Abstract: A capacitive pressure transducer is disclosed in which a sensing diaphragm bearing an electrode is mounted to flex in response to applied fluid pressure relative to a reference member having an opposed electrode. A thin film or layer of dielectric material such as glass covers the reference member electrode and has formed therein a concavity matching the flexed curvature of the sensing diaphragm at its limit position. The dielectric layer has a high compressive strength and substantially enhances linearity by providing a substantially higher capacitance than the equivalent fluid-filled space. The transducer is retained within a transducer assembly under compressive preload, the assembly further including thermal strain relief means. Also disclosed are methods of making the transducer, which methods include thick film screen deposition techniques for forming concavities having preselected contours in the dielectric layer.

Abstract: A connector for use in effecting optical signal transmissive connections between the ends of optical fibers is provided employing at least three surfaces defining a fiber-receiving channel. The walls defining the channel surfaces are resiliently movable whereby application of compressive forces to the walls results in shrinkage of the interior channel defined thereby. The channel walls may thus align fiber ends disposed therein along a longitudinal axis.

Abstract: A signal generating device comprising a bistable magnetic device which alters its magnetic state when the density of magnetic flux to which it is subject passes through a predetermined value, and detecting means providing an output signal responsive to a change in magnetic state of said bistable device. A conducting means for magnetic flux comprises a first portion providing a first path of high permeability and a second portion, and has the bistable device connected between the first and second portions for conducting therebetween and being subjected to the conducted magnetic flux. The second portion provides second and third paths through the bistable device, each having a respectively alterable permeance for varying in an opposite relationship the respective reluctance of the second and third paths of the conducting means and the density and sense of magnetic flux to which the bistable device is subject.

Abstract: Method and means for coupling an elongated magnetic device such as a "Wiegand" wire to a magnetic circuit comprising the steps of shaping the ends of an elongated magnetic device to provide a high ratio of surface area to volume and a contact surface at each end, and connecting the contact surface of each end of said magnetic device to a conforming portion of a respective one of a pair of spaced ends of a flux conductive means to provide a magnetic path through said conductive means and magnetic device. The ends of the magnetic device are shaped by being compressed to provide flat surfaces on opposite sides and are connected by electric welding, clamping, soldering or adhering same with the flux conductive means. In one form the conductive means is provided with a shunt path for magnetic flux for reducing the reluctance of the coupling means, and controlling the proportion of magnetic flux passing through the elongated magnetic device.
