Patent number: 11586031Abstract: An optical imager system and method of operating the optical imager system, can include one or more imager modules including a laser light source, a collimator, an illumination optical system, a grating light valve, a spatial light modulator and a projection optical system. A group of imager modules can include the one or more imager modules. The group of imager modules is operable in a stacked arrangement to produce an image from in-line stitching of individual images generated by the one or more imager modules. The illumination optical system can homogenize, shape, and direct a beam from the laser light source onto the grating light valve, and homogenization can occur in a cross-process direction.Type: GrantFiled: July 8, 2020Date of Patent: February 21, 2023Assignee: XEROX CORPORATIONInventor: Patrick Y. Maeda

Patent number: 11528458Abstract: An image display apparatus includes a light source, an image generation unit which generates image light, and a projection optical system including a first lens system which refracts the image light, a first reflection optical system having two or more reflection surfaces that fold back and reflect the refracted image light, a second lens system which refracts the image light reflected by the first reflection optical system, and a second reflection optical system which reflects the image light refracted by the second lens system toward a projection object. The first reflection optical system includes an optical component having a principal surface on which one of the reflection surfaces is configured. The principal surface includes a transmission surface that allows the image light to pass therethrough, configured in a region having a shape rotationally asymmetric to the reflection surface with respect to an optical axis of the optical component.Type: GrantFiled: November 18, 2019Date of Patent: December 13, 2022Assignee: Sony Group CorporationInventors: Jun Nishikawa, Naoko Edamitsu

Patent number: 11528528Abstract: The invention provides a method and a system for controlling a projector. The control method includes: obtaining a first trigger rule and a first to-be-executed action corresponding to the first trigger rule. The first trigger rule and the first to-be-executed action respectively include at least one of a plurality of combinable elements. The control method includes: determining whether the first trigger rule is satisfied and controlling the projector to execute the first to-be-executed action when the first trigger rule is determined as being satisfied. The control system includes a projector and a control device configured to execute the control method. The control method and system of the invention provide more diverse and flexible rules and action generation mechanisms, thereby implementing effects of product differentiation and intelligent operation.Type: GrantFiled: November 22, 2020Date of Patent: December 13, 2022Assignee: Coretronic CorporationInventor: Cheng-Tao Ho
