    摘要： A transducer packaging assembly for use in a sensing unit subjected to high forces of acceleration includes a base having a cavity. A pressure sensitive semiconductor die is bonded to a large backplate having a shape so that it nestles into the cavity but is spaced from a surface of the cavity. A planar cover secured to the base has a hole larger than the die but smaller than the backplate, and thin wires extend from the die to electrical connections on the assembly. A viscous fluid fills a space between the backplate and the cavity, and a space between the backplate and the cover, and transmits a pressure to be measured to the pressure sensitive die. The viscous fluid has a sufficiently high viscosity to oppose movement of the backplate relative to the cavity while cushioning the pressure sensitive die and the backplate from forces of acceleration.

    摘要： An absolute pressure sensor subassembly includes a top cap bonded to a pressure sensor die and enclosing a reference vacuum. The subassembly is initially held in place within a housing by a vacuum or sublimeable solid adhesive while wire bonds from the subassembly to the housing leads are completed. A self-contained adhesive drop on the inner surface of the housing cover contacts the sensor subassembly when the cover is placed on the housing body and the sensor subassembly is supported by the adhesive drop.

    摘要： A recoil and muzzle blast dissipator may be attached to the barrel of a gun and may redirect propellant gasses. In one embodiment, a recoil and muzzle blast dissipater may include a body portion having an internal plenum and a plurality of vent slots, each vent slot having an aperture in communication with the internal plenum. Each successive vent slot may include an aperture that is larger in area than the aperture of the previous vent slot. An exterior tube may include a side port and may be arranged to overlay the body portion such that a portion of each vent slot is covered by the exterior tube, and a portion of each vent slot is in communication with the side port.
