Patent number: 11905970Abstract: A diffuser includes a lower element and an upper element. The upper element is fixed on the lower element, and the upper element and the lower element are formed separately. The lower element includes a lower inner wall and a lower outer wall, and the upper element includes an upper inner wall and an upper outer wall. The upper inner wall is connected to the lower inner wall to form an internal air-guiding surface, the upper outer wall is connected to the lower outer wall to form an external air-guiding surface, and the internal air-guiding surface is disposed opposite to the external air-guiding surface to define an air-guiding channel for air flow diffusion. The upper element further includes an upper air-guiding wing for connecting the upper inner wall and the upper outer wall, and the lower element further includes a lower air-guiding wing for connecting the lower inner wall and the lower outer wall.Type: GrantFiled: March 16, 2020Date of Patent: February 20, 2024Assignees: GD MIDEA ENVIRONMENT APPLIANCES MFG CO., LTD., MIDEA GROUP CO., LTD.Inventors: Hai Dou, Lie Ma, Chen Shao

Publication number: 20050203968Abstract: A method for controlling the update installation behavior of a computing device according to installation attributes is presented. When present, a mandatory installation attribute associated with a software update causes the installation process executed on the computing device to disallow a user to selectively not install the software update. A priority installation attribute causes the computing device to request a higher amount of network bandwidth for obtaining the software update's content for installation on the client computing device. A deadline installation attribute associated with the software update causes the computing device to permit a user to selectively not install the software update until an associated deadline passes, at which time the software update is installed without further user interaction.Type: ApplicationFiled: March 12, 2004Publication date: September 15, 2005Inventors: David Dehghan, Edward Reus, Nirmal Soy, Lie Ma, Marc Shepard, Jianbo Hou, David Hennessey, Varadarajan Thiruvillamalai, Vidyasankar Raman, Thottam Sriram, Jason Roberts, Mazhar Mohammed, Xiang He
