Patent number: 7224365Abstract: System and method for transferring thematic information over the Internet in which graphical representations for different themes are created in a vector format, the vector graphics are imported into the frames of an animation movie, the frames of the movie are downloaded from the server to the client, and the frames are selectively overlaid to display different themes. The movie comprises a menu and a plurality of overlays that can be accessed by selecting topics on the menu. The menu file is downloaded first, and then data files for the overlays are downloaded in sequence. If the client selects a topic before the data file associated with it has been downloaded, the download is interrupted, and the data file for the selected topic is downloaded immediately. The amount of data that must be downloaded for thematic maps is minimized by downloading the outline of the region as a separate frame or overlay, and using that overlay with the overlays for a number of different themes.Type: GrantFiled: March 23, 2001Date of Patent: May 29, 2007Assignee: Totally Global, Inc.Inventors: Michael Howard Seideman, Geoffrey Thomas Gates, Jon Floyd Eberly, Thomas Philip Zito

Patent number: 6984201Abstract: A blood circulation assistance device (1), for location around a blood conduit (20). The device comprises: an inflatable bladder (10) moveable between a contracted form and an expanded form, for compressing the blood conduit (20) to provide counterpulsation. Pump means (30) in fluid communication with the bladder (10) move the bladder (10) from the contracted form to the expanded form. The pump means (30) comprises a centrifugal impeller (62) rotatable about an axis (61) to effect pumping. The impeller (62) is moveable axially between first and second positions to effect a reversal of the direction of pumping. Control means (50), in communication with the pump means, is capable of monitoring the cardiac cycle of an individual and triggering the pump means (30) to move the bladder (10) to the expanded form at diastole. An outer cuff, surrounds at least a portion of the bladder (10), providing an outer limiting extent to the movement of the bladder (10).Type: GrantFiled: March 24, 2003Date of Patent: January 10, 2006Assignee: Harefield Cardiac LimitedInventors: Asghar Khaghani, Geoffrey Thomas Andrews, Christopher Bowles, Nigel Gordon Smith

Publication number: 20040080756Abstract: A beamsplitter (16) splits a source beam (14) into a sample path (17) and a reference path (19). The reflected beams recombine to form an interference signal (100). Reference surface (20) is horizontaly suspended on a loudspeaker membrane (30), and moved via a voice coil attached to the membrane (30). this arrangement isolates the reference surface (20) from external vibrations. The surface profile of the sample (18a) is analysed via the interference fringes, which are determined by computing maxima or minima in the statistical variance of digital data representing the interference signal (100). The apparatus may be used for calibrating laser ablation procedures in eye surgery.Type: ApplicationFiled: December 22, 2003Publication date: April 29, 2004Inventors: Phillip George Reid, Hank Christian Sciberras, Zheng Lin Wang, Geoffrey Thomas Dair

Publication number: 20030167446Abstract: A method of recording changes to a markup language file which employs application-defined tags. The changes are recorded in a delta file which is also a markup language file providing validation of the recorded changes against substantially the same markup language structure as that of the markup language file being changed. Where the original markup language file is an XML file with a DTD, a DTD can be created for the delta file which substantially follows the DTD of the original markup language file. Strict compliance of the data recorded in the delta file with the delta DTD provides validation of the changes with respect to the original XML file.Type: ApplicationFiled: April 8, 2003Publication date: September 4, 2003Inventor: Semer Geoffrey Thomas

Publication number: 20030085666Abstract: In an electron beam tube arrangement, such as an IOT amplifier, an input cavity surrounds an electron gun. The cavity includes parts which are at high and low relative electrical potentials. These are separated by RF chokes to provide de isolation whilst acting as a short circuit to high frequency radiation coupled into the cavity. The arrangement also includes a bypass capacitor located behind the electron gun which short circuits stray or leakage radiation to prevent deterioration of the amplified signal. The bypass capacitor presents a distributed capacitance of low inductance. In one embodiment, the RF choke and bypass capacitor include insulating material defined by a common member on which metallisation layers are deposited.Type: ApplicationFiled: September 12, 2002Publication date: May 8, 2003Inventors: Steven Bardell, Geoffrey Thomas Clayworth
