  • Patent number: 8090394
    Abstract: This disclosure describes a dynamic pattern elimination compression method to eliminate redundant patterns, the content of which is not known a priori, by identifying the candidate dynamic patterns and marking them, then checking to see if there are any duplicate occurrences within the entire message by searching for markers, if a marker is found, checking to see if the pattern occurred before, if not, assigning a unique variable to the pattern, if so replacing the pattern with the variable that was assigned for this pattern, and if a pattern is found only once, removing the variable assigned to it.

  • Patent number: 8059623
    Abstract: This disclosure describes a new interference avoidance Medium Access Control (MAC) protocol that combines contention-free and contention-based MAC protocols into a heterogeneous MAC protocol used for forwarding VoIP traffic in VoIP systems on wireless networks using multiple base stations which addresses additional interference elimination and the need to transport high bit-rate data to multiple users over wired and wireless means.

  • Patent number: 8005279
    Abstract: The present invention discloses a capsule endoscope image display controller (26) including: an image-to-image similarity calculating unit (36) that calculates, for each image included in an image sequence captured by a capsule endoscope which moves within the digestive organs, a similarity between the image and its temporally consecutive image; an amount-of-movement calculating unit (47) that calculates, for each image included in the image sequence, an amount of movement of a feature area included in the image; a video state classifying unit (41) that classifies, for each image included in the image sequence, a video state of the image into one of the following states, based on the video state, the similarity, and the amount of movement of the image: (a) “stationary state” indicating that the capsule endoscope is stationary, (b) “digestive organs deformation state” indicating that the digestive organs are deformed, and (c) “capsule moving state” indicating that the capsule endoscope is moving, based on the

  • Patent number: 7937479
    Abstract: A system and method of associating at least two communication devices is provided. First information identifying a first communication device and second information identifying a second communication device is received via a link layer protocol over a data network. It is determined if the first communication device and the second communication device are co-located based on first link layer data associated with the first communication device and second link layer data associated with the second communication device. An association is triggered between the first information and the second information if the first communication device and the second communication device are determined to be co-located.

  • Publication number: 20050178075
    Abstract: An exquisite marble fireplace mantle has a left marble pillar (1) and a right marble pillar (2) positioned vertically on a marble slab base (3) at a predetermined distance from oppositely disposed marble front walls (4, 5) of the fireplace mantle and extended to positions of support of marble display shelving (6, 12, 22) proximate a top of the marble fireplace mantle. Vertical and horizontal components are made of marble slabs that are cut to shape and grooved for tongue-and-groove fitting of adjoining joints of all-marble components that can have ground and polished visible surfaces. Selected vertical components that rest on horizontal surfaces are location-pinned in place.
