Patent number: 11941146Abstract: A container includes a user program and data generated by the user program within a regulatory jurisdiction. Before the container leaves the regulatory jurisdiction, the data is validated by the jurisdiction to ensure the data complies with privacy laws of the jurisdiction. Upon ingress to a second regulatory jurisdiction, the data is signed locally to provide for confirmation that the data can leave the second regulatory jurisdiction, since it was not generated within the second jurisdiction. By allowing the user program to move from the first regulatory jurisdiction to a second regulatory jurisdiction, the disclosed embodiments overcome limitations in current solutions that restrict access to local data based on what a public application programming interface (API) can provide. By operating within the regulatory jurisdiction, albeit subject to access controls imposed by that jurisdiction, flexibility in the processing of sensitive data is improved.Type: GrantFiled: August 31, 2021Date of Patent: March 26, 2024Assignee: CISCO TECHNOLOGY, INC.Inventors: Pascal Thubert, Patrick Wetterwald, Eric Levy- Abegnoli, Jonas Zaddach

Patent number: 11936453Abstract: Multi-User Multiple Input, Multiple Output (MU-MIMO) data transmissions are provided with a forward-predictive precoding matrix to mitigate the effects of a change in a state of a communication channel. First and second soundings are performed, at first and second times, to a receive antenna over a channel and, responsive to each of the soundings, first and second Channel State Information (CSI) are received. Based on the first and second CSI, a change in a state of the channel over a time period between the first and second time is determined. Based on the change in the state of the channel, a forward-predictive channel state matrix and/or a forward-predictive precoding matrix are determined that reflect a state of the channel at a future time and that are consistent with the determined change in the state over the time period. The forward-predictive precoding matrix is applied to a data transmission.Type: GrantFiled: February 2, 2021Date of Patent: March 19, 2024Assignee: Cisco Technology, Inc.Inventors: John Martin Graybeal, Paul Anthony Polakos, Robert Edward Liston, Wai-Tian Tan, Xiaoqing Zhu
