Patent number: 11568116Abstract: A true random metastable flip-flop (TRMFF) compiler generates an electrical architecture for a TRMFF chain. The compiler selects components for the TRMFF chain from a library of standard cells and logically connects these components in accordance with a primitive polynomial to generate the electrical architecture. The TRMFF chain provides a sequence of random numbers from one or more physical processes in accordance with the primitive polynomial. During operation, one or more microscopic phenomena inside and/or outside of the TRMFF chain can cause one or more low-level, statistically random entropy noise signals to be present within the TRMFF chain. The TRMFF chain advantageously utilizes the one or more low-level, statistically random entropy noise signals to provide the sequence of random numbers.Type: GrantFiled: December 26, 2019Date of Patent: January 31, 2023Assignee: Taiwan Semiconductor Manufacturing Co., Ltd.Inventors: Charlie Zhou, Tze-Chiang Huang, Jack Liu

Patent number: 11561809Abstract: Systems and methods for remote display resource management can allow a remote display to be dynamically modified according to user eye movements. A user device can receive graphical data for a remote display and present the remote display on a local display. A remote display module (RD module) can detect dynamic content in the graphical data. The RD module can monitor eye movements of a user using an eye tracker device to determine when a user is not looking at the dynamic content. When a user looks away from the dynamic content for more than an allowed amount of time, the RD module can send instructions to a server to reduce the quality of the dynamic content in the remote display. The RD module can send instructions to restore the quality of the dynamic content after determining that the user is looking at the dynamic content.Type: GrantFiled: July 5, 2021Date of Patent: January 24, 2023Assignee: VMware, Inc.Inventors: Jian Ken Song, Lin Lv, Jack Liu, Yue Sun, Sarah Cheng
