The wearing section has a second end provided with a pressing portion configured to be pressed against a skin of a rear neck opposite a right front neck with respect to a midpoint between right and left halves of the subject's neck.

Apparatus and methods for monitoring electrical activity within the brain of a person (“brainwaves”) employing electrodes or other sensors placed proximate to portions of the body below the head to develop raw signals without physically touching the body and penetrating hair and clothing. Additionally, apparatus and methods for monitoring electrical activity within the brain of a person (“brainwaves”) employing non-contacting sensors placed proximate to portions of the head to develop raw signals. The raw signals are filtered to produce analysis signals including frequency components relevant to brain electrical activity while attenuating unrelated frequency components. The apparatus and methods can be used for biofeedback-based attention training, human performance training, gaming, biometrics, cognitive state detection, and relaxation training. Either wired or wireless signal connections are made to electronic circuitry, typically including a digital computer, for performing signal processing and analysis functions.

Each sensing electrodes is configured to be coupled eternally to a patient and to detect one or more ECG signals. The one or more processors are configured to receive at least one electrode-specific digital signal for each of the plurality of sensing electrodes, determine a noise component for each of the electrode-specific digital signals, analyze each of the noise components for each of the plurality of sensing electrodes, generate electrode matching information for each sensing electrode of the plurality of sensing electrodes based upon analysis of each of the noise components, determine one or more sensing electrode pairs based upon the electrode matching information, and monitor each of the one or more sensing electrode pairs for ECG activity of the patient.

The present technology relates to open respirator devices having sensors for measuring breath biometrics. For example, a respirator device (100) can include a mask component (102) that fits at least partially over a user's face and forms a gap (112) between a periphery of the mask component and the user's face, thereby forming a breathing chamber (108) between the mask portion and the user's face. A fan unit can provide air from the external environment to the breathing chamber for the user to inhale. In some embodiments, the air may be filtered before entering the breathing chamber and the fans may provide a positive pressure seal between across the gap. One or more sensors can be coupled to the mask component for measuring one or more metrics associated with the user's breath.
