Patent number: 9772498Abstract: The present invention is a magnified screen cover and protector for electronic devices. The invention comprises a magnified surface layer with a top protective layer and a bottom adhesive layer. The invention magnifies the screen of an electronic device with diopter and/or magnification power ranges so that the user may comfortably use the electronic device without the aid of wearing prescription eyewear, contact lenses, reading glasses or other visual aids. The touch screen sensitivity and functionality of the electronic device is unaffected by the magnified screen cover protector, so usability of the electronic devices touch and sensitivity functions are not compromised. The present inventions additional benefit is protecting the glass and/or plastic surface of an electronic devices main viewing screen from scarring, shattering, debris and breakage.Type: GrantFiled: June 13, 2014Date of Patent: September 26, 2017Inventor: Dana Conrad Kowasic

Patent number: 9681522Abstract: An adaptive light system including a color matching engine, a controller, and a plurality of light sources each configured to emit a source light. The color matching engine determines a dominant wavelength of a selected color, and a combination of the light sources that the controller may operate to emit a combined wavelength that approximately matches the dominant wavelength of the selected color. A color capture device transmits a source color signal designating the selected color. A method of adapting light comprises receiving a selected color, converting a value representing a dominant wavelength of the selected color, determining a combination of and percentages of colors emitted by the plurality of light sources that may be combined to form an adapted light that matches the selected color, and operating the light sources along with a white light to emit the adapted light.Type: GrantFiled: February 25, 2013Date of Patent: June 13, 2017Assignee: Lighting Science Group CorporationInventors: Fredric S. Maxik, Robert R. Soler, David E. Bartine, Matthew Regan, Eliza Katar Grove, Valerie A. Bastien, Mark Andrew Oostdyk

Patent number: 9612694Abstract: A method for manufacturing a touch panel includes forming a light-shielding conductive patterned layer on a transparent substrate, which includes a light-shielding wire, a first contact pad and a first bridging electrode. An insulating layer is formed on the first bridging electrode, the first contact pad and the transparent substrate. First and second openings are formed in the insulating layer to respectively expose a portion of the first bridging electrode and a portion of the first contact pad. A transparent conductive patterned layer is formed, which includes first sensing electrodes, second sensing electrodes, a second bridging electrode and a second contact pad. Each first sensing electrode is connected to the first bridging electrode through the first opening. The second sensing electrodes are connected to each other through the second bridging electrode. The second contact pad is connected to the first contact pad through the second opening.Type: GrantFiled: February 7, 2014Date of Patent: April 4, 2017Assignee: AU OPTRONICS CORPORATIONInventor: Teng-Fu Tung

Patent number: 9612367Abstract: A method of producing an optical device, which includes a center region where a light absorbing part is substantially absent, a peripheral region, and an intermediate region between the center and peripheral regions, where the thickness of the light absorbing part gradually increases in a direction from the center region to the peripheral region, includes applying a resin material that absorbs light onto a transparent base material. A forming mold including a convex and a concave corresponding to the shape of the light absorbing part is pressed against the applied resin material. The light absorbing part is formed by curing the resin material through exposure to ultraviolet radiation with the forming mold being pressed against the resin material. A surface of the convex that faces the resin material when the forming mold is pressed against the resin material corresponds to the center region of the optical device and is flat.Type: GrantFiled: June 12, 2015Date of Patent: April 4, 2017Assignee: Asahi Glass Company, LimitedInventor: Takuji Nomura
