摘要： Non-flammable electrolyte compositions for lithium metal primary batteries and the cells containing these electrolytes are described. The electrolyte compositions comprise one or more partially or fully fluorinated functionalized short chain polyethers with one or more lithium salts, and may include one or more cosolvents, and may have one or more fire retardants added. Said short chain functionalized fluorinated polyethers have much better ionic conductivity than the alkyl terminated fluorinated polyethers or long chain perfluoropolyethers, which provide superior flame resistance without sacrificing overall battery performance. Heat resistant, non-flammable primary lithium cells are also disclosed.

摘要： Systems and methods for channel selection in power line communications (PLC) are described. In some embodiments, a method may include defining a plurality of frames, each frame having a plurality of time slots. The method may also include assembling a pair of beacon and bandscan packets within each of time slot of each frame. The method may further include sequentially transmitting each of the frames over a corresponding one of a plurality of different frequency bands. In some implementations, each bandscan packet may include a slot index indicating a position of its time slot within its respective frame and/or a band index indicating one of the plurality of different frequency bands. In response to having transmitted the plurality of frames, the method may include receiving one or more packets indicating a selection of one or more of the plurality of different frequency bands to be used in subsequent communications.

摘要： Systems and methods for designing, using, and/or implementing communications in beacon-enabled networks are described. In various implementations, these systems and methods may be applicable to power line communications (PLC). For example, a method may include identifying one of a plurality of orthogonal superframes. The identified superframe may include beacon slots and contention access period (CAP) slots. The beacon slots may follow a sequence of two or more frequency subbands, and the CAP slots may follow the same sequence of two or more frequency subbands. Also, the sequence of two or more frequency subbands may be distinct from other sequences of two or more frequency subbands followed by other beacon slots and CAP slots within others of the plurality of available superframes. The method may then include communicating with another device using the identified superframe.

摘要： A method of performing dynamic sounding in a wireless communication device includes determining whether to perform sounding based on an age of current channel state information (CSI). An achievable throughput can be recorded as a reference throughput after performing the sounding. A current achievable throughput can be compared with the reference throughput. A CSI timestamp can be reset when the current throughput is above the reference throughput by a first predetermined amount, thereby prolonging a lifespan of the current CSI. The CSI timestamp can be reduced when the current throughput is below the reference throughput by a second predetermined amount, thereby reducing the lifespan of the current CSI.

摘要： Systems and methods for a media access control (MAC) layer for power line communications (PLC) are described. In some embodiments, a method may include receiving packets for transmission, each packet associated with a priority code, each priority code unrelated to its corresponding packet's time or order of arrival. The method may also include transmitting a first subset of packets having priority codes higher than priority codes in a second subset, and buffering the packets in the second subset for later transmission. Another method may include identifying a link quality indicator (LQI) associated neighboring service nodes, selecting one of the service nodes with highest LQI, and transmitting a promotion needed packet data unit to the selected service node. Yet another method may include communicating an Internet protocol (IP)-based message to a PLC device that excludes mesh header information, fragmentation header information, and/or the IP address of the PLC device.

摘要： A system and method for reducing transmission collisions. In one embodiment, a transmitter for communicating of a smart grid power line network includes an arbiter. The arbiter is configured to select a transmission interval during which the transmitter can transmit. The interval is selected from a plurality of available transmission intervals reserved for contending transmissions, and selected based on a level of a hierarchical network at which the transmitter is located. The interval selected is different from any interval used by a different transmitter spaced two hierarchical levels away from the level of the hierarchical network at which the transmitter is located.
