Abstract: A wavelength conversion device disclosed adopts a drive gear and driven gear as a main transmission structure, and disposes optical fiber plugs at a center of the driven gear. When a central shaft of the driven gear is unmovable, the rotation of the drive gear will drive the driven gear to rotate, and the rotation of driven gear will drive the optical fiber insertion rod to move up and down, thereby completing an insertion-extraction operation of the optical fiber insertion rod. When the central shaft of the driven gear is movable, i.e., when the optical fiber plugging rod is completely above the baseplate, the driven gear is locked with the optical fiber plug and thus they both cannot be rotated about their own axis, the driven gear will drive the fiber displacement plate to rotate along the drive gear under the action of the drive gear, thereby realizing the rotational translation of the optical fiber plugs, and reaching the switching wavelengths of laser at the optical fiber output interface.

Abstract: Recognizing mental states from physiological signal is a concern not only for medical diagnostics, but also for cognitive science, behavioral studies as well as brain machine interfaces. Embodiments of the present disclosure utilize respiration signals to decipher mental states wherein non-linear baseline drifts in signal is implemented to extract the respiratory features in most effective way. Presence of class imbalance, is effectively rectified using Synthetic Minority Oversampling Technique (SMOTE) to resolve class imbalance problem, which not only increased the classification accuracy, but also reduced classifier bias towards the majority class, which in turn exceedingly enhanced the classifier sensitivity.
