Abstract: A method of wireless signal transmission management includes transmitting a plurality of data packets to tethering equipment from user equipment to tethering equipment, determining a size of each of the plurality of data packets by the tethering equipment, designating data packets of the plurality of data packets having a specific range of sizes as control signal packets by the tethering equipment, and prioritizing in transmitting the control signal packets to a cellular network by the tethering equipment.

Abstract: A method for controlling a device for automatically adjusting an airway opening body position is provided. The device includes a horizontal base plate, a head support block, a back support plate, a neck support apparatus, a head cover assembly, and a programmable logic controller (PLC). The neck support apparatus is positioned between the head support block and the back support plate. The PLC is configured to controls a stroke of an electric cylinder according to the following equations: ?=1.235?+?, and ?=KX+B+C, where ? is a body position angle, the body position angle is an angle between a positive projection line of a connecting line from a mandibular angle to an external acoustic meatus on a symmetrical surface of a human body and the back support plate, and ? is a preset value ranging from 90° to 100°.

Abstract: A remote video-on-demand digital monitoring system principally includes an image capture module, a server relay module and a video-on-demand module. The image data of said image capture module are stored in the server relay module through a telecommunication network. Through the telecommunication network, customers can browse the monitored web pages of the video-on-demand module via a browser, and view or store the monitored image data at a desired time segment according to a video-on-demand or movies-on-demand mode.

Abstract: An innovative method of automatic vehicle licence plate recognition is described, the vehicle licence plate recognition procedure is carried out respectively with reference to three component color red(R), green(G), and blue(B) grey level pixel maps, and then the results are reorganized. Sine the synthesized three component color R, G, B grey level pixel map is obtained by mixing R, G, B color component according to a definite proportion (for example dividing the sum of three component by 3), hence among the three component color grey level pixel maps, there must be at least one (R, or G, or B) whose contrast is better than that of the synthesized one. This most confidential one is picked out as the final result of the licence plate recognition.
