摘要： A sensing device includes an RFID chip and a differential variable reluctance transducer (DVRT) sensor that can be read remotely with electromagnetic power provided to the device from a remote reader. The ac signal provided to the device by inductance is used for powering the RFID chip and exciting the sensor. Data read from the sensor can also be transmitted back to the reader using the power provided by the reader. The sensor circuit uses a lower amount of current than the RFID chip, so it does not contribute appreciably to device power requirements.

摘要： A network of wireless sensor nodes for wireless transmission to a base station is provided. The sensor nodes can provide real time streaming of data over separate frequency links that can all be received by the base station. The base station includes a receiver for receiving at multiple frequencies, error detection or correction, and analog outputs so sensor data can be provided to standard analysis systems that require analog signals as would be provided by wired sensors. The base station also provides an output indicating the presence of transmission error.

摘要： 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.

摘要： The novel differential variable reluctance transducer assembly is comprised of an ultra miniaturized device encased in stainless steel. The assembly contains a free sliding, magnetically permeable core and two coils surrounding the core. A split ring mounting adapter system allows for a variable gauge length and interchangeable mounting pins. A highly flexible core carrier tube and support wire allows for significant bending without failure, does not interfere with the coils detection of the core, and protects the core from corrosion. A sleeve strain relief sheath has been incorporated with the sensor to avoid excessive strain to lead wires during and after installation. The position of the core is detected by measuring the coils' differential reluctance and transmitted by means of wires or telemetry to measuring equipment.

摘要： This apparatus is adapted for replaceable implantation in soft body tissues for the measurement of the mechanical behavior of the soft tissues of the body. The apparatus consists of a thin walled tube containing a longitudinal slot down one side with at least one piezo-resistive strain gauge element bonded to its inner or outer walls. Tension in tissue fiber bundles results in a squeezing pressure against the sides of the tube, which produces a change in the shape of the tube and thus a change in the resistance of the strain gauge element. This resistance change is then measured and displayed. A method of inserting and removing the apparatus is also described, as are several techniques for calibration.
