Patent number: 11360010Abstract: A low-cost, magnetically-driven device that enables visualization and quantification of dynamic changes in cell behavior during mechanical stretch. Using this device, it was observed that nuclei of mouse embryonic skin fibroblasts underwent rapid but divergent responses to strain magnitude, showing nuclear area increase and chromatin decompaction during 5% (low) strain, but nuclear area decrease and chromatin condensation during 20% (high) strain. Only responses to low strain were dependent on calcium, while actin inhibition abrogated any nuclear response and increased stretch-induced DNA damage. Stretch-activation revealed a shift in actin filaments away from (low strain) or towards (high strain) the nuclear periphery. The findings suggest that different pathways control strain level-dependent cell behavior and that mechanical confinement of nuclei through actin may be a protective mechanism during high strain loads.Type: GrantFiled: July 20, 2020Date of Patent: June 14, 2022Assignee: The Regents of the University of Colorado, a body corporateInventors: Corey P.

Patent number: 10828444Abstract: A medical ventilator (10) performs a method including: receiving measurements of pressure of air inspired by or expired from a ventilated patient (12) operatively connected with the medical ventilator; receiving measurements of air flow into or out of the ventilated patient operatively connected with the medical ventilator; dividing a breath time interval into a plurality of fitting regions (60); and simultaneously estimating respiratory system's resistance and compliance or elastance, and respiratory muscle pressure in each fitting region by fitting to a time series of pressure and air flow samples in that fitting region. In one approach, the fitting includes parameterizing the respiratory muscle pressure by a continuous differentiable function, such as a polynomial function, over the fitting region.Type: GrantFiled: January 12, 2016Date of Patent: November 10, 2020Assignee: Koninklijke Philips N.V.Inventors: Antonio Albanese, Francesco Vicario, Dong Wang, Nikolaos Karamolegkos, Nicolas Wadih Chbat

Patent number: 10775222Abstract: A measurement module determines a fluid quantity which relates to a property of a fluid located in or flowing through a measurement tube. The measurement module contains a base body, a control device and first and second oscillation transducers fastened at a distance from one another on the base body. The first and/or the second oscillation transducer is controlled by the control device to excite an oscillation of a side wall of the measurement tube when a contact face of the measurement module is coupled to the side wall of the measurement tube directly or via a coupling layer. The oscillation of the side wall excites compression oscillations of the fluid, which are conducted through the fluid to the respective other oscillation transducer and recorded the control device to determine a measurement quantity. The fluid quantity can be determined by the control device in dependence on the measurement quantity.Type: GrantFiled: July 3, 2018Date of Patent: September 15, 2020Assignee: Diehl Metering GmbHInventors: Peter Ploss, Michael Mayle

Patent number: 10588550Abstract: A method, apparatus, and system for measuring respiratory effort of a subject are provided. A thorax effort signal and an abdomen effort signal are obtained. The thorax effort signal and the abdomen effort signal are each divided into a volume-contributing component of the respiratory effort and a paradox component. The paradox component represents a non-volume-contributing component of the respiratory effort. The abdomen paradox component is negatively proportional to the thoracic paradox component. The thorax effort signal or the abdomen effort signal or both are weighted by a weight factor to obtain a volume-proportional signal. The volume-proportional signal is proportional to the actual respiratory volume of the respiratory effort. A calibration factor for calibrating the thorax effort signal and the abdomen effort signal is obtained by optimizing the weight factor by minimizing thoracic paradox component and the abdomen paradox component.Type: GrantFiled: November 6, 2014Date of Patent: March 17, 2020Assignee: NOX MEDICALInventors: Sveinbjorn Hoskuldsson, Haraldur Tomas Hallgrimsson, Gudjon Teitur Sigurdarson
