Patent number: 11962087Abstract: This document describes a single-layer air waveguide antenna integrated on a circuit board. The waveguide guides electromagnetic energy through channels filled with air. It is formed from a single layer of material, such as a sheet of metal, metal-coated plastic, or other material with conductive surfaces that is attached to a circuit board. A portion of a surface of the circuit board is configured as a floor of the channels filled with air. This floor is an electrical interface between the circuit board and the channels filled with air. The single layer of material is positioned atop this electrical interface to define walls and a ceiling of the channels filled with air. The single layer of material can be secured to the circuit board in various ways. The cost of integrating an air waveguide antenna on to a circuit board this way may be less expensive than other waveguide-manufacturing techniques.Type: GrantFiled: February 1, 2023Date of Patent: April 16, 2024Assignee: Aptiv Technologies AGInventors: Scott D.

Publication number: 20230333369Abstract: Optical systems and methods for operation thereof are disclosed. A delimited zone is defined as a function of distance from the optical system based on a VAC limit, the delimited zone having at least one distance threshold. A virtual distance of a virtual depth plane from the optical system at which a virtual object is to be displayed is determined. It is determined whether the virtual distance is outside the delimited zone by comparing the virtual distance to the at least one distance threshold. A collimated pixel beam associated with the virtual object is generated by a projector of the optical system. The collimated pixel beam is modified to generate a modified pixel beam if the virtual distance is outside the delimited zone. Modifying the collimated pixel beam includes converging the collimated pixel beam and/or reducing a diameter of the collimated pixel beam.Type: ApplicationFiled: June 23, 2023Publication date: October 19, 2023Applicant: Magic Leap, Inc.Inventors: Michael Anthony Klug, William Hudson Welch, Jason Schaefer, Björn Nicolaas Servatius Vlaskamp, Robert D.

Publication number: 20230280594Abstract: 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: May 11, 2023Publication date: September 7, 2023Applicant: Magic Leap, Inc.Inventors: Lionel Ernest Edwin, Ivan Li Chuen Yeoh, Brian T.
