Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
125 words
A SIGNAL GENERATOR COMPRISING: AN ASTABLE MULTIVIBRATOR INCLUDING TWO CURRENT PATHS AND HAVING AN OSCILLATORY MODE IN WHICH SAID PATHS ALTERNATE WITH EACH OTHER IN CONDUCTING CURRENT AND A NONOSCILLATORY MODE IN WHICH SAID PATHS CONDUCT CURRENT CONTINUOUSLY; AND FEEDBACK MEANS INCLUDING FIRST GATING MEANS COUPLED TO SAID PATHS FOR DEVELOPING A VOLTAGE SIGNAL IN RESPONSE TO THE CONTINUOUS CONDITION OF CURRENT IN SAID PATHS, A RELAXATION OSCILLATION COUPLED TO SAID FIRST GATING MEANS FOR GENERATING A TRIGGER PULSE IN RESPONSE TO SAID VOLTAGE SIGNAL, AND SECOND GATING MEANS COUPLED BETWEEN SAID RELAXATION OSCILLATOR AND ONE OF SAID PATHS AND RESPONSIVE TO SAID PULSE FOR TEMPORARILY REDUCING THE CONDUCTION OF CURRENT IN SAID ONE OF SAID PATHS TO TRIGGER SAID MULTIVIBRATOR INTO SAID OSCILLATORY MODE.
