摘要:
There is provided a powerline network that includes a number of stations including a central coordinator for coordinating transmissions of each of the stations. Each of the stations is configurable to generate one or more tone maps for communicating with each of the other stations in the powerline network. Each tone map includes a set of tones to be used on a communication link between two of the stations. Each tone map further includes a unique set of modulation methods for each tone. Each of the stations is further configurable to generate a default tone map for communicating with each of the other stations, where the default tone map is valid for all portions of a powerline cycle. Each of the stations is further configurable to monitor its bandwidth needs and to request additional bandwidth from the central coordinator.

There is provided a powerline network that includes a number of stations including a central coordinator for coordinating transmissions of each of the stations. The central coordinator is configurable to transmit a beacon at an interval based on a phase of a powerline cycle. The interval of the beacon can be substantially equal to two periods of the powerline cycle. The interval of the beacon includes a reserved region including a persistent allocation region and a non-persistent allocation region. The beacon also includes a broadcast message including a persistent schedule and a non-persistent schedule. The persistent schedule is valid for a current beacon period and a number of subsequent beacon periods as indicated by the beacon, while the non-persistent schedule is valid for a single beacon period. The persistent allocation region and the non-persistent allocation region are determined based on the persistent schedule and the non-persistent schedule, respectively.

A system for staging a mobile device is described. The system includes a storage device for storing a staging profile of a mobile device. A cradle is coupled to the storage device. The cradle includes at least one cradle port adapted to connect to the mobile device. The cradle receives the staging profile from the storage device and transmits the staging profile to the mobile device for application thereon.

A personal environmental monitoring method and system and a portable monitor for use therein permit real-time mobile monitoring of environmental conditions in the immediate vicinity to ensure compatibility with the particular environmental sensitivities of a person being monitored. The portable monitor may be a fully integrated mobile device that provides real-time mobile monitoring of immediate environmental conditions without network connectivity.

A method of converting application data to transport data in a power line communication system includes receiving application data from an application in a device through a service access point. The connection type and connection specification for the application data is then analyzed to determine if a connection exists for the application data. If a connection exists for the application data, mapping the application data is mapped into transport data.
摘要:
A method and system classify respiratory phases in a single channel acoustic signal as inspiratory and expiratory using explicit labeling with label verification. In the method and system, a subject explicitly indicates through a user input the start of a respiratory cycle (i.e. start of inspiration). The phase indication is applied to provisionally label several consecutive phases of a single channel acoustic signal as inspiratory and expiratory. A provisional phase rule set is then generated based on characteristic differences between the inspiratory and expiratory phases. The phase indication, provisional labeling and provisional rule set generation steps are then repeated. The two generated provisional rule sets are then compared for a match to verify the accuracy of the subject's phase indications and the ability to automatically recover phase in the event of signal loss.

摘要:
A method and corresponding system for communicating between stations in a network are presented. The method includes providing repeated beacon transmissions from a coordinator station for coordinating transmissions among a plurality of the stations; transmitting from a first station to a second station during a time slot assigned to the first station by at least one of the beacon transmissions; and transmitting from the first station information that grants permission to the second station to transmit during at least a portion of a time slot assigned to the first station.
