Reverse forwarding information base enforcement
In exemplary embodiments of the present invention, a router determines whether or not to establish a stateful routing session based on the suitability of one or more candidate return path interfaces.

Techniques and mechanisms for compressing the size of SIDs to be smaller than a complete IPv6 address (or “micro SIDs”), and scaling micro SIDs across a multi-domain environment using micro SID-domain-blocks.

SuCCoR: a super critical cooling regulator to mitigate heating of batteries and other devices
Batteries and other devices heat during operation and must be cooled to optimal temperatures. Our SuCCoR method differs from the previous thermal management systems by keeping batteries and devices continuously immersed in a coolant bath kept in a sealed enclosure at its supercritical fluid (SCF) and/or a neighboring thermodynamic state with superb heat conducting properties. While many previous inventions circulated coolants, and some kept devices sealed in a fluid, our invention differs by its use of SCF coolants with no distinct liquid and gas phases. Such a single-phase coolant prevents abrupt loss of cooling due to “vapor lock” formation. Also, using an outer jacketed vessel and a network of heat conducting pipes containing high thermal conductivity and high heat capacity coolants, and deploying cooling fins will enhance efficiency and accelerate heat removal. Our system avoids complex pumps to circulate the coolants, and is lighter and cheaper. |

The server apparatus manages, for each of a plurality of real spaces, information for identifying the real space and anchor information for defining a superimposition position of the virtual space in the real space and, in a case where an acquisition request for anchor information corresponding to a first real space is received from the terminal, transmits response information including anchor information corresponding to the first real space and anchor information corresponding to a second real space adjacent to the first real space to the terminal. The terminal stores the response information received from the server apparatus and, in a case where the terminal is placed into the second real space, displays an image representing a mixed reality space based on anchor information corresponding to the second real space. |

Adaptive rate shading using texture atlas
In one embodiment, a method includes a server generating first shading information for visible portions of objects relative to a first viewpoint, storing the first shading information in a texture atlas, and sending the texture atlas to a client device. The method also includes determining a first subset of the visible portions of the objects for which shading information is to be re-generated and a second subset for which elements of the first shading information are to be reused, generating second shading information for the first subset relative to a second viewpoint, updating the texture atlas to include the second shading information for the first subset and the elements of the first shading information for the second subset, and sending the updated texture atlas to the client device. The updated texture atlas is configured for rendering images of the visible portions of the objects from multiple viewpoints. |

Intersection testing for ray tracing
A system and method for performing intersection testing of rays in a ray tracing system. The ray tracing system uses a hierarchical acceleration structure comprising a plurality of nodes, each identifying one or more elements able to be intersected by a ray. The system iteratively obtains ray requests, each of which identifies a ray and a node against which the ray is to be tested, and performs intersection testing based on the ray requests. The number of ray requests obtained in each iteration reduces responsive to an amount of memory occupied by information relating to the rays (undergoing intersection testing) increasing. |

Apparatus and method for cross-instance front-to-back traversal for ray tracing heavily-instanced scenes
Apparatus and method for programmable ray tracing with hardware acceleration on a graphics processor. For example, one embodiment of a graphics processor comprises shader execution circuitry to execute a plurality of programmable ray tracing shaders. The shader execution circuitry includes a plurality of single instruction multiple data (SIMD) execution units. Sorting circuitry regroups data associated with one or more of the programmable ray tracing shaders to increase occupancy for SIMD operations performed by the SIMD execution units; and fixed-function intersection circuitry coupled to the shader execution circuitry detects intersections between rays and bounding volume hierarchies (BVHs) and/or objects contained therein and to provide results indicating the intersections to the sorting circuitry. |
