The PSM includes a controller comprising a sensing face, an intermediary circuit, and a mounting face. The controller provides a sensor array of specified biosensors. The controller is mountable with an ECG patch. The PSM includes an ECG patch coupled with the controller. The controller is removably mounted via comprising a sensor patch comprising a flat piece of material with an array of sensors arranged on a sensing face of the sensor patch of the sensor patch that is designed with a receptacle to which the controller device is connected into the ECG patch. The ECG patch obtains an ECG data o the user that is passed to the controller. The controller electronically communicates the ECG data and the specified biosensor data to the PHI server. The PHI server queries one or more health provider records systems to obtain a set of electronic health records, of the user. The PHI server electronically communicates the set of electronic health records to a system control program (SCP) server. The SCP server uses the biosensor data collected by the PSM, along with the PHI from electronic health records, to construct a virtual model of an individual's quantifiable biological markers in real time.

Abstract: A multi-channel real-time cardiovascular performance evaluation system, includes: a multi-channel ECG signals measurement unit, a multi-channel ECG signals processing device, and an ECG signals reconstruction unit. The method uses a MAMA-END algorithm, to mark ECG signals to replace the original ECG signal, and to extract characteristic peak value of the ECG signal. As such, the method is able to extract and reconstruct a first signal having QRS wave, and a second signal having T wave; then the method detects and marks the start of Q wave and the end of T wave on the first signal and the second signal. Therefore, the method is able to determine and evaluate if a patient does have cardiovascular disease, and to locate the lesion positions of a patient having cardiovascular disease.

Abstract: A process of capturing a biopotential signal at a surface of a body includes using a sensor receiver which forms a first signal connection with the body wherein one or more parameters of impedance of the first signal connection are unknown. The biopotential signal is received at an output of a first signal channel having a first transfer function dependent on the one or more unknown first impedance parameters. The biopotential signal is received at an output of a second signal channel having a second transfer function dependent on the one or more unknown first impedance parameters. The process also comprises deriving a set of relations for the biopotential signal based on the transfer function of the first signal channel, the transfer function of the second signal channel, and outputs of the first and second signal channels. The set of relations is solved to determine the captured biopotential signal.

Abstract: A system includes signal acquisition circuitry and a processor. The signal acquisition circuitry is configured to receive multiple intra-cardiac signals acquired by multiple electrodes of an intra-cardiac probe in a heart of a patient. The processor is configured to perform a sequence of annotation-visualization operations at subsequent times, by performing, in each operation: extracting multiple annotation values from the intra-cardiac signals, selecting a group of the intra-cardiac signals, identifying in the group one or more annotation values that are statistically deviant by more than a predefined measure of deviation, and visualizing the annotation values to a user, while omitting and refraining from visualizing the statistically deviant annotation values. The processor is further configured to assess, over one or more of the annotation-visualization operations, a rate of omissions of annotation values, and to take a corrective action in response to detecting that the rate of omissions exceeds a predefined threshold.
