TELEVISION DEVICE TO DETERMINE RANGE Russian patent published in 1997 - IPC

FIELD: TV equipment determining range. SUBSTANCE: proposed television device to determine range decreases time of determination of range thanks to insertion of small-sized television pickup and lens with horizontal marker, unit of two pickups of signal of start and finish of line, on-line storage, two coincidence circuits, subtracter and permanent storage. Lens with horizontal marker is rigidly coupled to small-sized television pickup and output of amplitude selector is connected to first inputs of first and second coincidence circuits which second inputs are correspondingly connected to first and second outputs of unit of two pickups of signal of start and finish of line and input is connected to first output of synchronizer. Besides this outputs of first and second coincidence circuits are correspondingly connected to first and second inputs of on-line storage having group of outputs connected to first group of inputs of subtracter. Second group of its inputs as well as third group of inputs of on-line storage are connected to group of outputs of azimuth pickup. Group of outputs of subtracter is connected to group of inputs of permanent storage which group of outputs is connected to group of second inputs of indicator. EFFECT: decreased time of determination of range. 2 dwg
