  • Patent number: 9664705
    Abstract: In an embodiment, a speed sensor includes a first portion, a second portion, and a third portion. The first portion includes a sensing assembly for generating a signal associated with a movement of an object external to the speed sensor. The second portion includes a wiring harness for transferring the generated signal to a device external to the speed sensor. The first portion and the second portion are joined. The third portion is over-molded over a point of the speed sensor where the first portion joins the second portion. Over-molding the third portion at the point may act to seal the point from outside contaminants. Moreover, over-molding the third portion at the point may act to strengthen the speed sensor at the point.

  • Patent number: 7578194
    Abstract: A differential liquid pressure sensor (10) has an upper housing (12) that mounts a connector portion (12a) and receives in a recess a sense element module (14). The sense element module is a body in which a generally U-shaped oil filled passageway (14h) is formed with openings at opposite ends provided on respective first and second diaphragm mounting surfaces. A fluid pressure sense element, such as a piezoresistive sense element (15) is disposed in one of the passageway openings and flexible metal diaphragms (14a, 14b) are mounted on the respective diaphragm mounting surfaces of the module facing a common direction. A lower housing (18) having first and second port connections for the respective diaphragms is disposed on the lower surface of the module.

  • Patent number: 6272927
    Abstract: A capacitive fluid pressure sensor (10, 10′, 10″) particularly adapted for use with fluids which are incompatible with conventional elastomeric fluid seals is shown in which a thin, relatively flexible metal diaphragm (18, 18′, 18″) is disposed over a fluid pressure receiving recess (16d, 16d′) formed in a bottom wall of a hexport housing (16, 16′) and hermetically attached thereto. A capacitive sensor element (12) having a pressure sensitive surface (12b) is disposed in the housing with the pressure sensitive surface placed against the metal diaphragm with a plastic intermediate layer (20, 20′, 20″, 20′″) disposed between the metal diaphragm and the sensor element to minimize hysteresis and output error. The metal diaphragm and plastic layers are shown to be flat members in certain embodiments (18, 18′ and 20, 20″) and corrugated in another embodiment (18″, 20″).

  • Patent number: 5628100
    Abstract: An acceleration sensor is shown having a substrate (16, 16', 16", 16'") on which a capacitor detect plate (24) and source plate mounting portion (28c) are disposed. An electrically conductive blade member (40, 44) having an attachment portion (40a, 44h), a source plate portion (40i, 44a) and integrally attached beams (40b, 40c; 44b) extending along opposite sides of the blade member is mounted on the substrate by welding the attachment portion to a mounting element (36, 36', 36", 36'") which is closely received in a bore (32, 32', 32", 32'") formed through the substrate at the source plate mounting portion. The mounting element or the bore is formed with a surface suitable for forming an interference fit and for making electrical engagement with a conductive layer received in the bore. The mounting element has one end (36b, 36b', 36b") which extends above the top surface (26, 26") an adjustable selected amount(s) to provide desired spacing between the source plate portion and the detect plate.

  • Patent number: 5402099
    Abstract: A snap acting control member (10, 10b) having high actuating temperatures comprises metal layers metallurgically bonded together with a low expansion (12) and a relatively high expansion layer (14) each having similar moduli of elasticity and the low expansion layer being formed of a precipitation hardenable stainless steel so that after forming into a dished shaped configuration to make the member snap acting the low expansion layer is heat treated to increase the strength. The control member can be used solely to sense temperature or it can be used as an electrical current carrying member. When used in the latter manner, the electrical resistivity of the member can be adjusted by interposing a selected layer (16) between layers (12) and (14) to thereby increase or decrease the resistivity of the member (10b) depending on the particular metal chosen for the interlayer.
