Abstract:
Disclosed are methodology and corresponding apparatus subject matters for providing improved efficiency in the collection of data from a large number of metrology devices associated with an Automated Meter reading (AMR) network. AMR network operation produces randomly spaced transmissions from individual nodes in the network. When an AMR system wishes to retrieve data from a large number of points over an AMR network, a broadcast or multicast request is transmitted to appropriate nodes. A time window is defined either in such request or in the devices themselves such that start and end offsets from the time of the request are received by the node. The start offset provides a quiet period to insure request delivery to all the appropriate nodes. The end offset provides a time by which the requested data must be returned. Responses are sent randomly within the window established by the start and stop offset times.

Abstract:
Disclosed are handheld or portable apparatus subject matters and associated methodologies for providing local communications to metrology devices within an Advanced Metering System (AMS). The metrology devices may be associated with AC supplied device that are configured with mailboxes for associated battery powered devices or with other home or customer premises area network devices. Battery powered metrology devices may include such as water, gas, and oil meters collocated with electricity meters. Communications between the handheld or portable device may be by way of direct wired or radio frequency connections for providing communications and diagnostic services for home area network coupled components in an Advanced Metering System.

Generally described, the disclosed subject matter is directed to improved processes for securely accessing a meter. In accordance with one embodiment, a method for providing a mobile meter reader with an authorization that may be used to establish a secure session with a meter is implemented. In particular, the method includes issuing a request for authorization to access the meter from the mobile meter reader. If the mobile meter reader maintains sufficient rights, an authorization having an encoded digital signature is generated at a host computer system and provided to the mobile meter reader. Then the method formulates and transmits an authorization command to the meter having the encoded digital signature that was generated by the host computing system.

International Classification:
H04W 36/16 H04W 84/12
US Classification:
370230
Abstract:
A new device is deployed to an area in which a network is provided. The new device may join the network using a single handshake via a neighboring device that is a member of the network and register with a network management system managing the network. If the network is overloaded or has limited bandwidth remaining, the network may refuse to admit the new device, or if the new device is isolated, may force some devices that are members of the network to leave or migrate from the network to allow the isolated device to join the network.

International Classification:
H02J 3/36
Abstract:
A control module controls impedance injection units (IIUs) to form multiple connection configurations in sequence. Each connection configuration has one IIU, or multiple IIUs in series, parallel or combination of series and parallel. The connection configurations of IIUs are coupled to a high-voltage transmission line. The control module and the IIUs generate rectangular impedance injection waveforms. When the waveforms are combined and injected to the high-voltage transmission line, this produces a pseudo-sinusoidal waveform.

Abstract:
In prior art grid systems, power-line control is done by substation based large systems that use high-voltage (HV) circuits to get injectable impedance waveforms that can create oscillations on the HV power lines. Intelligent impedance injection modules (IIMs) are currently being proposed for interactive power line control and line balancing. These IIMs distributed over the high-voltage lines or installed on mobile platforms and connected to the HV power lines locally generate and inject waveforms in an intelligent fashion to provide interactive response capability to commands from utility for power line control. These IIMs typically comprise a plurality of impedance-injection units (IIUs) that are transformer-less flexible alternating current transmission systems interconnected in a series-parallel connection and output pulses that are additive and time synchronized to generate appropriate waveforms that when injected into HV transmission lines are able to accomplish the desired response and provide interactive power flow control.
