Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
115 words
AN ELECTRONIC UNIT WHICH COMPRISES A SOLID CONDUCTIVE BODY OF FINITE RESISTANCE HAVING A SURFACE OF SUBSTANTIAL AREA, AN ACTIVE ELECTRONIC ELEMENT ADAPTED TO CONTROL ELECTRIC CURRENT IN RESPONSE TO AN INPUT, A PAIR OF SPACED APART INPUT TERMINALS ON SAID SURFACE FOR CONNECTING SAID BODY TO A SOURCE OF POTENTIAL TO ESTABLISH AN ELECTRIC FIELD IN SAID BODY, CONNECTIONS FROM SAID ELEMENT TO POINTS HAVING AREAL SPACINGS ON SAID SURFACE FOR SHAPING RESISTANCE PATHS IN SAID BODY BY MODIFICATION OF SAID ELECTRIC FIELD UPON INTERCHANGE OF ELECTRIC QUANTITIES BETWEEN SAID ELEMENT AND SAID BODY BY WAY OF SAID CONNECTIONS, AND CIRCUIT MEANS EXTENDING TO SAID BODY FOR INTERCHANGE WITH SAID BODY OF UTILIZATION POTENTIALS.
