The stator antenna is configured to be inductively coupled to the rotor antenna. The stator electronics are coupled to receive, via the stator antenna, feedback data and are configured, in response thereto, to generate and transmit, via the stator antenna, power signals at a power level magnitude based in part on the feedback data. The rotor electronics are attached to the rotor and are coupled to receive, via the rotor antenna, the power signals transmitted by the stator electronics. The rotor electronics are configured to determine the power level magnitude of the power signals, generate the feedback data, the feedback data at least including information representative of the determined power level magnitude, and transmit, via the rotor antenna, the feedback data.

Abstract: A synthetic phased array surface acoustic wave sensor to quantify bolt tension and a method for determining or estimating the tension in bolts using surface acoustic waves (SAWs). The tension is determined or estimated by using the reflection of SAWs created by the bolt head interference with the underlying surface. Increments in the bolt tension raise the points of interaction between the waves and the bolt head (real area of contact), and hence the position of the reflective boundaries. The variations are estimated using known techniques (e.g., linear synthetic array imaging technique). A singular transducer is actuated from predefined positions to produce an array of signals that are subsequently arranged and added to construct an acoustic image.

Abstract: A method and system for packaging and mounting a SAW sensor to an automobile flex plate for use in sensing torque. A SAW sense die can be adhesively bonded to a metal disc comprising semicircular holes formed at the periphery of the metal disc. An insulator (e.g., plastic) constituting lead pins can be adhesively bonded to the metal disc that surrounds the sense die in a particular orientation. A cap (e.g., plastic) can then be bonded over the insulator. The metal disc, along with the SAW sense die, can be aligned to the flex plate by matching the semicircular holes on the metal disc with a semicircular hole configured at the edge of a circular cutout on the flex plate. The aligned metal disc and the flex plate can be bonded together by, for example, laser welding.

Abstract: The present invention relates to a method of and a device for detecting torque, and more particularly to a method of and a device for detecting torque which are suitable for use at the time of a high-velocity rotation or for detecting a very small torque. An annular or ring-like elastic member is interposed between, for instance, a drive shaft and a load shaft constituting a torque-transmitting shaft system, and is formed with slits with parts of an outer periphery thereof left unslitted to be divided in the axial direction so that the member is of a configuration easily deformable in the radial direction thereof by means of torque. A non-contact type displacement sensor is provided for measuring the deformation of the elastic member, and a marker is attached on the drive shaft to provide a positional signal for use as a sampling signal. The signal of the displacement sensor is extracted on the basis of the sampling signal to be stored and held. At the time when that value of that deformation signal has exceeded a threshold, an overload signal is output, and further the torque load is released responsively to that output signal.

The first structure Y-axis connecting portions are disposed on a positive side and a negative side of a Y-axis relative to the strain body, and the second structure X-axis connecting portions are disposed on a positive side and a negative side of an X-axis relative to the second structure. The strain body includes four deformable bodies each including a displacement portion that is displaced in a Z-axis direction by elastic deformation. The deformable bodies are respectively disposed in a first quadrant, a second quadrant, a third quadrant, and a fourth quadrant. The detection element includes a capacitive element that detects a change in capacitance value by a displacement of the displacement portion of each of the deformable bodies in the Z-axis direction.
