    摘要: A data communications network, for which presence information is maintained for wireless data communication devices forming nodes of the network, includes: a presence server; and a plurality of nodes formed by the wireless data communication devices, each of the devices configured to send periodic check-in messages to the presence server. The presence server is configured to send an acknowledgment in response to a check-in message. Each of the wireless data communication devices is configured to reset a timer associated with the sending of the check-in messages by it upon (i) communicating, as an intermediate node, a check-in message originating at another node, and (ii) communicating, as an intermediate node, a corresponding acknowledgment originating at the presence server. The presence server is configured to update presence information of wireless data communication device from which a check-in message originates and each intermediate node.

    摘要: A method and apparatus for attenuating an interfering signal corrupting a desired Loran C signal is provided. An interfering signal sample is determined which occurs at the peak of the autocorrelation function of the interfering signal such that the period of the interferer is known. The sample occurring at the peak of the autocorrelation function is added to or subtracted from the desired Loran C signal sample taken at a predetermined reference point during the pulses thereof such that the interfering signal is cancelled or substantially attenuated.

    摘要: A data communication network includes two logically distinct class-based networks conjoined by at least one common node that has membership in each of the respective classes of the two logically distinct class-based networks. Optionally, three or more class-based networks may be conjoined to form a data communications network.

    摘要: An intersystem communication path (20, 67) can be established on an as needed basis. Already established paths are fully utilized before new paths are established. Already established paths can be automatically disconnected when no longer needed, or when existing calls can be merged on to fewer lines. Dial up lines can be mixed with dedicated lines. If desired, excess capacity can be guaranteed to accommodate high traffic conditions and/or other conditions that precipitate a likely need for communication services between systems.
