With explosive penetration of portable electronic devices (PEDs) recent focus into consumer EEG devices has been to bring advantages including localized wireless interfacing, portability, and a low-cost high-performance electronics platform to host the processing algorithms to bear. However, most development continues to focus on brain-controlled video games which are nearly identical to those created for earlier, more stationary consumer EEG devices and personal EEG is treated as of a novelty or toy. According to embodiments of the invention the inventors have established new technologies and solutions that address these limitations within the prior art and provide benefits including, but not limited to, global acquisition and storage of acquired EEG data and processed EEG data, development interfaces for expansion and re-analysis of acquired EEG data, integration to other non-EEG derived user data, and long-term user wearability.

The invention provided herein relates to a wearable medical device and methods of use thereof for monitoring brain signals by electroencephalography technology in critically ill subjects suspected of having abnormal brain wave patterns including but not limited to electrographic seizures, spike and waves, periodic discharges and rhythmic delta activity.

A system including an electroencephalography (EEG) device configured to be positioned on a head of a user and process detected EEG signals. The system also includes a processor in communication with the EEG device, a memory accessible by the processor and instructions stored in the memory for execution by the processor to generate, based on a control instruction, a control data signal, for control of an operation of a controllable device configured to provide a premises related service in an area of a premises. In the training phase, execution of the instructions configures the processor to determine whether or not that the control operation of the control data signal is consistent with the detected EEG signals based on a trusted input from the user, and upon determination that the control operation is consistent with the detected EEG signals, store, in the memory, recognition data characterizing the detected EEG signals as a predetermined set of signals in association with the control instruction.

The disclosure relates to the field of electronic medical technology, and provides an EEG device, a system, a computer device and a storage medium. The EEG equipment includes: a stimulation unit for generating stimulation signals; an acquisition unit for collecting physiological electrical signals of the human brain; wherein the acquisition unit for collecting physiological electrical signals of the human brain includes: When the stimulation signal is mentioned above, the collection unit collects the physiological electrical signal of the human brain according to the first collection parameter; during the process of applying the stimulation signal to the human body by the stimulation unit, the collection unit collects the physiological electrical signal of the human brain according to the second collection parameter; wherein, The first collection parameter is different from the second collection parameter. With the technical solution of the present disclosure, the acquisition unit uses different acquisition parameters to acquire brain physiological electrical signals during the stimulation process and the non-stimulation process, so as to reduce the influence of aliasing noise and signal saturation on the acquisition signal during the stimulation process, and then Effective EEG data can be collected.

A system including an electroencephalography (EEG) device configured to be positioned on a head of a user. The system also includes a processor in communication with the EEG device, a memory accessible by the processor and instructions stored in the memory for execution by the processor to, in configuration phase, for each respective location among a plurality of locations at a respective time among a plurality of times, obtain an identification (ID) associated with the respective premises at the respective time, determine a control instruction associated with the EEG signals detected from among a plurality of control instructions; store the determined control instruction in association with the obtained premises ID, as a user preference data relative to the respective location; and at a later time, during an operational phase at the respective location, utilize the stored user preference data to communicate a control data signal corresponding to the determined control instruction to a controllable device at the respective premises.

The present invention provides a video content evaluation method and a video content evaluation system, the method comprising: in the first test stage, the receiving eye movement equipment collects the eye movement signals in the process of each subject watching the video sequence, and obtains the first eye movement data, and receiving the EEG signal collected by the EEG equipment to obtain the first EEG data; calculating the first eye movement index data based on the first eye movement data; calculating the first emotional index corresponding to each target video in the first test stage based on the first EEG data value; in the second test phase, the receiving EEG device collects the EEG signal to obtain the second EEG data; calculates the second emotional index data according to the second EEG data, and calculates the second emotional index value from the second emotional index data; A comprehensive evaluation value of the target video is calculated based on the first eye movement index value, the first emotional index value, and the second emotional index value, and a first evaluation result is obtained according to the comprehensive evaluation value. Through the above steps, in order to achieve objective, direct and accurate evaluation results obtained.
