Abstract: The disclosure provides a thermally stable melt processable thermoset polymer composition including at least one melt processable thermoset polymer, such as an epoxy, and at least one reinforcing filler, such as carbon nanotubes. Such compositions when 3D printed, exhibit improved Z-layer adhesion and modulus at melt temperature, a common related additive manufacturing problem, as compared to thermoset polymers without reinforcing filler and more conventional thermoplastic resin systems. Subsequent actinic cure of such compositions irreversibly and permanently cures the material thereby making it no longer melt processable.

Abstract: A battery exhaust vent includes an expanded metal filter which acts as a heat sink to cool an overheating battery. The exhaust vent acts as a particulate filter and flame arrestor which reduces flames and particulate slag projectiles from being expelled outside a battery housing. Directional Flow Expanded Metal (DFEM) and Variable Expanded Metal (VEM) are utilized for their directional fins and associated plethora of openings offset in overlapping layers to create a cyclone effect for gases or particles passing through the filter. The fins and holes are offset from layer to layer within a multi-layer filter construction and are designed to immediately change the direction of the flames and burning particles relative to the input flame flow direction. The vent may include an elastomeric umbrella valve which seals the vent from external airflow but allows quick venting for internal gas pressure during a runaway event or excessive heating.

Abstract: A client device accesses a video input stream from an intermediate device for display. The client device analyzes the video input stream to determine that the video input stream matches a template corresponding to a screen portion. Based on the video input stream matching the template, a video output stream is generated and caused to be presented on a display. In some example embodiments, the analysis is performed while the client device is replacing video content received from a content source via the intermediate device. For example, commercials transmitted from a national content provider to a smart TV via a set-top box may be replaced with targeted commercials. During the replacement, menus generated by the set-top box may be detected and the replacement video altered by the smart TV to include the menus.
