摘要： In a sensor for measuring angular velocity a body is formed from a planer substrate The body defines a beam, the opposed ends of which are adapted to be fixed in position, the beam having a preferential bending direction which makes an acute angle with the plane of the planar substrate. The beam carries an inertia mass comprising two arms interconnected by a connecting bar, the central part of the connecting bar being formed integrally with part of the beam. Capacitative plates located adjacent a conductive layer on the arms are provided with potentials which cause the inertia mass to rotate about the axis of the connecting bar with a “see-saw” action which, because of the configuration of the beam leads to a rotational oscillation of the inertia mass in the plane of the substrate. If the arrangement is rotated about an axis coincident with the connecting bar, the inertia mass rotates about an axis coincident with the beam with an oscillating rotation. This is detected by capacitative plates to determine angular velocity.

摘要： A modulator is provided in operative engagement with a sensor element having a plurality of electrodes. The modulator has a single-bit quantizer electrically connected to a digital accumulator. The accumulator accumulates output information received from the single-bit quantizer. The accumulator converts the accumulated output information received from the single-bit quantizer to a multi-bit feedback signal and sends the multi-bit feedback signal in a primary feedback loop back to the sensor element. The quantizer sends a single-bit feedback signal in a secondary feedback loop back to a point before the quantizer.

摘要： An energy harvesting system is arranged to harvest energy generated by a rotating tire. The system comprises a chamber holding fluid and an energy converter arranged to extract kinetic energy generated by a flow of the fluid, the flow being induced by a deformation of the chamber during the tire rotation, and further arranged to convert the kinetic energy into electrical energy. A method of harvesting energy generated by a rotating tire is also provided.
