Patent number: 12207933Abstract: The present invention relates to a physiological monitor and system, more particularly to an electroencephalogram (EEG) monitor and system, and a method of detecting the presence and absence of artifacts and possibly removing artifacts from an EEG, other physiological signal or sensor signal without corrupting or compromising the signal. The accurate and real-time detection of the presence or absence of artifacts and removal of artifacts in an EEG or other signal allows for increased reliability in the efficacy of those signals. The strategy of rejecting artifact-corrupted EEG can result in unacceptable data loss, and asking subjects to minimize movements in order to minimize artifacts is not always feasible. The present invention allows for increased accuracy in detection and removal of artifacts from physiological signals, substantially in real time, and without the loss or corruption of signal or data in order to increase the accuracy of such signals for diagnosis and treatment purposes.Type: GrantFiled: January 8, 2021Date of Patent: January 28, 2025Assignee: NeuroWave Systems Inc.Inventors: Niranjan Chakravarthy, Stèphane Bibian, Tatjana Zikov

Patent number: 12121369Abstract: The invention provides a neck-worn sensor that is a single, body-worn system that measures the following parameters from an ambulatory patient: heart rate, pulse rate, pulse oximetry, respiratory rate, temperature, thoracic fluid levels, stroke volume, cardiac output, and a parameter sensitive to blood pressure called pulse transit time. From stroke volume, a first algorithm employing a linear model can estimate the patient's pulse pressure. And from pulse pressure and pulse transit time, a second algorithm, also employing a linear algorithm, can estimate systolic blood pressure and diastolic blood pressure. Thus, the sensor can measure all five vital signs along with hemodynamic parameters. It also includes a motion-detecting accelerometer, from which it can determine motion-related parameters such as posture, degree of motion, activity level, respiratory-induced heaving of the chest, and falls.Type: GrantFiled: April 30, 2021Date of Patent: October 22, 2024Assignees: BAXTER INTERNATIONAL INC., BAXTER HEALTHCARE SAInventors: Matthew Banet, Kenneth Robert Hunt, Marshal Singh Dhillon, Susan Meeks Pede
