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
