A headgear for magnetoencephalography includes a body defining a plurality of ports, where the body includes a first portion and a second portion; an adjustment mechanism coupled to the first portion and the second portion of the body and configured to adjust a separation between the first and second portion to facilitate fitting the headgear to a head of a user; and a plurality of optically pumped magnetometer (OPM) modules, where each of the OPM modules includes at least one vapor cell and is configured to be removably inserted into a one of the ports of the body, where each of the OPM modules is configured for coupling to a light source for receiving light.

The technology provides a multi-body earpiece suitable for use as an in-ear sensor system, which can be used for biometrics or a human-computer interface. The multi-body earpiece includes two body elements connected together by a flexure. These components provide at least 3 points of contact along different parts of the outer ear, in which the flexure is tethered to the two bodies and arranged to lock them in place during wear. In addition to having stability from moving while minimizing sound occlusion, this arrangement enables any electrodes for the on-board sensor(s) to remain in contact with the skin of the ear, and provide as many contact points in desired areas as the electronics dictate for the signals of interest.

A method receives continuous EEG data for a long duration of time from at least one electrode intracranially implanted in a subject. The method determines a current or predicted brain state from the EEG data using an artificial intelligence (AI) model.

An optically pumped magnetometer 1 includes: a cell 2; a pump laser 7 that emits pump light; one or more pump light mirrors that cause the pump light guided in a first direction; a probe laser 8 that emits probe light; a splitting unit 12 that splits the probe light into multiple light components; one or more probe light mirrors that cause each of the probe light components guided in a second direction, which is a direction perpendicular to the first direction; a detection unit that detects each of the probe light components perpendicular to the pump light inside the cell 2; and a derivation unit that derives a magnetic field corresponding to a region where each of the probe light components and the pump light are perpendicular to each other based on a detection result of the detection unit.

An electromagnet for a thermography system comprising a first elongated magnetic core spaced apart from a second elongated magnetic core; at least a first shorting bar connecting substantially at a first end of the first elongated magnetic core and a first end of the second elongated magnetic core; and at least a first excitation coil configured to conduct electrical current.

A non-invasive system and method are provided. Brain activity of a user is detected using a non-invasive brain interface when the user is exposed to an external stimulus. The user is determined to be negatively primed by the external stimulus based on the detected brain activity. An alert that the user is being negatively primed by the external stimulus is automatically provided. A tagged training session may be automatically provided to the user in response determining that the user has a negative mental state, thereby promoting a positive mental state of the user. A training session list containing the tagged training session may be automatically modified based on the determined mental state of the user.

Methods providing biofeedback generally comprising: detecting a brainwave segment present in the brainwaves; reproduction of the segment at a higher octave and rendering said higher frequency as a feedback signal to the person. The feedback signal can be rendered at a higher frequency by any number of octaves, and/or musical harmonies thereof. Feedback frequency and amplitude correspond to shifting frequency and amplitude in the underlying brain/heart activity. Feedback signal is preferably rendered within 100 msec from brainwave detection, and can be administered as treatment using any bandwidth within the electromagnetic spectrum including sub-audio, audio, ultrasonic, light, etc. The feedback signal can be delivered to the same or opposite side of the person relative to the hemisphere generating the signal. Said feedback signal can help balance brainwave activity, forge new neuro-circuits, increase interhemispheric communication, creativity and brain-efficiency thereby improving a full spectrum of nervous system activity from hyperarousal to deep sleep.
