摘要： An accelerometer which uses a piezoelectric element (34) which has flat faces on opposite sides thereof and which is mounted on a support (38) is characterised firstly by the piezoelectric element being mounted with one flat face (36) bonded to the support plate and the other flat face (40) free so that it operates as a radial expander when subjected to axial forces, and secondly by an electrical contact element (46) extending through a bore (48) through the support plate (38) and the piezoelectric element (34) and being connected to the flat face (40) of the piezoelectric element remote from the support plate (38). The support for the piezoelectric element is preferably a plate (42) integral with a central post (44). The contact wire (46) is held rigid and is protected by the other component parts, and the mounting of the piezoelectric element itself reduces the base strain sensitivity of the device.

摘要： An accelerometer, comprising a main body (2), acceleration responsive means (1) mounted from the main body in such manner as to be movable on application to the accelerometer of acceleration along a single direction (A-B) or about a single axis, sensor means (8, 9, 10) for sensing the magnitude and sense of any such movement of the acceleration responsive means relative to the main body and for providing output characteristic of the such movement; means for producing from the sensor output digital signals (12, 15); means (12, 18) for deriving from the digital signals control signals which are utilisable to operate means (5, 6) for applying force to the responsive means (1) to counteract said movement, and means for producing output signals characteristic of the applied forces.

摘要： An electronic controller unit for at least one transducer, characterised in that the control circuit incorporates a microprocessor (1) for enabling operational calibration of each transducer (6, 7) associated therewith in such manner as to take into account zero output level influencing factors to establish a compound calibration relationship for each such transducer (6, 7); means for storing each such calibration relationship; and means (1) for comparing the instantaneous output of each transducer with its stored associated calibration relationship value for the ambient temperature prevailing at the time of said instantaneous output to produce a temperature corrected output value for each said transducer. The control circuit is particularly intended for use with intelligent suspension systems for motor vehicles.

摘要： An accelerometer unit characterised by first and second piezo-electric elements (5, 6) mounted upon opposed surfaces of an electrically conductive sheet, plate or the like (1), and in that the sheet, plate or the like is adapted to be centrally supportable by support (12) such that the first and second piezo-electric elements are subjectable to similar forces upon subjecting the piezo-electric elements to acceleration forces. The elements (5, 6) are connected electrically in parallel so that the effects of one piezo-electric element are caused to negate electrical output arising from pyroelectric effects of the other piezo-electric element. A combined band pass filter and amplification circuit in which at least a part of the capacitance (37) of the initial high frequency pass filter of the circuit is provided by the capacitance of the piezo-electric elements.
