  • Publication number: 20200243421
    Abstract: A water-cooling thermal dissipating method controls at least one of a fan, a pump, and a throttle valve to cool a heat generating element inside an electronic device through a cooling liquid. The method includes steps of: (a) performing a self-condition inspection, (b) detecting whether a working temperature of the cooling liquid is greater than a first predetermined temperature, and detecting whether a working temperature of the heat generating element is greater than a second predetermined temperature, (c) outputting a first warning signal if the working temperature of the cooling liquid is greater than the first predetermined temperature and a liquid level of the cooling liquid is not lower than a threshold liquid level, and outputting a second warning signal if the working temperature of the heat generating element is greater than the second predetermined temperature, and (d) displaying the first warning signal and the second warning signal.

  • Publication number: 20190286784
    Abstract: A method (of generating a layout diagram of a wire routing arrangement in a multi-patterning context having multiple masks, the layout diagram being stored on a non-transitory computer-readable medium) includes: placing, relative to a given one of the masks, a given cut pattern at a first candidate location over a corresponding portion of a given conductive pattern in a metallization layer; determining whether the first candidate location results in at least one of a non-circular group or a cyclic group which violates a design rule; and temporarily preventing, if there is a violation, placement of the given cut pattern in the metallization layer at the first candidate location until a correction is made which avoids violating the design rule.

  • Patent number: 7957250
    Abstract: A micro optical head is provided, which provides sub-wavelength focusing spot and very long depth of focus. The optical head includes a transparent substrate, an opaque film, and at least one sub-wavelength annular channel. After coherent light transmits the transparent substrate supporting the optical head and passes through the appropriately designed sub-wavelength annular channel, the transmitted light can overcome the diffraction limit, and the transmission energy is improved efficiently. The transmitted light converges after a certain distance behind the optical head and forms a sub-wavelength-scale beam that maintains a very long distance without divergence.
