Publication number: 20240139649Abstract: Devices, systems, and techniques can be provided for processing an oil-containing material with an alcohol-based solvent to extract oil from the material. In some examples, a system includes an extractor configured to process an oil-containing feedstock. The extractor receives the oil-containing feedstock and conveys the material from an inlet to an outlet through the extractor. The extractor also receives an alcohol-based solvent at a solvent inlet and conveys the solvent through the extractor to a solvent outlet. The alcohol-based solvent may be ethanol. A concentration of oil in the feedstock may decrease as the feedstock moves through the extractor from the inlet to the outlet while the concentration of the oil in the solvent increases.Type: ApplicationFiled: February 25, 2022Publication date: May 2, 2024Inventors: Wade Steven Martinson, Benjamin Wayne Floan, Nicholas Ollila, Jeff Garritsen, Austin Nelson

Patent number: 11971387Abstract: The subject disclosure presents systems and computer-implemented methods for determining an acoustic time-of-flight (TOF) of sound waves through a sample material with greater accuracy and in a more repeatable fashion, by invoking one or more of an envelope generation for an error function, fitting a non-linear curve to an ultrasound frequency sweep, or performing a clustered piece-wise linear regression on individual linear parts of the ultrasonic frequency sweep. The systems and methods are useful for, among other things, monitoring diffusion of fluids through porous materials, such as tissue samples.Type: GrantFiled: April 13, 2021Date of Patent: April 30, 2024Assignee: VENTANA MEDICAL SYSTEMS, INC.Inventors: Daniel Bauer, Michael Otter, Benjamin Stevens

Publication number: 20240066431Abstract: Systems and techniques can be used to extract solid material with an alcohol-based solvent. To subsequently recover the solvent after extraction, the solvent-wet solid material having undergone extraction can be desolventized. The solvent-wet solid material may be desolventized in multiple stages, either in a single vessel or in multiple different vessels, to generate multiple corresponding condensate streams containing alcohol and water vaporized from the solvent-wet solid material. By splitting desolventization into multiple stages, the composition of the condensate streams generated during desolventization can be individually controlled to benefit downstream processing. For example, the first condensate stream produced during desolventization may have a comparatively low amount of water whereas a second condensate stream produced during desolventization may have a comparatively high amount of water.Type: ApplicationFiled: August 24, 2023Publication date: February 29, 2024Inventors: Nicholas Ollila, Wade Steven Martinson, Benjamin Wayne Floan, Aaron Iwen

Patent number: 11727033Abstract: Systems and methods for presenting CRM data. Users may configure what to display on a custom report and how to arrange and display the content (e.g., size, color, theme), so that they can visualize the CRM data the way they want. A data visualization interface may be used to generate the custom report, and may use HTML to specify the CRM data to be displayed and their location on the custom report according to user configuration. The data visualization interface may use JavaScript for specifying the objects and fields users want to query to obtain the CRM data to fill up the custom report. An API may communicate with the JavaScript in the data visualization interface and then query data and objects in the CRM to get a result set. The API may be a unified API which may work across multiple platforms and query various types of database, e.g., iOS, Windows, and the browser for Salesforce online. Users may edit the CRM data displayed in the custom report.Type: GrantFiled: November 6, 2020Date of Patent: August 15, 2023Assignee: Veeva Systems Inc.Inventors: Benjamin Steven Thomas, Povilas Petkevicius, Ryan Andrew Brennan

Patent number: 11002593Abstract: The subject disclosure presents systems and computer-implemented methods for calculating the diffusivity constant of a sample using acoustic time-of-flight (TOF) based information correlated with a diffusion model to reconstruct a sample's diffusivity coefficient. Operations disclosed herein such as acoustically determining the phase differential accumulated through passive fluid exchange (i.e. diffusion) based on the geometry of the tissue sample, modeling the impact of the diffusion on the TOF, and using a post-processing algorithm to correlate the results to determine the diffusivity constant, are enabled by monitoring the changes in the speed of sound caused by penetration of fixative such as formalin into several tissue samples. A tissue preparation system may be adapted to monitor said diffusion of a tissue sample and determine an optimal processing workflow.Type: GrantFiled: February 27, 2020Date of Patent: May 11, 2021Assignee: Ventana Medical Systems, Inc.Inventors: Daniel Bauer, Michael Otter, Benjamin Stevens
