Abstract: An apparatus includes a cassette configured to hold optical fiber comprising one or more optical sensors. The cassette comprises a spool configured to one or more of extract and retract the optical fiber from the cassette. A fiber monitor is coupled to the cassette. The fiber monitor is configured to monitor at least one parameter of the optical fiber as the optical fiber is extracted from the cassette.

Abstract: An apparatus has a chassis having a base. A first wall extends substantially perpendicularly from the base at a first edge of the base. The first wall is configured to be a first attachment point for an optical cable comprising one or more optical sensors. An opposing second wall extends substantially perpendicularly from the base at a second edge of the base. A mobile attachment point is configured to be a second attachment point for the optical cable. A spring is coupled to the second wall and the mobile attachment point. The spring is configured to provide a specified force as the mobile attachment point moves.

Abstract: An apparatus includes one or more stamps configured to install an optical fiber on a surface of a structure. Each stamp includes a backing. A first adhesive is disposed on one or more first regions of the backing and is configured to provide a temporary bond between the optical fiber and the surface. A second adhesive is disposed on at least a second region of the backing and is configured to provide a substantially permanent bond between the optical fiber and the surface. A liner is removably adhered to the first adhesive.

Abstract: A system for evaluating a high voltage asset (HV asset) comprises a PD detector disposed in the HV asset. The PD detector comprises an electrical coupler configured to couple electrical disturbances indicative of a partial discharge from a high voltage conductor of the HV asset to an electrical-to-optical converter. The electrical-to-optical converter comprises a light emitter, and is configured to convert the electrical disturbances to a light signal. An optical power receiver is disposed in the high voltage asset and coupled to the PD detector. The optical power receiver is configured to receive optical power from an external optical power source via a non-conducting optical fiber arrangement. The electrical-to-optical converter is configured to communicate the light signal indicative of the partial discharge to an electronic device external of high voltage asset via the non-conducting optical fiber arrangement.

Abstract: An analyzing system includes a fluidic stream that guides an analyte in a detection area where the analyte emits or transmits light. One or more polarizing elements polarize the light into respective two or more different polarization components. One or more optical detectors receive the respective two or more polarization components and generate respective at least two signals in response. A processor is coupled to the optical detectors and configured to determine the polarization status of the light from the object based on the signals.

Abstract: Formation of a multi-colored image in thermochromic material involves controlling operation of first, second, and third heat sources. The first heat source heats pixels of the thermochromic material to activate the pixels. The second and third heat sources are selectively controlled to heat different sets of pixels using neither, one, or both of the second and third heat sources.

Abstract: An analyzing system includes a detection area with a transparent window past which an analyte moves and emits or transmits light. One or more polarizing elements receive and polarize the light into respective two or more different polarization components. One or more optical detectors receive the respective two or more polarization components and generate respective at least two signals in response. A processor is coupled to the optical detectors and configured to determine a polarization status of the light from the analyte based on the at least two signals.

Abstract: A cassette for optical fiber includes one or more optical sensors. The cassette has a spool for handling optical fiber. An adjustable shaft is disposed such that the spool is configured to rotate about the adjustable shaft. The adjustable shaft is configured to handle spools having different diameters. A spool controller is coupled to the adjustable shaft and configured to rotate the adjustable shaft to perform one or more of extract and retract the optical fiber. One or more bushings are disposed proximate the spool and are configured to prevent the optical fiber from jumping off the spool.
