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: An image sensing device and a control device of an illumination device thereof are provided. The control device includes a control circuit, an operation circuit, and multiple driving signal generators. The control circuit generates multiple control signals. The operation circuit performs a logical operation on the control signals and an image capturing signal to generate multiple operation results. The driving signal generator respectively provides multiple driving signals to the illumination device according to the operation results, and the driving signals respectively have multiple different output powers.

Abstract: A probe for providing micro liquid drops including a main rod, a limiting portion and a probe tip portion is disclosed. At least one guiding flow way and several storing recesses are disposed on the conical outer surface of the probe tip portion. Each storing recess has a volume that is larger than the volume of the guiding flow way. Also, under the gravity and capillarity effect, the output speed is controlled by the number, size and shape of the guiding flow ways and the storing recesses so that each probe structure is strong, the liquid storing capacity is high, its liquid output is stable, it is easier to manufacture the guiding flow ways, and it is easy to clean.

Abstract: A heat dissipating device includes a fin unit disposed on a supporting seat, and an anchoring frame disposed on the fin unit and engaging detachably the supporting seat for anchoring the fin unit between the supporting seat and the anchoring frame. A fan module includes a fan unit having a fan blade disposed in a fan housing that is mounted on the fin unit, a connecting seat mounted on the fan housing and formed with a through hole that is in fluid communication with an inlet hole in the fan housing, and an air guiding member mounted on the connecting seat and confining an air passage that is in fluid communication with the through hole in the connecting seat. The fan unit is operable so as to draw external air toward the fin unit via the air passage.
