Abstract: An intelligent mouth opening rehabilitation device is provided, including: a body, an end of the body is provided with an upper bite pad and a lower bite pad; a pressure sensor, for detecting pressure data on the upper bite pad and/or the lower bite pad; a stepping motor, for driving the upper bite pad and/or the lower bite pad to swing longitudinally; and a processor, for controlling the stepping motor to operate or stop according to the pressure data and/or a preset training instruction, thereby driving the upper bite pad and/or the lower bite pad to swing longitudinally or to stop. Compared with traditional mouth opening rehabilitation devices, the intelligent mouth opening rehabilitation device controls automatically the upper bite pad and/or the lower bite pad to swing longitudinally, so that a mouth opening training is more accurate, and more controllable. Therefore, a rehabilitation effect is greatly improved.

Abstract: A video displaying method. The method includes applying a first frequency modulation in time domain on an original video thereby obtaining a first modulated video; applying a second frequency modulation in spatial domain on the first modulated video thereby obtaining a second modulated video including a first invisible-light image; and displaying the second modulating video with a corresponding frame rate. A time-domain frequency of the first invisible-light image is in a first range unrecognizable by a naked eye and recognizable by a video recorder. A spatial-domain frequency of the first invisible-light image is in a second range unrecognizable by the naked eye and recognizable by a video recorder.

The auxiliary viewing device realizes the temporal amplitude modulation of the composition basic sequence by a method of controlling the light intensity transfer rate from the display plane of the high speed display device to the human eye. The present invention can not only display different pictures required individually by a plurality of users with the same display device but can also solve the problems of pictures being insufficiently bright and the number of pictures that can be generated being very low; such problems being unable to be overcome by the time division multiplexing method.
