A sensor is disclosed herein. The sensor includes a fiber operable to communicate a light wave. The sensor also includes at least first and second Fiber Bragg Gratings disposed along the fiber. The sensor also includes a structure operable to be deformed in a plane of deformation. The at least first and second Fiber Bragg Gratings are disposed on opposite sides of the structure in the plane of deformation. The sensor also includes an interrogation unit operable to receive first and second signals corresponding to first and second wavelengths from the at least first and second Fiber Bragg Gratings. The first signal is associated with the first Fiber Bragg Grating and the second signal is associated with the second Fiber Bragg Grating. The sensor also includes a processor operable to derive a difference between the wavelengths of the first and second signals and compare the difference with data correlating wavelength differences to extents of deformation of the structure to yield a current extent of deformation.

Position sensor using Fiber Bragg Gratings to measure axial and rotational movement

A device and method for the removal of a metal-sheath layer from a metal-sheathed structure using capacitive discharge in conjunction with step-up and step-down transformers to create a low voltage, high current pulse to remove a selected portion of the metal-sheath layer from the metal-sheathed structure.

Position sensor using fiber bragg gratings to measure axial and rotational movement

A measurement device including a fastener for use in attaching a first member to a second member, in which the fastener has an aperture extending through a length of the fastener, and a first optical fiber located within the aperture, in which the first optical fiber includes at least one fiber Bragg grating sensor. At least a portion of the first optical fiber can be secured within the aperture. A first end of the first optical fiber can be connected to an associated first optical connector and a second end of the first optical fiber can be connected to an associated second optical connector.

Smart fastener and smart insert for a fastener using fiber Bragg gratings to measure strain and temperature

A gear pump is provided with a pair of rotatable pumping gears for pumping fluid between inlet and outlet ports formed in a gear pump housing, wherein a portion of the housing is adapted for positional adjustment to reduce internal operating clearances and thereby regenerate pump output performance without requiring pump disassembly or rebuilding.
