  • Patent number: 9506777
    Abstract: A micro-electromechanical apparatus having a signal attenuation-proof function, and a manufacturing method and a signal attenuation-proof method thereof are disclosed. The micro-electromechanical apparatus includes a substrate, an insulation layer, and a sensing unit. The substrate has a doped region in which a majority of conductive carriers have the same polarity as an electronic signal. The insulation layer is located on the substrate, and the sensing unit is located above the insulation layer and forms the electronic signal when sensing a force.

  • Publication number: 20150278248
    Abstract: The present invention provides a business card image based personal information management service system. The present invention creates a novel personal information management system based on recognition and management of business cards. The present invention allows a user to establish a new personal information file by inputting a business card using a portable device. With a human face image database that includes facial images of a limited number of persons belonging to a defined scope, automatic facial recognition services are provided by the invented system. Facial recognition is automatically processed upon receipt of an input image by user through the portable device.

  • Patent number: 9086276
    Abstract: The present invention relates to a liquid multilayer capacitive micro inclinometer, comprising at least two pairs of differential electrodes, each pair positioned in a same plane; at least one common electrode with a portion positioned in the plane of each pair of differential electrodes. The differential electrodes and the common electrode are provided in a sealed chamber, in which an immersing liquid is filled. The shape of the differential electrodes forms a sector of a circular plane. The inclinometer may further integrate a reading circuit. The present invention also discloses preparation method for the invented inclinometer.

  • Patent number: 8980669
    Abstract: The present invention discloses an adhesive-free method for preparation of micro electro-mechanical structure, comprising forming a micro electro-mechanical structure on a first substrate, forming an enclosing space for immersing liquid on the first or second substrate, and applying pressure to fix the first and second substrate. Before applying the pressure, the assembly including the two substrates is flipped, to make the contact surface immersed by the immersing liquid.
