Abstract: PROBLEM TO BE SOLVED: To avoid creep of a metalized layer on a flexible diaphragm. SOLUTION: This pressure sensor is provided with a dielectric part moving in a hollow near a condenser electrode fixed to a fitting frame. This diaphragm is supported on the frame and the frame surrounds the hollow. The diaphragm has an outer surface receiving the pressure and an inner surface facing to the hollow. The fixed condenser electrode senses the movement of the dielectric part positioned nearby and generates an electric output expressing the pressure.

Abstract: An optical medium having a cavity that defines a variable gap is provided. The optical medium is used in an optical sensor, laser, and variable frequency resonator, by way of example. The cavity is physically altered in response to changes in a measurable parameter like pressure, temperature, force, flow rate, and material composition. The optical medium is characterized in some embodiments by having a cavity disposed near or within a high Q optical resonator. The optical resonator can be formed by various structures or which Bragg reflector cavities, ring resonators, microdiscs, and microspheres are examples. The optical resonator is preferably coupled to a laser source. The altering of the cavity affects the resonance condition within the optical resonator and thereby the laser signal of the system. If the laser source is a mode locked laser, the repetition rate of the pulse train changes in response to changes in the measurable parameter. If the laser source is a CW source the frequency of the laser signal is dependent upon a measurable parameter.

Abstract: An optical switch for routing optical signals between optical fibers is shown. Signals are guided internally in an optically transparent substrate (206) by buried waveguides that are directly coupled to the optical fibers. These waveguides form a 3-dimensional optical routing structure internal to the substrate. Signals are coupled between adjacent waveguides by total internal reflection (TIR) at the internal reflection region (213). A moveable diffraction grating (208) is coupled to these optical signals at points of total internal reflection via evanescent coupling. This coupling causes a change in direction of the optical signal (202) and routes the signal to the desired waveguide (210). Known techniques can be used to form the waveguides (204, 210, 214) by writing them with a pulsed laser. Local heating causes a permanent increase in refractive index that forms a single mode waveguide structure. The resulting device has low losses and can be formed by low cost MEMs processes.

Abstract: An electromagnetic resonant sensor (800) has a dielectric sensor body (802) through which electromagnetic wave energy is propagated. The sensor body (802) has a cavity, with surfaces facing one another to define a gap (810) that varies as a function of a parameter to be measured. The resonant frequency of an electromagnetic standing wave (814) in the body (802) and the variable gap (810) changes as a function of the gap dimension.

Abstract: A process variable transmitter (50) which has a manual adjustment (60) for span and zero or the like. The adjustment (60) has a finer adjustment range where the output changes responsive to changes in the position of the adjustment. The adjustment has a coarse range where the transmitter output changes automatically as a function of time to provide coarser adjustment. An operator can move the adjustment back and forth between the adjustment ranges until a desired output value is observed. When adjustment is complete, the operator can manually select the desired transmitter output value and then a selection circuit (68) stores the setting in non-volatile memory (66, 13). After a setting is stored, the transmitter output is not sensitive to movement of the manual adjustment (60), but is instead controlled by the stored setting.
