  • Publication number: 20240077781
    Abstract: Conventional high performance computer connections are electron-based systems, which require the memory packages to be as close as mechanically possible to the computation engine. Low power and high bandwidth communication, e.g. photonic, links can drastically change the architecture of high-performance computers by eliminating the bottlenecks in communication and augment existing memory systems to allow them to be both high capacity and high bandwidth simultaneously.

  • Publication number: 20240070933
    Abstract: A method for correcting location of a virtual target in a patient during a live procedure comprises segmenting the organ and the real target from an initial pre-procedure image data set; receiving a live procedure image data set of the patient including the organ and the real target and camera tracking information; registering the initial pre-procedure image data set and the live image data set; determining a candidate location of a virtual target for the real target based on the initial registration; generating a first image at a first view angle showing the virtual target and the real target; adjusting the candidate location of the virtual target to match the actual location of the real target in the first image; and computing a corrected location for the virtual target based on the adjusting step. Related systems are disclosed.

  • Publication number: 20240068275
    Abstract: A vertical door latch assembly includes a housing and a bolt movably attached to the housing having a catch portion. A drive motor is located within the housing and is configured to selectively move a lock assembly between a locked position preventing movement of the bolt and an unlocked position allowing movement of the bolt. A battery assembly is removable from the housing when the lock assembly is in first position and fixed to the housing when the lock assembly is in a second position. A controller is in electrical communication with the drive motor and is configured to direct the actuator lock assembly between the locked position and the unlocked position.

  • Publication number: 20210149851
    Abstract: A system for generating a storage-efficient data structure representing a plurality of inter-related data tables and adapted for use in data processing. The system configured to receive input data and generate a graph database having edges and vertices. Each inter-related data table of a plurality of inter-related data tables is received as input data and defines a corresponding vertex of the vertices. The edges defining pairwise relationships between the vertices based on one or more common elements of a corresponding pair of data tables. A reduced graph database is generated, as well as its connected-components. A partition defined by an equivalence relation on the graph database is used to generate the reduced graph database. Each set of the plurality of sets of the partition is represented by a single vertex of the corresponding set. An output data structure indicative of the connected-components, or additionally or alternatively, the irreducible generators, is generated.
