  • Patent number: 10912104
    Abstract: The present disclosure relates to an interleaved, static time division multiple access (TDMA) for communicating in a power delivery system. For example, an access point may communicate with a plurality of electronic devices in the power delivery system. The access point may send a first signal indicating a first poll to a first group of devices in the power delivery system to allow the first group of devices to communicate data to the access point during assigned time slots of the first group of devices. The access point may send a second signal indicating a second poll to a second group of devices, separate from the first group of devices, in the power delivery system to allow the second group of devices to communicate data to the access point during assigned time slots following the second poll.
    Type: Grant
    Filed: February 1, 2019
    Date of Patent: February 2, 2021
    Assignee: Schweitzer Engineering Laboratories, Inc.
    Inventors: Stephen F. Witt, Patricia Gilfeather, Jeff Bassett, Prajakta Apte, Anatoliy V. Kozlov

  • Patent number: 6678369
    Abstract: A signal system 7 (SS7) processing system for use in an SS7 network includes a primary interface configured to process communications according to at least one layer of the SS7 protocol stack, the primary interface being configured to provide checkpoint messages relating to the communications and the at least one layer of the SS7 protocol stack, each layer of the at least one layer of the SS7 protocol stack having a corresponding set of information associated with each communication, and a backup interface configured to process communications according to the at least one layer of the SS7 protocol stack, the backup interface being coupled to the primary interface, and configured, to receive the checkpoint messages from the primary interface, wherein the checkpoint messages contain sufficient information for the backup interface to properly process communications that are transferred from being processed by the primary interface to being processed by the backup interface and contain less than all information i
