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 display apparatus includes a backlight module with backlight zones, a panel over the backlight module, and a circuit configured to generate compensated pixel data for the panel based on image data and an arrangement of the zones of the backlight module, in which the image data has image areas respectively corresponding to the backlight zones. For a first image area being a low-luminance image area and a luminance intensity of a first zone of the zones corresponding to the first image area being less than a luminance intensity of a second zone corresponding to a second image area neighboring the first image area, the circuit performs first pixel compensation for high-luminance pixels in the second image area and second pixel compensation on low-luminance pixels in the second image area, in which the second pixel compensation is greater than the first pixel compensation.

Abstract: The present invention provides a method for protecting an input/output port of a computer. The method includes the steps of: searching for the entry representing the input/output port in the system's registry editor (REGEDIT) of the computer according to a corresponding global unique identifier of the input/output port; obtaining a component identifier of the input/output port from the entry; searching for the physical input/output port having the obtained component identifier in the hardware library of the computer; defining a parameter for controlling the authorization of accessing the physical input/output port, the parameter having an ENABLE value and a DISABLE value corresponding to an accessible status and an inaccessible status of the physical input/output port respectively; and setting a password for controlling the authorization of changing the value of the parameter.

Abstract: A printed circuit board includes improved via for improving signal integrity. The printed circuit board includes a first layer, a second layer, a third layer and a via. The via includes a drill hole, a first pad and a second pad. The first pad is defined in the first layer, and the second pad is defined in the second layer. The drill hole is transversely defined through the first layer and the second layer. A void is defined in the third layer corresponding to the second pad. The PCB attenuates signal reflection when the signal is transmitted through the via improving signal integrity.
