Patent number: 9257257Abstract: Provided is a Schottky emitter having the conical end with a radius of curvature of 2.0 ?m on the emission side of an electron beam. Since a radius of curvature is 1 ?m or more, a focal length of an electron gun can be longer than in a conventional practice wherein a radius of curvature is in the range of from 0.5 ?m to not more than 0.6 ?m. The focal length was found to be roughly proportional to the radius of the curvature. Since the angular current intensity (the beam current per unit solid angle) is proportional to square of the electron gun focal length, the former can be improved by an order of magnitude within a practicable increase in the emitter radius. A higher angular current intensity means a larger beam current available from the electron gun and the invention enables the Schottky emitters to be used in applications which require relatively high beam current of microampere regime such as microfocus X-ray tube, electron probe micro-analyzer, and electron beam lithography system.Type: GrantFiled: June 30, 2006Date of Patent: February 9, 2016Assignees: SHIMADZU CORPORATION, UNIVERSITY OF YORK HESLINGTONInventors: Shin Fujita, Mohamed El-Gomati, Torquil Wells

Patent number: 8825132Abstract: An NMR experiment on hyperpolarizable magnetic nuclei of substrate molecules in a living human or animal body, involves polarizing the substrate molecules by non-hydrogenating para-hydrogen induced polarization (=NH-PHIP) into a singlet/pseudo singlet state in low magnetic field and injecting the substrate molecules into the living body, the body or a part thereof being previously located inside a magnet at low magnetic field. The magnet is switched on to high magnetic field, and in at least part of the substrate molecules, the singlet state/pseudo singlet state is converted into observable magnetization. An MRI or MRS measurement is carried out with the living body or the part thereof, collecting data from the substrate molecules. The NMR experiment is well applicable on hyperpolarized nuclei within a patient, with reduced losses of magnetization due to relaxation processes.Type: GrantFiled: July 4, 2012Date of Patent: September 2, 2014Assignees: Bruker BioSpin GmbH, The University of YorkInventors: Joost Lohman, Simon Benedict Duckett, Gary George Green, Antonio Giuseppe Gianotti

Publication number: 20140218691Abstract: In one example of the invention a patient display is provided on which a fixation graphic or video is shown in substantially the centre of the display, and then target graphics or video are shown at different positions on the display about the centre. A test subject is positioned in front of the patient display at a known distance, and a camera captures an image of the test subject's eyes, to allow gaze direction determination to be performed. The captured images are displayed to a clinician user by a controlling test application, the clinician making a determination based on the images as to whether the test subject saw a target graphic or video when it was displayed. The clinician user then makes an appropriate input into the controlling test application, which also logs the position at which the target image was displayed.Type: ApplicationFiled: April 3, 2014Publication date: August 7, 2014Applicants: University of York, Cambridge Enterprise LimitedInventors: Adar Pelah, Louise Elizabeth Allen, Michael Edward Slater, Andrew Robert Jackson
