Abstract: A method and system for neuro-feedback training are disclosed. According to certain embodiments, the method may include receiving, by a processor via a communication network, a brainwave signal measured by at least one sensor attached to a user. The method may also include determining, by the processor, a frequency distribution of the brainwave signal. The method may also include determining, by the processor, a reward in a video game when at least one first value indicative of an amount of the brainwave signal within a first frequency band meets a first criterion. The method may further include providing, to the user, a first feedback signal indicative of the reward.

Abstract: Disclosed are a teaching method and a teaching device for improving attention and a computer readable storage medium. The method includes the following operations: obtaining brainwave data of a user collected by an electroencephalograph (EEG) acquisition device, and calculating an attention value according to the brainwave data; switching to a training mode if the attention value is less than a first preset threshold; and obtaining an EEG feature of the user during training, and outputting and displaying an animation effect corresponding to the EEG feature to adjust the user's attention.

Abstract: Apparatus and methods for material separation consisting of a cyclone aerator which can enhance contact between contaminated water and air, or a oxidant gas, and can enhance the contact and attachment between particulates contained in the suspension and bubbles formed in the cyclone aerator. One embodiment comprises a plurality of plates positioned in a spaced relationship to one another within a jacketed tube. The plates are arranged in a distinct, non-radial orientation extending partially towards the center of the jacketing tube to define a cylindrical chamber within a center of the plates and an annular cylindrical chamber between the plates and the jacketing tube. A suspension is introduced into the cylindrical chamber tangentially through a feed line proximate or integral with a jacketing tube top of said jacketing tube to develop a swirling flow pattern of the suspension within the cylindrical chamber.
