  • Patent number: 12045361
    Abstract: In some embodiments, an apparatus includes a memory and a processor. The processor is configured to receive an index file that associates a characteristic in a set of documents with a set of information associated with the characteristic in the set of documents. The processor is further configured to generate an index identifier associated with the index file and calculate a set of pseudorandom logical block identifiers associated with a set of storage locations of a database based on the index identifier. The processor is then configured to parse the index file into a set of index data portions and send a signal to the database to write each index data portion from the set of index data portions at a different storage location within the database as indicated by a different identifier from the set of pseudorandom logical block identifiers.

  • Publication number: 20190386364
    Abstract: Resonant frequency stability of passbands or stopbands is provided over varying incidence angles and polarizations in a dual band frequency selective surface (FSS) device. The FSS device comprises an array of fractal unit cells. The fractal elements may comprise single fractal, or double fractal, or convoluted, or split ring resonator slot elements printed on a thin dielectric substrate. Each cell includes a first fractal pattern and a second fractal pattern which interact to provide the improved performance. In one form, a two-screen fractal FSS is etched on both sides of a thin dielectric substrate. The top FSS screen's unit cell has one fractal loop patch element, while the bottom FSS screen's unit cell has a higher order iteration of the same fractal. In another form, two fractal screens are incorporated in one dielectric layer positioned between two substrate layers. In yet another form, two fractal loop slot element FSSs are provided.

  • Patent number: 10402109
    Abstract: In some embodiments, an apparatus includes a processor configured to receive an instruction to read a data file within a database and an identifier associated with the data file. The processor is also configured to identify, based on the identifier, a set of logical block identifiers associated with a set of storage locations of the database, and retrieve data stored at each storage location from the set of storage locations using the set of logical block identifiers. The processor is then configured to identify, based on the data stored at each storage location from the set of storage locations, a subset of storage locations from the set of storage locations. The data stored at each storage location from the subset of storage locations pertain to the data file. The processor is configured to compile the data file based on the data within the subset of storage locations.

  • Patent number: 10275611
    Abstract: In some embodiments, a method includes receiving, at an encrypted sharing server and from a source compute device, a share request to share first encrypted index data with a destination compute device. The method includes defining a data record including (1) information identifying the destination compute device and (2) a first set of logical block identifiers. The first set of logical block identifiers is generated based on unencrypted index data associated with the first encrypted index data and associated with a first set of storage locations. Each storage location from the first set of storage locations stores at least one index entry from a first set of index entries of the first encrypted index data. The method further includes receiving a search request associated with a search string and sending a signal to cause a subset of index entries to be sent to a destination compute device.
