Patent number: 11162925Abstract: The disclosed system and method improve analysis of chemical samples for measurement of trace volatile chemicals, such as by Gas Chromatography (GC) and Gas Chromatography/Mass Spectrometry (GCMS). The system can include two traps in series, the first of which removes most of the unwanted water vapor, while the second trap preconcentrates the sample using a series of capillary columns of increasing adsorption strength. The sample can be backflushed from the second trap directly to a chemical analyzer without splitting which can maximize sensitivity. The system improves elimination of water vapor and fixed gases from the sample prior to analysis, resulting in detection limits as low as 0.001 PPBb. The second trap allows faster release of the sample upon injection to the chemical analyzer without additional focusing, and can be cleaned up faster when exposed to high concentration samples relative to packed traps.Type: GrantFiled: October 30, 2018Date of Patent: November 2, 2021Assignee: Entech Instruments Inc.Inventor: Daniel B. Cardin

Patent number: 11085902Abstract: An optical breakdown acoustic transducer can generate high-bandwidth, high amplitude acoustic waves via an optical breakdown process. The optical breakdown acoustic transducer can include a vessel having an interior cavity that is substantially filled with a fluid and a light source that emits light. The light can be directed through an optical element that focuses the light to at least one focal point located within the fluid, thereby causing optical breakdown and generation of an acoustic shockwave. The acoustic shockwave can then be coupled into a medium surrounding the optical breakdown acoustic transducer via an acoustic outlet coupled to the vessel. The acoustic output of the optical breakdown acoustic transducer can be tuned by adjusting the properties of the optical source and/or the shape of the cavity containing the fluid. The optical breakdown acoustic transducer can be used for imaging, sensing, communication, and mechanical disruption.Type: GrantFiled: August 29, 2018Date of Patent: August 10, 2021Assignee: Massachusetts Institute of TechnologyInventor: Athanasios G.

Patent number: 10866220Abstract: In order to achieve a system capable of analyzing a wide range of compounds while saving time and energy consumption, a progressive cellular architecture is presented for vapor collection and gas chromatographic separation. Each cell includes a preconcentrator and separation column that are adapted for collecting and separating compounds only within a specific volatility range. A wide volatility range can therefore be covered by the use of multiple cells that are cascaded in the appropriate order. The separation columns within each cell are short enough to reduce the heating and pumping requirements. The gas flow for vapor collection and separation is provided by low-power gas micropumps that use ambient air. The system is also configurable to incorporate capabilities of detecting and reducing vapor overload. The progressive cellular architecture directly address the compromise between low power and broad chemical analyses.Type: GrantFiled: May 14, 2018Date of Patent: December 15, 2020Assignee: THE REGENTS OF THE UNIVERSITY OF MICHIGANInventors: Yogesh B.

Patent number: 10859448Abstract: A sensor system comprising a Micro-Electro-Mechanical Systems (MEMS)-based capacitive floating element shear stress sensor, the associated packaging, and the interface circuitry required for operation as an instrumentation-grade sensing system is disclosed herein. One implementation of the interface circuitry is an analog synchronous modulation/demodulation scheme enabling time-resolved measurements of both mean and dynamic wall shear stress events, where a modulation section couples to the sensor for sensing wall shear stress at the surface of an object in a fluid and generates at least one bias signal from the sensor output signal. In response to the bias signal, a demodulation control circuit adjusts the phase of the bias signal and generates a demodulation control signal from the phase adjusted signal. Consequently, in response to the demodulation control signal, a demodulation section synchronizes the rectification of the sensor output signal, while the phase information is maintained.Type: GrantFiled: February 11, 2016Date of Patent: December 8, 2020Assignee: University of Florida Research Foundation, IncorporatedInventors: Casey A.
