Abstract: The present disclosure provides a magnetron sputtering apparatus and a cathode device of the magnetron sputtering apparatus. The cathode device includes a target material component, a magnetic circuit component, a transmission component and a driving component. The magnetic circuit component is configured to be arranged opposite to the target material component. The magnetic circuit component includes a plurality of magnetic circuit units capable of independently generating magnetic field. The transmission component is connected with each of the magnetic circuit units simultaneously. The driving component is configured to drive the magnetic circuit component to reciprocate between a first position and a second position in a preset direction by the transmission component.

Abstract: The present disclosure relates to methods and devices for connecting external equipment. The method may include in response to detecting that the external equipment is connected with a smart terminal, acquiring description information of the external equipment. The method may further include determining a keyboard type of the external equipment, based upon the acquired description information of the external equipment. The method may further include generating an equipment acknowledgement of, and establishing a connection to, the external equipment, based upon the determined keyboard type.

Abstract: The present disclosure relates to methods and devices for processing traffic data. A method may include acquiring a current location of a traveling vehicle. A method may further include, when the current location is not an identified traffic impediment location, monitoring an amount of variation of an impediment parameter when the vehicle is in the current location. A method may further include, when the amount of variation of the impediment parameter exceeds a predetermined range, sending the current location and the amount of variation of the impediment parameter to a traffic data server. Through a method, drivers may in real time learn accurate information about traffic impediments ahead, and may preemptively respond by lowering traveling speeds or bypassing the location.
