Patent number: 11942791Abstract: A self-powered wireless keyboard by modifying the structure of a traditional membrane keyboard having a volcanic crater structure. Not damaging the original membrane keyboard structure, a micro magnet core is installed inside a cylindrical protrusion block under the key cap as a mover of the induction power generation device, and an induction coil is wound in a key slot of the keyboard base as the stator of the induction power generation device. In this way, when each key is pressed, it will produce induction current. A layer of flexible solar cell can be laid on the upper surface of the key, which can generate electricity by collecting the light energy in the surrounding environment during the time of daily illumination.Type: GrantFiled: September 26, 2021Date of Patent: March 26, 2024Assignee: Beijing Institute of TechnologyInventors: Fang Deng, Yanxin Ji, Xinyu Fan, Yeyun Cai, Chengwei Mi, Feng Gao, Jie Chen, Lihua Dou

Patent number: 11570024Abstract: Equalization methods and equalizers employing discrete-time filters are provided with dynamic perturbation effect based adaptation. Tap coefficient values may be individually perturbed during the equalization process and the effects on residual ISI monitored to estimate gradient components or rows of a difference matrix. The gradient or difference matrix components may be assembled and filtered to obtain components suitable for calculating tap coefficient updates with reduced adaptation noise. The dynamic perturbation effect based updates may be interpolated with precalculated perturbation effect based updates to enable faster convergence with better accommodation of analog component performance changes attributable to variations in process, supply voltage, and temperature.Type: GrantFiled: November 1, 2021Date of Patent: January 31, 2023Assignee: CREDO TECHNOLOGY GROUP LIMITEDInventors: Fang Cai, Junqing (Phil) Sun, Haoli Qian
