  • Patent number: 8327045
    Abstract: A system and method stores wirelessly received communications for wireless retransmission, making space in a storage device, if necessary, by deleting any one or more communications corresponding to the same group as the received communication. If storage in the storage device remains insufficient, communications that have been previously retransmitted by that same device are deleted, according to one or more characteristics of such stored communications, such as age or number of times an instance of that communication has been received. If storage in the storage device remains insufficient, communications of a different group are deleted according to one or more characteristics of the stored communications.

  • Publication number: 20120276839
    Abstract: A system and method communicates commands from a command originator to receiving devices, yet the receiving devices do not confirm receipt of the command. The most current command (e.g. the one with the highest sequence number) is rebroadcast by the command originator and the receiving devices, tending to be more frequent upon detection of an event indicating that the most current command was not received by at least one other device, and less frequently upon detection of an event indicating that the most current command was provided with sufficient duplication that if another device could receive it, the device likely did receive it, subject to a maximum and minimum rate.

  • Patent number: 8150792
    Abstract: A system and method applies events to a set of rules, and such rules can produce still other events that can be provided to the same or different set of rules. Rules may have attributes, and all rules or only those with attributes corresponding to an object may be stored for use with a device that has been added to, or is part of, the device.

  • Patent number: 8130001
    Abstract: A system and method monitors indicators including other-than-current indicators of protective devices such as cutouts and reclosers, to determine whether the protective devices are restricting, below their rated capacity, or interrupting, current they carry. The system and method dispatches a technician to such device.

  • Patent number: 5241635
    Abstract: A data flow processing system has a plurality of processing elements and memory units. Communication amongst processing elements and amongst processing elements and memory units is facilitated by an interconnection network. Each processing element is pipelined. The system operates upon data objects known as tokens. The tokens initiate activity within the processing element pipelines. Included within the activities initiated by the tokens is execution of instructions. Operands for instructions are matched in non-associative portions of memory known as activation frames. The activation frame memory locations have a state field that indicates whether a value is present or not in the activation frame. The state field may also indicate other information about an activation frame memory location. The state field is used to determine what action is taken at an activation frame memory location when an instruction is executed. The state field also determines the scheduling of execution of instructions.
