  • Patent number: 9282601
    Abstract: The invention provides a method for improving operation lifetime of a capacitor module in an electronic circuit employing the capacitor module, comprising the steps of providing two or more capacitor modules of same configuration; and controlling alternately a respective one of the capacitor modules to operate in the electronic circuit for a first predetermined period of time. The invention also relates to a capacitor control circuit structure for use in a location of an electronic circuit previously occupied by an original capacitor module, and the capacitor control circuit structure exhibits the extended operation lifetime with respect to the original capacitor module. The invention also relates to the use of the capacitor control circuit structure in the electronic applications.

  • Patent number: 8893978
    Abstract: The present invention provides A surface identification system comprising: at least one identification code pattern comprising a plurality of recesses, through holes and/or projections formed on an code area of a first surface, the identification code pattern being made to correspond to the first surface or a second surface; and a code reading apparatus for reading the identification code pattern, the code reading apparatus being capable of irradiating light rays towards the code area, receiving reflected light rays reflected from the code area to read out the identification code pattern according to an amount of the reflected light rays from each of the plurality of recesses, through holes and/or projections, and indicating a correspondence between the identification code pattern and the first surface or the second surface. The invention also relates to a surface identification method, an object having an identification code pattern and a code reading apparatus for reading the object.

  • Publication number: 20140160692
    Abstract: The present invention provides a method for surface decoration of a three-dimensional object with ease. In one embodiment of the invention, a planar construction article that is foldable into the object is utilized. In another embodiment of the invention, multiple angle plates that are assembled into the object are utilized. The surface decoration process is carried out before the planar construction article is folded or before the angle panels are assembled together thereby to significantly simplify the decoration process of object faces in different orientations. The invention also provides a three-dimensional object obtained from the methods of the invention.
