Abstract
Abstract In order to telemeter data from a moving body to a fixed recorder, a unidirectional voltage representing the data is converted by means of circuitry to frequency modulated pulses which are fed to a transmitting coil which sets up an induction magnetic field; the circuitry and the coil are both mounted on the moving body. A fixed recording system includes a receiver having an antenna located in the induction field of the transmitting coil. The receiver converts the pulses picked up to a unidirectional voltage which provides the input for the recorder.
