Patent number: 12039958Abstract: Devices and methods that use a perceptual-driven approach to foveated displays with the goal of offering elegant degradation of image resolution with the increase of eccentricity and eye movements. As a result, the implementation leads to minimally perceivable image artifacts and image resolution discontinuity, and may further eliminate or limit the need for an eyetracker or scanning mechanism. Hereby we refer this approach as perceptual-driven continuous foveated display in contrast to the multi-level discrete foveation approach used previously.Type: GrantFiled: August 2, 2021Date of Patent: July 16, 2024Assignee: ARIZONA BOARD OF REGENTS ON BEHALF OF THE UNIVERSITY OF ARIZONAInventors: Hong Hua, Pengyinjie Lyu

Patent number: 12036595Abstract: A method and system are provided for using induction heating to shape a work piece panel into a preselected shape. The method includes positioning a work piece panel near or in abutment with at least a first induction coil. Alternating current (AC) having a preselected amplitude and frequency can be passed through at least the first induction coil while the work piece panel is subjected to at least one preselected shaping condition. An alternating electromagnetic field produced by the AC current, can cause eddy current in the work piece panel that can heat it to a preselected temperature for a preselected period of time while subjected to the preselected shaping condition, thereby causing the work piece panel to attain the preselected shape. The alternating electromagnetic field can also create a repelling electromagnetic force between the coil and the work piece panel, which could be a shaping condition.Type: GrantFiled: October 18, 2019Date of Patent: July 16, 2024Assignee: ARIZONA BOARD OF REGENTS ON BEHALF OF THE UNIVERSITY OF ARIZONAInventors: Christian Davila-Peralta, Justin Hyatt

Patent number: 12032108Abstract: The present invention provides a method of calibrating gamma-ray and photon counting detectors, including, but not limited to, monolithic crystal detectors. The method of the present invention is based on the observation that measurement of fan beam datasets allows the synthesis of collimated beam data to derive MDRFs by use of an algorithm that finds the common or intersecting data subsets of two or more orthogonal calibration datasets. This makes the calibration process very efficient while still allowing the full benefits of maximum-likelihood event-parameter estimation that incorporates the statistical nature of the light sensor measurements.Type: GrantFiled: December 20, 2022Date of Patent: July 9, 2024Assignee: Arizona Board of Regents on Behalf of the University of ArizonaInventors: Xin Li, Lars Furenlid

Patent number: 12029636Abstract: Systems featuring two or more encapsulation devices stacked together. The encapsulation devices house cells, such as but not limited to islet cells or stem cell derived beta cells or the like. e.g., for regulating blood glucose, or other cells or spheroids that can produce and release a therapeutic agent that is useful in the body, etc. The system may feature oxygen delivery, or in some cases no exogenous oxygen is delivered and vascularization of the device can help provide oxygen and other needed nutrient to the cells. The system of the present invention may be used in conjunction with other therapies such as an artificial pancreas. Stacking the devices with blood vessel formation around and in between them may allow for a decrease in the footprint that would be needed for implantation.Type: GrantFiled: September 2, 2022Date of Patent: July 9, 2024Assignee: ARIZONA BOARD OF REGENTS ON BEHALF OF THE UNIVERSITY OF ARIZONAInventor: Klearchos K.

Patent number: 12023479Abstract: A tubular pulsatile ventricular assist device (PVAD) system for providing forward flow of blood in a pulsatile, peristaltic, and non-hemolytic manner to help reduce the amount of blood clotting associated with current ventricular devices on the market. The system can encircle a portion of a blood vessel, and the system can sequentially apply a pressure through each port in a particular pre-determined patter so as to selectively occlude the lumen, thereby creating a pulsatile, peristaltic movement along a length of system. Said movement causes blood to flow through the portion of the blood vessel.Type: GrantFiled: June 12, 2019Date of Patent: July 2, 2024Assignee: ARIZONA BOARD OF REGENTS ON BEHALF OF THE UNIVERSITY OF ARIZONAInventors: Zain I.

Patent number: 12016973Abstract: Methods, systems, and devices for enhancing cancer immunotherapy featuring co-transplantation of encapsulated xenogeneic cells with separately encapsulated autologous or allogeneic cells, e.g., autologous or allogeneic tumor cells. For example, both a first cellular transplantation device housing a patient's own tumor cells and a second cellular transplantation device housing xenogeneic cells may be implanted into a patient. The presence of the xenogeneic cells elicits an enhanced immune response, e.g., the xenogeneic cells will draw in a large number of immune cells. Shed tumor antigens from the first cellular transplantation may then be taken up by the immune cells that were drawn to the xenogeneic cells. This will generate an anti-tumor immune response that is amplified relative to a response elicited by the encapsulated tumor cells alone.Type: GrantFiled: October 5, 2017Date of Patent: June 25, 2024Assignee: ARIZONA BOARD OF REGENTS ON BEHALF OF THE UNIVERSITY OF ARIZONAInventor: Klearchos K.

Patent number: 12020453Abstract: A microscopic technique for generating high-clarity, large volume 3D images of fluorescent tissue structure at subcellular resolution and capture transient activities. The technique includes capturing two orthogonal 2D projection of the sample volume by performing a projection scan with an excitation laser sweeping through the volume at up to 100 vps, tracking the scan depth using an electrically tuned lens to keep the emission image in focus and generate an xy plane volume projection image at the camera; and placing a PMT behind the excitation lens to collect emission passed through the excitation lens, wherein signals from the PMT form a focus scan projection at the yz plane; and then merging the xy and yz projections.Type: GrantFiled: January 29, 2020Date of Patent: June 25, 2024Assignee: Arizona Board of Regents on Behalf of the University of ArizonaInventors: Leilei Peng, Jun Ding, Dongli Xu

Patent number: 12019981Abstract: A machine reading system is described herein that includes a framework in which grammar rules can be developed using a concise language that combines syntax and semantics. The resulting technology thus reduces the development time for new grammars in a new domain. An enormous amount of information appears in the form of natural language across millions of academic papers and other literature sources. For example, in the biological domain, there is a tremendous ongoing effort to extract individual chemical interactions from these texts, but these interactions are only isolated fragments of larger causal mechanisms such as protein signaling pathways. The proposed rule-based event extraction framework can model underlying syntactic representations of events in order to extract signaling pathway fragments. Though application to the biomedical domain is herein described, the framework is domain-independent and is expressive enough to capture most complex events annotated by domain experts.Type: GrantFiled: June 10, 2021Date of Patent: June 25, 2024Assignee: ARIZONA BOARD OF REGENTS ON BEHALF OF THE UNIVERSITY OF ARIZONAInventors: Mihai Surdeanu, Marco A.
