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.

A system including a controllable device configured to provide a premises related service in an area of a premises. The system includes an electroencephalography (EEG) device configured to be positioned with respect to a head of a user and process signals detected in real-time. 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. A data is stored in the memory that associates each of a plurality of predetermined sets of signals from the brain detected via the EEG device with at least one control instruction. The execution of the instructions configures the processor to using the stored data, analyze the real-time detected signals to determine that the real-time detected signals correspond to one of the plurality of predetermined set of signals associated with the one control instruction and generate a control data signal based on the one control instruction.

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.

This invention relates to a device that is intended to synchronize electroencephalograms (EEGs), recorded by any digital equipment, to physical events (sensorial, visual or auditory stimuli) and behavioral events (motor response, vocal response), in order to allow EEG signal mediation for the purpose of visualizing Evoked Potentials or Event-Related Potentials, which are important research subjects in the neurosciences and clinical investigations into neurological and psychiatric pathologies. This invention allows any digital EEG device to be transformed into equipment that can record Evoked Potentials. This invention also provides a method for analog synchronization of EEGs with oscillating electric light-related events and motor behaviors.
