A method, apparatus, and system for disconnecting loads from the electrical grid based on a power line frequency are disclosed. An electricity meter may monitor a power line frequency of a source power line connected to the electricity meter, and in response to determining that the power line frequency is lower than a disconnect threshold frequency, may open an internal switch and disconnect a load side output of the electricity meter from the source power line.

Frequency-based distributed load disconnect

In an electrical grid, several electricity meters may be associated with the same transformer, and may measure electricity sold to respective customers. In an example, one electricity meter executes manager software, while the other electricity meters execute agent software. One or more applications operated on each electricity meter, and control metrology devices, data processing, operation of radio(s) and/or a powerline communications modem, aspects of electrical phase determination, etc. The agent software operating on each electricity meter may relay messages from applications operating on that electricity meter to other (possibly similar) applications operating on other electricity meters. Each message sent by each instantiation of agent software may include a networking score of that electricity meter. The manager software may additionally communicate with a data collector and/or main office server(s). The manager software may select a replacement meter from among those connected to the same transformer to assume the role of executing manager software.

Efficient collaboration between meters under the same transformer

A data collection device and method for determining an alternative event condition is presented. The method includes receiving a first data communication including a first data value from a first sensor and determining a first event condition based on the first data value being beyond a predetermined threshold. The method further includes receiving additional data communications including additional data values from one or more second sensors, aggregating the first data value and the additional data values, and determining that the determination of the first event condition is incorrect based on the aggregated data values and a known relationship between the first sensor and the one or more second sensors. The method additionally includes determining a second event condition based on the first data value and the additional data values being beyond the predetermined threshold. An action may then be performed in response to the determination of the second event condition.

Determining alternative outcome or event based on aggregated data

A data collection device and method for determining a backflow condition in a water distribution system. The data collection device receives a first data communication from a first node, the first data communication indicating a first possible backflow condition at the first node. The data collection device receives additional data communications from one or more second nodes, the additional data communications indicating backflow conditions at the second nodes. The data collection device aggregates and analyzes the first data value and the additional data values and determines that an actual backflow condition exists based on the aggregated data values and a known relationship between the first node and the second nodes. The data collection device may then perform action(s) in response to determining the backflow condition, such as reporting the backflow condition, requesting updated reporting from the nodes, closing appropriate valves, initiating pumps to increase water pressure, flushing the system, etc.

Techniques for efficient compression of sensor data are described herein. In an example, metrology data is received from a metrology device, the metrology data comprising one or more of: voltage (V) data; current (A) data; resistive power (W) data; and volt-amps reactive power (VAR) data. The metrology data is processed, wherein the processing comprises: performing peak-detection on the metrology data, to create data-signals comprising: a timestamped peak-values data-signal; and a peak-removed data-signal. Median-filtering is performed on the peak-removed data-signal, wherein a median-filtered data-signal is created. Level-shift detection is performed on the median-filtered data-signal, wherein a timestamped level-shift data-signal is created. The data is sent to a server. The data may include the timestamped peak-values data-signal and the timestamped level-shift data-signal.

Methods for barging an online user on a real-time communications network are presenting including: making a barge request by a barging user to barge online users; if online users are a part of an on-going call and the barging user has a barge privilege, joining the barging user with the on-going call; and if online users are not part of the on-going call and the barging user has the barge privilege, creating a new call with the barging user and the online user. In some embodiments, methods further include: if the barging caller is restricted and the barging user does not have the barge privilege, denying the barging user from the joining; and if the barging caller is not restricted and the barging user does not have the barge privilege, joining the barging user with the on-going call, and granting the floor control based on a standard floor control rule.

Methods for integrating an application on a user equipment (UE) utilizing a special URI (S-URI) control message over a communications network are presented including: registering a secondary application server on the communications network such that a primary application server responsive to the UE is notified of the secondary application server, wherein the secondary application server is configured to provide the application; selecting the application on the UE; sending an INVITE message containing the S-URI to the primary application server by the UE, the S-URI configured to provide access information corresponding with the secondary application server; locating the secondary application server by the communications network; establishing a session between the secondary application server and the UE, wherein the application is provided to the UE by the secondary application server.
