Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
100 words
AN OSCILLATOR SYSTEM FOR AN ELECTRONIC TIMEPIECE, COMPRISING A PAIR OF TRANSISTORS, A FEEDBACK CIRCUIT INTERCONNECTING SAID TRANSISTORS, SAID PAIR OF TRANSISTORS AND FEEDBACK CIRCUIT FORMING AN ELECTRONIC OSCILLATOR CIRCUIT ADAPTED TO OSCILLATE AT A FIRST FREQUENCY, A RESONATOR ADAPTED TO OSCILLATE AT A SECOND FREQUENCY EXCEEDING THE SAID FIRST FREQUENCY, A COIL ELECTROMAGNETICALLY COUPLED WITH THE SAID RESONATOR FOR TRANSMITTING DRIVING ENERGY TO SAID RESONATOR AND FOR RECEIVING CONTROL SIGNALS FROM THE SAID OSCILLATING RESONATOR, AND A NONLINEAR CIRCUIT ELEMENT SERIES-CONNECTED BETWEEN SAID COIL AND SAID OSCILLATOR CIRCUIT, WHEREBY THE SAID OSCILLATOR CIRCUIT IS SYNCHRONIZED BY SAID CONTROL SIGNALS.
