DEVICE FOR MEASURING ACCELERATIONS Russian patent published in 2005 - IPC

FIELD: mechanical measurement engineering.

SUBSTANCE: device can be used as sensitive element in stabilization, guiding and navigation systems, it also can be used in devices for measuring compensation-type mechanical values. Two active parallel negative feedbacks are introduced into the device. First analog feedback goes from output of amplifier to one input of second adder which has output connected with input of torque generator through the following members connected in series: first logic gate, NOR gate which has second input connected with reference voltage generator via second logic gate, first precision relay element, ripple filter, high-pass filter, voltage-to-current first converter. The other negative feedback is digital. It goes from output of amplifier to second input of second adder through the following elements connected in series: first logic gate, NOR gate, first precision relay element, ripple filter, first adder, relay element, synchronous generators, RS flip-flop, first pair of AND gates, low-digit reversible binary counter, low-digit summing register, digital data- to-direct code converter, binary multiplier, second pair of AND gates, reversible binary counter, stack register, adder, output register, comparison circuit, summing counter, second precision relay element, second voltage-to-current converter. Elements introduced in both feedbacks resulted in creation of device into which basic and difference digital codes are formed in digital (pulse) feedback. The digital codes provide output of ripples digital data from output of reversible binary counter.

EFFECT: improved precision of measurement.
