Abstract: Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for simulating heat transfer in additive manufacturing. Implementations disclosed herein convert a model of an object into a node representation of the object, and generate an adjacency matrix of the object based on the node representation. For each layer of nodes in the node representation, implementations apply a simulated heat to the layer of nodes, and estimating a diffusion of heat to other nodes based on the adjacency matrix. Implementations generate a representation of an estimated heat distribution within the object.

Abstract: An internal combustion engine-based system includes an internal combustion engine. The internal combustion engine-based system includes an engine interrupt connected to the engine. The engine interrupt is configured to selectively stop the operation of the engine. The internal combustion engine-based system includes a controller in communication with the engine interrupt. The internal combustion engine-based system includes a carbon monoxide detector in communication with the controller. The controller uses the engine interrupt to stop the operation of the engine when the carbon monoxide detector provides the controller with signals that are representative of a carbon monoxide level proximate the internal combustion engine that together form a trend of building carbon monoxide amounts over a set time interval.

Abstract: An entity may generate generic notifications for transmittal to a plurality of customers. One of the notifications may not be properly customized for a customer to whom the notification is scheduled for deployment. A system is provided that generates and refines generic notifications using artificial intelligence (“AI”). The system may include an application server running an AI engine for periodically monitoring, at a given point in time, historical customer data relating to less than a predetermined number of customers to ensure reduced, relative to a predetermined baseline, processing usage. The AI engine may determine, during the monitoring, that notifications transmitted by the platform to one of the customers have failed to elicit a positive response from the customer. The determination may prompt the AI engine to put the generic notification on hold for the customer and to perform additional steps to alter the generic notification to a targeted notification.

Abstract: A portable generator system is disclosed which includes a portable generator and an auxiliary fuel tank. The auxiliary fuel tank may be mounted to and removed from the portable generator without tools. A fuel connector between the auxiliary fuel tank and the portable generator includes a male fitting and a female fitting. The male fitting engages the female fitting without tools and aids in aligning the auxiliary fuel tank with the portable generator.

Abstract: A web-guiding system for guiding a web of media travelling from upstream to downstream along a transport path in an in-track direction, including a web-guiding structure and a vacuum system. The web-guiding structure includes an exterior surface having a pattern of recesses formed into the exterior surface, wherein the web of media travels past the web-guiding structure with a first side of the web of media contacting at least some non-recessed portions of the exterior surface of the web-guiding structure. The vacuum system is positioned such that the web of media passes between the web-guiding structure and the vacuum system, the vacuum system being adapted to provide a vacuum force to pull the second side of the web of media toward the vacuum system, thereby lifting portions of the web of media overlying the recesses away from the exterior surface of the web-guiding structure.
