  • Patent number: 8588410
    Abstract: Nodes of a network are each provided with a seed value and a seed identifier. Each seed value has a corresponding unique seed identifier which is maintained within the system. Within each authorized node, the seed value is combined with a local node identifier, such as a serial number or other unique identifier, to form a cryptographic key that is then used by the node to encrypt and/or decrypt data transmitted and received by that node. The cryptographic key is never transmitted over the network, and each node is able to create a different cryptographic key for use in communicating with other nodes.

  • Patent number: 8477794
    Abstract: Techniques for using an Advanced Metering Infrastructure (AMI) system for Utility Automation (UA) purposes in a utility distribution system are disclosed herein. In an AMI system, a metering node often includes a communications option board for connecting to a wide area network (WAN), which can be shared between the AMI system and a UA system. The metering node may be near other devices that can be controlled by a utility company to monitor and control components of the utility distribution system. A data packet is received in a communication device. The communication device determines whether the received data packet is formatted according to a first protocol employed by the AMI system. If so, then the data packet is forwarded to a first device in communication with the AMI system. If not, then the data packet is forwarded to a second device in communication with the UA system.

  • Patent number: 8379355
    Abstract: A method of detecting the presence of an unsafe line condition at a power metering device is disclosed. The method comprises the steps of determining if a disconnect switch is in the open position, and measuring a first voltage at a first load contact. The method measures a second voltage at a second load contact and determines if the first voltage is greater than a first voltage threshold or less than a second voltage threshold. The method further determines if the second voltage is greater than the first voltage threshold or less than the second voltage threshold. The method indicates that an unsafe condition exists if either the first voltage is greater than the first voltage threshold, or first voltage is less than the second voltage threshold or the second voltage is greater than the first voltage threshold or the second voltage is less than the second voltage threshold, when the disconnect switch is in the open position.

  • Patent number: 8320302
    Abstract: Techniques for over the air (OTA) microcontroller flash memory updates using a wireless network are disclosed herein. A control node first transmits the microcontroller flash memory update to all devices that can receive the message. Each packet of the message is relayed through multiple communication levels until all devices receive the packet. This starts with communications from the control node to each device node that has a direct communication path to the control node, which are referred to herein as “first level” device nodes. The first level device nodes then relay each communication to each other device node that has a direct communication path to the first level device nodes, which are referred to herein as “second level” device nodes. This process is repeated at each level of the wireless network until each of the plurality of device nodes has received the microcontroller flash memory update.

  • Patent number: 8279778
    Abstract: A wireless mesh network, method of operating a wireless mesh network, and a central node device are disclosed herein. Communications are interleaved to maintain a spatial differential, for example, two “hops,” between any two nodes transmitting in proximity to the collector. In one embodiment, a wireless mesh network includes a central node and a plurality of bidirectional nodes in bidirectional wireless communication with the central node. Each bidirectional node has a respective wireless communication path to the central node that is either a direct path or an indirect path through one or more intermediate bidirectional nodes. Each bidirectional node is characterized by a number of intermediate bidirectional nodes forming a respective wireless communication path to the central node. The central node isolates a first data communication from a first node from second data communications from other nodes that are within a defined threshold of hop levels of the first node.

  • Patent number: 8248972
    Abstract: A method, wireless mesh network and processor-readable storage medium for promoting successful end-to-end communication in a polled mesh network while improving system throughput are disclosed herein. Successful communications are acknowledged at each hop level to reduce the need to duplicate packets for redundancy. In this way, if a first bidirectional node transmits a packet to a second bidirectional node, the second bidirectional node acknowledges the packet, and the first bidirectional node receives the acknowledgement, then the first bidirectional node does not need to send a duplicate packet.

  • Patent number: 8242931
    Abstract: A method, collection device, and automatic meter reading (AMR) system for locating stolen utility meters use a set of identifiers, such as transponder serial numbers, to build a route of utility meters that have been reported as having been stolen. When each mobile collection device's daily routes are prepared, the route of stolen utility meters is added to the other routes for which the mobile collection device is ordinarily tasked with collecting meter read data. As the mobile collection device traverses its daily routes, it collects meter read data for the stolen utility meters along with the meter read data for its other routes. The route of stolen utility meters is unloaded from the mobile collection device along with the other daily routes when the read process is finished. The route of stolen utility meters may contain information that may assist the utility company in locating the stolen utility meters.

  • Patent number: 8073384
    Abstract: Techniques for optimization of redundancy and throughput in an automated meter data collection system using a wireless network are disclosed herein. The wireless network comprises a central node, a plurality of bi-directional nodes, and a plurality of transmit-only meters. Each of the bi-directional nodes is in bi-directional wireless communication with the central node and has a wireless communication path to the central node that is either a direct path or an indirect path through one or more intermediate bi-directional nodes serving as relay nodes. The transmit-only meters wirelessly transmit meter data that is then relayed by one or more bi-directional nodes to the central node. Each of the bi-directional nodes is assigned one or more authorized transmit-only meters, and each of the bi-directional nodes is configured to relay meter data only from its authorized transmit-only meters, thereby providing an optimum level of redundancy and throughput in the network.

  • Publication number: 20110158160
    Abstract: Various methods of operating a wireless mesh network are disclosed herein. According to various embodiments, an Internet Protocol (IP) router generates IP addresses for wireless sensor nodes that do not have native support for the IP protocol stack. The IP router then receives and translates an incoming IP request and routes the incoming IP request to the appropriate wireless sensor node. In some embodiments, an IP data packet can be encapsulated and routed using an IP router and an IP bridge device. In other embodiments, an Internet Control Message Protocol (ICMP) session can be managed over a wireless mesh network.
