Abstract: An image display device may include a control device to estimate a user state based on a detected electroencephalogram signal of a user who is playing a game, and to control display of an image to the user for providing training for the game based on the user state.

Abstract: A signal processing system includes: one or more terminals via which a signal is outputted; and signal control means for sensing whether the connecting destination of each of the one or more terminals is in a state in which the connecting destination can treat an output signal sent via the terminal, and implementing at least one of variable control of a signal transmission path, which leads to the terminal serving as an output terminal, and variable control of a signal processing technique, which is applied to the signal transmission path, on the basis of the result of the sensing.

Abstract: A corrugation forming apparatus includes, as forming members, a rack tool assembled to a slide table and a pinion tool which rotates with rotation of a shaft. The apparatus also includes, as a displacement synchronization mechanism, a feed rack integrally assembled to the table and a feed pinion gear in meshing engagement with the feed rack. When a handle is rotated, its rotational force is transmitted to the feed rack via the feed pinion gear, so that the rack tool moves along the axial direction, and the pinion tool rotates in synchronism with the movement of the rack tool. This enables forming of successive recesses and projections on the thin metal plate, while reducing ductile cracks and warpage.
