摘要： The disclosure describes a magnetic circuit assembly that includes a magnet assembly and an excitation ring. The magnet assembly defines a central axis and includes a pole piece and a magnet underlying the pole piece. The excitation ring includes a base and an outer ring positioned around the magnet assembly. The base includes a platform layer underlying the magnet, an upper base layer underlying the platform layer, and a lower base layer underlying the upper base layer. The outer ring overlies the upper base layer and is configured to couple to an outer radial portion of a proof mass assembly. The platform layer and lower base layer are made from high coefficient of thermal expansion (CTE) materials, while the upper base layer and outer ring are made from low CTE materials. Each relatively high CTE material has a higher CTE than each relatively low CTE material.

摘要： A system (10) and method for controlling actuation of a vehicle safety device (12) in response to an impact to a first portion (14) of the vehicle includes a ferromagnetic element (16) mechanically coupled with the first portion (14) of the vehicle so as to receive elastic strain waves generated as a result of plastic deformation of the first portion (14) of the vehicle. A permanent magnet (52) is mounted on the vehicle adjacent to the ferromagnetic element (16) so that the ferromagnetic element (16) itself influences the magnetic field. An induction coil (44) is also mounted on the vehicle so as to fall within the magnetic field generated by the magnet (52). Upon plastic deformation of the first portion (14) of the vehicle, the ensuing elastic strain waves elastically deform the ferromagnetic element (16) to vary its ferromagnetic properties and, in turn, alter the magnetic field so as to induce an electromotive force voltage in the induction coil (44). A signal processor (34) receives the electromotive force voltage induced in the induction coil (44) by the varying magnetic field. The signal processor (34) activates the safety device (12) when the electromotive force voltage, or an appropriate measure derived from the electromotive force voltage, exceeds a predetermined threshold.

摘要： A vehicle restraint system (20) that includes an impact sensor (22) coupled by fiber optics (50,64,66) to an igniter (26) for inflating an air bag (28). The impact sensor includes a permanent magnet (32) disposed within a cavity (34) and biased by magnetic force toward one end of the cavity, motion of the magnet in the cavity being sensed by a weigand wire (44) or Hall (86) sensor for igniting the air bag. Facility (72) is disposed externally of the cavity for selectively adjusting the bias of the sensor and/or moving the magnet into proximity with the Hall effect or weigand wire sensor to test operative condition of the sensor.

The movable magnetic body (4) extends through the primary coils (6a,6b) and the secondary coils (7a,7b) and has its both ends protruding from the coils. Leaf springs (3a,3b) are provided to support the protruding ends of the movable magnetic body (4). The case (2) comprises a cylindrical body (2-1) surrounding the outer periphery of the differential transformer and lids (2-2) closing openings of the body (2-1) at both ends thereof. Between the lids (2-2) and both ends of the movable body (4) predetermined gaps (g) are provided through which a magnetic flux can flow. The leaf springs (3a,3b) are secured in position between end faces of the body and the lids.

摘要： An acceleration detector has a case and a movable magnetic body mounted in the case and supported by a leaf spring secured to the case so as to be movable in two opposite directions in response to acceleration. Stoppers made of a magnetic material are secured to the inner wall of the case at both ends of the magenetic body, with predetermined gaps left therebetween. Two pairs of primary and secondary coils are provided around the magnetic body for producing a difference in output between the secondary coils according to the displacement of the magnetic body.
