Claim 1
Independent Claim
118 words
IN COMBINATION: A PLURALITY OF ELECTRICAL PROBES EACH ADAPTED FOR SENSING PHYSIOLOGICAL SIGNALS OF A DIFFERENT NATURE; AN AMPLIFIER HAVING ITS INPUT COUPLED TO SAID PROBES FOR PRODUCING OUTPUT SIGNALS WHICH ARE AMPLIFIED SUBSTANTIAL REPRODUCTIONS OF SAID SENSED PHYSIOLOGICAL SIGNALS; A D.-C. VOLTAGE DIVIDER NETWORK FOR PROVIDING A PLURALITY OF D.-C. ELECTRICAL REFERENCE CODING SIGNALS; A SIGNAL OUTPUT LINE FOR TRANSMITTING ELECTRICAL SIGNALS TO A UTILIZATION DEVICE; AND MEANS FOR SELECTIVELY SWITCHING SAID SIGNAL OUTPUT LINE TO THE OUTPUT OF SAID AMPLIFIER OR RESPECTIVELY DIFFERENT ONES OF SAID VOLTAGE DIVIDER CODING SIGNALS WHEREBY EACH OF THE RESPECTIVE PHYSIOLOGICAL SIGNALS APPEARING ON SAID SIGNAL OUTPUT LINE IS SUITABLY IDENTIFIED BY ASSOCIATED D.-C. ELECTRICAL CODING SIGNALS ON SAID OUTPUT LINE.
