The disclosure relates to an extraction device for extracting soluble favors from raw materials that are distributed within liquid. The extraction device includes a first container, a second container, a valve, and an air suction device. The second container is configured for storing the mixture of the raw materials and the liquid. The valve is connected to the second container and the first container. The air suction device is connected to the first container and configured to decrease the internal pressure of the first container to a predetermined value. When the internal pressure of the first container reaches the predetermined value, the valve is activated to connect the first container to the second container. The disclosure also relates to an extracting method for using the extraction device.

Extraction device and extracting method

An optical touch apparatus including two touch panels, two optical sensing modules, and a rail device is provided. Each touch panel has two lateral sides separated from each other and a touch zone located between the two lateral sides. Each optical sensing module is disposed or near one lateral side of one of the touch panels. The rail device is coupled to the two touch panels, such that two touch panels can slide in parallel along a predetermined direction and can be selectively operated in one of a first touching mode and a second touching mode, and the optical touch apparatus can flexibly change its size of touch zone.
