ABSTRACT:
A pulse adder--subtracter difference transmitter to which electrical power is supplied includes first normally open switch means which temporarily closes in response to an event to transmit an electrical pulse, second normally open switch means which temporarily closes in response to an event to transmit an electrical pulse, movement means responsive to the pulse from the first switch means to move in one direction and responsive to the pulse from said second switch means to move in an opposite direction whereby the resulting movement of said means is proportional to the difference between the pulses from said first and second switch means and response means responsive to the resulting movement of the movement means to provide a signal which is proportional to the resulting movement.
