    摘要: A magnetic field sensor comprises a substrate and a moving part which is displaced when subjected to a Laplace force. There is a gauge for measuring the displacement of the moving part. There is a suspended lever that is rotationally displaced about an axis of rotation at right angles to the direction of displacement of the moving part. The lever is connected to the moving part to transmit displacement of the moving part to the lever to cause rotation of the lever about the axis of rotation. The lever is also connected to a first part of the gauge. The sensor comprises a hinge that connects the lever to the substrate. The hinge allows the rotation of the lever about its axis of rotation and is rigid to allow for a lever arm effect. The second part of the gauge is fixed with no degree of freedom to the substrate.

    摘要: A method for fabricating an integrated electronic compass and circuit system. The fabrication method begins with providing a semiconductor substrate comprising a surface region. One or more CMOS integrated circuits are then formed on one or more portions of the semiconductor substrate. Once the CMOS circuits are formed, a thickness of dielectric material is formed overlying the one or more CMOS integrated circuits. A substrate is then joined overlying the thickness of the dielectric material. Once joined, the substrate is thinned to a predetermined thickness. Following the thinning process, an electric compass device is formed within one or more regions of the predetermined thickness of the substrate. Other mechanical devices or MEMS devices can also be formed within one or more regions of the thinned substrate.

    摘要: A remote, noncontact temperature determination method and apparatus is provided, which is operable to determine the temperature of a conducting member forming a part of or in operative thermal communication with an object of interest. The method comprises the steps of first inducing a closed vortex eddy current (28) in a conducting member (16, 38, 44) by subjecting the member (16, 38, 44) to a magnetic field, such that the corresponding eddy current magnitude changes exponentially over time. A characteristic time constant of the exponential current magnitude changes is then determined, and this is used to calculate the temperature of the object. The apparatus (24) includes a field transmitting coil (14) coupled with a waveform generator (12) for inducing the eddy current (28), and a field receiving coil assembly (18) which detects the corresponding magnetic field induced by the eddy current (28). Using the invention, temperature determinations can be made which are substantially independent of the relative distance and/or angular orientation between the conducting member (16, 38, 44) and the field receiving coil assembly (18).

    摘要: First and second complementary voltage signals are operatively coupled across a series circuit comprising first and second sense resistors and a circuit element therebetween. An output signal responsive to the self-impedance of the circuit element is generated responsive at least one of a voltage across the first sense resistor and a voltage across the second sense resistor, and at least one of the first and second complementary voltage signals is controlled responsive to the output signal so as to provide for attenuating at least one noise signal having a frequency that is substantially different from a frequency of the first and second complementary voltage signals.

    摘要: A magnetic field sensor device (2) is described that comprises an oscillatory member (8) and current control means (6). The current control means (6) is arranged to pass an alternating current (AC) along at least first (10) and second (12) current paths provided through the oscillatory member (8) and is arranged to provide magnetic gradiometer mode operation (i.e. to measure magnetic field gradient) in which current flow through the first current path (10) is in substantially the opposite direction to current flow through the second current path (12). The current control means (6) can also prove magnetometer mode operation (i.e. to measure magnetic field strength). The magnetic field sensor (2) may be used in a compass.
