1Reliability
If conventional remote control techniques (infrared, radio, Bluetooth) are used with pairing and decoding schemes, then reliable device control is achieved, but circuit complexity increases significantly
Solution Approach 1:
The patent extracts and eliminates the complex decoding and demodulation functions from the receiver circuit. By using a counter unit that directly responds to initiation signals without requiring pairing or decoding, the circuit achieves reliable control with significantly reduced complexity. The counter unit sequentially activates output terminals based on simple signal reception, removing the need for programmed control units and decoding schemes.
Solution Approach 2:
The driver circuit is designed to be universally compatible with any remote control unit without requiring specific pairing. The counter unit responds to initiation signals from any transmitter, making the system multi-functional and adaptable to different remote controls while maintaining simple circuit architecture.
2Reliability
If pairing between transmitter and receiver is implemented, then controlled device responds only to paired transmitter, but operation convenience deteriorates
Solution Approach 1:
The receiver module with counter unit is designed to respond to initiation signals from any remote control transmitter without requiring pairing. This universal compatibility allows any remote control unit to operate the electrical device, significantly improving ease of operation while maintaining reliable signal response through the counter's sequential activation mechanism.
3Measurement precision
If decoding and demodulation functions are added to the receiver, then accurate signal interpretation is achieved, but circuit architecture becomes complicated
Solution Approach 1:
The patent removes the decoding and demodulation functions from the receiver circuit architecture. The counter unit directly interprets initiation signals without requiring programmed control units or decoding schemes, achieving accurate signal response through simple sequential activation of output terminals based on the counting sequence.
4Device complexity
If a simple circuit architecture is used without decoding functions, then circuit complexity is reduced, but control precision over electrical device operation deteriorates
Solution Approach 1:
The counter unit automatically generates the control signal sequence through its inherent counting function. Upon receiving an initiation signal, the counter sequentially activates its output terminals in a predetermined sequence, self-generating the control signals needed to drive the electrical device through different operation states without requiring external decoding or control programming.

AI summary
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.
