Abstract: A load cell for use in dynamic testing apparatus for mechanically testing samples includes an accelerometer mounted in the load cell on the same axis as the line of action of the mechanical force applied to the specimen under test. The resultant signal from the combination of the normal output from the load cell and the output from the accelerometer compensates for errors introduced by the mass of the moving grip used to grip the specimen in the apparatus.

Abstract: 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.

Abstract: A SAW based sensor having a base and a lid engageable with the base to form an internal cavity therewith. A substrate is supported in the cavity on either tile base or the lid 13 and a dimple 16 is formed on the other which extends towards the substrate so as to engage against the substrate and apply a preload thereto. The base and lid include complementary threads by means of which they are attachable to each other. The preload applied to the substrate by the dimple 16 is adjustable by varying the rotational position of the lid relative to the base.

Abstract: A pressure monitor has a base and a lid secured to the base to define a substantially fluid tight chamber. At least part of the lid is flexible and forms a diaphragm which deflects responsive to changes in fluid pressure surrounding the monitor. A projection provided on the diaphragm transmits movement thereof to a distortable substrate located within the chamber. A first SAW device is mounted on the distortable substrate, and at least a second and third SAW device are mounted within the chamber. The second SAW device carried on a reference substrate section has its direction of propagation inclined at an angle to the direction of propagation of at least one of the first and third SAW devices. This way movement of the diaphragm induced by a change in pressure in the zone surrounding the monitor results in distortion of the distortable substrate, which is measurable by the SAW device mounted thereon, without distorting said reference substrate section.

Abstract: A circular shaft having a platform formed on it by machining a circular flat into the surface of the shaft. A channel extends around the periphery of the circular flat with a depth in the range of 10 to 15% of the diameter of the shaft and in the range of 30 to 50% of the width/diameter of the platform. The width of the platform is 4 to 7% of the diameter of the shaft. A sensor is mounted on the platform, whereby the formation of the platform and surrounding channel reduces the strain arising in the device which is transferred to the sensor.

Abstract: A sensor has a body having a tapered locking surface, and engages in a component with a mounting surface having a complementary taper to the tapered locking surface of the body. The body is positioned on the component with the tapered locking surface aligned with the mounting surface, and an axial force is applied to the body to drive the tapered locking surface into engagement with the complementary taper of the mounting surface. The body is then fixed relative to the component by swaging outwards a skirt on the body into engagement with a lower surface of the component.
