Patent number: 7904262Abstract: Apparatus and methodology are provided for measuring energy, particularly in a useful way for a multiphase system. Individual, like single-phase metrology blocks are provided to monitor energy in selected phases of a multiphase system. Individual data from a relatively upstream metrology block is passed to a relatively downstream metrology block, with the data stream being concatenated as the stream tracks from one metrology block to another. Energy data is coded as a predetermined small quantum of energy such that the last metrology block in a seriatim configuration of such metrology blocks may compute total energy consumption in the effective multiphase system by simple addition of the energy quantum data arriving at such last metrology block.Type: GrantFiled: June 23, 2006Date of Patent: March 8, 2011Assignee: Itron, Inc.Inventors: Andrew Lancaster, Pierre Decaux

Publication number: 20110055116Abstract: A monitoring system capable of being operationalized. Power consumption is electrical devices is monitored by the use of new and innovative consumption power monitoring device in accordance with the present invention. Power consumption information is collected by an intelligent power hub that is communicatively coupled to a remote server that presents overall power usage displays. A method of operationalizing a power usage monitoring system comprises powering up an energy pump device when the energy pump device is plugged into a first power socket, setting the energy pump device automatically to a SET mode to acquire new monitoring devices, and discovering the presence of a power consumption monitoring device.Type: ApplicationFiled: November 8, 2010Publication date: March 3, 2011Inventor: EUGENE WANG

Publication number: 20110054814Abstract: A power meter or other electrical device is provided having two independent and communicatively isolated Ethernet ports. The first Ethernet port is addressable by a first unique identifier and is configured for enabling full access to the power meter via an internal LAN. This enables a LAN operator to remotely access the power meter via the internal LAN for performing metering functions, such as full telemetry, control and programming. The second Ethernet port is addressable by a second unique identifier and is configured for being connected to the Internet. Since the second Ethernet port is communicatively isolated from the first Ethernet port, a user can access the power meter via the Internet, but cannot access the internal LAN by connecting to the power meter via the Internet.Type: ApplicationFiled: June 28, 2010Publication date: March 3, 2011Applicant: ELECTRO INDUSTRIES/GAUGE TECHInventor: Erran Kagan

Publication number: 20110046904Abstract: A system and method for analyzing a customer load and/or generation profile in order to disaggregate the customer load and/or generation profile is provided. The analysis of the customer load and/or customer generation profile may thereby determine the one or more devices that are operating and that contribute to the customer load and/or generation profile. In this way, the system and method may automatically analyze the customer load and/or generation profile in order to determine the one or more devices that contribute to the load and/or generation profile.Type: ApplicationFiled: July 30, 2010Publication date: February 24, 2011Inventor: Younes Souilmi

Publication number: 20110022845Abstract: A method for issuing a digital residence certificate using a module associated with a counter. Data from the counter are continuously monitored, whereby the data are read and a consistency test is performed on the basis of a predetermined criterion. In addition, after receiving a residence certificate request, a decision is made as to whether or not the request should be fulfilled, based on the results of the continuous data monitoring.Type: ApplicationFiled: March 27, 2009Publication date: January 27, 2011Applicant: ELECTRICITE DE FRANCEInventors: Ludovic Pietre-Cambacedes, Yves Dherbecourt

Publication number: 20110010158Abstract: Systems and methods are provided for collecting and aggregating a plurality of power flow measurements from a plurality of devices in a power management system. The error bounds of the aggregated power flow measurement are then determined using at least one error model. Systems and methods are also provided for inferring AC power flows from DC power flows. A device having at least one DC power flow sensor is augmented with at least one AC power flow sensor AC and DC power flows through the device are measured using the sensors over a range of operating points. An inference model of AC power flow in the device as a function of DC power flow is then built, wherein the error of the model is bounded. DC power flow through the device and in similar devices can then be then measured and used to infer AC power flow for the device.Type: ApplicationFiled: March 31, 2010Publication date: January 13, 2011Applicant: GridPoint, Inc.Inventor: Seth W. Bridges
