摘要:
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.

Disclosed are apparatus and methodology subject matters for providing communications to battery powered metrology devices within an Advanced Metering System (AMS). The battery powered metrology devices may be associated with AC supplied devices that are configured with mailboxes for their associated battery powered devices. The battery powered metrology devices may include such as water and gas meters collocated with electricity meters. Communications between the battery powered devices and their associated mailbox containing electricity meters may be by way of direct wired or radio frequency connections for providing reliable message transport between communications system coupled components in an Advanced Metering System.

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.
摘要:
An automatic meter reading (AMR) system utilizes versatile radio packets that are recognizable by AMR system receivers capable of receiving conventional interval data message (IDM) radio packets. A versatile radio packet includes a packet preamble portion, a packet body portion, and a packet validation portion. The packet preamble portion has a frame synchronization bit sequence that is recognizable by existing or conventional encoder-receiver-transmitter (ERT)-compatible AMR system receivers, such as a bit sequence equal to 0x16A3. The packet preamble portion also has a packet type identifier field and a packet length field. The packet body portion includes at least an endpoint serial number field and a message, where at least the message has a variable length. Optionally, the message includes a message type identifier field and a message value field that can have a plurality of sub-fields. The AMR system may use message type identifiers optionally present in the versatile radio packets to filter, or discriminate between, certain message types at the reader level. Versatile radio packets can enable endpoints and other devices in the AMR system to transmit a variety of new information to existing AMR infrastructure without having to conduct a significant infrastructure overhaul of the AMR system.

摘要:
A fluid flow impedance system including a member having a wall with at least one opening therethrough and a tool positionable relative to the at least one opening. The tool has a carrier with an expandable material disposed therewith. The expandable material is operatively arranged to expand into the at least one opening, in response to the expandable material experiencing a predetermined condition, for impeding a flow of fluid through the at least one opening.
