A docking station advantageously provides a location identifier to a portable processing device which processes the location identifier to determine docking station location (and other information) and to upload settings and configuration information related to an identified location which is retained until a different docking station location is encountered. In a system for use in a docking station suitable for attaching to a portable patient monitoring device for processing signal parameters acquired from a patient, a power coupler couples power to provide electrical power to a portable processing device. An adaptive communication interface, in a first mode of operation, communicates an identifier associated with a particular docking station to the portable processing device, and in a second mode of operation, establishes connection of the portable processing device to a network.

An exemplary wireless communication network that includes a base that communicates with remote units located in a cell of the network. A base concatenates information symbols with a preamble corresponding to a destination remote unit. One or more remote units communicating with a base each concatenates information symbols with a preamble corresponding to that remote unit. An adaptive receiver system for a base unit rapidly adapts optimal despreading weights for reproducing information symbols transmitted from multiple remote units. A transmitter system for a base unit concatenates information symbols with a preamble associated with a remote unit in the cell. An adaptive receiver system for a remote unit in a communication network rapidly adapts optimal weights for reproducing a signal transmitted to it by a specific base unit in the network. A transmitter system for a remote unit in a cell of a communication network which concatenates information symbols with preamble associated with the remote unit. A base initiates communication with a desired remote unit by transmitting an initiation codeword in a selected entry slot. One or more remote units each initiates communication with a base by transmitting an initiation codeword associated with the remote unit in a selected entry slot. A remote unit synchronizes in time and frequency to the base using a sequence of synchronization signals transmitted by the base in a number of entry slots.

A communication protocol that provides link-level and media access control (MAC) level functions for wireless (e.g., ad-hoc) networks and is robust to mobility or other dynamics, and for scaling to dense networks. In a mobile or otherwise dynamic network, any control-packet collisions will be only temporary and fair. In a dense network, the network performance degrades gracefully, ensuring that only a certain percentage of the common channel is consumed with control packets. The integrated protocol allows packets (e.g., data scheduling control packets) to be scheduled in a collision-free and predictable manner (known to all neighbors), multicast packets can be reliably scheduled, as well as streams of delay- or delay-jitter-sensitive traffic. Further, using an optional network code, the scheduling of control packets can appear to observers to be randomized.

Systems, method, and devices are provided for transmitting data. In one aspect, a method includes providing a plurality of communication modules, each of the plurality of communication modules configured to transmit data using a different communication method; establishing, with the plurality of communication modules, a plurality of simultaneous respective communication links to a remote terminal; selecting, based on a switching criterion, at least one of the plurality of simultaneous respective communication links to be used to transmit data; and transmitting data via said at least one of the plurality of simultaneous respective communication links selected based on the switching criterion.

System and method for the adaptive control of VHF communications in aircraft. In one embodiment, the invention includes an adaptive communications system for an aircraft having a communications processor that accesses a communications switching model to select a preferred ground communications station. In another embodiment, a method of communication between an aircraft and a ground station includes receiving a communications switching model and determining a flight parameter for the aircraft as the aircraft navigates along a flight route and selecting a ground station based upon the determined flight parameter. The aircraft then communicates with the selected ground station. In still another embodiment, a method for compiling a communications switching model includes receiving signals from a ground station and measuring a signal strength. A preferred ground station is selected based upon the measured signal strength value.

One embodiment relates to a method for transitioning from an initial data rate utilizing an initial transmission variable to a new data rate in a multi-carrier communication system. In the method, a first function or a second function is selected to calculate a modified transmission variable, wherein the first function or second function is selected as a function of relative priorities of first and second communication parameters. The new data rate is implemented by modification of transmission variable. Other methods and systems are also disclosed.
