Publication number: 20240153037Abstract: A method and system for correcting a difference in contrast agent density in a sequence of contrast-enhanced image frames. A reference image frame is defined in the sequence of contrast-enhanced image frames, and segmentation is performed on the reference image frame to determine a location of a region of interest within the reference image frame. The region of interest is a region of the reference image frame that contains contrast agent. Other image frames in the sequence of contrast-enhanced images are corrected based on a difference in contrast agent density/image intensity in the region of interest relative to the region of interest in the reference image frame.Type: ApplicationFiled: March 3, 2022Publication date: May 9, 2024Inventors: Sebastian Wild, Frank Michael Weber, Irina Waechter-Stehle, Jochen Peters, Arne Ewald, André Gooßen, Matthias Lenga, Tobias Wissel, David Prater

Publication number: 20240068135Abstract: Interlacing equipment may be used to form fabric and to create a gap in the fabric. The fabric may include one or more conductive strands. An insertion tool may be used to align an electrical component with the conductive strands during interlacing operations. A soldering tool may be used to remove insulation from the conductive strands to expose conductive segments on the conductive strands. The soldering tool may be used to solder the conductive segments to the electrical component. The solder connections may be located in grooves in the electrical component. An encapsulation tool may dispense encapsulation material in the grooves to encapsulate the solder connections. After the electrical component is electrically connected to the conductive strands, the insertion tool may position and release the electrical component in the gap. A component retention tool may temporarily be used to retain the electrical component in the gap as interlacing operations continue.Type: ApplicationFiled: November 8, 2023Publication date: February 29, 2024Inventors: Kyle L. Chatham, Kathryn P. Crews, Didio V. Gomes, Benjamin J. Grena, Storrs T. Hoen, Steven J. Keating, David M. Kindlon, Daniel A. Podhajny, Andrew L. Rosenberg, Daniel D. Sunshine, Lia M.

Patent number: 6172369Abstract: A flat panel detector for radiation imaging includes an array of transistor switches each of which is associated with a pixel electrode. A radiation transducer including a top electrode and a radiation conversion layer is disposed over the array. Inhibiting mechanisms are positioned over dead zones between adjacent pixel electrodes to inhibit the accumulation of charge in the radiation conversion layer at the dead zones when the top electrode is biased and the flat panel detector is exposed to radiation. In one embodiment, the inhibiting mechanism is constituted by islands formed of semiconductor material between the array and the radiation transducer. Each island is positioned over a dead zone between adjacent pixel electrodes and contacts a pixel electrode to allow charges accumulated on the islands to drift to the pixel electrodes.Type: GrantFiled: July 21, 1998Date of Patent: January 9, 2001Assignee: IFire Technology, Inc.Inventors: David Waechter, Wei Zhou, John Rowlands, Zhong Shou Huang

Patent number: 5780858Abstract: An electromagnetic radiation imaging device comprising an energy absorbing layer overlying an array of thin film transistors (TFTs). each of the thin film transistors incorporates a dual gate. The lower gate provides row selection, while the upper gate of the same device modulates current conducted by the transistor. By utilizing dual gates, a reduction in the number of transistors is achieved over prior art imaging devices, thereby increasing production yield. Furthermore, the use of dual gate transistors provides increased versatility in choosing the bias point of the transistors.Type: GrantFiled: October 4, 1996Date of Patent: July 14, 1998Assignee: Litton Systems Canada LimitedInventors: David Waechter, Surendra Singh

Patent number: 4678330Abstract: An apparatus and method for measuring solar radiation received in a vegetative canopy. A multiplicity of sensors selectively generates electrical signals in response to impinging photosynthetically active radiation in sunlight. Each sensor is attached to a plant within the canopy and is electrically connected to a separate port in a junction box having a multiplicity of ports. Each port is connected to an operational amplifier. Each amplifier amplifies the signals generated by the sensors. Each amplifier is connected to an analog-to-digital convertor which digitizes each signal. A computer is connected to the convertors and accumulates and stores solar radiation data. A data output device such as a printer is connected to the computer and displays the data.Type: GrantFiled: April 30, 1985Date of Patent: July 7, 1987Assignee: The United States of America as represented by the United States Department of EnergyInventors: Vincent P.
