Abstract

Methods, systems, and computer-readable media for synchronizing physiological signals collected from two or more physiological sensors are provided. Examples of physiological signals may include respiration, heartbeat, electroencephalogram, and gastrointestinal signals. A method, an apparatus, and a computer program for synchronizing two or more physiological signals may involve collecting first data from a first sensor and second data from a second sensor, each of the first data and the second data represents a plurality of physiological signal components; extracting a common physiological signal component of the first data and the second data; correlating the common physiological signal component of the plurality of physiological signal components of the first data and of the plurality of physiological signal components of the second data; and based on the correlating, synchronizing a first physiological signal component included in the first data and a second physiological signal component included in the second data.

Description

Background technique [0001] In some applications, physiological signals are collected from two or more sensors. The process of aligning these signals with each other is called synchronization. Synchronization of physiological data collected by different sensors is important because it can ensure accuracy of processing for applications that use or require physiological signals from different sensors. [0002] Proper implementation of processing physiological signals from different sensors can be challenging due to differences in sensitivity, response time, communication channel latency, etc. of each sensor. Attaching time stamps or other information or signals generated for the purpose of synchronizing the physiological signals requires additional equipment and / or resources. In some applications, it is not feasible to generate signals for synchronizing physiological signals. For example, the generated signals may interfere with physiological signals or the normal function of...
