Patent number: 11693113Abstract: This disclosure provides a system and method for producing ultrasound images based on Full Waveform Inversion (FWI). The system captures acoustic/(an)elastic waves transmitted through and reflected and/or diffracted from a medium. The system performs an FWI process in a time domain in conjunction with an accurate wave propagation solver. The system produces 3D maps of physical parameters that control wave propagation, such as shear and compressional wavespeeds, mass density, attenuation, Poisson's ratio, bulk and shear moduli, impedance, and even the fourth-order elastic tensor containing up to 21 independent parameters, which are of significant diagnostic value, e.g., for medical imaging and non-destructive testing.Type: GrantFiled: August 30, 2018Date of Patent: July 4, 2023Assignee: THE TRUSTEES OF PRINCETON UNIVERSITYInventors: Etienne Bachmann, Jeroen Tromp, Gregory L.

Patent number: 10535901Abstract: The invention provides an electrolyte composition which is adapted for use in a rechargeable alkaline electrochemical cell, and especially preferably adapted for use in a rechargeable manganese zinc electrochemical cell, which electrolyte composition imparts improved performance characteristics to the rechargeable alkaline electrochemical cell. The electrolyte composition includes an electrolyte composition in which contains a potassium hydroxide and lithium hydroxide in a concentration and a respective molar ratio of about 1 molar potassium hydroxide to 2.5-3.7 (preferably 1:3) molar lithium hydroxide (1 M KOH:2.5-3.7 M LiOH). Also provided are alkaline electrochemical cells and alkaline batteries comprising the electrolyte compositions. The resultant alkaline electrochemical cells and alkaline batteries exhibit improved performance characteristics, as the electrolyte composition significantly inhibits the passivation of Zn, and may also be useful in this role in other battery chemistries.Type: GrantFiled: April 5, 2016Date of Patent: January 14, 2020Assignees: THE TRUSTEES OF PRINCETON UNIVERSITY, THE REGENTS OF THE UNIVERSITY OF CALIFORNIAInventors: Daniel Steingart, Benjamin Hertzberg, Mylad Chamoun, Greg Davies, Ying Shirley Meng

Patent number: 9419289Abstract: Methods of using specific operational charge and discharge parameters to extend the life of alkaline batteries are disclosed. The methods can be used with any commercial primary or secondary alkaline battery, as well as with newer alkaline battery designs, including batteries with flowing electrolyte.

Publication number: 20070213044Abstract: In one embodiment, a wireless measurement device is provided. A wireless transceiver is configured to communicate with a base station through a wireless medium to receive configuration information. The wireless transceiver outputs a signal for use in measuring a potential or current based on the configuration information. A circuit is configured to function as a galvanostat and can receive the signal and achieve a desired current using the signal. A potential of a test cell is then measurable using the current. Also, the circuit is configured to function as a potentiostat and can achieve a desired potential using the signal. The current of the test cell is then measurable using the potential.

Publication number: 20060176175Abstract: A sensing system for sensing conditions or characteristics associated with a process or thing. The sensing system includes one or more energy converters and a sensor, which are coupled to the process or thing. A node is coupled to the sensor and the energy-converter, and the node is powered by output from the energy converter. In a more specific embodiment, the node includes a controller that implements one or more routines for selectively powering a wireless transmitter of the node based on a predetermined condition. The predetermined condition may specify that sensor output values are within a predetermined range or are below or above a predetermined threshold. Alternatively, the predetermined condition may specify that electrical energy output from the energy converter is below a predetermined threshold. A remote computer may be wirelessly connected to node and may include software and/or hardware that is adapted to process information output by the sensor and relayed to the computer via the node.Type: ApplicationFiled: January 18, 2006Publication date: August 10, 2006Applicants: The Regents of the University of California, Alcoa Technical CenterInventors: James Evans, Michael Schneider, Daniel Steingart, Paul Wright, Donald Ziegler
