Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
102 words
THE METHOD OF SIMULATING THE PRESENCE OF AN ANGULAR VELOCITY GAGE IN AN AUTOMATIC GUIDANCE CONTROL SYSTEM FOR A CRAFT COMPRISING THE STEPS OF SENSING THE ANGULAR DISPLACEMENT OF THE CRAFT TO PROVIDE A FIRST ELECTRICAL SIGNAL, AND SENSING THE ANGULAR ACCELERATION OF THE CRAFT TO PROVIDE A SECOND ELECTRICAL SIGNAL, DIFFERENTIATING THE FIRST ELECTRICAL SIGNAL WITH RESPECT TO A TIME-CONSTANT OF UNITY TO PROVIDE A THIRD SIGNAL, INTEGRATING THE SECOND SIGNAL WITH RESPECT TO A TIME-CONSTANT OF UNITY TO PROVIDE A FOUR SIGNAL, AND ADDING SAID THIRD AND FOURTH SIGNALS TO PRODUCE A FIFTH SIGNAL AS AN INDICATION OF ANGULAR VELOCITY.
