摘要： Aspects of the present invention are directed to using surface acoustic wave (SAW) sensors mounted on a disc coupling component in a powertrain to measure the torque generated by an automobile engine. The sensor may be positioned and oriented on the disc coupling component so that the phase velocities of SAWs propagating through active elements of the SAW sensors are aligned with principal strain components due to torque in the disc coupling component. The torque may be calculated by determining the difference between resonant frequencies of the active elements to suppress common-mode interference factors. In addition, SAW resonant frequencies may be communicated in a non-contacting manner by utilizing rotary and stationary couplers employing radio frequency (RF) signals. Moreover, SAW sensors may be activated and interrogated by employing targeted RF pulses having different carrier frequencies at or near respective resonant frequencies of each resonator in a SAW sensor.

摘要： A wheel nut assembly includes a stud (1), a main wheel nut (4) mountable on threads (3) provided on the stud, and a retaining nut (6) engageable with threads (5) provided on the stud to prevent accidental loosening of the wheel nut (4). The threads of the wheel nut (4) and the threads for the retaining nut (6) are of opposite hand. A cap (11) is slidably mounted on the retaining nut (6) and biased into a first position by a spring (16). The cap (11) includes multi-hexagonal profiles (12, 14) for engaging hexagonal profiles (13, 15) provided on the retaining nut (6) and on the main wheel nut (4). Accordingly, in the first position, the retaining nut (6) and the main wheel nut (4) are rotationally locked to each other and because of the opposite hand of the respective threads it is not possible to remove the retaining nut. To release the retaining nut (6), the cap (11) is grasped and pulled to the limit permitted by the spring (16) to permit rotation of the retaining nut (6) and removal thereof.

摘要： A device for measuring torsional distortion of a body comprises first and second clip portions each having a central part and two legs depending from the central part, each leg having adjacent the free end thereof a groove or projection for engaging a respective projection or groove (14) provided in the body (16) to mount the clip portion the body rotationally fastened therewith. A bridge interconnects the clip portion. The bridge is less stiff than the clip portions whereby relative rotational displacement of the clip portions caused by torsional distortion of the body will cause proportional deflection of the bridge. Means, for example a SAW device (15), are provided for measuring the deflection of the bridge to provide an indication of the torsional distortion which produces the deflection of the bridge. Also (20) for the interior all of a hollow body.

摘要： A pressure monitoring device includes a rigid base (2) which has secured thereto a lid (5) to define a hermetically sealed chamber (6). The lid (5) is of flexible metal material and the major surface (5A) of the lid forms a diaphragm which will deflect in response to changes in the pressure surrounding the device. A substrate (7) upon which a plurality of SAW devices are laid down is supported on a rigid frame (3A) of the base so that the central region thereof is unsupported between edges (11, 12). A dimple (10) is formed in the lid (5) and presses on a central region of the substrate (7). Changes in pressure will accordingly cause distortion of the central region of the substrate. The end regions (8, 9) of the substrate (7) carry further SAW devices so that, by analyzing the changes in characteristics of all the SAW devices a temperature compensated indication of pressure change, together with an indication of absolute temperature, may be provided by interrogating the SAW devices. The base (2) and the lid (5) are preferably both of metal alloy and may be secured together by soldering. Antennae associated with the SAW devices may be laid down as tracks on the surface of the base (2).

摘要： A locknut system having a projecting screw threaded member with a first external thread. A nut is mountable on the projecting screw threaded member by means of a corresponding thread. A second different screw thread is formed on the projecting screw threaded member. The second screw thread is of a different hand or a different pitch from the first screw thread. A locking member has a screw thread for engagement with the second screw thread of the projecting screw threaded member and has an engaging surface which can be brought into abutting contact with a corresponding engaging surface on the nut by mating the thread of the locking member with the second thread of the projecting screw threaded member. A coupling member operates to couple the locking member and the nut to substantially prevent relative rotation there between. One of the locking member and the coupling member carries a snap ring which snaps into engagement with a retaining recess provided on the other when the coupling member is mounted in its use configuration, to prevent accidental displacement of the coupling member from the locking member.
