摘要： An altitude reporter comprising an altimeter, electro-optical means for tracking the position of the indicator of the altimeter, an encoder for registering the position of the indicator and providing pulse group series output corresponding to such a position, and means for operatively connecting the encoder to the electro-optical tracking means. This connecting means is effective, when the indicator moves in one direction, to operate the encoder to add increments of such movement and, when the indicator moves in the opposite direction, to operate the encoder to subtract like increments of movement. The encoder and the stepper motors which drive the encoder in response to electrical signals from the electro-optical means constitute a register.

摘要： A SYSTEM COMPRISING AN OUTPUT MEANS AND CIRCUIT MEANS FOR OPERATING THE OUTPUT MEANS, THE CIRCUIT MEANS INCLUDING ONE NETWORK OR CHANNEL FOR DRIVING THE OUTPUT MEANS IN ONE DIRECTION AND A SECOND NETWORK OR CHANNEL FOR DRIVING THE OUTPUT MEANS IN THE OPPOSITE DIRECTION. THE ONE NETWORK INCLUDES A FIRST AMPLIFIER MEANS ARRANGED TO OSCILLATE AT A FIRST PREDETERMINED FREQUENCY AND THE SECOND NETWORK INCLUDES A SECOND AMPLIFIER MEANS ARRANGED TO OSCILLATE AT A SECOND AND SIGNIFICANTLY DIFFERENT PREDETERMINED FREQUENCY, WHEREBY THE LIKELIHOOD THAT SPURIOUS SIGNALS DEVELOPED BY OPERATION OF ONE OF SAID NETWORKS WILL CAUSE OPERATION OF ONE OF SAID WORKS IS SUBSTANTIALLY ELIMINATED. PREFERABLY, EACH AMPLIFIER MEANS IS A PULSE-TYPE OSCILLATOR, THE OUTPUT OF WHICH IS CONTROLLED BY AN INPUT SIGNAL CHARGING A CONTROL CAPACITOR TO A PREDETERMINED VOLTAGE LEVEL. IN ONE AMPLIFIER MEANS, THIS CAPACITOR PROVIDES ONE CAPACITANCE AND, IN THE OTHER AMPLIFIER MEANS, THIS CAPACITOR PROVIDES ANOTHER AND SIGNIFICANTLY DIFFERENT CAPACITANCE.
