AUTONOMOUS TOPOLOGY VALIDATION FOR ELECTRICAL SUPPLY NETWORK
A system for autonomously validating the topology information of an electrical power distribution system is provided. For example, the system includes a group of meters previously determined to be connected to the same transformer of an electrical power distribution system. The group of meters is configured to perform family check periodically or upon request and to identify orphan meters in the group. The identified orphan meter can contact a community device communicatively connected to meters in more than one group to request a community check. The community device performs the community check by contacting meters in other groups of meters and obtain their family signature data. The community device further determines whether the orphan meter belongs to a new family based on the voltage data of the orphan meter and the family signature data of other groups. The orphan meter can report the community check results to a headend system.

Provisioning platform for machine-to-machine devices
Techniques described herein include a platform and process for provisioning user information onto a machine-to-machine device in order to enable the machine-to-machine device to conduct transactions utilizing the user information. In some embodiments, a user device is used to relay information between a machine-to-machine device and a provisioning service provider computer. In some embodiments, a machine-to-machine device is connected to the provisioning service provider computer via a network connection. Upon receiving a request to provision the machine-to-machine device, the service provider computer may identify the device from a device identifier. The service provider computer may generate an access credential or token for the machine-to-machine device. The access credential, token, and/or one or more policies may be provisioned onto the machine-to-machine device.
Portable Fuel Metering System
A portable fuel metering system (PMU) is described. The PMU has one or more flow meters capable of metering the flow of fluids, such as fuel, as the fluid is transferred from a source to a receiver. The PMU may include a telemetry unit configured to transmit parameters related to the fuel transfer to remote location. The PMU may be configured in a light, portable package that may be carried by one or two people. The PMU may include a power generator that is configured to use the flow of fluid to the PMU to generate power for the PMU's operation.
Devices having communication circuitry decoupled from device circuitry and related meters and housings
A meter assembly is provided including a register or an index associated with a meter; and a communication circuit decoupled from the register or the index and configured to communicate with the register or the index using an optical communication link between the register or the index and the communication circuit. Related communication circuit housings are provided.
Method and system to detect non-technical losses in an electrical power system
A method for detecting non-technical losses in an electrical power system includes measuring an area under a squared RMS current curve for a power cable in the electrical power system over at least one time interval, measuring an active and a reactive energy for the power cable over the at least one time interval, and characterizing a cable reactance and a cable resistance using the active energy, the reactive energy, and the area under the squared RMS current curve. The method further includes determining an active energy loss and a reactive energy loss over the at least one time interval using the area under the squared RMS current curve and the reactance and the resistance of the cable, and detecting a non-technical loss in the electrical power system based on the active energy loss and the reactive energy loss over the at least one time interval.

An infrastructure monitoring assembly includes a nozzle cap defining a first end and a second end, the first end defining a threaded bore configured to mount on a nozzle of a fire hydrant; a cover coupled to the nozzle cap opposite from the first end; an enclosure positioned at least partially between the cover and the first end, the enclosure at least partially defining a cavity; a monitoring device positioned within the cavity; and an antenna positioned between the cover and the first end of the nozzle cap, the antenna connected in electrical communication with the monitoring device, the antenna covered by a non-metallic material.
Method for reading meters for fluids
A system, referred to as a reading system, used in an automated metering management system in the context of a fluid-distribution service comprising a plurality of fluid meters is disclosed. The first communication module in accordance with a wireless communication standard is used by each fluid meter and a second communication module suitable for communicating by powerline with a data concentrator via a first network, said data concentrator communicating with a management entity of the automated metering management system via a second network. Instancing an application emulating a virtual fluid meter able to communicate directly with the data concentrator for each fluid meter in the plurality, and, for each fluid meter in the plurality, the corresponding virtual fluid meter takes responsibility for retransmitting information representing a fluid-consumption reading, said information having been supplied to the reading system by said fluid meter to the management entity via the data concentrator.
LOW POWER SENSOR NETWORK
Device power consumption is reduced by operating using both one-way and two-way communication techniques. In an aspect a device operates in a first mode enabling one-way communication to an other device for a first portion of device operation time. The first mode includes transmitting a first set of messages to the other device while turning off a power supply used by a receiver of the device. The device switches between operating in the first mode and the second mode. The second mode enables two-way communication between the device and the other device for a second portion of device operation time less than the first portion of device operation. The second mode includes transmitting a second message to the other device, and in response to the transmitting the second message, turning on the power supply used by the receiver.
METHOD AND APPARATUS FOR MONITORING CONSUMPTION OF FLOWING SUBSTANCE
An apparatus for monitoring consumption of flowing substance is provided. The apparatus, connectable to the end of a pipe where fluid is flowing, includes a generator (106) configured to generate electric power from the fluid passing through the generator, sensors (112, 114) to measure the temperature of the fluid and the amount of fluid flowing in the pipe and a processing unit (116). The apparatus detects that fluid starts flowing in the pipe at a first time instant and detects that fluid stops flowing in the pipe at a second time instant and determines the temperature of the fluid and the amount of fluid that flowed through the pipe between the first and the second time instant, stores the determined values and the time elapsed between the first and the second time instants as an entry in a memory (120); and transmits the entry.
