  • Patent number: 8275940
    Abstract: A method is provided for optimization of the management of a server cache for dynamic pages, which may be consulted by client terminals with differing characteristics which requires the provision of discrete versions of a dynamic page in the cache. When a terminal requests a dynamic page, a verification step—for the presence of at least one version of the dynamic page in the cache is carried out, such that if the verification is positive the following complementary steps are carried out: procurement of a set of characteristics specific to the type of client terminal, determination of a subset of necessary characteristics from amongst the specific characteristics for the reproduction of the dynamic page on a client terminal, search, among the version(s) of the dynamic page in the cache for a suitable version using the subset of necessary characteristics and allocation of the suitable version to the client terminal.

  • Patent number: 8275756
    Abstract: Systems and methods enabling search of a repository for the location of data that is similar to input data, using a defined measure of similarity, in a time that is independent of the size of the repository and linear in a size of the input data, and a space that is proportional to a small fraction of the size of the repository. The similar data segments thus located are further analyzed to determine their common (identical) data sections, regardless of the order and position of the common data sections in the repository and input, and in a time that is linear in the segment size and in constant space.

  • Patent number: 8269768
    Abstract: Z-buffer rendering of three-dimensional scenes is made more efficient through a method for occlusion culling by which occluded geometry is removed prior to rasterization. The method uses hierarchical z-buffering to reduce the quantity of image and depth information that needs to be accessed. A separate culling stage in the graphics pipeline culls occluded geometry and passes visible geometry on to a rendering stage. The culling stage maintains its own z-pyramid in which z-values are stored at low precision (e.g., in 8 bits). The efficiency of hierarchical z-buffering is improved through hierarchical evaluation of line and plane equations.

    Abstract: A method for manufacturing a write head having write pole with a tapered upper surface to improve the channeling of magnetic flux to a pole tip of the write pole. The method includes depositing a first layer of magnetic material over a substrate. A CMP stop layer, image transfer layer and mask structure are deposited over the first magnetic layer, the mask structure being formed with an edge located a desired distance from an air bearing surface plane. An ion milling operation is performed to remove portions of the magnetic layer that are not protected by the mask structure, the ion milling being performed in a manner to form a tapered surface on the first magnetic layer. Then, a second magnetic layer is deposited over the first magnetic layer to form a tapered magnetic write pole.

  • Patent number: 8270109
    Abstract: In one embodiment, a magnetic head slider includes a write head having a single magnetic pole, the single magnetic pole having a main magnetic pole piece that extends to a medium opposing surface facing a magnetic disk. The main magnetic pole piece generates a recording magnetic field from a medium opposing surface side end face thereof being divided into an injection region and a non-injection region. Impurities which deteriorate magnetic properties are present in a higher concentration in the injection region relative to a concentration of the impurities in the non-injection region due to injection of the impurities in the injection region. The non-injection region has a narrower width at a leading end of the medium opposing surface side end face than at a trailing end of the medium opposing surface side end face.
