Abstract: A respiratory sensor system provides the ability to determine a respiration rate. The respiratory sensor system may include a respiratory sensor and a software solution, where the software solution determines respiration rate from the respiratory sensor (e.g., microphone) located on the bridge of the user's nose. The respiratory sensor may be placed on or near the nose, such as a microphone located in the nosepiece of a pair of glasses. Due to the placement of the microphone and the respiration detection system design, the wearer respiration rate can be determined reliably even with ambient noise and movement. This makes the respiration rate calculation accessible and reliable, both for everyday wear and for extreme situations such as sports.

Abstract: An example apparatus for detecting respiratory rates includes an audio receiver to receive audio including respiratory sounds. The apparatus also includes an adaptive low-pass filter to process the audio using an adaptive bandwidth based on a mean breath rate to generate an envelope. The apparatus further includes a peak detector to detect a plurality of peaks from the envelope. The apparatus includes a respiratory rate calculator to calculate a respiratory rate based on the detected plurality of peaks.

Abstract: Embodiments of the present disclosure provide techniques and configurations for an apparatus for stress event detection. In some embodiments, the apparatus may be a wearable device and may include at least one first sensor disposed on the wearable apparatus to generate a first sensor signal indicative of a brain activity of a user, at least one second sensor disposed on the wearable apparatus to generate a second sensor signal indicative of a heart rate of the user, and at least one third sensor disposed on the wearable apparatus to generate a third sensor signal indicative of a respiration rate of the user. The apparatus may further include a controller coupled with the at least first, second, and third sensors, to detect a stress event for the user, based at least in part on the first, second, and third sensor signals. Other embodiments may be described and/or claimed.
