  • Memory efficient representation of relational data with constant time random access to the data itself
    Patent number: 8819089
    Abstract: An efficient method for storing relational data in a memory space uses B tree and B+ tree structures to store data for a database where non-identical values are stored in a string buffer and pointers to the string buffer are stored in a table buffer, and where identical data is stored only once, and each instance of that value in the database is referenced by a pointer to such identical data corresponding to the locations in the database where that identical value exists, thereby preserving physical memory and increasing the storage capacity of a fixed memory space.
    Type: Grant

    Date of Patent: August 26, 2014
    Assignee: Antenna Vaultus Inc.
    Inventors: Arvind Goyal, Gennady Agranov
  • Method and apparatus for improving low-light performance for small pixel image sensors
    Patent number: 8462220
    Abstract: Method and apparatuses processing pixel values from a captured image include receiving an array of digital pixel values corresponding to a captured image, and computing a rolling sum of the array of pixel values. Computing a rolling sum includes selecting successive groupings of the pixel values, each grouping comprising N×M pixel values, summing pixel values in each of the successive groupings, and forming an output image using the summed pixel values.
