    Abstract: A super-conductive tube used for a discharge device is formed integrally by a super-conductive material. The super-conductive tube is a hollow tube formed by a front end surface, a rear end surface, an inner tube wall and an outer tube wall. An interior of the super-conductive tube is formed with a hollow space and an interior of the hollow space is in a vacuum state. The inner tube wall and the outer tube wall are formed by extending the front end surface toward the rear end surface and an end of the outer tube wall is extended with a guide portion toward the discharge device. Accordingly, when the super-conductive tube is applied to a discharge device, electrical energy will be generated by the super-conductive tube through a magnetic field that results from an operation of electric current, after the discharge device has released electric energy.

  • Fan noise canceling system
    Patent number: 8259955
    Abstract: In a fan noise canceling system, a feedforward signal generated when a fan speed change occurs and a feedback signal read by a sensor are sent to a signal amplifying unit for signal amplification, and the amplified signals are then sent to a signal converting unit for converting into a digital signal. A hybrid controller receives and corrects the digital signals sent thereto, and conducts rapid convergence algorithm to derive a reverse digital signal. The reverse digital signal is sent back to the signal converting unit for converting into a reverse analog signal, which is then sent to the signal amplifying unit for power amplification and generating a control signal to drive a loudspeaker to produce a reverse acoustic wave, which cancels out wave of fan noise to effectively reduce fan noise without adversely affecting the heat dissipation effect of the fan.
