Abstract: A brainwave control system and method operable through time differential event-related potential includes a brainwave capturing unit attached to a user's head, a brainwave signal processing apparatus and a display unit to display at least two sets of stimuli. The brainwave signal processing apparatus includes a signal processor connected to the brainwave capturing unit and a central processor. The signal processor converts brainwave signals generated by the user after having received a set of short time interval stimuli to digital signals. The central processor performs analysis and generates identification results and executes control commands accordingly. Thus user can rapidly and accurately execute his requirements of operation control so as to achieve non-contact operation control with improved usability and practicality.

Abstract: A door structure includes at least one hinge member having a first leaf fixedly mounted on one side plate of a mounting frame, and a second leaf pivotally engaged with the first leaf. A panel module includes at least two vertical side panels on one of which the second leaf is fixedly mounted. At least two horizontal side panels are each fixedly mounted between the two vertical side panels. At least two horizontal retaining members each include a first outer snapping portion mounted on one of the two horizontal side panels and a first inner snapping portion. At least two vertical retaining members each include a second outer snapping portion mounted on one of the two vertical side panels and a second inner snapping portion. At least two central panels are each fitted in the two first inner snapping portions, and are each fitted in the two second inner snapping portions. At least one reinforced beam is fixedly mounted between the two holding members and is rested between the two central panels.
