Publication number: 20230144230Abstract: A rehabilitation system based on brainwave control includes a rehabilitation device, a brainwave device and a control unit. The rehabilitation device includes a power unit and a rehabilitation unit. The control unit is coupled with the rehabilitation device and the brainwave device. In a state where the power unit provides the predetermined output to control the rehabilitation unit to drive the rehabilitation part to move, the control unit receives the brainwave signal and determines whether the brainwave signal is lower than a stimulation threshold. In a state where the brainwave signal is lower than the stimulation threshold, the control unit sends an adjustment signal to control the power unit to adjust the predetermined output to drive the rehabilitation unit to move.Type: ApplicationFiled: June 6, 2022Publication date: May 11, 2023Inventors: Chia-Hsin CHEN, Li-Wei KO, Yi-Jen CHEN, Yi-Chen LU, Lo-Fan CHANG

Patent number: 11328112Abstract: In order to expedite testing (such as silicon chip testing), a test pattern that indicates a timing, order, and frequency (e.g., speed) of signals sent during the test may be divided into different portions. Also, a frequency at which each portion of the test pattern is to be run is determined. Each portion is run at a frequency that can be supported by only that portion. As a result, the slowest portion of the test pattern only limits the frequency at which its portion is run, while other portions are run at a faster frequency. This reduces a time taken to run the test pattern in a testing environment.Type: GrantFiled: January 27, 2021Date of Patent: May 10, 2022Assignee: NVIDIA CORPORATIONInventors: Shang-Ju Lee, Li-Wei Ko, Francisco M.
