  • Patent number: 12002145
    Abstract: Apparatus and method for efficient graphics processing including ray tracing. For example, one embodiment of a graphics processor comprises: execution hardware logic to execute graphics commands and render images; an interface to couple functional units of the execution hardware logic to a tiled resource; and a tiled resource manager to manage access by the functional units to the tiled resource, a functional unit of the execution hardware logic to generate a request with a hash identifier (ID) to request access to a portion of the tiled resource, wherein the tiled resource manager is to determine whether a portion of the tiled resource identified by the hash ID exists, and if not, to allocate a new portion of the tiled resource and associate the new portion with the hash ID.

  • Publication number: 20240173136
    Abstract: A modular acetabular cup assembly includes an acetabular cup, and a liner seated in the cup. The cup includes an end face, an apex opposite the end face, and a central axis extending between the apex and a center point of the end face. The liner includes an articular surface having a center of rotation which defines a pivot point of the acetabular cup assembly. In certain embodiments, the pivot point is laterally offset from the center point such that the end face is located between the pivot point and the apex.

  • Patent number: 11962009
    Abstract: A high-performance electrochemically active sodium molten salt catholyte enables a dramatic reduction in molten sodium battery operating temperature from near 300° C. to less than 120° C. As an example, stable electrochemical cycling was demonstrated in a high voltage (3.65 V) sodium battery comprising a sodium iodide-gallium chloride (NaI—GaCl3) molten salt catholyte for over 8 months at 110° C. The combination of high voltage, stable cycling behavior, and practical current densities supported by a molten catholyte enables a new generation of transformative high performance, low temperature molten sodium batteries.

  • Publication number: 20220273449
    Abstract: An acetabular cage or device is disclosed. In one embodiment, the acetabular cage includes a cup portion configured for implantation in an acetabulum and a flange extending from the cup portion. The flange including a first, bone contacting surface configured to face bony tissue surrounding the acetabulum when the cup portion is implanted into the acetabulum and a second, top surface opposite the first surface. The flange includes a flexible portion and a fixation portion, the fixation portion including one or more fixation features configured to facilitate fixation of the flange to the bony tissue surrounding the acetabulum. The flexible portion is arranged and configured to enable the flange, and hence the fixation portion, to move relative to the cup portion to facilitate placement of the flange relative to the bony tissue.

  • Patent number: 7659017
    Abstract: For various reasons, it can be desirable to subject fuel cells to drying procedures. In solid polymer electrolyte fuel cells for instance, drying may be carried out prior to storing at below freezing temperatures, or to recover cell performance lost following freeze/thaw events. An improved drying method involves drying the cell uniformly throughout. That is, the drying power over the length of the fuel cell is adjusted to be essentially uniform. This can be accomplished by using an appropriate set of operating conditions. The improved drying method can improve the lifetime of the fuel cell.

  • Publication number: 20040221169
    Abstract: Prior to execution of application software by a computer terminal, the computer terminal is connected to an electronic key and initiates a registration procedure with a remote server so as to obtain a software registration code that is stored in each of the computer terminal and the electronic key. Thereafter, it is only when the computer terminal is connected to the electronic key, and when the software registration code stored in the computer terminal matches that stored in the electronic key will subsequent execution of the application software by the computer terminal be enabled. The method as such can discourage software piracy.
