  • Patent number: 12266083
    Abstract: A method of filtering a target pixel in an image forms, for a kernel of pixels comprising the target pixel and its neighbouring pixels, a data model to model pixel values within the kernel; calculates a weight for each pixel of the kernel comprising: (i) a geometric term dependent on a difference in position between that pixel and the target pixel; and (ii) a data term dependent on a difference between a pixel value of that pixel and its predicted pixel value according to the data model; and uses the calculated weights to form a filtered pixel value for the target pixel, e.g. by updating the data model with a weighted regression analysis technique using the calculated weights for the pixels of the kernel; and evaluating the updated data model at the target pixel position so as to form the filtered pixel value for the target pixel.

  • Publication number: 20250105356
    Abstract: An electrolyte solution includes a compound represented by Formula I: where m, n, k, and x are each independently selected from 1, 2, or 3; R11 and R12 are each independently selected from hydrogen, halogen, substituted or unsubstituted C1 to C3 alkyl, substituted or unsubstituted C2 to C4 alkenyl, substituted or unsubstituted C2 to C4 alkynyl, or substituted or unsubstituted C6 to C10 aryl, wherein when substituted, a substituent is independently selected from halogen. The multi-cyano (—CN) compound represented by Formula I is introduced into the electrolyte solution, so that the multi-cyano group can stabilize a transition metal in a positive active material and protect a positive electrode interface. The compound represented by Formula I can also be reduced at a negative electrode to protect a negative electrode interface and play a role in suppressing continuous decomposition of the electrolyte solution and suppressing gas production.

  • Patent number: 12260487
    Abstract: Ray tracing systems and methods for generating a hierarchical acceleration structure for intersection testing. Nodes of the hierarchical acceleration structure are determined, each of the nodes representing a region in a scene, the nodes being linked to form the hierarchical acceleration structure. Data is stored representing the hierarchical acceleration structure. The stored data comprises data defining the regions represented by a plurality of the nodes. At least one node is an implicitly represented node, wherein data defining a region represented by an implicitly represented node is not explicitly included as part of the stored data but can be inferred from the stored data. Also described are ray tracing systems and computer-implemented methods for performing intersection testing in which, based on conditions in the ray tracing system, a determination is made as to whether testing of one or more rays for intersection with a region represented by a particular node of a sub-tree is to be skipped.

  • Patent number: 12259822
    Abstract: A method of GPU virtualization comprises allocating each virtual machine (or operating system running on a VM) an identifier by the hypervisor and then this identifier is used to tag every transaction deriving from a GPU workload operating within a given VM context (i.e. every GPU transaction on the system bus which interconnects the CPU, GPU and other peripherals). Additionally, dedicated portions of a memory resource (which may be GPU registers or RAM) are provided for each VM and whilst each VM can only see their allocated portion of the memory, a microprocessor within the GPU can see all of the memory. Access control is achieved using root memory management units which are configured by the hypervisor and which map guest physical addresses to actual memory addresses based on the identifier associated with the transaction.
