Abstract

PURPOSE:To eliminate or reduce a power supply and an oscillating element, by providing the fields of a high-frequency electromagnetic field, magnetic field, ultrasonic wave, etc. for the oscillating energy in a space and then absorbing this oscillating energy. CONSTITUTION:The energy is received by a wave receiver 9 from a field 8 of oscillting energy formed in a space and then rectified by a rectifying circuit 10 to drive a frequency dividing or multiplying circuit 11, a code data producing circuit 3 and a modulating circuit 12. At the same time, a carrier wave is obtained directly from the AC component of the field 8 of the oscillating energy received by the receiver 9 or after division or multiplication performed through the circuit 11. This carrier wave is applied to a modulating circuit 12. Then a clock signal obtained in the same way is applied to a code data producing circuit 3 such as a microcomputer, etc. The output data of the circuit 3 is applied to the circuit 12 to give modulation to the carrier wave. This modulated carrier wave is transmitted to the outside through a coupler 13 like an antenna, etc.

In addition, carrier waves and clock signals are generated by directly or by multiplying or dividing the alternating current component of the field, thereby eliminating or reducing the need for an oscillation circuit and oscillation elements.

If a crystal oscillator is used as the oscillation element of the generator, the frequency accuracy and stability of the transmission and clock signals will be extremely high. Furthermore, since the alternating current component of the field (8) and the output data are synchronized in a specific relationship, it is also easier to decode the data at the receiving end of the modulated carrier wave.
