  • Patent number: 8319188
    Abstract: A portable gamma-ray detector for indicating the intensity of a source of gamma-rays, the nature of the source, and the direction to the source relative to an axis of the detector. The detector comprises a plurality of scintillation bodies arranged around the pointing axis, for example four scintillation bodies in a two-by-two array and separated from each other by aluminum foil. Thus gamma-rays from different directions are shielded from different ones of the scintillation bodies by the other scintillation bodies. The scintillation bodies are coupled to respective photo-detectors and a processing circuit is configured to receive output signals from the photo-detectors and to provide an indication of the direction to a source relative to the pointing axis of the detector based on the relative output signals from the different photo-detectors.

  • Patent number: 8313520
    Abstract: Methods for treating a migraine by cooling a patient's nasopharyngeal cavity are described. In one method, a cooling assembly is inserted into a nasal cavity through a patient's nostril. The cooling assembly includes a flexible balloon defining a chamber and a first elongate tubular member having a lumen in fluid communication with the chamber. A liquid having a temperature between about ?20° C. and about 37° C. is infused through the lumen of the first elongate tubular member into the chamber, wherein the flexible balloon expands to place it in contact with the nasal cavity. In another method, an elongate member having a plurality of ports is inserted into the nasal cavity. A perfluorocarbon spray and a gas are then delivered onto a surface of the nasal cavity through the plurality of ports.

  • Patent number: 8308786
    Abstract: A method for cerebral and systemic cooling by circulating a cold liquid through a nasal catheter looped through the patient's nasal cavities and around the nasal septum. The nasal catheter is inserted into the patient's first nostril, advanced through the nasal cavity, around the nasal septum and out of the patient's second nostril. A cold fluid having a temperature between about ?20° C. and about 37° C. is flowed though a lumen in the nasal catheter to cool the nasal cavity. The nasal catheter may have one or more flexible balloons mounted on the catheter such that when the catheter is looped around the nasal septum, the balloon(s) are positioned in a portion of the patient's first and second nasal cavities. When a cold liquid is circulated through the catheter lumen, the flexible balloons expand to a contact the inner walls of the nasal cavities and provide direct cooling of the nasal cavities.

  • Patent number: 8270397
    Abstract: The Fibre Channel standard was created by the American National Standard for Information Systems (ANSI) X3T11 task group to define a serial I/O channel for interconnecting a number of heterogeneous peripheral devices to computer systems as well as interconnecting the computer systems themselves through optical fiber and copper media at gigabit speeds (i.e., one billion bits per second). Multiple protocols such as SCSI (Small Computer Serial Interface), IP (Internet Protocol), HIPPI, ATM (Asynchronous Transfer Mode) among others can concurrently utilize the same media when mapped over Fibre Channel. A Fibre Channel Fabric is an entity which transmits Fibre Channel frames between connected Node Ports. The Fibre Channel fabric routes the frames based on the destination address as well as other information embedded in the Fibre Channel frame header. Node Ports are attached to the Fibre Channel Fabric through links.

  • Patent number: 8217577
    Abstract: An apparatus and method of modulating an electron beam to induce a high degree of spatial bunching uses multiple control grids located in close proximity to an electron-emitting cathode. An RF field couples to the electron beam in the cathode-grid gap to induce velocity modulation. The electron beam then propagates through a first control grid, allowing the velocity modulation to induce spatial bunching. The electron beam then traverses a gap between the first grid and a second control grid and interacts with the RF field to induce further bunching of the beam. Simulations show that bunching factors of 50:1 may be achieved.

  • Patent number: 8179705
    Abstract: A power subsystem is actively optimized to improve total subsystem efficiency in a way that is responsive to changes in load requirements, power supply variations, and subsystem temperature variations. Detailed, multidimensional power loss models are developed for constituent devices which are then combined into a power subsystem containing a controller and circuity for measuring device operating parameters such as input and output voltage, output current, and temperature. Operating parameters are continually monitored, and set points are correspondingly changed based on the detailed power loss models to achieve maximum overall efficiency for the instantaneous operating state of the system.

  • Patent number: 8165797
    Abstract: In a vehicular control object determination system, locus correlation degree calculator calculates a degree of correlation between a future travel locus of a vehicle estimated by first travel locus estimator based on a vehicle speed and a yaw rate and a future travel locus of the vehicle estimated by second travel locus estimator based on a past travel locus of the vehicle calculated by travel locus calculator. When control object determiner determines a control object based on the travel locus estimated by the first travel locus estimator and predetermined control object determination conditions, the control object determination conditions are modified according to the degree of correlation, that is, the degree of reliability of the travel locus estimated by the first travel locus estimator, thereby achieving both accuracy with which the control object is determined and determination of the control object at a distance.

  • Patent number: 8157767
    Abstract: A cerebral cooling device that uses a pressurized source to deliver a fluid that evaporates in the nasal cavity to provide cooling and has a balloon on the distal end that inflates from some of the pressure from the pressurized source. The device includes a nasal catheter having delivery ports located in the distal region and a balloon on the distal end. The proximal end of the catheter is in fluid communication with a pressurized source of a low boiling point fluid. A manifold located between the pressurized source and the catheter distributes the fluid and pressure from the pressurized source to a first lumen of the catheter to inflate the balloon and to a second lumen of the catheter through the delivery ports to cool the nasal cavity. A check valve in the manifold ensures that the fluid and pressure are first delivered to the balloon.
