Patent number: 10302947Abstract: A head mounted display device comprises an optical combiner that combines light from a display and light from an environment into light transmitted towards a user's eye. A controllable optical element located in the light path from the environment, optically between the environment and the optical combiner, for passing light from the environment switchable between filtering and not filtering by optical blurring or diffusion. The device comprises a camera directed at the environment. A control circuit uses image data from the camera to compute a measure of contrast and/or a measure of luminance in a measurement region within an image or images captured by the camera and applies a control signal to the control input dependent on the measure of contrast and/or the measure of luminance. This is used to create or increase the filtering effect of controllable optical element with an increase of the measure of contrast and/or the measure of luminance.Type: GrantFiled: September 22, 2015Date of Patent: May 28, 2019Assignee: Nederlandse Organisatie voor toegepast-natuurwetenschappelijk onderzoek TNOInventors: Frank Leonard Kooi, Anton Havekes

Publication number: 20140249248Abstract: The present disclosure provides an inkjet ink comprising an aqueous vehicle and an encapsulated pigment dispersion. A process for encapsulating pigment dispersions is provided where a pigment is dispersed with a polymeric dispersant in an aqueous solvent system. The encapsulation process has at least two additions of encapsulating monomers followed by polymerization. To a pigment dispersed with a polymeric dispersant is added an encapsulating monomer(s) and a polymerization initiator is added which forms a stage 1 encapsulated pigment. Then a second encapsulating monomer(s) is added and these monomers are polymerized by a second addition of polymerization initiator, forming a second stage encapsulated pigment. The second encapsulating monomer(s) may be added continuously to the stage 1 encapsulated pigment. Such encapsulated pigment dispersions may be used in inkjet inks and are stable to heat, aging test conditions, and solvent challenges. Prints from these inks have better durability.Type: ApplicationFiled: December 15, 2011Publication date: September 4, 2014Applicant: E I DU PONT DE NEMOURS AND COMPANYInventors: Hee Hyun Lee, Frank Leonard Schadt, Michael Stephen Wolfe
