Publication number: 20220050298Abstract: A wearable display system includes one or more emissive micro-displays, e.g., micro-LED displays. The micro-displays may be monochrome micro-displays or full-color micro-displays. The micro-displays may include arrays of light emitters. Light collimators may be utilized to narrow the angular emission profile of light emitted by the light emitters. Where a plurality of emissive micro-displays is utilized, the micro-displays may be positioned at different sides of an optical combiner, e.g., an X-cube prism which receives light rays from different micro-displays and outputs the light rays from the same face of the cube. The optical combiner directs the light to projection optics, which outputs the light to an eyepiece that relays the light to a user's eye. The eyepiece may output the light to the user's eye with different amounts of wavefront divergence, to place virtual content on different depth planes.Type: ApplicationFiled: December 20, 2019Publication date: February 17, 2022Inventors: Michael Anthony Klug, Evgeni Poliakov, Jahja I.

Publication number: 20200326546Abstract: A method and system for increasing dynamic digitized wavefront resolution, i.e., the density of output beamlets, can include receiving a single collimated source light beam and producing multiple output beamlets spatially offset when out-coupled from a waveguide. The multiple output beamlets can be obtained by offsetting and replicating a collimated source light beam. Alternatively, the multiple output beamlets can be obtained by using a collimated incoming source light beam having multiple input beams with different wavelengths in the vicinity of the nominal wavelength of a particular color. The collimated incoming source light beam can be in-coupled into the eyepiece designed for the nominal wavelength. The input beams with multiple wavelengths take different paths when they undergo total internal reflection in the waveguide, which produces multiple output beamlets.Type: ApplicationFiled: April 28, 2020Publication date: October 15, 2020Applicant: Magic Leap, Inc.Inventors: Lionel Ernest EDWIN, Ivan Li Chuen YEOH, Brian T.

Publication number: 20200201026Abstract: Techniques for artifact mitigation in an optical system are disclosed. Light associated with a world object is received at the optical system, which is characterized by a world side and a user side. Light associated with a virtual image is projected onto an eyepiece of the optical system, causing a portion of the light associated with the virtual image to propagate toward the user side and light associated with an artifact image to propagate toward the world side. A dimmer of the optical system positioned between the world side and the eyepiece is adjusted to reduce an intensity of the light associated with the artifact image impinging on the dimmer and an intensity of the light associated with the world object impinging on the dimmer.Type: ApplicationFiled: December 17, 2019Publication date: June 25, 2020Applicant: Magic Leap, Inc.Inventors: Kevin Richard Curtis, Samarth Bhargava, Bradley Jay Sissom, Victor Kai Liu, Chulwoo Oh, Ravi Kumar Komanduri, Kevin Messer

Publication number: 20200184394Abstract: A service provider system may implement an enterprise catalog service that manages software products and portfolios of software products on behalf of service provider customer organizations. Through an administrator interface of the service, a customer organization administrator may create constraints on the use of the software products, and each constraint may include one or more rules about how the products can be launched. These may include environmental constraints (specifying a region in which a product launches), restrictions on input parameter values (including the types of resource instances on which a product can be launched), quotas (controlling the number of product installations), or billing constraints. Constraints may be applied on a user-to-product arc or on a portfolio-to-product arc. Constraints may be stored as objects, and reference to those objects may be added to product or portfolio objects.Type: ApplicationFiled: February 14, 2020Publication date: June 11, 2020Applicant: Amazon Technologies, Inc.Inventors: Frederik Christophe Delacourt, Quan Binh To, Christopher Whitaker, Richard Curtis Edwards, JR., Julien Jacques Ellie, Zachary Thomas Crowell, Benjamin David Newman
