摘要： A transducer arrangement comprising a magnetoresistive transducer including a magnetoresistive element responsive to magnetic flux passing therethrough in a predetermined direction to change its electrical resistance as a function of the intensity of the magnetic flux in the predetermined direction and a magnet to provide said magnetic flux. The transducer can include a permanent magnet having a planar surface with a magnetoresistive element offset from the axis of the magnet and optionally at an angle to the planar surface. The transducer can also include a concave surfaced magnet with the magnetoresistive element at an acute angle to the parallel flux lines emanating from the concave surface. As a further embodiment, the magnetoresistive element can be tilted on the magnet surface in two directions to provide a bias field and calibration. As a third embodiment, a high permeability pole piece can be positioned on the magnet surface between the magnet and the magnetoresistive element to minimize field variation due to nonuniformities in the magnet. There is also provided a module including an aluminum bracket mountable at the fore portion thereof and containing a magnetoresistive transducer circuit at the aft portion thereof, the circuit being coupled to a semiconductor circuit disposed at the center of the bracket. An epoxy resin encases the transducer circuit and semiconductor circuit as well as an optional cable or electrical connector at the fore portion of the bracket.

摘要： A fluid pressure sensor particularly useful for measuring pressure up to approximately 2000 psi has a hexport (12, 112, 212, 312) formed with a stop surface (26, 326) in a bottom wall (18) circumscribing a fluid pressure inlet (16). A pressure sensing module (22) is received on the stop surface and a distal end (40) of a wall (20, 120, 320) of the hexport is crimped to lock the pressure sensing module onto the stop surface with the stop surface limiting the amount of compression of an O-ring (30) disposed contiguous to and inboard of the stop surface. In one embodiment the crimp is placed directly on a metal ring (38) attached to a plastic connector (32) which in turn transfers the crimping force to the pressure sensing module. In other embodiments (FIGS. 2, 3) the crimp is placed directly in the pressure sensing module to form a subassembly. In one embodiment, a separate sleeve (142) member connects the subassembly to the plastic connector while in another embodiment the connector is provided with an extended skirt which snaps over the hexport to connect the connector to the subassembly. In yet another embodiment, the plastic connector (332) is formed with a strengthening flange (334) received around the pressure sensing module and the crimp is formed directly on the plastic connectors to reduce contact stresses in the crimp and compensate for crimp wall springback.

摘要： An accelerometer device particularly adapted for use in automotive safety air bag applications comprises an electrically insulating substrate having electrically conducting circuit paths, signal conditioning circuit components, and an accelerometer unit mounted thereon, the substrate being fixed in position on three pins within a housing. The accelerometer comprises a silicon mass movable in a silicon body relative to an integral silicon support to provide strain in the silicon body in response to acceleration and has piezoresistive sensors formed in the silicon body to be responsive to that strain to provide an electrical signal corresponding to the acceleration. A member having a selected configuration and thermal response characteristics suspends the accelerometer unit on the substrate with the piezoresistive sensors connected to the circuit paths with the piezoresistive sensors isolated from strain in the silicon body due to differences in thermal expansion between the silicon body, and the substrate during temperature changes likely to be encountered.

摘要： An accelerometer is shown with improved drop resistance for regulating automotive safety air-bag systems and the like. The device comprises a member of silicon semiconducting material having a central seismic mass mounted on a surrounding support by intervening beams, a pair of beams extending from each of four sides of the mass to the support and the mass being otherwise free of connection to the support to permit movement of the mass along an axis perpendicular to the plane of the support in highly sensitive response to acceleration forces along that axis. Each beam extends from a location near an end of one side of the mass so that the two beams extending from each side of the mass are widely spaced relative to each other to oppose rotational or twisting movement of the mass in response to off-axis acceleration forces to prevent damage to the beams during dropping of the accelerometer to the extent possible consistent with providing the desired sensitivity of response. Piezoresistive sensors are accommodated in selected beams to sense strain during movement of the mass to provide an output signal corresponding to acceleration force along the device axis. Stops limit movement of the mass along that axis to further avoid damage to the beams.

摘要： An accelerometer device comprises a silicon semiconductor member having a mass mounted on a support by integral beams extending between the mass and support to permit movement of the mass in response to acceleration. Piezoresistive sensors are accommodated in the beams for sensing strain in the beams during movement of the mass to provide an output signal from the device corresponding to the acceleration. The beams each have an end secured to the support and an end secured to the mass and taper intermediate the beam ends to provide a high and substantially uniform strain throughout the tapered section of the beam. The piezoresistive sensor is accommodated in the tapered beam section to be responsive to that high, uniform strain. Preferably the member has four beams mounting the mass, each beam has a tapered section extending from each end of the beam toward the center of the beam, and each beam section has a piezoresistive sensor accommodated therein to be responsive to the uniform strain within that beam section. The piezoresistive sensors are conveniently interconnected to compensate for off-axis acceleration in one direction by compensation within each leg of a bridge circuit and to compensate for off-axis acceleration in another direction by compensation within the full bridge circuit.
