Patent number: 11916471Abstract: An example electronic device includes a controller to determine a user touch detection by a power adaptor coupled to the electronic device to operate the electronic device in an AC power mode. The power adaptor may comprise a proximity sensor to detect a user touch for detachment of the power adaptor from the electronic device, and a control circuit to operate a configuration pin in a low output mode to signal user touch detection. The controller may initiate central processing unit (CPU) throttling to reduce power consumption by the electronic device. The controller may further stop CPU throttling in response to detecting that the power adaptor has been detached from the electronic device. Further, the controller may switch the electronic device to a DC power mode to operate using DC power supplied by a battery of the electronic device in response to power adaptor detachment.Type: GrantFiled: October 18, 2019Date of Patent: February 27, 2024Assignee: Hewlett-Packard Development Company, L.P.Inventors: Ting-Yang Tsai, Yi-Chen Chen, Ching-Lung Wang, Yu-Min Shen

Patent number: 7553530Abstract: A waved mesh tube including multiple parallel first strings spirally extending in a first direction and multiple parallel second strings spirally extending in a second direction. The second strings are laid on the first strings. The mesh tube has continuous circles of waved bending sections arranged along an axis of the mesh tube. The mesh tube is formed with the bending sections so that the wall of the mesh tube has multiple wave crests and wave troughs adjoining each other. The wave troughs define an inner diameter of the mesh tube, while the wave crests define an outer diameter of the mesh tube. Each of the wave crests and the wave troughs has an acute angle. A difference between the inner diameter and the outer diameter is a thickness of the wall of the mesh tube. The wall of the mesh tube is waved and solid and has higher rigidity.Type: GrantFiled: March 7, 2006Date of Patent: June 30, 2009Inventor: Ching Chen Chen
