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: 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.

Abstract: The present invention relates to a driver system, comprising a counter unit, a buffer unit and a voltage regulation unit. The counter unit is adapted to sequentially activate one of the first output terminals upon receiving a driver signal and then output a control signal according to the driver signal. The buffer unit is adapted to output an isolated control signal upon receiving the control signal from the counter unit. Upon receiving the isolated control signal, the voltage regulation unit outputs a control voltage which corresponds to a given resistor provided therein. The control voltage is useful in driving an electronic device, and the operation of the electronic device may be further adjusted by changing the control voltage from one level to another.
