Obstructive Sleep Apnea Episode Detection System
Summary
USPTO published patent application US20260090762A1 by inventor Hoo-Min D. Toong for an Obstructive Sleep Apnea Episode Detection System using audio frequency analysis. The system analyzes audio data during sleep to detect tongue position changes based on formant patterns, generating signals when obstructive sleep apnea episodes occur. Application No. 19413014 was filed December 9, 2025 and published April 2, 2026.
What changed
The USPTO published patent application US20260090762A1 covering an Obstructive Sleep Apnea (OSA) detection system. The system receives audio data from a sleeping user across multiple frequency bands and analyzes patterns matching vocal formants to determine tongue position in the oral cavity. When the tongue moves from a forward to rear position, indicating an OSA episode, the system generates a detection signal.
This is a published patent application, not a granted patent or regulatory requirement. Medical device companies developing sleep monitoring technologies should review the claims to assess potential infringement risks. Inventors and R&D teams may use this publication to understand prior art in audio-based sleep apnea detection. The application does not impose compliance obligations or deadlines.

Abstract
Embodiments detect obstructive sleep apnea (“OSA”) by a user. Embodiments receive audio data emanating from the user while the user is sleeping, the audio data including multiple distinct frequency bands. Embodiments analyze the audio data to detect patterns in frequency content that matches two or more formants of a plurality of formants, the two or more formants indicating a position of a tongue of the user. Based on the analyzing, embodiments determine when the tongue has moved from a forward position to a rear position in an oral cavity of the user. Embodiments generate a signal indicating an OSA episode when it is determined that the tongue has moved from a forward position to a rear position.
