Autonomous system for measuring, processing and transmitting essentially physiological parameters
First Claim
1. A system for measuring and displaying at least one physiological parameter by means of at least one sensor worn by an individual and providing signals representative of said parameter, said system comprising:
- on the one hand an autonomous processing apparatus which is attached to said sensor and provided with a plurality of means for measuring, for storing, for identifying and for binary coding said signals, said binary coding means being arranged so as to generate pulse trains of binary sequences of radio signals at terminals of a transmitting coil for transmitting the radio signals, one of said sequences constituting an address enabling a transmitting processing device to be identified, others of said sequences being representative of data constituted by a measurement and its result; and
, on the other hand, a separate display device connected to the processing apparatus by wireless communicating means, said separate display device comprising a radio signal-receiving coil, signal amplifying and shaping means at terminals of said receiving coil, and means for decoding the signals, characterized in that the decoding means comprises a sequence generator arranged so as to open detecting windows synchronous with the pulse trains transmitted by the processing device, and to restore the binary sequence representative of the transmitted data as a function of distribution of said pulses in said detecting windows, in that the signal amplifying means at the terminals of the receiving coil are set into operation only during occurrence of said detecting windows, so as to reduce energy consumption, and in that the data transmitted by said processing device are restored and displayed only if a determined address had previously been identified.

Abstract
The invention concerns a system for measuring and displaying physiological parameters. It comprises, on the one hand, a sensor or sensors and a measuring device attached to the body, and on the other hand, a separate display device, for example a digital watch attached to the wrist, receiving from the measuring device the parameters to be displayed in the form of digitalised radio signals. A first application example concerns the measurement of the ECG signal and the display of parameters relating to the heart. A second example concerns the measurement of blood sugar levels and the display of insulin doses to be injected, if required.
