Patent number: 11987431Abstract: A top-opening substrate carrier comprises a container body, a door member and at least one latching mechanism. The latching mechanism includes a rotary drive member, a first driven cam, a second driven cam, a first connecting rod, a second connecting rod, two longitudinal latching arms and two lateral latching arms. The first driven cam and the second driven cam are disposed at two sides of the rotary drive member. When the rotary drive member is rotated by force, it links and activates the first connecting rod and the second connecting rod to synchronously drive the first driven cam and the second driven cam to rotate, thereby driving the two longitudinal latching arms and the two lateral latching arms to project towards locking holes of the container body and locked, or retract from the locking holes of the container body and unlocked.Type: GrantFiled: March 27, 2023Date of Patent: May 21, 2024Assignee: GUDENG PRECISION INDUSTRIAL CO., LTD.Inventors: Ming-Chien Chiu, Yung-Chin Pan, Cheng-En Chung, Chih-Ming Lin, Po-Ting Lee, Wei-Chien Liu, Tzu-Ning Huang

Patent number: 11960106Abstract: The disclosure provides an augmented reality (AR) device, a notebook, and smart glasses. The AR device includes a laser source, a spatial light modulator (SLM), and a hologram optical element (HOE). The laser source provides a coherent laser ray. The SLM provides a diffraction pattern solely corresponding to the coherent laser ray. When the SLM receives the coherent laser ray, the diffraction pattern diffracts the coherent laser ray as a hologram in response to the coherent laser ray. The HOE provides a concave mirror effect merely in response to a wavelength of the coherent laser ray, wherein the HOE receives the hologram and magnifies the hologram as a stereoscopic virtual image.Type: GrantFiled: December 31, 2019Date of Patent: April 16, 2024Assignee: Acer IncorporatedInventors: Yi-Jung Chiu, Wei-Kuo Shih, Shih-Ting Huang
