    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 pneumatic vehicle tire includes a carcass, a bead with a bead core arranged in the bead, and a first sensor located within the bead. The first sensor delivers signals which are correlated to frictional forces transmitted by the pneumatic vehicle tire during operation. This sensor has a first end and a second end, wherein the first end includes a heel attached to the bead core and the second end extends radially outward from the bead core within the tire. A plurality of such sensors can be included in each tire, some for measuring longitudinal forces in a circumferential direction of the tire and others for measuring lateral forces in an axial direction of the tire.

    Abstract: A sensor developing a digital output in response to force induced deflection in which the deflection is of a beam formed to have, under stress, a surface undulate in both compression and tension. The signal is developed from piezoelectric transducers connected in a pair of oscillator circuits utilizing surface acoustic wave paths through, respectively, the tension and the compression portions of the beam surface. The frequencies of the oscillators are compared and the frequency difference resulting from beam deflection is sent as a signal to a counter to give a digital read out of the force causing the deflection. The beam is formed of steel and the piezoelectric surface for the surface waves and the interdigitated conductors forming the transducers are deposited by thin film techniques on the beam.
