Publication number: 20200178814Abstract: The invention provides a body-worn monitor that measures a patient's vital signs (e.g. blood pressure, SpO2, heart rate, respiratory rate, and temperature) while simultaneously characterizing their activity state (e.g. resting, walking, convulsing, falling).

Publication number: 20200178847Abstract: Described is a device for determining gestational age and methods for determining gestational age at birth by measuring parameters associated with photobiological properties of the skin such as reflectance or reflectivity by measuring diffused or scattered portions of the light beam incident on the skin, as well as the erythema index, along with clinical parameters of the newborn such as gender, the use of phototherapy, birth weight and time spent in incubator. The ability to obtain a realistic estimate of the age of the conceptus quickly, non-invasively and at low cost makes it possible to provide care suited to the needs of the newborn, to assess the chances of survival and to affect the short- and long-term prognosis of the newborn. The correct determination of gestational age at birth also influences clinical follow-up protocols in infancy and vital statistics.Type: ApplicationFiled: November 1, 2017Publication date: June 11, 2020Inventors: Zilma SILVEIRA NOGUEIRA REIS, Rodney NASCIMENTO GUIMARÃES

Publication number: 20200178849Abstract: A method and system for heterogeneous event detection. Sensor data is obtained and divided into discrete data windows. Each data window is defined by and corresponds to a time period of the sensor data. A time-frequency representation over the time period is calculated for each data window. A filter mask is calculated based on the data window corresponding to the time-frequency representation. The filter mask is applied for reverting the time-frequency representation to a time representation, resulting in filtered data. Features, such as extrema or other inflection points, are identified in the filtered data. The features define events, and transforming the time-frequency representation back into the time domain emphasizes differences between more and less prominent frequencies, facilitating identification of heterogeneous events. The method and system may be applied to body movements of people or animals, automaton movement, audio signals, light intensity, or any suitable time-dependent variable.Type: ApplicationFiled: June 28, 2018Publication date: June 11, 2020Applicant: ORPYX MEDICAL TECHNOLOGIES INC.Inventors: CHUN HING CHENG, MICHAEL TODD PURDY, TRAVIS MICHAEL STEVENS

Publication number: 20200178850Abstract: This document discusses, among other things, systems and methods to determine an indication of heart failure with preserved ejection fraction (HFpEF) of a subject using a determined change in cardiac acceleration information of the subject at exertion relative to cardiac acceleration information of the subject at rest. The system can include a signal receiver circuit configured to receive cardiac acceleration information of a subject and exertion information of the subject, and an assessment circuit configured to determine the change in cardiac acceleration information of the subject at exertion relative to cardiac acceleration information of the subject at rest, and to determine an indication of HFpEF of the subject using the determined change in cardiac acceleration information.Type: ApplicationFiled: December 10, 2019Publication date: June 11, 2020Inventors: Pramodsingh Hirasingh Thakur, Bin Mi

Publication number: 20200178851Abstract: A system for tracking body movement can comprise a first markerless sensor, a second markerless sensor, a processor, and a memory. The first markerless sensor can be configured to generate a first set of data indicative of positions of at least a portion of a body over a period of time. The second markerless sensor can be configured to generate a second set of data indicative of positions of the at least a portion of the body over the period of time. The memory can comprise logical instructions that, when executed by the processor, cause the processor to generate a third set of data based on the first and second sets of data. The third set of data can be indicative of estimates of at least one of joint positions and joint angles of the at least a portion of the body over the period of time.Type: ApplicationFiled: July 10, 2018Publication date: June 11, 2020Inventors: William Singhose, Franziska Schlagenhauf
