Patent number: 11867713Abstract: An optomechanical inertial reference mirror combines an optomechanical resonator with a reflector that serves as an inertial reference for an atom interferometer. The optomechanical resonator is optically monitored to obtain a first inertial measurement of the reflector that features high bandwidth and high dynamic range. The atom interferometer generates a second inertial measurement of the reflector that features high accuracy and stability. The second inertial measurement corrects for drift of the first inertial measurement, thereby resulting in a single inertial measurement of the reflector having high bandwidth, high dynamic range, excellent long-term stability, and high accuracy. The reflector may be bonded to the resonator, or formed directly onto a test mass of the resonator. With a volume of less than one cubic centimeter, the optomechanical inertial reference mirror is particularly advantageous for portable atomic-based sensors and systems.Type: GrantFiled: February 15, 2020Date of Patent: January 9, 2024Assignees: Arizona Board of Regents on Behalf of The University of Arizona, Leibniz Universität HannoverInventors: Felipe Guzmán, Ernst Maria Rasel, Dennis Schlippert

Patent number: 11868479Abstract: A security framework for life-critical and safety-critical devices, specifically medical devices, using: a) runtime, adaptive methods that dynamically assess the risk of newly discovered vulnerabilities and threats, and b) automatic mitigation methods that reduce system risk by seamlessly reconfiguring the device to operate within different execution modes. This technology automatically isolates threats by disabling affected system components. A multi-modal software design uses adaptive software in which operational modes have monotonically decreasing cumulative risk. Formal risk models are used to model the individual risk of accessing or controlling system components and to automatically calculate the cumulative risk of software modes. The automated detection of potential threats by the system or reporting of known vulnerabilities will dynamically change the system risk.Type: GrantFiled: November 1, 2019Date of Patent: January 9, 2024Assignees: ARIZONA BOARD OF REGENTS ON BEHALF OF THE UNIVERSITY OF ARIZONA, JOHANNES KEPLER UNIVERSITY LINZInventors: Roman Lysecky, Jerzy Rozenblit, Johannes Sametinger, Aakarsh Rao, Nadir Carreon

Patent number: 11867644Abstract: Methods and systems are provided for serial femtosecond crystallography for reducing the vast amount of waste of injected crystals practiced with traditional continuous flow injections. A micrometer-scale 3-D printed water-in-oil droplet generator device includes an oil phase inlet channel, an aqueous phase inlet channel, a droplet flow outlet channel, and two embedded non-contact electrodes. The inlet and outlet channels are connected internally at a junction. The electrodes comprise gallium metal injected within the 3-D printed device. Voltage across the electrodes generates water-in-oil droplets, determines a rate for a series of droplets, or triggers a phase shift in the droplets. An external trigger generates the droplets based on the frequency of an XFEL utilized in droplet detection, thereby synchronizing a series of droplets with x-ray pulses for efficient crystal detection. The generated droplets can be coupled to an SFX with XFEL experiment compatible with common liquid injector such as a GDVN.Type: GrantFiled: April 1, 2021Date of Patent: January 9, 2024Assignee: ARIZONA BOARD OF REGENTS ON BEHALF OF ARIZONA STATE UNIVERSITYInventors: Alexandra Ros, Daihyun Kim, Austin Echelmeier, Jorvani Cruz Villarreal, Ana Egatz-Gomez, Sebastian Quintana

Publication number: 20240005976Abstract: A Processing-in-Memory (PIM) design is disclosed that converts any memory sub-array based on non-volatile resistive bit-cells into a potential processing unit. The memory includes the data matrix stored in terms of resistive states of memory cells. Through modifying peripheral circuits, the address decoder receives three addresses and activates three memory rows with resistive bit-cells (i.e., data operands). In this way, three bit-cells are activated in each memory bit-line and sensed simultaneously, leading to different parallel resistive levels at the sense amplifier side. By selecting different reference resistance levels and a modified sense amplifier, a full-set of single-cycle 1-/2-3-input reconfigurable complete Boolean logic and full-adder outputs could be intrinsically readout based on input operand data in the memory array.Type: ApplicationFiled: August 11, 2022Publication date: January 4, 2024Applicant: Arizona Board of Regents on behalf of Arizona State UniversityInventors: Deliang Fan, Shaahin Angizi
