Patent number: 11346718Abstract: A freeform imaging system with a spectrometer and telescope components optically connected and optimized to increase the spectral and spatial resolution capabilities. Many embodiments of the system are capable of producing a spectral resolution of approximately 1 nm and a spatial resolution less than 30 m such that the imaging system can be used to accurately capture and measure point source plumes of various atmospheric gases including CH4, CO2, CO, N2O, and H2O.Type: GrantFiled: October 21, 2019Date of Patent: May 31, 2022Assignee: California Institute of TechnologyInventors: Andrew K. Thorpe, Robert O. Green, Pantazis Mouroulis, David R. Thompson, Andrew D. Aubrey, Christian Frankenberg

Patent number: 11346501Abstract: A hydrogen storage tank for a hydrogen fueled aircraft. The tank has a wall made of layers of aerogel sections around a hard shell layer, sealed within a flexible outer layer, and having the air removed to form a vacuum. The periphery of each layer section abuts other sections of that layer, but only overlies the periphery of the sections of other layers at individual points. The wall is characterized by a thermal conductivity that is lower near its gravitational top than its gravitational bottom. The tank has two exit passageways, one being direct, and the other passing through a vapor shield that extends through the wall between two layers of aerogel. A control system controls the relative flow through the two passages to regulate the boil-off rate of the tank.Type: GrantFiled: March 6, 2020Date of Patent: May 31, 2022Assignee: AeroVironment, Inc.Inventors: Alexander N. Brooks, Bart D. Hibbs, David R. Thompson

Patent number: 9228975Abstract: Verification of patient sample electrolyte results using a separate quantitative measurement of sample resistivity. Sample resistivity may be used to measure small differences in resistivity of one sample to the next, and in comparison to a standard solution, in order to verify the results of sample electrolyte measurements being measured at the same time by, for example, individual ion selective electrodes (ISE) in a clinical analyzer. Providing a separate or secondary quantitative means for verification of the measured results of sample electrolytes using sample resistivity solves the problem of electrolyte result variability in sample electrolyte measurements. The process may compare a measured sample resistivity to an expected resistivity value as a verification of the accuracy of individual electrolyte results. Suspect samples—e.g., where the electrolyte resistivity results do not fit the expected resistivity—may be flagged.Type: GrantFiled: August 24, 2012Date of Patent: January 5, 2016Assignee: Siemens Healthcare Diagnostics Inc.Inventor: David R.

Patent number: 8328909Abstract: Solid adsorbents, following their use for mercury removal from flue gas, that do not interfere with the ability of air-entraining additives (such as surfactants) to form stable bubbles when added to fly ash containing the adsorbents. The interference is overcome by heating the materials used in the manufacture of the adsorbent so that magnesium hydroxide and/or one or more alkali compounds containing one or more silicate, aluminate, and/or phosphate moiety, added or already present in the materials, binds multivalent cations present in the materials that could otherwise interfere with the surfactant activity.Type: GrantFiled: May 27, 2010Date of Patent: December 11, 2012Assignee: Praxair Technology, Inc.Inventors: Chien-Chung Chao, David R.
