Patent number: 11710759Abstract: One or more systems and/or methods are disclosed for building a relief print generator with no bezel. An electrode layer having more than one electrode can be used in an electrode-based, electro-luminescence component of the relief print generator. The respective electrodes may be connected to power sources with different voltage phases. An electrical circuit can be created between a biometric object and more than one electrode in the electrode layer when the biometric object contacts a surface of the generator. The electro-luminescent component can be activated by electrical charge and emit light indicative of a relief print of the biometric object. A contact electrode outside the electrode layer may not be used, which may allow for the removal of a bezel from an example device.Type: GrantFiled: December 23, 2019Date of Patent: July 25, 2023Assignee: Integrated Biometrics, LLCInventors: David A. Hardinger, Spencer R. Canizales, Sang Hoon Chae, Frederick Frye, Dong Hyuk Jang, Robert A. Kimball

Publication number: 20160154170Abstract: Various applications and customizations of a thin flexible LED light sheet are described. Microscopic LED dice are printed on a thin substrate, and the LEDs are sandwiched between two conductor layers to connect the LEDs in parallel. The conductor layer on the light emitting side is transparent. In one embodiment, the light sheet is applied to the bottom surface of a controllable display to serve as a backlight. In another embodiment, the light sheet is applied to the edge of a leaky light guide for backlighting. In another embodiment, a thin light-emitting edge of the light sheet is coupled to the edge of the leaky light guide for backlighting. In another embodiment, the light sheet is affixed to a medical instrument, and light is emitted from a thin light-emitting edge of the light sheet. In one embodiment, the light sheet is optically coupled to an optical fiber.Type: ApplicationFiled: February 3, 2016Publication date: June 2, 2016Inventors: Travis Thompson, Bradley S. Oraw, Alexander Ray, Andrew Dennis, Mark D. Lowenthal, Sarah Behm Thompson, William J. Ray, Richard A. Blanchard, Neil O. Shotton, Tammie Woolgar, Joseph Nathan, Jeffrey Baldridge, David Hardinger

Patent number: 8507047Abstract: An approach is described for manufacturing wavelength conversion components for lighting devices which employ in-line process controls to minimize the amount of perceptible variation in the amount of photo-luminescent material that is deposited in the wavelength conversion components. Weight measurements are utilized in the manufacturing process to control and minimize the amount of the variations. In this approach, the weight of the product during manufacturing is used as a surrogate to a measure of the amount of photo-luminescent material in the component, and hence a surrogate for the expected color properties of the manufactured product. By measuring and checking for weight variations for the component, one can quickly determine with reasonable confidence whether there are any variations in the amount of photo-luminescent in the component.Type: GrantFiled: October 13, 2011Date of Patent: August 13, 2013Assignee: Intematix CorporationInventors: David A. Hardinger, Charles Edwards

Publication number: 20090179870Abstract: A luminous touch screen includes a light guide having a light extracting feature on a first major surface and an interstitial layer on a second major surface. A touch screen overlies the interstitial layer. The light guide has an index of refraction, n1, the interstitial layer has an index of refraction, n2, and n1>n2. The interstitial layer is preferably a layer of resin bearing ink, which is cured or dried after deposition.Type: ApplicationFiled: January 16, 2008Publication date: July 16, 2009Applicant: World Properties, Inc.Inventors: Willaim F.
