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.

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 optical fiber mold device has a first portion that includes a base layer having a longitudinal feature configured to receive an optical fiber. At least one second portion is disposed over the base layer. The second portion has a center wall and front and back end walls. The center wall, the front end wall, and the back end wall form a mold cavity. At least one first hole is disposed in the mold cavity and is configured to allow mold material to enter the mold cavity. At least one second hole in the mold cavity is configured to allow air displaced by the mold material to exit the mold cavity.

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 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.
