Abstract: A system for storing wafer is provided. The system includes a wafer box, an installing member, a detection tube, a control unit, and a detection unit. The wafer box includes an outlet connector and an inlet connector extending a wall of the wafer box. The installing member covers the wafer box to form a sealed receiving room. Two ends of the detection tube are coupled to the outlet connector and the inlet connector. The control unit are configured to output a first control signal to the detection unit. The detection unit includes a first sensor arranged in the detection tube. The first sensor is configured to detect a property of gas to obtain data of an environment where the wafer is stored upon the first control signal. A related system for monitoring pollution of wafer is also provided.

Abstract: A mobile electronic device stores a standard voice command and a voice command identification standard. When an incoming call is regarded as a missed call and a voice command is detected, the mobile electronic device compares characteristics of the voice command with characteristics of the standard voice command, so as to determine if the voice command satisfies the voice command identification standard. The mobile electronic device further activates a ringing circuit to play a predetermined ring tone in response that the voice command satisfies the voice command identification standard, so as to help a user locate the mobile electronic device even if the mobile electronic device is in a silent mode.

Abstract: A voice recognition system and method of a mobile communication device. The mobile communication device has a storage device which stores voice templates and characteristics of each of the voice templates. The method recognizes voice data form a sound input, calculates a similarity ratio between characteristics of the sound input and the characteristics of each of the voice templates, and sorts the voice templates according to the similarity ratio in a list of text symbols representing the voice templates. The list of text symbols can be selected as a proper text input by a user.
