Abstract: A video monitoring system can include multiple collectors to receive video beacon data from multiple video monitoring interface modules. At least one beacon stream is connected to receive data from multiple collectors. A processing module receives the beacon stream and provides a real-time event stream used for real-time data analysis and a video view stream used for long-term data analysis.

Abstract: Thermal barrier assemblies are provided for traction battery packs. An exemplary thermal barrier assembly may be configured to block or even prevent thermal energy associated with a battery thermal event from moving from cell-to-cell, compartment-to-compartment, and/or cell stack-to-cell stack within the traction battery pack. The thermal barrier assembly may include features such as a protective housing and a thermal insulating barrier provided within the protection housing. The protecting housing may be made of a metallic, ceramic, or polymeric material, for example. The thermal insulating barrier may include an aerogel, a foam, or an inorganic paper, for example.

Abstract: A fiber-based master optical power amplifier (MOPA) is configured to utilize a pump source that operates in pulse mode with the arrival time of the pump pulses coordinated with the arrival time of the input pulses. The width of the pump pulses is also controlled, thus providing a mechanism for controlling both the amount of pump energy injected into the fiber amplifier, as well as the overlap in time between the pump pulse and the seed pulse. As the pulse repetition interval (PRI) of the input seed pulse changes, the timing of the pump pulses and their width are also changed so that a “constant gain” environment is created within the amplifying medium, providing an essentially constant energy output pulse, regardless of differences in ASE generated during different PRIs.

Abstract: An apparatus includes a housing including a bore and a housing groove within the bore and located on an inner surface of the housing; and a coil spring located within the housing and mounted within the housing groove, wherein the housing groove has a non-uniform radius such that the coil spring defines zones of relative low contact force and zones of relative high contact force.

Abstract: A method of producing a composite article is disclosed that includes generating composite plies from a low tack composite prepreg material, connecting, by an ultrasonic welding device, two or more of the composite plies by increasing their tackiness to form a composite stack, and forming, by a compression molding device, a composite article from the composite stack.

Abstract: Embodiments of the invention are related to medical devices filled with a liquid composition, amongst other things. In an embodiment, the invention includes a hermetically sealed housing defining an interior volume, a component module disposed within the interior volume, the component module comprising a circuit board, the component module displacing a portion of the interior volume. A liquid composition can be disposed within the housing, the liquid composition filling at least 80% of the interior volume not displaced by the component module. Other embodiments are also included herein.

Abstract: An assembly for compression molding includes an insert housing defining a plurality of apertures having stop surfaces. The assembly includes a plurality of inserts disposed within the apertures and in engagement with the stop surfaces. The assembly further includes a plurality of gas springs in biased engagement with the inserts. Individual gas springs of the plurality of gas springs are adapted to independently compress under load to permit independent movement of individual inserts within the apertures relative to the insert housing.

Abstract: An OTDR system utilizes a laser source that is turned “on” and kept powered until its light reaches the end of the fiber span being measured (i.e., until the fiber span is fully illuminated). At any point in time after the fiber is fully illuminated, the laser source can be turned “off”. The return (reflected and backscattered) signal is directed into a photodetector of the OTDR, and is measured from the point in time when the fiber span starts to be illuminated. The measurements are made by sampling the return signal at predetermined time intervals—defined as the sampling rate. The created power samples are then subjected to post-processing in the form of a differentiation operation to create a conventional OTDR trace from the collected data.

Abstract: In one embodiment, a fiber treatment system includes a rotatable nubbed roller including an axis of rotation, a surface, and a number of spaced apart nubs projecting away from the surface, the number of spaced apart nubs imparting a number of spaced apart openings in a fiber tow. In another embodiment, the fiber treatment system further includes an optionally rotatable spreader roller for flattening the fiber tow. In yet another embodiment, the loosened, but still continuous fiber tow is chopped by a downstream chopper to form short fibers with reduced tow sizes.

Abstract: A vented set screw is used to secure a connection between an implantable medical device and an implantable lead. The vented set screw includes one or more venting channels that allow liquid and/or gas to flow out of the implantable medical device when the implantable lead is being inserted into the implantable medical device and secured during an implantation procedure. This prevents pressure from building up at the connection, thereby ensuring proper performance of sensing and/or therapy delivery functions of the implantable medical device.

The extruded material may be formed as blanks for use in compression molding or may be introduced into an injection chamber for use in injection molding. The method may be used to form molded articles having a plurality of regions having different fiber contents.
