Cordless pressure-sensitivity and electromagnetic-induction system with specific frequency producer and two-way transmission gate control circuit

摘要

The system with cordless pressure-sensitivity and electromagnetic-induction of the present invention comprises the first wireless apparatus and the second wireless apparatus. The first wireless apparatus comprises the first sub-circuit for emitting and receiving an electromagnetic wave with a specific frequency, and the second wireless apparatus comprises the second sub-circuit for emitting and receiving an electromagnetic wave with a specific frequency. The first sub-circuit comprises: an inductance coil, a rectifier that is coupled with the inductance coil and a charge sub-circuit. The second sub-circuit comprises: a sub-circuit for generating a specific frequency that is coupled with the control sub-circuit and a two-way gate control sub-circuit.
