Publication number: 20240316457Abstract: An example of an image display system includes a goggle apparatus including a display section. A virtual camera and a user interface are placed in a virtual space. In accordance with the orientation of the goggle apparatus, the orientation of the virtual camera in the virtual space is controlled. For example, in a case where the line of sight of the virtual camera rotates in a left direction in a yaw direction and then reverses in a right direction, and when the amount of change in the right direction is greater than or equal to a threshold, the user interface is moved to the front of the virtual camera.Type: ApplicationFiled: June 5, 2024Publication date: September 26, 2024Inventors: Yuki ONOZAWA, Daigo SHIMIZU, Kentaro KAWAI

Patent number: 12044555Abstract: A processing device of a displacement detection device includes an AD conversion device, a switching circuit, and an arithmetic processing unit. The AD conversion device has first and second AD conversion units. The switching circuit periodically switches between a first connection mode in which a first differential signal is AD-converted by the first AD conversion unit and a second differential signal is AD-converted by the second AD conversion unit, and a second connection mode in which the first differential signal is AD-converted by the second AD conversion unit and the second differential signal is AD-converted by the first AD conversion unit. The arithmetic processing unit outputs displacement information of a scale based on an addition average value of the first differential signals output from the first and second AD conversion units and an addition average value of the second differential signals output from the first and second AD conversion units.Type: GrantFiled: October 5, 2022Date of Patent: July 23, 2024Assignee: Murata Machinery, Ltd.Inventors: Tetsuya Shimizu, Kentaro Otomo, Ryohei Kido

Patent number: 12046703Abstract: A method includes depositing a layer comprising a photoinitiator and a curable material onto a surface and applying a nanoimprint mold on the layer of curable material to form a mesh comprising intersecting walls defining cavities. After applying the nanoimprint mold, the mesh is illuminated with light causing decarboxylation of the photoinitiator to initiate curing of the curable material. After curing the curable material, the nanoimprint mold is removed and a wavelength converting material is deposited in the cavities to form an array of wavelength converting pixels.Type: GrantFiled: April 7, 2023Date of Patent: July 23, 2024Assignee: Lumileds LLCInventors: Danielle Russell Chamberlin, Erik Roeling, Daniel Bernardo Roitman, Kentaro Shimizu

Patent number: 11973167Abstract: A method is described for low temperature curing of silicone structures, including the steps of providing patterning photoresist structures on a substrate. The photoresist structures define at least one open region that can be at least partially filled with a condensation cure silicone system. Vapor phase catalyst deposition is used to accelerate the cure of the condensation cure silicone, and the photoresist structure is removed to leave free standing or layered silicone structures.

Patent number: 11749787Abstract: An array of phosphor pixels is positioned on an array of semiconductor LED pixels with thermally curable adhesive between them. Selected LED pixels of the array are electrically activated; resulting heat cures the adhesive to attach the corresponding phosphor pixel to the activated LED pixel and to release the corresponding phosphor pixel from a carrier. Removal of the carrier removes unattached phosphor pixels, leaving behind phosphor pixels attached to the LED pixels that were activated. The process can be repeated for phosphor pixels of different colors.Type: GrantFiled: April 13, 2022Date of Patent: September 5, 2023Assignee: Lumileds LLCInventors: Emma Dohner, Kentaro Shimizu, Hisashi Masui

Patent number: 11585965Abstract: Described herein is a system and method for tuning light scatter in an optically functional porous layer of an LED. The layer comprises a non-light absorbing material structure having a plurality of sub-micron pores and a polymer matrix. The non-light absorbing material forms either a plurality of micron-sized porous particles dispersed throughout the layer or a mesh slab, wherein a plurality of sub-micron pores is located within each micron-sized porous particle or forms an interconnected network of sub-micron pores within the mesh slab, respectively. A polymer matrix, such as a high refractive index silicone fills the plurality of sub-micron pores creating an interface between the materials. Refractive index differences between the materials allow for light scatter to occur at the interface of the materials. Light scatter can also be decreased as a function of temperature, creating a system for tuning light scatter in both an off state and on state of an LED.Type: GrantFiled: August 11, 2020Date of Patent: February 21, 2023Assignee: Lumileds LLCInventors: Marcel Rene Bohmer, Jacobus Johannes Franciscus Gerardus Heuts, Daniel Estrada, Kentaro Shimizu
