A method and associated system of implanting a vertebral anchor such as a pedicle screw assembly includes the steps of implanting a number of pedicle screws into a series of vertebrae; attaching a number of provisional posts to respective pedicle screws, each provisional post including a provisional saddle; bending a rod to conform to a desired alignment of the provisional saddles; removing the provisional posts from the pedicle screw heads; and connecting the bent rod to the pedicle screw heads. Advantageously, the method allows external fitting and sizing of a fixation rod before it is implanted and secured to the vertebral anchors via a minimally invasive manner.

A method for treating tumors, such as uterine leiomyomata, includes inserting an ablation apparatus into a pelvic region and positioning the ablation apparatus into a pelvic tumor.

The method further includes delivering electromagnetic energy or other energy through the ablation apparatus to the pelvic tumor to directly ablate the tumor. A surgical system for ablating pelvic tumors is also provided.

A method for restoring a virtual path, provisioned between a source and a target node, in a mesh zoned optical network is described. The method, in one embodiment, broadcasts or floods restore path requests in the network to expedite the identification of an alternate route and minimize the service disruption for failed virtual path. The flooding of requests is controlled to ensure efficient performance of the network yet guaranteeing minimum restoration time to allow critical telecommunication related traffic to flow through the network with virtually no interruption. The constant update of nodal topology by each node allows a fast identification of alternate physical path for failed virtual path.

A user interface for a computer-implemented Multi-Planar Reformatting (MPR) system comprises three display areas in which are displayed three orthogonal MPR images of the volume data set; a curve drawing tool to allow a user to define a curve through the volume data set; six selectable icons each representing one of six possible combinations of a plane parallel to one of the orthogonal MPR images and a direction substantially normal to a plane parallel to one of the other two MPR images, using which the user selects an approximate direction for the curve; and a fourth display area displaying a curve-related MPR image related to one or more points along the curve. The icons may be individually selectable to allow user input of adequate orientational information for a curved MPR image, or selectable in pairs for input of directional information for a cross-curve MPR image. Alternatively, three icons may be provided for a cross-curve MPR system. A tool to allow rotation of a curved MPR image about the curve can be provided, as can visual indicators of the depth of the curve within the volume, and of the orientation of the cross-curve image.

An artificial spinal disk prosthesis comprised of an artificial disk (101), mounting bracket (105) assembly that secures the disk to at least one vertebrae and a sliding rod (104) that connects the two whereby the shape of the components determines the range of motion of the disk, thus allowing desirable motions of the disk consistent with normal body motions and preventing undesirable motions of the artificial disk. In the preferred embodiment, the angular motion of the disk is controlled by a hinge that is on the side of the artificial disk. In the preferred embodiment, the artificial disc is connected to the spine via one vertebra.

The tracking system is configured to determine a location of the marker relative to the bone and to match at least one anatomical feature of the bone of the patient to an image of the bone. The display is in communication with the tracking system and adapted to show an image of the location of the marker relative to the image of the bone while the marker imparts the pigment on the bone.

Single-walled carbon nanotubes (SWNTs) are decorated with metal nanoparticles to form high-performance flexible hydrogen sensors. The special process to form the high-performance flexible hydrogen sensors can combine a dry transfer printing technique and modification of SWNTs with palladium (Pd) nanoparticles to provide high-performance hydrogen sensors with excellent mechanical flexibility on plastic substrates. Two approaches can be used to decorate the SWNTs. One is physical deposition, such as electron beam evaporation (EBE) and the other is electrochemical deposition which can selectively grow palladium nanoparticles on the surface of the SWNTs, resulting in significantly decreasing the use of palladium. Preferably, the Pd nanoparticles are deposed on the SWNTs in a discontinuous arrangement so that the Pd nanoparticles are spaced away from each other to form individual discontinuous Pd nanoparticles rather a continuous Pd film. Advantageously, the SWNTs are arranged with substantial semiconducting pathways. Desirably, the high-performance flexible hydrogen sensors have an excellent response and recovery time, provide superior sensitivity for detecting hydrogen, and are bendable to conform to the contours of other structures.

A network for an industrial control system employs a ring topology that is normally opened by a ring supervisor at the ring supervisor. Upon failure of the network, the ring supervisor reconnects the ring to provide an alternative transmission path around the failure point. High speed operation is reconciled with the ability to use commercial switching integrated circuits through a dual communication channel of communicating a network state as either closed or open using both high-speed hardware handled beacon frames and low-speed software processed announce frames.

The nanofabrication of a hydrogen gas nanosensor device from single straight and branched, tripod shaped ZnO nanorods using in-situ lift-out technique, performed in the chamber of a focused ion beam (FIB) system is disclosed. Self-assembled ZnO branched nanorods have been grown by a cost-effective and fast synthesis route using an aqueous solution deposition method and rapid thermal processing.

High quality ZnO nanorods were obtained with a 90% success rate for building nanodevices. The fabricated nanosensor can gauge 150 ppm hydrogen gas in the air at room temperature. The nanosensor has selectivity for other gases such as oxygen, methane, carbon monoxide and liquid propane gas. The ZnO nanorod sensors of the present invention also operate at low power of less than 5 microwatts.

A method and a storage server for backing up data involves mass storage devices of users of the service that connect to the storage server of the service provider over a public data network. The customers store the data with their terminals. The data is stored to the file system of the mass storage device which encrypts the stored data and transfers the data in encrypted form over the public data network to the storage server. The storage server calculates error correction data from the encrypted data. The error correction data is stored in the mass memory of the storage server. When recovering the stored data of the users, the storage server requests the stored data of all the users whose data was used for the error correction data calculation over the public data network to be used for the recovery calculation.

The invention relates to a saturable absorber structure (10) with multiple-layer epitaxial heterostructure absorbers. Typically the structure comprises first absorber layers of a quantum well semiconductor QW-material, which has a nonlinearly on radiation intensity dependent optical absorption; first contacting layers of a first optically transparent semiconductor material against a surface or surfaces of said first absorber layers; and a first Bragg-reflector (23). The first contacting layers have lattice fit or pseudomorphism with said first absorber layers. The absorber layer (13, 13a, 13b) of the QW-material has a thickness (S) of at maximum 60 nm. Further, said first optically transparent semiconductor material of the contacting layer (14, 14a, 14b, 14c) is a reactive R-material, which semiconductor material contains two or more main components, at least one dopant (M2), and at least one metallic alloying element (M1) substituting one of said main components and enhancing the incorporation of said dopant(s). The metallic alloying element has a concentration of at least 50 atomic-% of that main component it substitutes. This way the charge carriers originating in said QW-material of the first absorber layer has a first recombination time at maximum 100 picoseconds determined by recombination of the charge carriers at sites of said dopant(s), thus forming a fast saturable absorber.
