Abstract: A magnetic multi-pole propulsion array system is applied to at least one external cathode and includes a plurality of magnetic multi-pole thrusters connected adjacent to each other. Each magnetic multi-pole thruster includes a propellant provider, a discharge chamber, an anode and a plurality of magnetic components. The propellant provider outputs propellant. The discharge chamber is connected with the propellant provider to accommodate the propellant. The anode is disposed inside the discharge chamber to generate an electric field. The plurality of magnetic components is respectively disposed on several sides of the discharge chamber. One of the several sides of the discharge chamber of the magnetic multi-pole thruster is applied for one side of a discharge chamber of another magnetic multi-pole thruster.

Abstract: A message transmission system, a receiving apparatus, a receiving method and a computer-readable recording medium thereof are provided. The message transmission system includes a transmitting apparatus, a receiving apparatus and a database. The transmitting apparatus transmits a broadcasting message, where the broadcasting message includes an identification code. The receiving apparatus forwards the identification code in response to receiving the broadcasting message. The database provides an intent content corresponding to the identification code without an application identification. The receiving apparatus presents a notification according to the intent content by an operation system (OS) without opening an application corresponding to the application identification in response to receiving the intent content. Accordingly, without installing an application for receiving a push message, the receiving apparatus still can receive the notification, and efficiency of push notification can be improved.
