Abstract: In a voice-controlled navigation device and method, a voice command is received, and divided into voice segments Vi (i=1˜n) by comparing with one or more keywords. A voice segment Vi (i=1˜n) is obtained in sequence to be compared with tree nodes in a search tree of place names. A weight value of each tree node is computed according to a comparison, to select one or more tree nodes whose weight values are greater than a predetermined value. Routes formed by all the selected tree nodes are obtained to select a route whose total weight value is the greatest. A navigation to a destination is given by indicating the selected route on an electronic map according to place names represented by the tree nodes of the selected route.

Abstract: A system and a method detect solder paste printing. The system includes a detecting device for detecting solder paste when a scraping blade pushes the solder paste to spread over a template to obtain information associated with the rolling speed of the solder paste, and a state-indicating device for generating a printing-state indication based on the information associated with the rolling speed of the solder paste. The method includes detecting the solder paste during rolling to obtain the information associated with the rolling speed of the solder paste, and generating a printing-state indication based on said information associated with the rolling speed of the solder paste. By detecting the solder paste during rolling to obtain the printing state, it is possible to monitor the printing state in real time, discover an abnormal condition in time, and reduce costs to the maximum extent.

Abstract: A transparent panel is used to acquire a test sample from a machine to be tested; where the test sample includes at least one object placed on the transparent panel by the machine to be tested. A scanning device is used to scan the transparent panel to obtain image data and a computing device is used to determine the operation accuracy of the machine to be tested according to the image data from the scanning device. These devices may be used for machine performance testing and acquiring an image of the test sample.
