Abstract: A fire resistant corrugated coaxial cable is described that employs a high-temperature, insulating alkaline earth silicate (AES) wool dielectric. The AES wool dielectric is devoid of water as a constituent. The AES wool may be survivable under conditions of high heat, such as temperatures specified by common fire test standards (e.g., 1850° F./1010° C. for two hours). The cable is configured to maintain a relatively coaxial relation between a center conductor and an outer conductor even under aforementioned fire tests. A layer of ceramifiable silicone rubber or refractory fiber wrap can surround the outer conductor and continues to insulate it from the outside if a low-smoke zero-halogen (LSZH) jacket burns away.

Abstract: Embodiments provide systems, methods, and computer storage media for prediction and computation of electronic shopping carts. In an example embodiment, for each interaction between an e-shopper and an e-commerce application, one or more predicted electronic shopping carts that represent a combination of items the e-shopper is likely to purchase are generated based on current items in the e-shopper's electronic shopping cart and recent interactions with the e-shopper. For some or all of the predicted electronic shopping carts (e.g., those with top predicted confidence levels), corresponding shopping cart computations (e.g., identifying application promotions, determining a price total for the items in the predicted shopping cart) are executed and cached prior to the e-shopping adding the predicted items. As such, a page configured to visualize the predicted electronic shopping cart with a value retrieved from the cached shopping cart computations (e.g.

Abstract: A method for capturing real-time motion data events from a remotely deployed far edge compute node on a remote asset, such as a racing vehicle, allows for real-time motion simulation of a racing experience. In the method, incoming audio and video data are received from the far edge compute mode, along with incoming motion data. The motion data is imbedded within data frames of the audio/video to create distributable content.

Abstract: A method is provided for electrically conductively connecting a contact part to a conductor having a multiplicity of individual wires includes inserting the conductor into a cavity in the contact part and lowering a tool for friction stir welding onto the contact part. The tool for friction stir welding is moved on the contact part in a plane, thus giving rise to a planar cohesive connection between the contact part and the conductor. In this way, a direct cohesive connection of a stranded conductor and a contact part is produced without the need for an additional part such as a sleeve, for example, to prevent the stranded conductor from “sticking out”.

Abstract: The present invention relates to a method of improving the corrosion resistance of a metal substrate surface using an oxygen reduction catalyst, which may improve the corrosion resistance of the metal substrate surface by coating the metal substrate surface with the oxygen reduction catalyst so that the metal substrate surface is changed to a passive state through the action of the oxygen reduction catalyst in an environment in which a stable oxide layer is not spontaneously formed on the metal substrate surface. The present invention has an advantage in that it can dramatically improve the corrosion resistance of the metal substrate under a corrosive environment by allowing a recoverable oxide layer to be formed on the metal substrate surface through the action of the oxygen reduction catalyst, applied to the surface, even in an environment in which an oxide layer is not spontaneously formed on the metal substrate.
