A system assists users in time and frequency analysis of magnetoencephalography (MEG) signals. In one aspect, a system includes an analysis module, a configuration module and a user interface. The analysis module performs a time and frequency analysis of the MEG signal, for example a short time Fourier transform (STFT) or a continuous wavelet transform (CWT) analysis. The analysis is parameterized by a parameter set that affects the time and frequency resolution of the analysis, for example window size and overlap size for STFT or center frequency and decay parameter for CWT. The configuration module automatically determines or assists the user to determine correct values for the parameter set.

The gradiometers of the present invention are developed by applying GSR sensors to have the detectability of magnetic field same to that of SQUID without a cryogenic temperature retainer. Plural GSR elements are fitted on two parallel convex line guides of the gradiometer board using two parallel concave line guides of the GSR element board to keep the parallel among wires direction of GSR elements perfectly and to cancel the outside magnetic field noise without a magnetic shield room.

A medical device for the measurement of brain temperature data through the Abreu brain thermal tunnel (ABTT) is described. Brain temperature measurement is the key and universal indicator of both disease and health equally, and is the only vital sign that cannot be artificially changed by emotional states. Currently, brain temperature is difficult to measure. However, the present disclosure describes a device that readily locates the Abreu brain thermal tunnel, and is configured to provide a non-contact temperature reading of the brain. Embodiments of the disclosed device enable an individual to measure their own temperature and enable medical professionals to measure the temperature of others.
