ABSTRACT:
The novel miniaturized inclinometer for angle measurement with accurate measurement indicator is designed to monitor the angular motion of limbs. The device contains at least one inclinometer with signal conditioning electronics, including a microprocessor, placed within a miniature housing. A number of different sensors can be used and positioned in their housings so that their outputs vary as a function of their angle with respect to the gravity sector. The microprocessor controls a multiplexer, which controls the activities of the sensors; performs analog to digital conversions and measures the output curves from the sensor pairs to perform a conversion which results in a three hundred and sixty degree range with respect to gravity. Calibration data is stored in a read only memory and the microprocessor corrects variables to ensure accuracy and measures the difference in angle between the pairs of sensors.
