摘要： In a method for processing shareware using a host computer, a plurality of installation modes and authorization modes are sent to a client computer if the client computer requests the host computer for a shareware installation file of the shareware in the host computer. A selected installation mode and a selected authorization mode of the client computer are determined by decrypting encrypted data from the client computer using a preset decryption formula. The method further monitors the client computer according to the selected authorization mode to determining whether the client computer is allowed to run the shareware. When the client computer runs the shareware, the method records usage status of all functions of the shareware in the client computer and receiving error reports from the client computer. The method further sends solutions to the client computer in response to the error reports.

摘要： A computing device reads pixels of an image of a product along an x-direction and a y-direction of the image. In response to reading two neighboring pixels having different color values, the device regards one pixel having a predetermined color value from the two neighboring pixels as a profile point of the image, to generate one or more point-clouds consisting of all profile points of the image. Furthermore, the device reads one or more theoretical profile curves of the product from the storage device, aligns the one or more point-clouds and the one or more theoretical profile curves, and determines a minimum distance from each profile point in the one or more point-clouds to the one or more adjusted theoretical profile curves. A profile tolerance of the product is then determined according to a maximum value and a minimum value of the minimum distances.
