Patent number: 11825408Abstract: Systems, methods, and computer-readable media for controlling link selection and aggregation across multiple wireless networks based on a location of a mobile device. A location of a mobile device in a physical environment can be identified. At least portions of the physical environment can be in wireless range of a first wireless network and a second wireless network. Whether to access network services through either or both the first wireless network and the second wireless network can be determined based on the location of the mobile device in the physical environment. Further, a first interface at the mobile device to the first wireless network and a second interface at the mobile device to the second wireless network can be selectively toggled according to whether it is determined to access the network services through either or both the first wireless network and the second wireless network based on the location.Type: GrantFiled: May 18, 2022Date of Patent: November 21, 2023Assignee: Cisco Technology, Inc.Inventors: Malcolm Muir Smith, Jerome Henry, John George Apostolopoulos

Publication number: 20230254687Abstract: Correlating devices and clients across addresses may be provided. A first address associated with a client device may be received. When the client device is not connected to a network, first location data associated with the first address may be obtained using a passive technique. A second address and second location data associated with the second address may then be obtained using an active technique. It may then be determined that the first location data and the second location data correlate. In response to determining that the first location data and the second location data correlate, it may be determined that the client device has changed from the first address to the second address.Type: ApplicationFiled: April 17, 2023Publication date: August 10, 2023Applicant: Cisco Technology, Inc.Inventors: John Martin Graybeal, Jerome Henry, Paul Anthony Polakos, Louis Gwyn Samuel, John George Apostolopoulos

Patent number: 11463557Abstract: In one embodiment, a device in a serial network de-multiplexes a stream of traffic in the serial network into a plurality of data streams. The device determines that data from a particular data stream should be reported to an entity external to the serial network based on an event indicated by the data from the particular data stream. The device quantizes the data from the particular data stream. The device applies compression to the quantized data to form a compressed representation of the particular data stream. The applied compression is selected based on a data type associated with the data. The device sends a compressed representation of the particular data stream to the external entity as Internet Protocol (IP) traffic.Type: GrantFiled: December 21, 2020Date of Patent: October 4, 2022Assignee: Cisco Technology, Inc.Inventors: David A.

Patent number: 11021074Abstract: In one embodiment, a device obtains sensor data indicative of three dimensional (3-D) orientations of primary and secondary wireless power transfer (WPT) charging coils. The secondary coil is mounted to a vehicle and the primary coil provides charge to the secondary coil during charging. The device detects misalignment between the primary and secondary WPT coils based on the sensor data. The device determines a coil alignment correction to offset the detected misalignment. The device sends control commands to one or more actuators to implement the coil alignment correction by moving one or more of the coils, either directly (e.g., via directly-coupled actuators) or indirectly (e.g., via the suspension of a vehicle).Type: GrantFiled: June 19, 2018Date of Patent: June 1, 2021Assignee: Cisco Technology, Inc.Inventors: Ashok Krishnaji Moghe, John George Apostolopoulos, Charles Calvin Byers

Patent number: 11001158Abstract: In one embodiment, a static wireless power transfer (WPT) system (with charging spots and non-charging parking spots) receives a request to charge a vehicle. The device schedules a period of time during which the vehicle is allocated access to a particular charging spot based on scheduling characteristics and one or more other vehicles also requesting charging. The device may then send instructions to control the vehicle to autonomously move from a current parking spot to the particular charging spot for the scheduled period of time, the instructions precisely aligning the vehicle in the particular charging spot for optimum power transfer based on a charging coil of the vehicle and a respective ground-based charging coil of the particular charging spot. After the scheduled period of time, the device may send additional instructions to control the vehicle to autonomously move out of the particular charging spot.Type: GrantFiled: January 4, 2018Date of Patent: May 11, 2021Assignee: Cisco Technology, Inc.Inventors: Ashok Krishnaji Moghe, John George Apostolopoulos

Patent number: 11005697Abstract: Orthogonal frequency-division multiplexing (OFDM) equalization using a Deep Neural Network (DNN) may be provided. First, a signal in a packet structure may be received at an OFDM receiver from an OFDM transmitter. The signal may have distortion. Training constellation points, pilot constellation points, and data constellation points may be extracted from the signal based on the packet structure. Each data constellation point may correspond to a data subcarrier within a data symbol of the signal. Next, the training constellation points and the pilot constellation may be provided as input for the data symbol to a DNN. A coefficient for each data subcarrier within the data symbol that reverses the distortion may be received as output from the DNN. Then, the coefficient for each data subcarrier may be applied to the corresponding data constellation point to determine a per subcarrier constellation point prediction.Type: GrantFiled: September 3, 2019Date of Patent: May 11, 2021Assignee: CISCO TECHNOLOGY, INC.Inventors: Robert Edward Liston, John George Apostolopoulos
