MOVABLE OBJECTS POSITION INDICATOR Russian patent published in 1994 - IPC

Abstract SU 1436846 A1

FIELD: TV engineering. SUBSTANCE: indicator has photoelectric converter 1, videoamplifier 2, analog-to-digital converter 3, sync generator 4, local sweep former 5, switch 6, control signal former 7 and channels 8 and 9 for measuring coordinates X and Y. Each channel is made of adders 10 and 19, scaling unit 11, fixation pulse former 12, extrapolation unit 13, shift register 14, extrapolation coefficient calculator 15, counter 16, error signal former 17, digital integrator 18 and digital-to-analog converter 20. Dynamic errors may be reduced due to introduction of switch 6 and former 7, and channel 8 and 9. EFFECT: improved precision of measurement. 7 dwg
