Abstract: A balance detection and correction system includes at least one sensor positioned in an ear of a user, a processor, and a memory having instructions stored thereon that, when executed by the processor, causes the processor to perform operations including continuously tracking a position of the user’s head based on first data obtained from the first sensor, comparing the position of the user’s head to second data obtained from a second sensor positioned on the user’s body to detect an imbalance in the user’s posture or movements, and initiating a response action responsive to the detection of an imbalance.

Abstract: A face mask includes a mask body formed of a flexible material and configured to cover the mouth and nose of the user such that a cavity is formed between the face of the user and the face mask, the mask body having an interior surface facing the mouth and nose of the user and an exterior surface opposite the interior surface; a first sensor unit for measuring a moisture level and an oxygen level of the air entering the cavity; a second sensor unit for measuring a moisture level and an oxygen level of the air being expelled from the cavity; and at least one wireless transceiver configured to transmit data from the first sensor unit and the second sensor unit to a remote device.

Abstract: A wearable audio device includes a speaker, a wireless communications interface, an audio sensor configured to capture ambient noise in an environment occupied by a user wearing the wearable audio device, and memory having instructions stored thereon that, when executed by one or more processors, cause the one or more processors to perform operations including receiving, via the wireless communications interface, a first user input identifying a frequency range to be attenuated, generating an audio signal from the captured ambient noise, attenuating the audio signal to reduce an amplitude of one or more frequency components based on the frequency range, and causing the speaker to produce sound based on the attenuated audio signal.
