Patent number: 10589124Abstract: Systems and methods for stimulating neural tissue are disclosed. An array of optically emissive pixels is configured to deliver light to the neural tissue of a subject. Individual pixels within the array can be addressed to selectively illuminate a portion of the neural tissue when a neurological event occurs. The system can also include an array of microelectrodes in electrical communication with the array of pixels and a power source. A biocompatible substrate can be used to support the microelectrodes pixels, and the power source. A microelectrode circuit and a pixel circuit can also be supported by the biocompatible substrate.Type: GrantFiled: January 13, 2015Date of Patent: March 17, 2020Assignee: Arizona Board of Regents on behalf of Arizona State UniversityInventors: Joseph Smith, Barry O'Brien, Yong-Kyun Lee, Edward Bawolek, Jennifer Blain Christen, Michael Goryll, Jitendran Muthuswamy, George R. Kunnen, David Allee

Patent number: 10180504Abstract: Some embodiments include a system having a detection sensor array, which includes multiple detection sensors with each detection sensor having an enabled state and a disabled state, and having a control module configured to operate the detection sensor array. Under the enabled state, each detection sensor is configured to detect and identify electromagnetic radiation, and under the disabled state, each detection sensor is configured not to detect and identify electromagnetic radiation. Further, the detection sensor array comprises a test state and an operational state. Other embodiments of related systems and methods are also disclosed.Type: GrantFiled: May 5, 2016Date of Patent: January 15, 2019Assignees: ARIZONA BOARD OF REGENTS ON BEHALF OF ARIZONA STATE UNIVERSITY, THE UNITED STATES OF AMERICA AS REPRESENTED BY THE SECRETARY OF THE ARMYInventors: Joseph Smith, Eric Forsythe, David Allee

Patent number: 10147360Abstract: Described herein are display devices having architectures with a reduced number of external connections from the display to the external electronics, which allows for an increase in the pitch of the external connections, thereby improving reliability and flexibility, and reducing costs. The architecture of these devices is based on using multiplexers to connect external source lines to the individual display column lines. Accordingly, data signals can come into the display on a reduced number of external source lines as compared to the number of display column lines. The architecture allows for high-reliability, rugged contacts to a small-sized display by avoiding the need for high resolution interconnects.Type: GrantFiled: March 31, 2015Date of Patent: December 4, 2018Assignee: Universal Display CorporationInventors: Michael Hack, David Allee

Patent number: 9910171Abstract: Some embodiments include a system. The system includes a sensor device having a sensor element having a sensor output and an amplification element having at least one amplification stage, an amplifier input, and an amplifier output. The sensor output can be coupled to the amplifier input. Further, each amplification stage of the amplification stage(s) can have at least four thin film transistors, an input node, and an output node. Meanwhile, the sensor element can detect a physical quantity and/or an event and can provide an electric signal to the amplification element in response to detecting the physical quantity and/or the event, and the amplification element can amplify the electric signal received from the sensor element. Other embodiments of related systems and methods are also disclosed.Type: GrantFiled: September 11, 2015Date of Patent: March 6, 2018Assignee: ARIZONA BOARD OF REGENTS ON BEHALF OF ARIZONA STATE UNIVERSITYInventors: George Kunnen, David Allee

Patent number: 9903959Abstract: Some embodiments include a method of operating a detection sensor array. The detection sensor array has multiple detection sensors. Each detection sensor of the multiple detection sensors has an enabled state and a disabled state, and each detection sensor of the multiple detection sensors is configured to detect and identify electromagnetic radiation when in the enabled state and not to detect and identify electromagnetic radiation when in the disabled state. The detection sensor array also has a test state in which all of the multiple detection sensors operate in the enabled state when the detection sensor array is in the test state. Other embodiments of related systems and methods are also disclosed.Type: GrantFiled: May 5, 2016Date of Patent: February 27, 2018Assignee: ARIZONA BOARD OF REGENTS ON BEHALF OF ARIZONA STATE UNIVERSITYInventors: Joseph Smith, Eric Forsythe, David Allee

Publication number: 20070285067Abstract: An electrical system according to various aspects of the present invention includes a supply configured to provide a signal at a desired level. The supply monitors the output signal and compares the output signal to multiple thresholds. If the signal crosses a coarse-adjustment threshold, the supply coarsely adjusts the output to the load to quickly drive the signal toward the target level. If the signal crosses a fine adjustment threshold, the supply finely adjusts the output.Type: ApplicationFiled: March 4, 2005Publication date: December 13, 2007Applicant: ARIZONA BOARD OF REGENTS, ACTING FOR AND ON BEHALF OF ARIZONA STATE UNIVERSITYInventors: Md Murshidul Islam, David Allee, Venkata Konasani, Armando Rodriguez
