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.

Bandwidth management in a powerline network

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.

Flexible scheduling of resources in a noisy environment

A method and system for assessing the health status of a patient, such as the asthma status of a patient, provides an asthma status score and a confidence rating indicative of the score's reliability using continuous real-time data. In some embodiments, the assessment comprises a multidimensional analysis in which asthma status scores and respective confidence ratings are generated for multiple individual asthma health dimensions as well as a summary asthma health dimension indicative of overall asthma health. In some embodiments, the individual dimensions include an environmental trigger dimension based on sensor-based environmental data, a physiological burden dimension based on sensor-based physiological data, a medication adherence dimension based on patient diary data and a perceived symptom dimension based on patient diary data.

Asthma status scoring method and system with confidence ratings

A method of determining a transmission process is disclosed. One embodiment comprises a method of notifying a central coordinator of a group to receive a transmission and obtaining system parameters from the central coordinator. The method then determine at least one merit parameter using at least one of the system parameters and at least one local parameter and selects a method of transmission based upon the merit parameter.

Systems and methods for network channel characteristic measurement and network management

Methods and systems for particle characterization using a light fluctuation component of an optical sensor output signal. The use of the light fluctuation component enables particle characterization (e.g. provision of information on particle size, type and confidence) without requiring measurements at multiple wavelengths or multiple angles and using relatively lightweight calculations. The methods and systems allow integration of real-time airborne particle characterization into portable monitors. The methods and systems in some embodiments also use the output signal to further characterize particles through determination of particle density information.

Aspects of the present invention relate to methods and systems for managing and allocating bandwidth in a communication medium. Some aspects relate to the determination of bit usage patterns for use in allocating bandwidth. Some aspects relate to the further determination of a derived usage pattern from the bit usage patterns and allocation of tone-slots within the derived usage pattern.

Embodiments of the present invention comprise systems and methods for network connection setup and bandwidth allocation comprising negotiable and non-negotiable modulation allocation procedures.

Systems and methods for network channel allocation

A method of transmitting data is disclosed. The method transmits data from a source device over a contention channel in a centralized network to more than one device on the channel, including a central coordinator. The method then waits for a data acknowledgment signal from the central coordinator as an indicator of successful reception of the data by any device to which the data was transmitted.

Transmitting data across a contention channel in a centralized network

The embodiments of the present invention provide methods, devices, and systems that automatically provide quality of service to one or more packets, typically by determining whether packets are connection-worthy and accordingly providing connection specifications.

Method for automatically providing quality of service

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.

Convergence and classification of data packets in a centralized communication system

The embodiments of the present invention provide methods, devices, and systems enabling a central coordinator to manage hidden stations via a proxy central coordinator, where a hidden station is discovered based on beacons and made known to other networked devices via transmitted lists.
