  • Publication number: 20090036341
    Abstract: The present disclosure is directed to methods and compositions for clearing and cleaning enteral feeding tubes. More particularly, the composition is an ingestible gel composition that comprises enzymes for degrading buildup in enteral feeding tubes, carrageenan, and divalent metal ions or a source thereof. The carrageenan present in the composition stabilizes the enzymes at room temperatures, allowing for long-term storage of the composition. Upon injecting the gelled composition into the feeding tube, body heat from the patient melts the gel, and the enzymes are released to act on debris present in the feeding tube.

  • Publication number: 20090027099
    Abstract: An output driver circuit 18 is provided having an operating mode in which the output signal has a variable level dependent upon an input signal and a clamping mode in which the output signal is clamped to a fixed level. The output driver circuit includes a control circuit 20 and an output buffer 22. The output buffer is formed of high strength, high current transistors 24, 26 which also tend to suffer high leakage. In the clamping mode, the power supply to the output buffer 22 is isolated, but the control circuit 20 serves to supply a control signal on line 36 to at least one transistor 26 within the output buffer 22 which is controlled to remain conductive and accordingly serve as a clamping transistor which clamps the output from the output buffer 22 to a fixed level.

  • Patent number: 7482908
    Abstract: Radio-frequency devices that have internal radio-frequency chips are personalized. A radio-frequency device is inserted into a package. An identifier is read electromagnetically from the radio-frequency chip with a radio-frequency transceiver while the radio-frequency device is within the package. Personalization information is written electromagnetically onto the radio-frequency chip while the radio-frequency device is within the package. An association between the personalization information and the identifier is recorded on a storage device.

  • Publication number: 20090021639
    Abstract: In order to correct the skew experienced by the end user, a ‘reverse skew’ is applied by a video IVR, resulting in synchronized data at the edge. This is achieved by ‘sliding’ the time-bases of audio relative to video prior to delivery. Therefore, the data as received by the end user is synchronized. Media interfaces towards the video IVR are full duplex; the server corrects the skew in the respective halves of the duplex, particularly dependent on the type of service being deployed on the video IVR. For messaging applications, correcting the skew of the received data is important prior to the actual storage of the data. By applying the same technique as used for play-out, the skew can be corrected. The video IVR slides the time-base of audio relative to video before saving the multimedia data to the storage device. As a result, data saved is synchronized.

  • Publication number: 20090022224
    Abstract: A method and apparatus for performing motion estimation in a digital video system is disclosed. Specifically, the present invention discloses a system that quickly calculates estimated motion vectors in a very efficient manner. In one embodiment, a first multiplicand is determined by multiplying a first display time difference between a first video picture and a second video picture by a power of two scale value. This step scales up a numerator for a ratio. Next, the system determines a scaled ratio by dividing that scaled numerator by a second first display time difference between said second video picture and a third video picture. The scaled ratio is then stored calculating motion vector estimations. By storing the scaled ratio, all the estimated motion vectors can be calculated quickly with good precision since the scaled ratio saves significant bits and reducing the scale is preformed by simple shifts.

  • Publication number: 20090022259
    Abstract: A fuel rod includes a cladding tube with a wear-inhibiting coating. In one embodiment, the coating is made of a metallic powder material that is applied to the exterior surface of the cladding tube using a thermal spray process. In an alternative embodiment, the coating is a composite made of a metallic powder material, and a ceramic powder material or a metal oxide hard phase powder material that is simultaneously applied with the metallic powder material to coat the cladding tube. The coating can be applied to selected areas of the fuel rods where debris tends to fret the fuel rod.

  • Patent number: 7479503
    Abstract: Multiple sclerosis and rheumatoid arthritis can be treated effectively using photodynamic therapy. In this protocol, a photoactive compound is administered, allowed to distribute in the effected subject, and the subject is then irradiated to activate the photoactive compound. Alternatively, the blood of a subject to be treated can be subjected to PDT extracorporeally. In the case of rheumatoid arthritis, localized treatment at the joints may also be employed.
