RADIO-FREQUENCY SIGNALLING CHANNEL UNIT (VERSIONS) AND RECEIVING AND TRANSMITTING CIRCUITS OF IMPLANTED ELECTRONIC SYSTEM Russian patent published in 2013 - IPC A61N1/36 H04B5/00 

FIELD: medicine.

SUBSTANCE: invention refers to medical equipment, namely wireless devices transmitting data to implanted systems. A signalling channel device comprises an amplitude modulation unit of RF pulse data transfer, a receiving circuit and a transmitting circuit with the transmitting unit having the 'RF on' state and the 'RF off' state and comprising a unit for decreasing the quality of the transmitting resonant circuit on interval of time corresponding to the 'RF off' state and the 'RF on' state for acceleration of the RF amplitude decay in the receiving circuit on the interval of time corresponding to the 'RF off' state. According to the second implementation, a device comprises the amplitude modulation unit of RF pulse data transfer and a unit for providing RF wave form decay independence on a coupling ratio. The transmitting circuit of the implanted electronic system comprises an external transmitting circuit for data transfer onto the implanted receiver by RF pulse amplitude modulation.

EFFECT: use of the invention enables minimising the channel switch time upon completion of each data pulse.
