  • Patent number: 10242364
    Abstract: A user can be authenticated to a mobile computing device using an authentication process that recognizes the user and verifies that an actual human being is attempting to be authenticated, in order to minimize the ability of another person to spoof the authentication process. A model of a user can be generated and stored in the cloud, enabling that model to be synchronized across various devices. A user accessing one of these devices can have infrared image information captured, which can be used with a facial recognition process, to recognize the user, and with a human verification process, to verify that the facial information corresponds to a human user. Various approaches such as visual analysis and thermal imaging can be used to verify that the human user being recognized is interactive with the device.

  • Patent number: 10240994
    Abstract: A sensor includes two coaxial RF shielding members arranged to create a coaxial RF shielding structure that is electrically open and is formed from partially enclosed cylindrical shells. The RF shielding members are spaced from one another. The sensor also includes one or multiple electrically conductive coaxial coils between the coaxial RF shielding members. This configuration creates an LC circuit without requiring a separate capacitor electrically connected to the inductor. The RF shielding structure minimizes the surrounding tissue effects (e.g., parasitic capacitance), which improves the overall accuracy of the sensor. The LC circuit also can be remotely interrogated by external reader.

  • Patent number: 10244323
    Abstract: Disclosed is a vibration sound-producing apparatus. A sound output aperture is provided on a sidewall perpendicular to a thickness direction. A diaphragm is parallel to the plane on which the sound output aperture is located. A flat sound coil is perpendicular to the diaphragm. Two magnets parallel to the sound coil are arranged at either side of the sound coil. The vibrating direction of the sound coil avoids the thickness direction. The vibrating direction of an integral structure of the magnets and a magnetic conductor part also avoids the thickness direction. This facilitates a thickness-reduced design for a product, increases the space for vibration, and enhances product performance, meanwhile, the design of the two magnets effectively increases the strength of the magnetic field within the product, this further improving product performance. The vibration sound-producing apparatus of the present invention has the advantages of a great thickness-reduced design and great performance.
