ELECTROMEDICAL IMPLANT
First Claim
1. An implantable medical device (20) comprising:
- a transceiver (203) configured to transmit and receive wirelessly transmitted data, which is turned off or switched into an energy-saving rest state between individual data transmissions via said transceiver (203) wherein said transceiver comprisesa waking unit (202), which is implemented to switch said transceiver (203) from its turned-off state or its rest state into its fully operational state by a waking signal;
wherein said waking unit comprises a low-power receiver (210) and a waking control unit (206), of which said low-power receiver (210) is implemented to monitor multiple predefined frequency ranges in such a way that, in case of a transmission of sufficient signal strength in one or more frequency ranges, wherein said low-power receiver (210) generates an output signal and outputs said output signal to said waking control unit (206), and of which said waking control unit (206) is implemented to analyze output signals of said low-power receiver (210) and to output said waking signal to said transceiver (203), which switches said transceiver (203) on or to fully operational, if a predefined condition is met or multiple predefined conditions are met;
wherein said waking control unit (206) is implemented to output said waking signal to said transceiver (203) if a condition is met that said low-power receiver (210) outputs a sequence of output signals which identify that said low-power receiver (210) has detected a series of (data) transmissions of sufficient signal strength in various frequency ranges which correspond to a predefined series/sequence (of frequencies).

Abstract
An implantable medical device having a transceiver for transmitting/receiving wirelessly transmitted data, which is turned off or switched into an energy-saving rest state between individual data transmissions via the transceiver and having a waking unit which is implemented to switch the transceiver by a waking signal from its turned-off state or its rest state into its fully operational state, the waking unit having a low-power receiver and a waking control unit of which the low-power receiver is implemented to monitor multiple predefined frequency ranges in such a way that in case of a transmission of sufficient signal strength in one of the frequency ranges, it generates an output signal and outputs it to the waking control unit and of which the waking control unit is implemented to analyze output signals of the low-power receiver and output a waking signal to the transceiver which switches it on or to fully operational.
