signal and/or the second voltage signal to the image acquiring device of the scanning apparatus. The power controller determines whether the first voltage signal is detected according to the detecting signal. While the first voltage signal is detected, the power controller controls the switch unit to output the first voltage signal and/or the second voltage signal to the image acquiring device. While the first voltage signal is not exist, the power controller controls the switch unit to output the second voltage signal to the image acquiring device.

The scanning controller includes an image data processing unit, a memory control unit, a dummy line control unit, a buffer condition control unit, a motor condition control unit, a motor controlling unit and a relation control unit.
