    Abstract: A pressure sensor (58) includes a structure (54) that deforms in response to an applied pressure (P). A light source (60) is directed at the structure. This provides a reflection from the structure. A sensor (62) is arranged to sense the reflection and provide an output (66) related to the applied pressure (P).

    Abstract: A tunable Fabry Perot filter (TFPF) uses the hybrid integration of MEMS and micro-optics. The mirrors forming the TFPF are actively aligned to provide a high finesse TFPF. One of the reflectors is mounted to a flexible member, for example a beam member fixed at both ends. The flexible member is deflectable in a direction parallel to the axis of the TFPF so as to adjust the gap between the reflectors, thus tuning the TFPF. One or both of the mirrors may be deposited on the end of an optical fiber.

    Abstract: A process device (202) includes a fluid disruption generation element (210) to generate a fluid disruption within process fluid flowing through a pipe associated with an industrial process and a process variable sensor coupled to the disruption generation element (210) to measure a process parameter. The process device (202) further includes a power generation element (212) adapted to generate an electrical output signal in response to the fluid disruption and a power storage component (226) coupled to the power generation element (212). The power storage component (226) is adapted to accumulate a charge based on the electrical output signal.

    Abstract: A variable optical attenuator has a first movable waveguide support and a second waveguide support that include first and second waveguides, respectively, such that the first and second waveguides are aligned for propagating an optical energy. An electrically driven actuator positions the movable waveguide support for coupled, optical misalignment relative to the second support to achieve a desired optical attenuation value. The movable waveguide support may be in a cantilevered configuration in which a distal end extends over a surface having an electrode. In this example, applying a drive signal to the electrode deflects the movable support such that the signal coupled between the first waveguide to the second waveguide is attenuated. The drive signal may be set to achieve a desired value for an electrical parameter that varies with the position of the movable waveguide support. In some examples, the drive signal is set to achieve a desired capacitance or voltage difference between the movable waveguide support and the electrode.
