Publication number: 20230209261Abstract: A speaker apparatus includes a pair of left and right speaker blocks that respectively have acoustic output sections and that are arranged inside a backrest. The pair of speaker blocks are arranged horizontally side by side relative to a headrest located on a front surface side of the backrest, and at least part of the headrest is located within a range of a nominal directivity angle of acoustics output from the acoustic output sections. This ensures that, of the acoustics output from the acoustic output section of the speaker block on the left side, at least some acoustics that head for the right ear are blocked by the headrest and that, of the acoustics output from the acoustic output section of the speaker block on the right side, at least some acoustics that head for the left ear are blocked by the headrest.Type: ApplicationFiled: April 20, 2021Publication date: June 29, 2023Inventors: ATSUSHI HOMMA, TAKAHIRO HAYASAKA

Patent number: 11122257Abstract: A method, apparatus and system for enhanced welding visualization include splitting incoming light from the welding environment into at least a first optical path and a second optical path having different light levels using at least one beam splitter. Images of the split light having different light levels are captured using a respective imaging sensor. The images from the respective imaging sensors are fused to create a left-eye fused image and a right-eye fused image. The left-eye fused image is displayed on a display at a location of a left eye of a user and the right-eye fused image is displayed on a display at a location of a right eye of the user to provide a parallax-free, high dynamic range, representation of the welding environment.Type: GrantFiled: May 23, 2019Date of Patent: September 14, 2021Assignee: SRI InternationalInventors: David Berends, Naohiko Fuse, Atsushi Homma, Noriyuki Kanehira, Tadahisa Tsuyama, Michael Piacentino, Gooitzen van der Wal, Chiharu Yamaoka, David Zhang
