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 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: A sensor system includes a sensor network comprising at least one optical fiber having one or more optical sensors. At least one of the optical sensors is arranged to sense vibration of an electrical device and to produce a time variation in light output in response to the vibration. A detector generates an electrical time domain signal in response to the time variation in light output. An analyzer acquires a snapshot frequency component signal which comprises one or more time varying signals of frequency components of the time domain signal over a data acquisition time period. The analyzer detects a condition of the electrical device based on the snapshot frequency component signal.

Abstract: Techniques for determining characteristics of a stream of jetted material in a three-dimensional (3D) printer are disclosed. An example system includes an ejector configured to release molten droplets along a jetting path from the ejector to a build platform. The system also includes a sensor positioned adjacent to the jetting path and configured to generate an electrical signal in response to light emanating from the molten droplets. The system also includes an optical mask positioned adjacent to the jetting path, the optical mask comprising a plurality of regions configured to modulate the electrical signal generated by the sensor as the molten droplets travel along the jetting path. The system also includes one or more processing devices to receive the electrical signal, analyze the electrical signal to identify one or more characteristics of the molten droplets, and control the 3D printer based on the one or more characteristics.

Abstract: A system includes a sensor network comprising at least two optical fibers coupled to a pavement. Each optical fiber includes one or more optical sensors installed a predetermined distance from one or more adjacent optical fibers. The one or more optical sensors are configured to produce a wavelength shift signal. A processor is configured to determine one or both of one or more attributes of one or more objects travelling on the pavement and a traffic condition of the pavement based on the wavelength shift signal. A transmitter is configured to transmit the one or more attributes to a predetermined location.
