The air guide duct also has at least one air outlet opening into at least one of the front wheel wells such that incoming air from the front end of the motor vehicle is guided into at least one of the front wheel wells.

Abstract: Core particles produced in situ or introduced as preformed core particles are coated with a layer of carbon. Non-carbon as well as some carbon-based core materials can be utilized. The resulting carbon coated particles can find applications in rubber products, for instance as reinforcement for tire components.

Abstract: Methods to prepare elastomer compounds are described that include dry mixing at least one additive to an elastomer composite masterbatch at low temperatures over a shortened mixing cycle with reduced energy consumption. The elastomer composite masterbatch is produced in a liquid masterbatch process. The resulting elastomer compounds are further described as well as property improvements that can be achieved.

Abstract: After finding the shortest conductive signal return-current path for each signal, the invention assesses whether each conductive return-current path is adequate. The method analyzes each shortest conductive signal return-current path and determines if a significant portion of the signal return current flows as displacement current rather than following the conductive current path. A significant displacement current flows when the length of the conductive return-current path that diverges from a signal net is more than a previously defined limit based on the signal transition time. Further, a significant displacement current flows when the overall length of the signal differs from the overall length of the conductive return-current path by more than a previously defined limit based on the signal transition time.

Abstract: A system, method and media for locating and defining process sensitive sites isolated to specific geometries or shape configurations within chip design data. Once a systemic process sensitive site is identified, a 3D design checking deck is coded and executed through a design checker on physical design data. Target match shapes are produced and embedded back into the design data. Pictures, maps and coordinates of process sensitive sites are produced and sent to a website library for reference.

Abstract: An apparatus measures a fluid level in a container. A light source emits a light beam. A light sensor can sense the light beam. An optical conduit is arranged in a container for holding fluid. The optical conduit is arranged between the light source and the light sensor along a path of the light beam, such that at least one part of the light beam passes through the optical conduit, and at least an other part of the light beam passes through the fluid when the container holds the fluid. The sensor senses the light beam when a level of the fluid coincides with the one part of the light beam passing through the optical conduit, and the sensor does not sense the light beam when the level of the fluid coincides with the other part of the light beam passing through the fluid due to internal reflection at the fluid level.

Abstract: A method for quickly tracing minimum-length conductive return paths through an electronic structure utilizes a raster based (cellular) memory model comprising individual grids for each layer of the structure. Each grid comprises a reduced resolution N×M cell representation of the conductive structures on that layer. Cellular methodologies are then used to determine, for each signal net, the shortest return path. This information can then be used for various purposes, including determining if the return path is sufficient to ensure adequate signal integrity.

Abstract: A ceramic electron beam accelerator is disclosed finding particularly efficacious uses in X-ray electronic circuit imaging and testing applications. The ceramic stage design eliminates the need for placing metal reinforcements between adjoining stages of the accelerator, thereby increasing the accelerator's mechanical robustness and reliability, while also reducing manufacturing costs.

Abstract: A method of performing latch up check on an integrated circuit (IC) design that comprises rasterizing a conductor region shape and contact shapes and iteratively expanding the contact shapes within the conductor region shape using a cellular algorithm. Direction values for contact cells can be used to limit the number of neighboring cells which must be explored. In every fourth iteration of the expansion process, corner cells may not be expanded. Reachable areas outside of conductors can also be explored.
