The disclosure herein generally relates to the field of determination of cardiopulmonary signals for multi-persons, and, more particularly, to determination of cardiopulmonary signals for multi-persons using in-body signals obtained by ultra-wide band (UWB) radar. The disclosed method determines of cardiopulmonary signals for multi-persons using in-body signals, wherein a UWB radar signals/waves reflected from inside a human body is utilized for efficient determination of cardiopulmonary signals. The disclosed method and system utilize the UWB radar signals to identify a number of persons along with several details about the persons that include a girth of the each identified person and the orientation of the identified person towards the one or more UWB radar. Further a chest wall distance, a breathing rate, a heart wall distance and a heart rate are determined for all the identified persons based on the identified girth and the identified orientation along with the UWB radar signals.

Novel systems and methods use extracted features from audio signals of patient breathing sounds taken during periods of full wakefulness in order to classify patients as either having, or not having, obstructive sleep apnea using a Random Forest machine learning algorithm. In some embodiments, the features are preprocessed then modeled. The models with a high correlation to the response and low overlap percentages are selected for use in the Random Forest classification process.

A system and method for pairing a rider to a suitable electric transport device based on a variety of input parameters is described. The system involves a service provider that deploys at least two differently configured electric transport devices, and processes inputs from a user/rider such as biometric data, the rider's physical characteristics, rider experience level and preferences to pair the rider to a suitable electric transport device based on the inputs.

A device for measuring facial anatomical parameters is provided. The device has a vertical bar having a top portion, middle portion, and a bottom portion and a horizontal slide adjustably affixed to the vertical bar. It has a forehead positioner pivotably and adjustably affixed to the top portion of the vertical bar, wherein the forehead positioner receives a forehead of the patient, a first mirror adjustably affixed to the left portion of the horizontal slide, wherein the first mirror is slidable along the horizontal slide, and wherein the first mirror rotates around its own Y-axis, and a second mirror adjustably affixed to the right portion of the horizontal slide, wherein the second mirror is slidable along the horizontal slide. A measuring grid on or proximate both the first mirror and the second mirror, wherein the measuring grids allows an examiner to accurately measure a point of interest of the facial anatomic parameters.

A small area real-time air pollution assessment system includes a databank, a model generation module, an input module and an analysis module. In a small area real-time air pollution assessment method, the model generation module generates a model by analyzing historical tested persons' historical body characteristics data and historical air data in a plurality of monitored areas, which storing in a databank; inputs from an input module to the model a plurality of current tested persons' body characteristics data in a to-be-monitored area to generate air data corresponding to the current tested persons; selects a specified value of each of those air data and converts the specified values into air quality index values; selects a specific value of those air quality index values; and compares the specific value with an air quality health assessment table to generate assessment results. Thus, relatively accurate small area air pollution assessment results can obtainable.

Methods, systems, and computer readable media for non-invasively predicting patient-specific mechanical competence at an anatomical site. In some examples, a method includes receiving images from the anatomical site of a patient; using computational analysis of the images to simulate mechanical loading at the anatomical site; and generating, based on the analysis, an indication of stiffness, strength, resilience or toughness under the mechanical loading conditions.

A fabric material with an electrode wiring includes: a fabric material body with stretchability; a first electrode portion that is disposed on a surface or in the interior of the fabric material body, and that includes a conductive linear body; a first wiring portion that is disposed on the surface or in the interior of the fabric material body so as to be electrically connected to the first electrode portion, and that includes a conductive linear body; a second electrode portion that is disposed on the surface or in the interior of the fabric material body, and that includes a conductive linear body; and a second wiring portion that is disposed on the surface or in the interior of the fabric material body so as to be electrically connected to the second electrode portion, and that includes a conductive linear body. In the fabric material with an electrode wiring, a resistance value between the first electrode portion and the second electrode portion is varied by stretching the fabric material with an electrode wiring.

A biometric monitoring system comprises a substrate with a first surface having a length and a width. A first transmitting antenna is coupled to the first surface at a first end of the length of the first surface. A second transmitting antenna is coupled to the first surface at a second end of the length of the first surface. The first and second transmitting antennas extend across the width of the first surface. A plurality of receiving antennas are coupled to the first surface, each of which extends across the width of the substrate and is spaced apart from an adjacent receiving antenna along the length by a predetermined distance. A controller is configured to supply a first signal to the first transmitting antenna and sequentially measure a transmission coefficient or voltage of the first signal at the plurality of receiving antennas until an attenuation in the transmission coefficient or voltage exceeds a threshold.

A system and method is disclosed for measurement of pulse wave velocity of a vessel. An intravascular device comprises a first and a second marker provided at different locations along the length of the intravascular device of which positions are localizable by a tracking apparatus. The intravascular device provides plurality of measurements along the length of the vessel, while the intravascular device is moved from a first position to a second position, corresponding to a first and a second time. At the second time the position of the first marker in the vessel corresponds to the position of the second marker at the first time. The pulse wave velocity value of the vessel is ascertained based on measurements associated for the first time and the second time from the plurality of measurements and based on the distance between the locations of the two markers along the length of the intravascular device.
