During the transmission of sensor data of an implantable sensor with a measurement data recorder, an energy storage unit and a transmitter unit to an external data processing unit with a transmitter/receiver unit, a high-frequency energy carrier signal is firstly emitted from an energy supply unit. At least a part of the energy contained in the high-frequency energy carrier signal is stored in the energy storage unit of the implantable sensor. After the ending of the emission of the high-frequency energy carrier signal, a sensor measurement is carried out using the measurement data recorder of the implantable sensor. The measured sensor data are transmitted from the transmitter unit of the implantable sensor to the transmitter/receiver unit of the external data processing unit. The result is a transmission method, in which interference from the HF feed is avoided, with a compact design.

The invention relates to a touchscreen-sensitive and transponder reading stylus. The object of the invention is to provide a small touchscreen-sensitive stylus whose power requirements are low and which allows transponder communication. The inventive stylus is characterized in that a hand-piece also accommodates an RF-ID electronic system and that it comprises a tip range that tapers in at least one direction of its scanning tip. Said tip area is provided with an antenna preferably in the form of an electric coil and is configured in such a manner that it is devoid of an electromagnetic screening, that an electromagnetic field emitted at the tapered end is substantially not attenuated and that it is suitable for the optically exact scanning of screens.

A transponder unit which can be integrated in a transport unit or a card or the like. The transponder unit includes, in addition to an encapsulated transponder of an integrated circuit, an aerial winding having a resistance Rand a capacitor parallel thereto and having a capacitance C. A closed coupling circuit of secondary winding is coupled with the aerial winding by a mutual inductance Mand a substantially larger primary winding in series with the secondary winding and having fewer turns, for example only one turn. To achieve almost optimum energy transfer between a reading device and the transponder and to increase the permissible reading distance, the mutual inductance Mis adjusted to comply with the relationship M=&#x221a;{square root over ( )}[R/&#x3c9;) (L+L+2M)], where &#x3c9;=1/(LC) is true for the receiving frequency &#x3c9; of the transponder and Land Lare the inductances of the primary winding and of the secondary winding and Mis their mutual inductance.
