Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing health monitoring devices often operate with unsynchronized internal clocks, making it challenging to synchronize physiological signals across different devices, particularly those from different manufacturers, which hinders accurate processing of shared health metrics.
Innovation Solution
A system and method for synchronizing physiological signals from multiple monitoring devices by determining time markers through signal feature correlation and setting anchor points to resample signals, aligning them to a common time-base.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If multiple separate health monitoring devices are used to collect physiological signals, then the quantity and variety of health metrics improve, but the synchronization accuracy of signals across devices deteriorates due to unsynchronized internal clocks
Solution Approach 1:
The patent introduces a synchronization signal as an intermediary element that is transmitted between multiple health monitoring devices. This synchronization signal contains timing information that allows each device to align its internal clock with a common time reference, thereby resolving the timestamp mismatch problem while maintaining the use of multiple separate devices for collecting diverse physiological signals
2Adaptability or versatility
If devices from different manufacturers with different operating specifications are integrated, then the versatility of the health monitoring system improves, but the difficulty of synchronizing signals increases
Solution Approach 1:
The patent implements a universal synchronization protocol that can be applied across different device types and manufacturers. The synchronization signal is designed to be device-agnostic, allowing multiple heterogeneous devices to participate in the same synchronized network without requiring device-specific synchronization mechanisms, thus maintaining versatility while reducing synchronization complexity
3Productivity
If physiological signals are processed without synchronization, then the processing speed improves, but the accuracy of shared signal analysis deteriorates
Solution Approach 1:
The patent applies timestamp correction as a preliminary action before signal processing. By adjusting the timestamps of physiological signals to account for device clock differences before analysis, the system maintains processing speed while ensuring that subsequent shared signal analysis operates on accurately synchronized data, thereby improving analysis accuracy without sacrificing productivity

AI summary
Health monitoring systems and methods configured to synchronize separate monitoring devices for accurate processing of shared signals are provided. While the use of health monitoring devices is increasing in popularity and a growing number of devices are becoming available, each of these devices can have different manufacturers and operating specifications. As such, data collected across devices cannot be readily integrated. In accordance with the present disclosure, the systems and methods provided enable the synchronization of multiple health monitoring devices using only a physiological signal measured by two or more of the devices.
