Abstract: The invention provides a material surface treatment equipment, which is applied to a material substrate. The material surface treatment equipment includes a surface treatment device and at least one waveguide device. The surface treatment device is used to carry the material substrate to perform a surface treatment process. Each waveguide device is used for introducing electromagnetic waves to the material substrate to assist in performing the surface treatment process. Through the introduction of electromagnetic waves, the surface treatment process of the material substrate is easy to perform and can achieve the strengthening effect.

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°.
