    摘要: A pressure transducer having a redundant fluid pressure sensor can be used to determine if the pressure transducer needs to be recalibrated. The pressure transducer comprises a fluid pressure sensor for measuring differential pressure. The fluid pressure sensor includes a pair of substantially identical pressure sensors for providing a variable electrical output as a function of a differential fluid pressure and a reference sensor for providing an electrical output independent of the differential fluid pressure. A conditioning circuit is provided for generating a frequency-based signal whose frequency is a function of the electrical output for each fluid pressure sensor. The electrical output of the first and second pressure sensors can be compared to determine whether the pressure transducer needs to be calibrated. In one embodiment, the pressure sensors comprise variable capacitors. The first and second capacitors each have one fixed plate and one movable plate responsive to differential fluid pressure across the movable plate. The reference capacitor has two fixed plates. The first variable, second variable, and reference capacitors are all located in proximity to one another and in communication with the differential fluid pressure. The pressure transducer also includes a switching network connected to the capacitors for selectable connecting at least one of the capacitors to an electronic circuit.

    摘要: A novel flashlight assembly that includes an interface integrated into the housing thereof to facilitate mounting of the flashlight to the dovetail rail on a modern combat weapon. The outer body of the flashlight includes a head mounted to a flashlight body at one end and a tapered tail extending outwardly at the other end of the body. Further, the flashlight includes a clamping interface that is a seamless and integrated feature of the outer housing of the flashlight itself for interfacing the flashlight with a firearm. The operational modes of the flashlight are controlled by a single push button and a selector switch. To facilitate a highly compact design the flashlight employs two circuitry arrangements positioned remote from one another and in communication with one another via a single conductive trace to operate at a first signal frequency or a second signal frequency.

    摘要: The cove base molding strip includes a body including a planar portion having a front surface and a rear surface and a curved portion having a concave surface continuous with the front surface and a convex surface continuous with the rear surface. The rear surface includes at least a first channel. A cove anchor projects from the convex surface, and the intersection of the front surface and the rear surface define a rounded tip that projects from the planar portion.
