Patent number: 11829841Abstract: A mechanical energy-based self-powering counting system is provided. The system includes an electromagnetic power generator, a count measuring circuit, a count energy supply circuit, a controller and a wireless transmission module. The electromagnetic power generator is driven by an external device and produces an electric signal and outputs the electric signal to the controller after passing it through the count measuring circuit. The controller processes the received signal, updates a count according to certain programming rules and sends data to the wireless transmission module. The energy from the electromagnetic power generator flowing through the count measuring circuit can supply power to the controller. An energy storage module in the count energy supply circuit performs voltage feedback on the controller. The controller monitors the voltage of the energy storage module to control whether it enters a charging state.Type: GrantFiled: September 7, 2021Date of Patent: November 28, 2023Assignee: Beijing Institute of TechnologyInventors: Fang Deng, Yeyun Cai, Ning Ding, Chengwei Mi, Jiachen Zhao, Xianghu Yue, Bin Zhang, Chen Chen, Wenjie Chen, Jia Zhang, Jie Chen

Patent number: 11762806Abstract: A system clock is protected by limiting clock changes, change frequency, and calculating skew. System and secure clocks are initialized to a same time. First and second thresholds are set. The first threshold corresponds to an alert and the second threshold corresponds to an action. At a time interval at which the secure clock is to be updated, a skew is calculated between the system and secure clocks, and a cumulative skew is calculated. Upon a determination that the cumulative skew has reached the first threshold, but not the second threshold, the alert is triggered while deletions of files having retention locks that have expired according to the system clock are allowed to continue. Upon a determination that the cumulative skew has reached the second threshold, the action is triggered. The action includes blocking the deletions of files having retention locks that have expired according to the system clock.Type: GrantFiled: October 15, 2020Date of Patent: September 19, 2023Assignee: EMC IP Holding Company LLCInventors: Jagannathdas Rath, Kalyan C Gunda, Rekha Sampath, Satish Inampudi, Senthil Ponnuswamy, Sophie Syau Fang Deng
