Abstract: A vehicle speed control method detects a speed of a vehicle by a speed sensor of the vehicle, and determines location information of the vehicle by a global positioning system when the vehicle is driving on a road. The method transmits the location information of the vehicle to a host via a network, and receives speed limit information of the road sent from the host. The method then determines whether the speed of the vehicle exceeds a speed limit range of the road. If the speed of the vehicle exceeds the speed limit range of the road, the controls an automatic gearbox of the vehicle to adjust the speed of the vehicle to fall within the speed limit range.

Abstract: A method stores multiple sets of consecutive images of a burner, determines a number of unburned-state images in each set of consecutive images, and determines a threshold number of the unburned-state images in each set of consecutive images for determining whether or not the burner works abnormally. When the burner is turned on, the method sends a first control signal to turn on a camera and receives a set of real-time consecutive images of the burner captured by the camera. The method determines whether or not a number of unburned-state images in the set of real-time consecutive images is less than the threshold number. If the number is equal to or more than the threshold number, the burner works abnormally and a security device connected to the burner is turned off to prevent gas from flowing to the burner.

Abstract: A parts assembly direction method stores sample images of parts and instructions for assembly of the parts in a storage device of an assembly table. When the assembly table receives the parts, a camera captures a real-time image of the assembly table, and the method determines if the real-time image of the assembly table contains images of the parts. If the real-time image of the assembly table contains images of the parts, the method determines whether the parts are qualified by comparing the images of the parts with the sample images of the parts. If the parts are unqualified, the method displays prompt information on a screen of the assembly table to alert users that the parts are unqualified. Otherwise, if the parts are qualified, the method displays the real-time image of the assembly table and the instructions for assembly of the parts on the screen.
