Publication number: 20210224524Abstract: Gait, the walking pattern of individuals, is one of the most important biometrics modalities. Most of the existing gait recognition methods take silhouettes or articulated body models as the gait features. These methods suffer from degraded recognition performance when handling confounding variables, such as clothing, carrying and view angle. To remedy this issue, a novel AutoEncoder framework is presented to explicitly disentangle pose and appearance features from RGB imagery and a long short-term memory integration of pose features over time produces the gait feature.Type: ApplicationFiled: January 22, 2021Publication date: July 22, 2021Applicants: Board of Trustees of Michigan State University, Ford Global Technologies, LLCInventors: Xiaoming LIU, Jian WAN, Kwaku PRAKAH-ASANTE, Mike BLOMMER, Ziyuan ZHANG, Luan TRAN, Xi YIN, Yousef ATOUM

Publication number: 20210196131Abstract: A method is presented for predicting onset of pulmonary congestion symptoms. The overall idea is to track rising left ventricular filling pressure (LVFP) in heart failure patients by exploiting significant changes in a pulsatile arterial waveform obtained with a mobile device and thereby avert hospitalizations. The stimulus for the changes may be metronomic deep breathing performed by the patient or a natural occurring arrhythmia such as atrial fibrillation or premature beats. For either stimulus, the extent of the amplitude variations depends on where the patient is on the Starling curve. If the patient is on the steep part of the curve, the variations will be large and LVFP will be low. If the patient is on the flatter part of the curve, the variations will be smaller and LFVP will be higher. These variations can be normalized in various ways to arrive at a congestion prediction index (CPI).Type: ApplicationFiled: May 24, 2019Publication date: July 1, 2021Applicants: Board of Trustees of Michigan State University, THE REGENTS OF THE UNIVERSITY OF MICHIGANInventors: Ramakrishna MUKKAMALA, Keerthana NATARAJAN, Mohammed SAEED
