Time measurement device arranged to locate centers of energy of spaced pulses

Claim 1

A SYSTEM FOR LOCATING THE CENTER OF ENERGY OF A PULSE OF ENERGY COMPRISING, IN COMBINATION: (A) A TRIGGERED PULSE GENERATOR HAVING ONE INPUT AND FIRST AND SECOND OUTPUTS, SAID PULSE GENERATOR PRODUCING COMPLEMENTARY OUTPUT SIGNALS; (B) FIRST AND SECOND GATES HAVING TWO INPUTS AND ONE OUTPUT; (C) SAID ENERGY PULSE BEING COUPLED TO ONE OF SAID INPUTS OF EACH OF SAID FIRST AND SECOND GATES; (D) SAID COMPLEMENTARY OUTPUT SIGNALS BEING RESPECTIVELY COUPLED TO THE OTHER OF SAID INPUTS OF EACH OF SAID FIRST AND SECOND GATES FOR CONTROLLING SAID GATES; (E) FIRST AND SECOND ENERGY INDICATING MEANS RESPECTIVELY COUPLED TO SAID FIRST AND SECOND GATES FOR RESPECTIVELY PRODUCING OUTPUTS INDICATIVE OF THE ENERGY IN SAID OUTPUTS OF SAID FIRST AND SECOND GATES; (F) COMPARING MEANS COUPLED TO SAID FIRST AND SECONDD ENERGY INDICATING MEANS FOR PRODUCING A DC OUTPUT SIGNAL INDICATIVE OF THE ENERGY DIFFERENCE OF SAID OUTPUTS OF SAID FIRST AND SECOND ENERGY INDICATING MEANS; (G) CONTROL MEANS COUPLING SAID DC SIGNAL TO SAID PULSE GENERATOR FOR CONTROLLING THE TRIGGERING TIME OF SAID PULSE GENERATOR SO THAT THE ENERGY IN SAID FIRST GATE OUTPUT EQUALS THE ENERGY IN SAID SECOND GATE OUTPUT, WHEREBY SAID TRIGGERING TIME OF SAID PULSE GENERATOR INDICATES THE CENTER OF ENERGY OF SAID ENERGY PULSE; (H) SAID FIRST AND SECOND ENERGY INDICATING MEANS EACH INCLUDING A SQUARING AMPLIFIER WHOSE VOLTAGE OUTPUT IS PROPORTIONAL TO THE SQUARE OF THE VOLTAGE INPUT, WHICH AMPLIFIERS ARE EACH SERIALLY COUPLED TO A LINEAR INTEGRATOR WITH SAID OUTPUTS OF SAID FIRST AND SECOND GATES BEING RESPECTIVELY COUPLED TO SAID SQUARING AMPLIFIERS; (I) SAID FIRST GATE BEING ENABLED SO THAT A FIRST PORTION OF SAID ENERGY PULSE IS COUPLED TO SAID SQUARING AMPLIFIER OF SAID FIRST ENERGY INDICATING MEANS; AND (J) SAID SECOND GATE BEING ENABLED SO THAT A SECOND PORTION OF SAID ENERGY PULSE IS COUPLED TO SAID SQUARING AMPLIFIER OF SAID SECOND ENERGY INDICATING MEANS.

Claim 2

A SYSTEM FOR LOCATING THE CENTER OF ENERGY OF A PULSE OF ENERGY COMPRISING, IN COMBINATION: (A) A TRIGGERED PULSE GENERATOR HAVING ONE INPUT AND FIRST AND SECOND OUTPUTS, SAID PULSE GENERATOR PRODUCING COMPLEMENTARY OUTPUT SIGNALS; (B) FIRST AND SECOND GATES HAVING TWO INPUTS AND ONE OUTPUT; (C) SAID ENERGY PULSE BEING COUPLED TO ONE OF SAID INPUTS OF EACH OF SAID FIRST AND SECOND GATES; (D) SAID COMPLEMENTARY OUTPUT SIGNALS BEING RESPECTIVELY COUPLED TO THE OTHER OF SAID INPUTS OF EACH OF SAID FIRST AND SECOND GATES FOR CONTROLLING SAID GATES; (E) FIRST AND SECOND ENERGY INDICATING MEANS RESPECTIVELY COUPLED TO SAID FIRST AND SECOND GATES FOR RESPECTIVELY PRODUCING OUTPUTS INDICATIVE OF THE ENERGY IN SAID OUTPUTS OF SAID FIRST AND SECOND GATES; (F) COMPARING MEANS COUPLED TO SAID FIRST AND SECONDD ENERGY INDICATING MEANS FOR PRODUCING A DC OUTPUT SIGNAL INDICATIVE OF THE ENERGY DIFFERENCE OF SAID OUTPUTS OF SAID FIRST AND SECOND ENERGY INDICATING MEANS; (G) CONTROL MEANS COUPLING SAID DC SIGNAL TO SAID PULSE GENERATOR FOR CONTROLLING THE TRIGGERING TIME OF SAID PULSE GENERATOR SO THAT THE ENERGY IN SAID FIRST GATE OUTPUT EQUALS THE ENERGY IN SAID SECOND GATE OUTPUT, WHEREBY SAID TRIGGERING TIME OF SAID PULSE GENERATOR INDICATES THE CENTER OF ENERGY OF SAID ENERGY PULSE; (H) SAID FIRST AND SECOND ENERGY INDICATING MEANS EACH INCLUDING A SQUARING AMPLIFIER WHOSE VOLTAGE OUTPUT IS PROPORTIONAL TO THE SQUARE OF THE VOLTAGE INPUT, WHICH AMPLIFIERS ARE EACH SERIALLY COUPLED TO A LINEAR INTEGRATOR WITH SAID OUTPUTS OF SAID FIRST AND SECOND GATES BEING RESPECTIVELY COUPLED TO SAID SQUARING AMPLIFIERS; (I) SAID FIRST GATE BEING ENABLED SO THAT A FIRST PORTION OF SAID ENERGY PULSE IS COUPLED TO SAID SQUARING AMPLIFIER OF SAID FIRST ENERGY INDICATING MEANS; AND (J) SAID SECOND GATE BEING ENABLED SO THAT A SECOND PORTION OF SAID ENERGY PULSE IS COUPLED TO SAID SQUARING AMPLIFIER OF SAID SECOND ENERGY INDICATING MEANS.
