Publication number: 20220394092Abstract: The concepts and technologies disclosed herein are directed to proximity routing policy enforcement for trans-border Internet of Things (“IoT”) data governance compliance. A network gateway can receive, from a data source device, a device registration message comprising a device registration header. The network gateway can determine, based upon the device registration header and a data governance policy, whether the data source device is permitted to access a data governance zone. In response to determining that the data source device is permitted to access the data governance zone, the network gateway can determine, based upon a further data governance policy, at least one gateway of a plurality of gateways operating in the data governance zone to which the device registration message is to be forwarded. The network gateway can forward the registration message to the at least one gateway so that the at least one gateway is enabled for device operation.Type: ApplicationFiled: August 15, 2022Publication date: December 8, 2022Applicants: AT&T Global Network Services Hong Kong LTD, AT&T Mobility II LLCInventors: Winnie Chau, John Philip Mulligan, Shashi Gowda

Publication number: 20220375161Abstract: Techniques are disclosed relating to arbitration for computer memory resources. In some embodiments, an apparatus includes queue circuitry that implements multiple queues configured to queue requests to access a memory bus. Control circuitry may, in response to detecting a first threshold condition associated with the queue circuitry, generate a first snapshot that indicates numbers of requests in respective queues of the multiple queues at a first time. The control circuitry may generate a second snapshot that indicates numbers of requests in respective queues of the multiple queues at a second time that is subsequent to the first time. The control circuitry may arbitrate between requests from the multiple queues to select requests to access the memory bus, where the arbitration is based on snapshots to which requests from the multiple queues belong. Disclosed techniques may approximate age-based scheduling while reducing area and power consumption.Type: ApplicationFiled: August 1, 2022Publication date: November 24, 2022Inventors: Winnie W.

Publication number: 20220374359Abstract: Techniques are disclosed relating to multi-block fetches for cache misses. In some embodiments, cache tag circuitry maintains a tag value that is shared by multiple cache blocks. In response to a miss, the cache may initiate a fetch request to a next level cache or memory. Aggregation circuitry may aggregate multiple fetch requests for cache blocks that share the tag value and fetch circuitry may initiate a single multi-block fetch operation to the next level cache or memory that returns cache blocks for the aggregated multiple fetch requests. In various embodiments, disclosed techniques may improve performance (e.g., by reducing fetch bus transactions), reduce power consumption, or both, relative to traditional techniques.Type: ApplicationFiled: May 19, 2021Publication date: November 24, 2022Inventors: Winnie W.

Patent number: 11504194Abstract: Systems and methods according to present principles provide for three axis force sensing in a convenient and manufacturable way. In one implementation, a vibrating motor is attached at the fixed end of an anisotropic structure, such as a rod, which then vibrates in a circular motion. A monitor such as a 3-axis accelerometer is also attached to the anisotropic structure. The resulting motion is then mapped electronically for analysis. With no force applied, a circular motion is achieved. When a net force is applied to the free, vibrating end of the rod, the circular pattern which is traced out becomes distorted, e.g., progressively flattened into an ellipse, in a repeatable way which is directly proportional to the applied force. The axis of the applied force can be ascertained according to the direction in which the ellipse forms. Systems and methods according to present principles may be used in any application in which force sensing is needed, e.g., robotics, including robotic surgery.Type: GrantFiled: December 13, 2017Date of Patent: November 22, 2022Assignee: The Regents of the University of CaliforniaInventors: Michael Yip, Jun Zhang, Alex Tran, Winnie Kuang
