Abstract: An respirator}′ failure detection system and associated devices and methods are disclosed herein. In one embodiment, one or more transducers of a mobile device emit acoustic energy toward a subject and acquire a corresponding reflected signal. In some embodiments, the system analyzes the reflected signal to determine a distance between the subject and the mobile device. The system extracts motion data of the subject from the reflected signal. Based at least in part on the extracted motion data, the system identifies gross motor motion of the subject and/or determines one or more breathing parameters of the subject. In some embodiments, the system uses the breathing parameters to determine whether the subject is currently in need of rescue intervention. When the subject is currently in need of rescue intervention, the system can solicit help from emergency services, contact an emergency contact specified by the subject, and/or administer an antidote.

Abstract: Embodiments of the present disclosure provide systems and methods directed to contactless motion tracking. In operation, a speaker may provide an acoustic signal to, for example, a subject. A microphone array may receive a reflected acoustic signal, where the received reflected signal is responsive to the acoustic signal reflecting off the subject. A computing device may extraction motion data of the subject based on the received reflected acoustic signal. Various motion data extraction methods are described herein. The motion data may include respiration motion, coarse movement motion, respiration rate, and the like. Using the extracted motion data, the processor may identify at least one health condition and/or sleep anomaly corresponding to the subject. In some examples, beamforming is implemented to aid in contactless motion tracking.

Abstract: Examples of systems and methods described herein may classify agonal breathing in audio signals produced by a user using a trained neural network. Examples may include a smart device that may request medical assistance if an agonal breathing event is classified.
