Patent number: 11729864Abstract: A network server selects a gateway, from among a plurality of alternative candidate gateways, to use for downlink wireless communication to an end node (EN) based on additional factors in addition to RSSI. Exemplary additional factors include: SNR, gateway loading, message loading, backhaul network loading, device type, application type, application priority, operator preferences, device/application black-lists, white-lists, and red-lists, number of devices, number of transmitting devices in a given time interval, operator rules and priorities. In some embodiments, the network server calculates a composite weighted metric (CWM) for each of the alternative candidate gateways which may be used for downlink, subject to operator policy rules, and selects to use a gateway based on the results, e.g. selects the gateway with the highest CWM.Type: GrantFiled: April 25, 2022Date of Patent: August 15, 2023Assignee: Charter Communications Operating, LLCInventors: Umamaheswar Achari Kakinada, Hossam Hmimy, Wael Guibene, Muhammad Khan

Patent number: 11729092Abstract: The disclosed invention provides system and method for multi-path mesh network communications. The network system utilizes multiple communication paths and linearly encoded and disassembled packets through mathematical coding techniques that respectively travel the communication paths. The system includes an encoder, a transmitter, a decoder and a receiver. The encoder receives data from an external source and linearly encodes and simultaneously disassembles the data to generate copackets. None of the individual copackets contain decodable information of the data. The transmitter is coupled to the multiple communication paths and respectively transmits the copackets through different communication paths. The receiver receives the copackets transmitted through the communication paths. The decoder decodes available copackets and reassembles the data from the available copackets if a number of the available copackets are no less than a mathematically calculated number.Type: GrantFiled: July 2, 2020Date of Patent: August 15, 2023Assignee: Northrop Grumman Systems CorporationInventors: Garrett Rosich, Peter Houser, Bob Caulfield, Matthew Houser

Patent number: 11726933Abstract: An I/O server service interacts with multiple containerized controller services each implementing the same control routine to control the same portion of the same plant. The I/O server service may provide the same controller inputs to each of the containerized controller services (e.g., representing measurements obtained by field devices and transmitted by the field devices to the I/O server service). Each containerized controller service executes the same control routine to generate a set of controller outputs. The I/O server service receives each set of controller outputs and forwards an “active” set to the appropriate field devices. The I/O server service and other services, such as an orchestrator service, may continuously evaluate performance and resource utilization in the control system, and may dynamically activate and deactivate controller services as appropriate.Type: GrantFiled: October 19, 2021Date of Patent: August 15, 2023Assignee: FISHER-ROSEMOUNT SYSTEMS, INC.Inventors: Anthony Amaro, Jr., Mark J.
