DEVICE FOR MEASURING ACCELERATIONS Russian patent published in 2006 - IPC G01P15/13 

FIELD: possible use as sensitive element in stabilization, pointing and navigation systems, as well as in devices for measuring compensation-type mechanical values.

SUBSTANCE: device having two negative check connections, additionally has, in digital negative check connection, from output of reverse binary counter to input of second adding element - first stack register, second stack register, adder, additional inputs of which are outputs from reverse binary counter and from first and second stack registers, output register, comparison circuit, other input of which is connected to synchronization circuit through adding counter, second precision relay element, second voltage-current transformer. Additional inputs of low-digit reverse binary counter, low-digit final register, waiting synchronous generators, binary multiplier, reverse binary counter, output register and second precision relay element are connected to one of synchronization system outputs. Output from reverse binary counter is digital output of device. Insertion of two parallel negative check connection to device allows to make a device with increased precision with extended pass band, wherein given quality of transfer process is provided for by analog negative check connection, while extension of pass band is provided for by controlling precision relay element, by both main and difference signals from outputs of reverse binary counter and first and second stack register. Because digital negative check connection has low-digit reverse counter, low-digit final register, binary multiplier, matching circuits, reverse binary counter, first and second stack register, adder, output register of control circuit, adding counter, precision relay element, it is possible to make a device with decoupled transfer function K/S, stable under any K - amplification coefficient by open contour.

EFFECT: higher efficiency.
