  • WO 98/36395 A2 describes an arrangement for generating coded high-frequency signals in which a pyroelectric element for converting thermal process energy into electrical energy is used for generating the voltage. This electrical energy is converted into high-frequency energy by means of an element with a non-linear characteristic; such an element can be a spark gap or a semiconductor component. The high-frequency signal is then encoded using a coding device. Transducers and filters, e.g. SAW filter. Also described is the possibility of changing the arrangement depending on an environmental parameter, e.g. the ambient temperature.
  • the supply device has at least one pyroelectric voltage generator. Furthermore, there is at least a high-resistance threshold circuit and a voltage converter. The voltage converter is used to generate a substantially constant voltage suitable for the operation of the consumer from a briefly occurring discharge process of the pyroelectric voltage converter.

  • the voltage converter is connected to the voltage generator via the threshold circuit.
  • the control circuit is used to monitor the electrical voltage at the pyroelectric voltage generator with as little power as possible and to connect or disconnect the voltage transformers and any consumers connected to them when a threshold in terms of design or circuitry is reached. When this happens, the voltage generator discharges and the discharge current briefly drives the voltage converter.

It is preferably in good thermal contact with the source of temperature fluctuation to be used, e.g. B. a heating rib brought. A change in temperature .DELTA.T causes the separation of electrical charges in the pyromaterial, so that an electrical voltage builds up on the electrically conductive, typically metallized, end faces due to the low electrical capacity.
  • the pyroelectric voltage generator preferably comprises a monolithic pyroelectric single crystal, e.g. made of lithium tantalate, a pyroelectric ceramic or pyroelectric plastics, in particular in the present case as foils.

  • a transmission telegram generated in the sequence control is impressed on a transmission signal, for example a high-frequency signal, in a downstream transmitter and then sent.
