Abstract
Abstract An improved electronic clinic apparatus includes a group of a number of probes positioned on or above at least one body surface of a person subjected to a clinic operation. It includes further a multichannel amplifier for amplifying electrical potential sensed at each of the probes. A multiplexer is connected with the amplifier at its output and an AD-amplifier is connected with the multiplexer at its output. An electronic computer for treatment of digital outputs from the AD-amplifier is provided. Various and several display units are provided for displaying outputs from the computer. Control means are provided between the multiplexer and the computer for successive read-out of the sensed potentials at the grouped probes and within a variable operating period, and for providing a pause period thereafter. The variable operating period added with the pause period defines a predetermined functional cycle period such as 2 ms. The subject apparatus removes improper probe signal(s) including inhibitingly large noise signals and replenishes properly calculated and established imaginary signals in place thereof. The removal and replenishing job is performed during said pause period.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
197 words
An electronic clinic apparatus, comprising in combination: a group of a number of probes positioned in proximity to at least one body surface of a person subjected to a clinic operation; a multichannel amplifier for amplifying electrical potential sensed at each of said probes and having an output; a multiplexer connected to said amplifier at said output of said amplifier, and having analog outputs; converter means connected to said multiplexer for converting said analog outputs of said multiplexer to corresponding digital outputs; computer means for processing said corresponding digital outputs of said converter means to produce outputs of said computer means; display means for displaying said outputs produced by said computer means; and control means provided between said multiplexer and said computer means for successively reading out the sensed potentials at the probes within a variable operating period and for providing a pause period thereafter, said variable operating period being added with said pause period to define a predetermined functional cycle period, said control means intentionally removing improper probe signals including excessively large noise signals and replenishing properly calculated and established imaginary signals in place thereof, said removal and replenishing functions being performed during said pause period.
Claim 2
Dependent Claim
