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 storage interface cable for advanced technology attachment (ATA) applications is provided. In a preferred embodiment, the storage interface cable comprises: a bus line conveying signals; a host connector at a middle part of the bus line for being attached to a host; a master connector at an end of the bus line for being attached to a master device; and a slave connector at another end of the bus line for being attached to a slave device. Because the host connector is at the middle part of the bus line, a length of the bus line between the host connector and the slave connector is not dependent on a length of the bus line between the host connector and the master connector. Therefore, the storage interface cable provides a configuration for a host and devices avoiding quality debasement of signals or data corruption due to excessive length of the bus line.
