Publication number: 20230256327Abstract: A visual guidance-based mobile game system (001) comprises a terminal (100) and a gamepad (200) connected with the terminal (100). The terminal (100) comprises a user interface module configured to receive an eye movement image and output a mobile game response. The mobile game system (001) further comprises a visual intelligent guidance module (210) and a data processing module (220) that are connected with the user interface module (120). The eye tracker converts the eye movement image into the eye tracking information. The visual intelligent guidance module (210) is configured to transmit the eye tracking information to the data processing module (220). The data processing module (220) is configured to determine a responsive instruction corresponding to the eye tracking information according to the eye tracking information, so as to guide a control point on a screen of the terminal according to the responsive instruction and complete the mobile game response.Type: ApplicationFiled: November 7, 2020Publication date: August 17, 2023Applicant: GOERTEK INC.Inventors: Tiancui MENG, Songyang LI

Patent number: 9128260Abstract: In one embodiment, an optical subassembly includes a housing, a ball lens, a constraining insert, and a ball lens constraint. The housing includes a fiber receptacle formed in a first end of the housing and a second receptacle formed in a second end of the housing opposite the first end. The fiber receptacle and second receptacle define a cavity through the housing from the first end to the second end of the housing. The ball lens and the constraining insert are disposed within the cavity. The ball lens constraint is configured to cooperate with the constraining insert to constrain the ball lens in three dimensions within the cavity.Type: GrantFiled: November 10, 2014Date of Patent: September 8, 2015Assignee: FINISAR CORPORATIONInventors: Stefan M.

Patent number: 7597486Abstract: In one example, an optical device includes a body having a first surface and a second surface. At least a portion of the body is formed from a material that is transmissible to light. The body is configured to be positioned in an optical sub-assembly along an axis defined between an optoelectronic transducer and a port configured to receive an optical fiber. The axis is defined between a point on an optically active portion of the optoelectronic transducer and a point on a surface of the optical fiber. The first surface of the body is positioned at a first angle relative to a plane that is perpendicular to the axis. The second surface of the body is positioned at a second angle relative to the plane. The first surface and the second surface are positioned at respective opposing ends of the body.Type: GrantFiled: September 28, 2007Date of Patent: October 6, 2009Assignee: Finisar CorporationInventors: Tat Ming Teo, Wendy Pei Fen Lau, Songyang Li
