  • SELECTING OPTIMAL IMAGE FROM MOBILE DEVICE CAPTURES
    Publication number: 20180139377
    Abstract: Device logic in a mobile device configures a processor to capture a series of images, such as a video, using a consumer-grade camera, and to analyze the images to determine the best-focused image, of the series of images, that captures a region of interest. The images may be of a textured surface, such as facial skin of a mobile device user. The processor sets a focal length of the camera to a fixed position for collecting the images. The processor may guide the user to position the mobile device for capturing the images, using audible cues. For each image, the processor crops the image to the region of interest, extracts luminance information, and determines one or more energy levels of the luminance via a Laplacian pyramid. The energy levels may be filtered, and then are compared to energy levels of the other images to determine the best-focused image.

  • METHOD OF MAKING AN END PIECE OF AN EYEGLASS FRAME
    Publication number: 20180071823
    Abstract: A method of making an end piece of an eyeglass frame includes the steps of: closing first and second mold cores to define therebetween a mold cavity having a shape corresponding to that of the end piece, the mold cavity having an injection hole communicating with an external environment; injecting metal clay through the injection hole into the mold cavity at a high pressure to form an end piece blank; separating the first and second mold cores to expose the mold cavity and then ejecting the end piece blank from the mold cavity by a blank ejector module; and subjecting the end piece blank to a sintering process.

  • Eyewear supporting one or more electrical components
    Patent number: 9690121
    Abstract: Techniques for providing eyewear with electrical components are disclosed. The electrical components can provide electrical technology to eyewear without having to substantially compromise aesthetic design principles of the eyewear. The electrical components can be partially or completely internal to eyewear. The electrical components can also be attached to the eyewear as an after-market enhancement. The electrical components can operate independently or together with other electrical components provided elsewhere. Apparatus for presenting after-market electrical components are also disclosed.

  • Fluid lens assembly
    Patent number: 9690015
    Abstract: A fluid lens assembly includes: a first lens having a first lens-viewing center; a second lens having a rear concave portion that defines a rear recess and a second lens-viewing center which is aligned with the first lens-viewing center along a viewing axis; and a membrane that is stacked between the first lens and the second lens, that covers the rear recess, that has a membrane-view center, and that cooperates with the first lens to define an accommodating space therebetween for receiving a fluid layer. The membrane wraps around a periphery of the rear recess and is deformed into the rear recess such that the membrane-viewing center is kept aligned with the first lens-viewing center along the viewing axis during inflation of the membrane.
