    Abstract: An electric pot, which comprises: at least one light source, configured to emit light to liquid in the electric pot, wherein the light forms a first light pattern on a surface of the liquid; an image sensor, configured to detect the first light pattern; and a processor, configured to determine a liquid level of the liquid based on the first light pattern. Further, the processor can determine a solid height of the solid in the liquid based on a second light pattern. Via such electric pot, the liquid level or the solid height can be calculated in an optical manner, thus the user may feel more convenience while using the electric pot.

    Abstract: There is provided an encoding and decoding method and an information recognition device using the same. A code block includes a center coding region and a peripheral coding region arranged around the center coding region. The encoding and decoding method uses the feature of at least one microdot included in the center coding region as codes. The encoding and decoding method uses the feature of at least one microdot included in the peripheral coding region as codes. The encoding and decoding method uses the relative feature between the center coding region and the peripheral coding region as codes. The information recognition device compares the read feature with pre-stored features to decode information such as position codes, object codes, parameter codes and control codes.

    Abstract: A temperature detecting device is cooperated with an air conditioner. The temperature detecting device includes a temperature detector and a visual indicator. The temperature detector is utilized to generate a temperature distribution result about a specific area. The visual indicator is electrically connected to the temperature detector and utilized to provide a visual mark indicating position information according to the temperature distribution result. The conditioner includes an air supply module, a wind adjustment module and a detection camera. The wind adjustment module is adapted to adjust wind's direction from the air supply module. The detection camera is electrically connected with the wind adjustment module and adapted to detect the visual mark for controlling the wind adjustment module.

    Abstract: A locating method applied to an optical touch device is disclosed. The optical touch device includes at least one image detecting component for detecting an imaging position of an object and generating a touch position of the object on a plane according to the imaging position. The at least one image detecting component includes a plurality of pixels. The locating method includes dividing the pixels into a first group and a second group along a first direction, analyzing dimension ratios of a darkness point respectively relative to the first group and the second group when the darkness point formed by the object is simultaneously detected by the first group and the second group, and calculating the imaging position of the darkness point inside the image detecting component according to the dimension ratios.
