Linearizing multi-channel digitizer

Claim 1

THE SYSTEM COMPRISING A ISGNAL SENSOR FOR PROVIDING A SENSOR SIGNAL WHICH VARIES NON-LINEARLY IN RESPECT TO THE FUNCTION BEING SENSED FROM A LOW REFERENCE VALUE TO A HIGH REFERENCE VALUE, A COMPARATOR CIRCUIT FOR PROVIDING A COMPARATOR SIGNAL, SAIDCIRCUIT INCLUDING MEANS FOR VARYING SAID SIGNAL FROM SAID LOW REFERENCE VALUE TO SAID HIGH REFERENCE VALUE, COMPARATOR MEANS IN SAID COMPARATOR CIRCUIT AND CONNECTED TO SAID SENSOR FOR SENSING WHEN THE SIGNAL OF THE COMPARATOR CIRCUIT EQUALS THE SENSOR SIGNAL, A PULSE GENERATOR CONNECTED TO SAID MEANS FOR VARYING SAID COMPARATOR CIRCUIT SO AS TO BE OPERATED COINCIDENTALLY THEREWITH FOR TRANSMITTING PULSES FROM THE THE COMPARATOR SIGNAL VARIES FROM SAID LOW REFERENCE VALUE TO SAID HIGH REFERENCE VALUE, THE NUMBER OF PULSES GENERATED FROM THE TIME THE COMPARATOR SIGNAL EQUALS SAID LOW REFERENCE VALUE UNTIL IT REACHES THE VALUE OF SAID SENSOR SIGNAL BEING PORPORTIONAL TO THE VALUE SAIDSENSOR SIGNAL WOULD HAVE IF THE SENSOR SIGNAL AND COMPARATOR SIGNAL EACH VARIES LINEARLY FROM SAID LOW REFERENCE VALUE TO SAID HIGH REFERENCE VALUE, A PULSES COUNTER AND GATE MEANS FOR CONNECTING THE PULSE CONTER O THE PULSE GENERATOR FROM THE TIME TH COMPARATOR SIGNAL IS AT SAID LOW REFERENCE VALUE UNTIL THE COMPARATOR SIGNAL EQUALS SAID SENSOR SIGNAL, SAID GATE MEANS INCLUDING A GATE CONTROL SYSTEM CONNECTED TO THE COMPARATOR CIRCUIT SO AS TO BE OPERATED THEREBY, SAID GATE CONTROL SYSTEM INCLUDING A MODULATOR CONNECTED TO THE COMPARATOR CIRCUIT AND TO AN A.C. REFERENCE FOR PROVIDING AN OUTPUT SIGNAL IN PHASE WITH THE A.C. REFERENCE WHEN THE COMPARATOR SIGNAL HAS A VALUE BETWEEN SAID LOW REFERENCE VALUE AND WHEN IT EQUALS SAID SENSOR SIGNAL AND FOR PROVIDING AN OUTPUT SIGNAL OUT OF PHASE WITH SAID A.C. REFERENCE WHEN THE COMPARATOR SIGNAL HAS A VALUE BETWEEN SAID SENSOR SIGNAL VALUE AND SAID HIGH REFERENCE VALUE.

Claim 2

THE SYSTEM COMPRISING A ISGNAL SENSOR FOR PROVIDING A SENSOR SIGNAL WHICH VARIES NON-LINEARLY IN RESPECT TO THE FUNCTION BEING SENSED FROM A LOW REFERENCE VALUE TO A HIGH REFERENCE VALUE, A COMPARATOR CIRCUIT FOR PROVIDING A COMPARATOR SIGNAL, SAIDCIRCUIT INCLUDING MEANS FOR VARYING SAID SIGNAL FROM SAID LOW REFERENCE VALUE TO SAID HIGH REFERENCE VALUE, COMPARATOR MEANS IN SAID COMPARATOR CIRCUIT AND CONNECTED TO SAID SENSOR FOR SENSING WHEN THE SIGNAL OF THE COMPARATOR CIRCUIT EQUALS THE SENSOR SIGNAL, A PULSE GENERATOR CONNECTED TO SAID MEANS FOR VARYING SAID COMPARATOR CIRCUIT SO AS TO BE OPERATED COINCIDENTALLY THEREWITH FOR TRANSMITTING PULSES FROM THE THE COMPARATOR SIGNAL VARIES FROM SAID LOW REFERENCE VALUE TO SAID HIGH REFERENCE VALUE, THE NUMBER OF PULSES GENERATED FROM THE TIME THE COMPARATOR SIGNAL EQUALS SAID LOW REFERENCE VALUE UNTIL IT REACHES THE VALUE OF SAID SENSOR SIGNAL BEING PORPORTIONAL TO THE VALUE SAIDSENSOR SIGNAL WOULD HAVE IF THE SENSOR SIGNAL AND COMPARATOR SIGNAL EACH VARIES LINEARLY FROM SAID LOW REFERENCE VALUE TO SAID HIGH REFERENCE VALUE, A PULSES COUNTER AND GATE MEANS FOR CONNECTING THE PULSE CONTER O THE PULSE GENERATOR FROM THE TIME TH COMPARATOR SIGNAL IS AT SAID LOW REFERENCE VALUE UNTIL THE COMPARATOR SIGNAL EQUALS SAID SENSOR SIGNAL, SAID GATE MEANS INCLUDING A GATE CONTROL SYSTEM CONNECTED TO THE COMPARATOR CIRCUIT SO AS TO BE OPERATED THEREBY, SAID GATE CONTROL SYSTEM INCLUDING A MODULATOR CONNECTED TO THE COMPARATOR CIRCUIT AND TO AN A.C. REFERENCE FOR PROVIDING AN OUTPUT SIGNAL IN PHASE WITH THE A.C. REFERENCE WHEN THE COMPARATOR SIGNAL HAS A VALUE BETWEEN SAID LOW REFERENCE VALUE AND WHEN IT EQUALS SAID SENSOR SIGNAL AND FOR PROVIDING AN OUTPUT SIGNAL OUT OF PHASE WITH SAID A.C. REFERENCE WHEN THE COMPARATOR SIGNAL HAS A VALUE BETWEEN SAID SENSOR SIGNAL VALUE AND SAID HIGH REFERENCE VALUE.
