Abstract: The present disclosure discloses a contact angle measuring device, including a light source, a container, a photodetector, a bubble generating unit, and a processing unit. The container includes a first and a second side walls that are opposite. The first side wall is made of a light-transmitting material, the container is filled with a liquid with light transmission inside. The monochromatic light emitted by the light source passes through the first side wall and enters an interface between the first side wall and the liquid. The bubble generating unit is configured for generating a bubble that is in contact with an inner surface of the first side wall. The photodetector is configured for detecting light intensity distribution of the monochromatic light through the liquid.

Abstract: An information processing device, a data processing method thereof, an input device, and an input controlling method are described. The information processing device is capable of responding to an input operation of an input device, and the input device includes an input component located at end portion thereof. The information processing device includes a sensing module capable of sensing a position of the input component with respect to the sensing module when the distance between the input component and the sensing module satisfies a first predetermined condition, a first controlling module judging whether the information processing device satisfies a second predetermined condition when the distance satisfies the first predetermined condition, responds to an input operation corresponding to the position of the input component with respect to the sensing module when the information processing device satisfies the second predetermined condition, or otherwise, does not respond thereto.
