Abstract:
The driver system according to the invention includes an infrared receiver module and a Johnson counter. The infrared receiver module receives an infrared signal and performs filtering using a low-pass filter to convert the infrared signal into a driving signal which is transmitted to the Johnson counter. Upon receiving the driving signal, the output terminals of the Johnson counter are sequentially activated to output a control signal for shifting the operation of an electrical device from one operation state to another.
Abstract:
An EMP protection circuit with a counter has a surge protection circuit capable of suppressing EMP, and also use an extra counting circuit for sensing light emission or variation of magnetic force of the surge protection circuit to count the action times of the surge protection circuit, thereby warning that the surge protection circuit has reached its time-limit of use and has to be replaced. In this way, various kinds of electronic products can be more perfectly protected to avoid higher loss.

Abstract:
The method increases the output frame rate to p/q (p, q are both natural numbers and p>q) times of the input frame rate. In a period of time equal to the least common multiple of the input and output frame times, q input frames are output and (p−q) transient frames are generated and inserted at appropriate places before or after the q input frames in the output frame sequence so as to enhance the dynamic display effect of the display device.

Abstract:
The driver circuit according to the invention includes a receiver module, a counter unit, isolation units and a voltage regulation unit. The receiver module receives an initiation signal and performs filtering using a low-pass filter to convert the initiation signal into a driving signal which is transmitted to the counter unit. Upon receiving the driving signal, the output terminals of the counter unit are sequentially activated to output a control signal. The isolation units may be diodes or transistors adapted to output an isolated control signal. The voltage regulation unit includes a plurality of resistors and is adapted to output a control voltage corresponding to one of the resistors according to the isolated control signal. The control voltage is useful in shifting the operation of an electrical device from one operation state to another.
