Patents by Inventor Guang-Chyeng Fang

Guang-Chyeng Fang has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 6938487
    Abstract: An inertia device is constructed by both suspension structure and micro-electroplating structure. The suspension structure may be manufactured by surface micromachining technique of sacrificial layer process or bulk micromachining technique incorporating with thin film process. One side of the suspension structure is arranged firmly to a supporting piece, so that another side of the suspension structure is in a suspension state. The suspension side of the suspension structure is made as micro-electroplating structure through the micro-electroplating process and functions as inertia mass for an inertia sensor. The size of the micro-electroplating structure may be changed through the micro-electroplating process, such that the inertia sensor may be adapted for sensing in different levels.

  • Patent number: 6901799
    Abstract: The invention is to provide a vibratory double-axially sensing micro-gyroscope, which includes a base, on center of which a supporting hub is arranged, and plural suspending arms are extended outwardly with equal altitude and in radial direction from the supporting hub and, at the outside end of the suspending arm, a platform is formed, and a capacitance sensing electrode or a static-electricity driving electrode is plated respectively at each side of the platform top, below which a static-electricity driving electrode or a capacitance sensing electrode is arranged; take a preferred embodiment of the present invention for example, if the capacitance sensing electrode is arranged at top of the platform and the static-electricity driving electrode is arranged below the platform, then the suspending arm and the platform will vibrate vertically by the attraction of the static-electricity when applying driving voltage, and the vibratory phase difference between two adjacent suspending arms and the platform is 180

    Abstract: A performance-adjusting device for inertia device is constructed by both suspension structure and micro-electroplating structure. The suspension structure may be manufactured by surface micromachining technique of sacrificial layer process or bulk micromachining technique incorporating with thin film process. One side of the suspension structure is arranged firmly to a supporting piece, such that another side of the suspension structure is shown as a suspension state. The suspension side of the suspension structure is made as micro-electroplating structure through the micro-electroplating process and is functioned as inertia mass for an inertia sensor. The size of the micro-electroplating structure may be changed through the micro-electroplating process, such that the inertia sensor may be adapted for sensing in different levels.
