Real-time estimation of human core body temperature based on non-invasive physiological measurements
Patent number: 11540723Abstract: A method of estimating a body temperature of an individual based on physiological data including a heart rate received from at least one sensor 510 and received environmental data. The physiological data and the environmental data are inputted into a model present on a processor 520. The model generates an estimated body temperature and an estimated physiological condition based on the inputs. The processor 520 compares the estimated physiological condition to a measured physiological condition in the physiological data. A controller 530 modifies at least one parameter in the model when the difference between the estimated physiological condition and the measured physiological condition is above a threshold.Type: GrantFiled: September 28, 2020Date of Patent: January 3, 2023Assignee: The Government of the United States as represented by the Secretary of the ArmyInventors: Jaques Reifman, Srinivas Laxminarayan, Vineet Rakesh, Sridhar Ramakrishnan, Jianbo Liu -

Patent number: 6519535Abstract: A signal processing technique which correlates eddy current inspection data from a tube having a critical tubing defect with a range of predicted burst pressures for the tube is provided. The method can directly correlate the raw eddy current inspection data representing the critical tubing defect with the range of burst pressures using a regression technique, preferably an artificial neural network. Alternatively, the technique deconvolves the raw eddy current inspection data into a set of undistorted signals, each of which represents a separate defect of the tube. The undistorted defect signal which represents the critical tubing defect is related to a range of burst pressures utilizing a regression technique.Type: GrantFiled: June 5, 2000Date of Patent: February 11, 2003Assignee: The University of ChicagoInventors: Mark C.

Patent number: 5930315Abstract: A process management expert system where following malfunctioning of a component, such as a pump, for determining system realignment procedures such as for by-passing the malfunctioning component with on-line speeds to maintain operation of the process at full or partial capacity or to provide safe shut down of the system while isolating the malfunctioning component. The expert system uses thermal-hydraulic function classes at the component level for analyzing unanticipated as well as anticipated component malfunctions to provide recommended sequences of operator actions. Each component is classified according to its thermal-hydraulic function, and the generic and component-specific characteristics for that function. Using the diagnosis of the malfunctioning component and its thermal hydraulic class, the expert system analysis is carried out using generic thermal-hydraulic first principles.Type: GrantFiled: December 12, 1997Date of Patent: July 27, 1999Assignee: The United States of America as represented by the United States Department of EnergyInventors: James A.

Patent number: 5442555Abstract: A two-level hierarchical approach for process fault diagnosis is an operating system employs a function-oriented approach at a first level and a component characteristic-oriented approach at a second level, where the decision-making procedure is structured in order of decreasing intelligence with increasing precision. At the first level, the diagnostic method is general and has knowledge of the overall process including a wide variety of plant transients and the functional behavior of the process components. An expert system classifies malfunctions by function to narrow the diagnostic focus to a particular set of possible faulty components that could be responsible for the detected functional misbehavior of the operating system. At the second level, the diagnostic method limits its scope to component malfunctions, using more detailed knowledge of component characteristics.Type: GrantFiled: October 7, 1993Date of Patent: August 15, 1995Assignee: Argonne National LaboratoryInventors: Jaques Reifman, Thomas Y.
