  • Patent number: 6591127
    Abstract: An integrated, multi-modality imaging technique is disclosed. The embodiment described combines a split-magnet MRI system with a digital x-ray system. The two systems are employed together to generate images of a subject in accordance with their individual physics and imaging characteristics. The images may be displaced in real time, such as during a surgical intervention. The images may be registered with one another and combined to form a composite image in which tissues or objects difficult to image in one modality are visible. By appropriately selecting the position of an x-ray source and detector, and by programming a desired corresponding slice for MRI imaging, useful combined images may be obtained and displayed.

  • Patent number: 6586935
    Abstract: A technique is provided for characterizing and correcting for instabilities or variations in a magnet system of an MRI scanner. The technique makes use of a navigator pulse to read out navigator echo data in the absence of phase encode, or with phase encode effects rewound. The navigator data is used to characterize several potential effects of magnet system instabilities or variations, such as zeroth order phase shifts, first order (linear) phase shifts, bulk position shifts, and amplitude effects. The effects of the instabilities can be used, then, to correct image data acquired during an examination.

  • Patent number: 6587379
    Abstract: A technique is provided for reducing changes in the amount of a bias voltage that is applied to a device in an integrated circuit due to local changes on a bus providing the reference for the bias voltage signal. Local transients on the reference bus may occur due to the inductance of the integrated circuit packaging. To prevent the local transients from affecting the amount of bias applied to a device, the local bias signal is allowed to move common mode with the local reference signal by isolating the local bias signal from the bias source. The technique also provides for disabling the isolation of the local bias signal from the bias source in response to a control signal.

  • Patent number: 6583457
    Abstract: A container capacitor having a recessed conductive layer. The recessed conductive layer is typically made of polysilicon. The recessed structure reduces the chances of polysilicon “floaters,” which are traces of polysilicon that remain on the surface of the substrate, coupling adjacent capacitors together to create short circuits. The disclosed method of creating such a recessed structure uses successive etches. One of these etches selectively isolates a rim of the polysilicon within the container to recess the rim, while the remainder of the polysilicon in the container is protected by photoresist.

  • Patent number: 6583985
    Abstract: A portable computer docking station housing is provided on its bottom side with a support foot structure which is pivotable relative to the housing to prop it up on a horizontal work station surface in a selectively variable one of a series of different front-to-rear tilt angles thereon. This permits the opened display screen of a docked portable computer disposed on the top side of the docking station housing to be selectively adjusted upwardly and downwardly in a vertical plane to accommodate the height and viewing preferences of a user of the docked computer. A specially designed spring-loaded, manually operable clutch mechanism is useable to releasably lock the support foot in its selected pivotal orientation relative to the housing. Various peripheral device connection ports are conveniently incorporated in the support foot.

  • Patent number: 6582145
    Abstract: A connector system for protecting the transmission of signals from and/or to a tool in a high pressure environment. The system includes a connector through which a signal transmission line, such as an electrical cable or optical fiber extends. The connector is coupled to a protective tube, and includes an internal chamber in communication with the interior of the tube. A fluid, such as a liquid, is disposed within the connector and the tubing at a pressure higher than the environmental pressure. In the event of a leak at, for instance, the connector, the high pressure fluid flows outwardly rather than allowing the inflow of deleterious fluid from the environment.

  • Patent number: 6581130
    Abstract: Address translation between various peripheral bus interfaces is provided through a bus interface device. Specifically, the bus interface device translates incoming transactions from a source bus interface to a different address or location within a destination bus interface. Flexibility for communications between multiple bus interfaces having different, possibly conflicting, address spaces is ensured by allowing the internal translation registers to be dynamically reprogrammed. Reprogramming of the translation registers may occur during runtime bus operations. These registers define translation windows within which a transaction will be claimed and translated to the destination bus interface. Translation is accomplished using the translation registers to identify portions of the incoming received address which should not be translated because those portions contain the information to be communicated.
