BOARD FOR MEASURING ADJUSTMENT OF TURNING ANGLES OF CONTROL WHEELS FOR VEHICLES Russian patent published in 1995 - IPC

FIELD: vehicles. SUBSTANCE: wheels of vehicle go over stationary platforms. When front wheel intersects with light beam running from supplementary illuminator to supplementary photodetector, voltage at the output of supplementary photodetector drops to zero level, this results in negative voltage jump. This results in negative pulse generated at output of amplifier-generator which translates signals from supplementary photodetector to pulses. Generated signal is received at first input of NOR gate. The same pulse enters counting input of flip-flop and switches it from 0 state to 1 state. When moving wheel intersects with light beam running from main illuminator to main photodetector, output of amplifier-generator outputs negative pulse that enters second input of NOR gate which outputs received signal to counting input of flip-flop. This results in switch of flip-flop from 1 state to 0 one. As the result of switching flip-flop from 0 state to 1 state and back from 1 state to 0 one, pulse is generated at its output. Results are recorded by registration unit. EFFECT: increased functional capabilities. 4 dwg
