A device is able to measure blood pressure from inside a user's ear. In the illustrated example, the device has three components: (1) a pulse sensor attached to an inflatable pipe which is placed inside the ear, (2) an air pump with a controller, and (3) blood pressure estimation modules including processors and computer executable instruction executed on the processors to execute blood pressure estimation algorithms.

Wearable system for frequent and comfortable blood pressure monitoring from user's ear

A computer system for intra-ear sensing and stimulating receives, health data, from an earbud sensor. The system repeatedly calculates an exponential moving average (EMA) of a moving window for the received health data. The system compares each calculated exponential moving average with a lower threshold value and an upper threshold value. The upper threshold value and the lower threshold value are determined based, at least in part, upon a saturation level associated within an amplifier performing the adaptive gain control. When the calculated exponential moving average is larger than the upper threshold, the system decreases a gain associated with the amplifier. When the calculated exponential moving average is smaller than the lower threshold, the system increases a gain associated with the amplifier.

A computer-implemented method for identifying tongue movement comprises detecting an electroencephalography ('EEG') signal from an EEG sensor. The EEG sensor is configured to sense the EEG signal generated by a brain in association with a tongue movement. The method also comprises detecting the EMG signal from the EMG sensor. The EMG sensor is configured to sense the EMG signal generated by cranial nerve stimulation of muscles associated with the tongue movement. The method also includes identifying the tongue movement based on the EEG signal and the EMG signal. The method then includes correlating the tongue movement with one of a plurality of tongue location areas.
