Publication number: 20230355173Abstract: A monitoring apparatus for a human body includes a node network with at least one motion sensor and at least one acoustic sensor. A processor is coupled to the node network, and receives motion information and acoustic information from the node network. The processor determines from the motion information and the acoustic information a source of acoustic emissions within the human body by analyzing the acoustic information in the time domain to identify an event envelope representing an acoustic event, determining a feature vector related to the event envelope, calculating a distance between the feature vector and each of a set of predetermined event silhouettes, and identifying one of the predetermined event silhouettes for which the distance is a minimum.Type: ApplicationFiled: July 12, 2023Publication date: November 9, 2023Applicant: THE REGENTS OF THE UNIVERSITY OF CALIFORNIAInventors: Fabrizio BILLI, Per Henrik BORGSTROM, William KAISER, Harry A. MCKELLOP

Publication number: 20230329563Abstract: A non-invasive, passive, and fully automated heart-sound-based system and method that provides estimates for blood velocity, tissue motion, and cardiac chamber size parameters for cardiac assessment is provided. The system uses a computer processor and software to receive PCG acoustic signals from one or more sensors and simultaneously receive electrocardiogram (ECG) signals from one or more sensors that are attached to a patient. The phonocardiogram (PCG) processing system and methods compute proxy metrics for echocardiographic parameters of cardiac tissue motion and valvular blood flow for evaluation.Type: ApplicationFiled: April 14, 2023Publication date: October 19, 2023Applicants: THE REGENTS OF THE UNIVERSITY OF CALIFORNIA, SENSYDIA CORPORATIONInventors: Kanav Saraf, Per Henrik Borgstrom, Christopher Inhwan Baek, Michael Wasko, Yi Zheng, Xu Zhang, William J. Kaiser, Aman Mahajan

Publication number: 20220304631Abstract: Systems and methods are provided for the non-invasive computation of Pulmonary Artery Pressure (and its components of mean, systolic and diastolic) (PAP) as well as Pulmonary Capillary Wedge Pressure (and its components of mean, A-Wave and V-Wave) (PCWP) using a wearable sensor device. Cardiac acoustic and electrocardiogram sensor signals are obtained and multiple temporal, amplitude-based, and spectral features are extracted from the signals. Extracted features from a subject are used as inputs for pre-trained classification, regression, or advanced machine learning models to provide an accurate computation of PAP and PCWP and their associated component values without surgery.Type: ApplicationFiled: March 29, 2021Publication date: September 29, 2022Applicants: THE REGENTS OF THE UNIVERSITY OF CALIFORNIA, SENSYDIA CORPORATIONInventors: William J. Kaiser, Christopher Baek, Per Henrik Borgstrom, Aman Mahajan, Kanav Saraf, Michael Wasko, Xu Zhang, Yi Zheng
