  • Patent number: 7113623
    Abstract: Methods and systems for reconstruction of a three-dimensional representation of a moving arterial tree structure from a pair of sequences of time varying two-dimensional images thereof and for analysis of the reconstructed representation. In one aspect of the invention, a pair of time varying arteriographic image sequences are used to reconstruct a three-dimensional representation of the vascular tree structure as it moves through a cardiac cycle. The arteriographic image sequences maybe obtained from a biplane imaging system or from two sequences of images using a single plane imaging system. Another aspect of the invention then applies analysis methods and systems utilizing the three-dimensional representation to analyze various kinematic and deformation measures of the moving vascular structure. Analysis results may be presented to the user using color coded indicia to identify various kinematic and deformation measures of the vascular tree.

  • Publication number: 20060169644
    Abstract: A mechanical flotation system having only one cell may be nearly as efficient as one having two or more cells, yet provide an apparatus with a considerably smaller footprint, significantly reduced capital and operating costs, as well as be resistant to floating oil recovery platform wave effects. The single-cell mechanical flotation system may have one skim collection channel that at least partially surrounds a single gas ingestion and mixing mechanism. At least one baffle may direct suspended matter or floc toward the skim collection which may be circular. The gas layer over the liquid is not vented for the purpose of gasification. The vessel may be a cylindrical pressure vessel oriented vertically, and optionally the inlet may be tangential to the periphery of the vessel to impart liquid rotation inside the vessel when liquid is introduced.

  • Publication number: 20060161923
    Abstract: A method of task management in a data processing system having a first hardware entity and a second hardware entity, the first and second hardware entities having dissimilar functional capabilities. The method includes providing a task for processing, queuing the task in a priority task queue associated with both the first hardware entity and the second hardware entity, and associating a context designation with the task. In addition, the method includes specifying the minimum hardware entity functional capability necessary to process the task, selecting which one of the hardware entities shall process the task, and submitting the task to the selected hardware entity for processing.

  • Publication number: 20060155844
    Abstract: A log-in resource release system includes a set of lists for managing log-in requests to a processing cluster input/output port from host server input/output ports. Host servers that have been granted memory structures within a memory storage device (“configured hosts”) are granted priority access to a storage processing device's input/output port (“cluster port”). If the cluster port has exhausted its log-in resources, log-on requests from non-configured hosts will be not be accepted. New log-in requests from configured hosts will cause a host connected at a link or transport layer but not an upper layer to be logged off. If no hosts are connected only at the link or transport layer, a non-configured host connected at an upper layer will be logged off. If only configured hosts are connected and only at the upper layer, the log-on request by the configured host will be denied.

  • Publication number: 20060107002
    Abstract: Provided are a method, system, and program for an adaptor to read and write to system memory. A plurality of blocks of data to write to storage are received at an adaptor. The blocks of data are added to a buffer in the adaptor. A determination is made of pages in a memory device and I/O requests are generated to write the blocks in the buffer to the determined pages, wherein two I/O requests are generated to write to one block split between two pages in the memory device. The adaptor executes the generated I/O requests to write the blocks in the buffer to the determined pages in the memory device.

  • Publication number: 20060088530
    Abstract: This invention discloses methods, kits, and instructions to treat neovasculature diseases of the eye through the administration of a targeted photosensitizing agent and subsequent exposure to light of specific wavelength sufficient to photoactivate photosensitizing agent. The photosensitizing agent is bound to a composition that mediates site specific delivery to a neovasculature target tissue of a therapeutically effective amount of a photosensitizing agent that is activated by a relatively low fluence rate of light over a prolonged period of time. Diseases treatable under this invention, include: diabetic retinopathy; macular degeneration; and malignant uveal melanomas.

  • Publication number: 20060067889
    Abstract: Provided herein are conjugates, kits, articles of manufacture and methods for detection, diagnosis and treatment by photodynamic therapy of certain undesired biological substrate targets, including, but not limited to bacteria, viruses, and other pathogenic microorganisms, tumors and hyperproliferative tissue. In particular, the conjugates provided include a fluorophore or photosensitizer linked to a targeting moiety and a quenching agent in such a way that activation of the fluorophore or the photosensitizer is quenched unless the targeting moiety is bound to a target, whereupon the quenching agent dissociates or moves away from the photosensitizer, enabling activation of the photosensitizer upon irradiation with light of a suitable wavelength.

  • Patent number: 7018395
    Abstract: The present invention is drawn to methods for photodynamic therapy (PDT) of a target cell, target tissue or target composition in a mammalian subject, using a therapeutically effective amount of a targeted substance, which is either a targeted photosensitizing agent, or a photosensitizing agent delivery system, or a targeted prodrug. This targeted substance preferably selectively binds to the target cell, target tissue or target composition. Light at a wavelength or waveband corresponding to that which is absorbed by the targeted substance is then administered. The light intensity is relatively low, but a high total fluence is employed to ensure the activation of the targeted photosensitizing agent or targeted prodrug product.

  • Publication number: 20060059208
    Abstract: A system and method is described for resolving a conflict detected while synchronizing a first data object in a first store associated with a mobile device and a second data object in a second store associated with a server. Once the conflict is detected, properties of the first data object are compared with corresponding properties of the second data object. If the properties and the corresponding properties that differ are designated as mergeable properties, the properties and the corresponding properties are merged. Merging the properties involves sending a preferred state associated with each of the properties and the corresponding properties to the mobile device and the server for updating the first data object and second data object, respectively, when an initial state for the properties and the corresponding properties is different than the preferred state.

  • Publication number: 20060041664
    Abstract: Computer networks are provided with a resource efficient ability to generate link performance statistics. To calculate the average link utilization per I/O operation, a first counter accumulates the number of I/O operations processed by a link and a second counter accumulates the time required by the link to complete each I/O operation. The second value is then divided by the first value. The number of operations per second for a link may be computed by dividing the first number by a predetermined period of time and the average number of operations using the link may be computed by dividing the second number by the predetermined period of time. A third counter may be employed to accumulate the number of bytes transferred by a link during each I/O operation. Then, average size of an I/O operation may be computed by dividing the third number by the first number and the average bandwidth per link operation may be computed by dividing the third number by the predetermined period of time.

  • Publication number: 20060017771
    Abstract: A method for variable velocity printing includes printing a first swath at a first velocity, and printing a second swath at a second velocity. Thus, different swaths of a single print job can be printed at different swath velocities. By varying the swath velocity between swaths, mechanical vibrations that can degrade or negatively impact the quality of the resulting printed product can be ameliorated.
