  • Patent number: 7822766
    Abstract: A system and method for autonomically maintaining group referential integrity across a distributed directory. When a server receives an operation request from a client regarding an entry in the distributed directory, the server sends a request to the particular server containing the entry to be modified that instructs the server to modify the entry, but without performing a referential integrity check. The server then determines whether the request returned successfully. If so, the server sends a request to each server in the network to perform the requested operation on all group references for the entry, but without actually performing the requested operation on the entry itself. If all of these requests return successfully, the server notifies the requesting client that the requested operation has been performed.

  • Patent number: 7821462
    Abstract: A dual-polarized radiating element is formed from two orthogonally oriented monopole radiators disposed on a dielectric substrate. An RF image plane placed orthogonally to the two monopole radiators presents a balanced excitation for element impedance optimization that allows for operation over multiple octave bandwidths with a physically compact device. The dual-polarized radiating element provides a broad field-of-view (FOV) as a stand alone radiator and may be used in a phased array.

  • Patent number: 7819880
    Abstract: A surgical instrument has an elongate guide member and a reciprocable member. The elongate guide member provides a protected path of travel for an implant from outside the body to a position near a damaged tissue site. The reciprocable member is movable along the elongate guide member to push the implant along its path of travel. The reciprocable member can include an implant carrier. The implant can be an orthopaedic implant for repair or regeneration of soft tissue at a damaged joint site. The implant can be larger than the transverse dimension of the elongate guide member and folded or rolled to fit within the elongate guide member. Use of this instrument protects the implant from damage as it is delivered to the damaged joint site. The invention also includes a surgical method for delivering an implant to a damaged tissue site.

  • Patent number: 7820333
    Abstract: A fuel cell system wherein a plurality of fuel cells are arranged in a series of stages, the number of fuel cells decreasing in number in each stage from anode gas inlet to the anode gas outlet. The system allows for parallel flow to all of the cells in a given stage and series flow between the various stages. A similar configuration is present on a cathode side of the system. However, the direction of flow is reversed, providing a greater number of cells in the stage nearest the cathode outlet and a fewer number of cells in the stage near the cathode gas inlet. The invention further provides for the various stages to be configured such that the direction of flow of the anode gas of a given stage is generally opposite the direction of flow of the cathode gas of a given stage.

  • Patent number: 7819826
    Abstract: A long-term implantable ultrasound therapy system and method is provided that provides directional, focused ultrasound to localized regions of tissue within body joints, such as spinal joints. An ultrasound emitter or transducer is delivered to a location within the body associated with the joint and heats the target region of tissue associated with the joint from the location. Such locations for ultrasound transducer placement may include for example in or around the intervertebral discs, or the bony structures such as vertebral bodies or posterior vertebral elements such as facet joints. Various modes of operation provide for selective, controlled heating at different temperature ranges to provide different intended results in the target tissue, which ranges are significantly effected by pre-stressed tissues such as in-vivo intervertebral discs. In particular, treatments above 70 degrees C., and in particular 75 degrees C.

  • Patent number: 7822731
    Abstract: Described are techniques for managing a sequential stream in a data storage system. A front-end component receives a plurality of data operations for a plurality of data portions and determines that the plurality of data portions are associated with a sequential stream. Each of the plurality of data portions of the sequential stream is associated with a sequential stream identifier, and a position indicator uniquely identifying a position of said each data portion in said sequential stream. Each of the plurality of data portions that is prefetched is associated with a remaining prefetched identifier and included in a prefetched chunk of data portions. The front-end component uses information about said sequential stream in connection with managing said sequential stream. The information includes the sequential stream identifier, one or more position indicators, and one or more remaining prefetched identifiers.

  • Patent number: 7821084
    Abstract: Rather than increasing the mass of the structure, the structure in a sensor system suspends its substrate from some mechanical ground. Motion of the substrate relative to the mechanical ground thus provides the movement information. To those ends, the sensor system includes a base, a substrate, and a flexible member suspended from at least a portion of the substrate. At least a portion of the flexible member is capable of moving relative to at least a portion of the substrate. In addition, the flexible member is secured to the base, thus causing the substrate to be movable relative to the base. Moreover, the mass of the substrate is greater than the mass of the flexible member. The substrate and flexible member are configured to interact to produce a motion signal identifying movement of the base.

  • Patent number: 7821263
    Abstract: A method for frequency selective and slice selective magnetic resonance imaging (MRI) is provided. A B0 field is applied. A self-refocused spatial-spectral (SPSP) RF pulse is applied. A readout of a portion of k-space for the excited slice is performed. A second self-refocused SPSP excitation RF pulse is applied, wherein the second self-refocused SPSP excitation has an 180° echo phase difference from the self-refocused SPSP excitation. A second readout of a portion of k-space for the excited slice was performed. A difference between the readout and the second readout was found. The previous steps were repeated until k-space has been filled for the excited slice. The previous steps were repeated for a plurality of slices.
