INERTIAL SIGNAL CONVERTER Russian patent published in 2008 - IPC G01C21/10 

FIELD: physics.

SUBSTANCE: invention pertains to measurement technology, specifically to devices consisting of converters of angular velocity and linear acceleration on several axes. The inertial signal converter consists of device for measuring linear acceleration and angular velocity, device for converting analogue signals into a digital code, a central computing device, secondary alternating and direct current sources, and a test control device. In each channel of the device for measuring angular velocity there are three load resistors which are commutable by signals from the central computing device. In each channel of the device for measuring linear acceleration there are three reference resistors which are commutable by signals from the central computing device. In the device for converting analogue signals into digital code, there are seven multiplexers, seven digital-analogue converters, a bus shaping unit, control register, control decoder, an entry decoder, a decoder for the read operation selection, read operation decoder, two calibration resistors, voltage stabiliser, three repeaters and three inverters, a dual switch, a control device on eight inverters, seven D-flip-flops, four logical 2NAND gates, and an AND gate. In the AC and DC secondary sources, the control pulse shaper is made from an inverter, eight D-flip-flops, a NAND gate, frequency divider and a JK-flip-flop. There is also an analogue integrator, comparator, two voltage stabilisers, three transformers and a transistor switch in the secondary sources. The secondary direct current source there is an RF interference filter, a transistor, two diodes, an electromagnetic relay, three capacitors, and a cell of buffer capacitors. In each of the four voltage converters there is input LC-filter, RC-circuit, field effect transistor, two differential amplifiers, transistor optoelectronic coupler, and reference voltage source. In the central computation device there are three optocoupling devices, buffer unit, electrically alterable read-only memory, programmable timer, decoder, instruction buffer, register for receiving and transmitting one-time commands, interrupt flip-flop, and open collector logical device. In the microprocessor of the central computing device there is an adder and a clock speed generator.

EFFECT: increased accuracy of measuring angular velocity and linear acceleration.
