Fatigue monitoring system using sleep and breathing data
The patent US12070325B2 describes a sophisticated system designed to monitor sleep disordered breathing in users. This system integrates sensing apparatus that generates both movement and audio signals to gather comprehensive sleep information. The processors within the system are tasked with detecting snoring events from the audio signal and obtaining sensor data related to respiratory movement and sleep measures. A key feature of the system is its ability to generate sleep disordered breathing measures based on detected snoring events while also rejecting non-user snoring sounds by correlating audio signals with sensor data. This ensures that the system accurately identifies and analyzes the user's sleep patterns.
Additionally, the patent outlines various methods and configurations to enhance the accuracy of snoring detection. For instance, it specifies that snoring measures are only considered when the user is present and asleep, and it can exclude non-snoring sounds. The system can also apply voice recognition features to suppress false snoring detections and correlate snoring patterns with apnea and hypopnea events. Furthermore, it is designed to operate effectively in environments with multiple sleeping individuals by determining correlations between audio and movement signals to isolate the user's snoring. Overall, this patent presents a comprehensive approach to monitoring and analyzing sleep disordered breathing, leveraging advanced signal processing techniques to improve accuracy and reliability.
