Patent number: 11942285Abstract: An electronic device has a keyboard with an internal membrane. The membrane has a set of strain gauges configured to respond to a key press, such as when a collapsible dome collapses into contact with the membrane. The strain gauges are connected in a half Wheatstone bridge configuration and are positioned on the membrane in order to limit effects of temperature and subtle flexure of the membrane. The strain gauges are also configured to magnify detection of a resistance differential when a keycap is pressed with sufficient force.Type: GrantFiled: November 2, 2022Date of Patent: March 26, 2024Assignee: APPLE INC.Inventors: Chia Chi Wu, Michael Vosgueritchian, Ming Gao, Nan Chen, Vyom Sharma, Wenhao Wang

Publication number: 20240098125Abstract: The present disclosure relates to a system, a method and a computer-readable medium for rendering a streaming on a user terminal. The method includes rendering the streaming in a first mode, receiving an environment parameter of the user terminal, receiving a timing when the user terminal closes the streaming, determining a threshold value of the environment parameter based on the timing the user terminal closes the streaming, receiving an updated environment parameter of the user terminal, and rendering the streaming in a second mode if the updated environment parameter meets the threshold value. The second mode includes fewer data objects than the first mode or includes a downgraded version of a data object in the first mode for the rendering. The present disclosure can customize the rendering mode for each user and maximize the satisfaction of viewing streaming for each user.Type: ApplicationFiled: November 29, 2023Publication date: March 21, 2024Inventors: Yung-Chi HSU, Chung-Chiang HSU, Shao-Yuan WU, Ming-Che CHENG, Ka Chon LOI
