  • Patent number: 9464917
    Abstract: A utility meter may be read by sending a request to read the meter from a meter reading application, which may be located on a utility server or on an access point to a network, to a communications module associated with the utility meter. The communications module initiates a session with the utility meter, makes requests for data from the associated utility meter, receives the responses to requests for data from the utility meter, and terminates the session after receiving all the requested data from the meter. It then formats the responses with the data received from the utility meter, and transmits the formatted response to the meter reading application.

  • Publication number: 20160285766
    Abstract: A plurality of nodes in a first network mitigate data restrictions on access points which are an interface between the first network and a second network. The access points advertise their access parameters to the second network to the nodes. The nodes maintain a list of the advertised access parameters of each access point. The nodes determine whether to transmit data to the second network according to a first transmission mode or a second transmission mode based on the data to be transmitted and the list of access parameters maintained by that node. In the first transmission mode, the node determines to transmit the data to a first access point having a lowest cost with that node. In the second transmission mode, the node determines to transmit the data to a second access point having fewer access restrictions to the second network than the first access point.

  • Patent number: 9445289
    Abstract: One embodiment of the present disclosure sets forth a technique for convergence and automatic disabling of access points in a wireless mesh network. Specifically, an access point within a wireless mesh network computes one or more network metrics to determine whether the metrics are unfavorable or favorable. If the network metrics are favorable, then the access point disables the access point's network connection. An access point turns the network connection back on based on whether a routing was lost for at least a preset amount of time, utilization of one or more neighboring access points is above a preset value, or one or more network metrics have degraded by a certain percentage value. One advantage of this approach is that cost savings may be achieved when the number of access points dynamically changes to accommodate varying communications conditions.

  • Publication number: 20160249220
    Abstract: To provide overall security to a utility management system, critical command and control messages that are issued to components of the system are explicitly approved by a secure authority. The explicit approval authenticates the requested action and authorizes the performance of the specific action indicated in a message. Key components of the utility management and control system that are associated with access control are placed in a physical bunker. With this approach, it only becomes necessary to bunker those subsystems that are responsible for approving network actions. Other management modules can remain outside the bunker, thereby avoiding the need to partition them into bunkered and non-bunkered components. Access to critical components of each of the non-bunkered subsystems is controlled through the bunkered approval system.

  • Patent number: 9377766
    Abstract: An apparatus, system, and method are disclosed for determining electrical load and lifestyle characteristics. A record receiving module receives an electrical energy usage record for premises for a predefined time period (“record period”), and receives property characteristics for the premises. The property characteristics include physical characteristics for the premises, environmental characteristics for the premises for the record period, and/or lifestyle characteristics of users of the premises. A load identification module selects a load prediction algorithm to determine if a particular type of electrical load is present at the premises. A comparison module applies the load prediction algorithm to the electrical energy usage record for the premises for at least a portion of the record period (“comparison period”) to determine if the particular type of electrical load is present at the premises. The load prediction algorithm uses the property characteristics of the premises during the comparison period.

  • Publication number: 20160165479
    Abstract: Rather than using a large number of transceivers (transmitter/receiver pairs) operating in parallel, Access Points with multiple channels are used to aggregate, or stack, transmitted response communications, e.g., transmitting multiple acknowledgements (ACKs) in a single packet to one or more sources of received packets. The method includes sending on a plurality of channels, by each of a plurality of respective first nodes, a communication to a second node, receiving on the plurality of channels, by the second node, the communication from each of the plurality of first nodes and sending, by the second node, a transmission that contains a response to each communication that was successfully received from each of the plurality of first nodes. The response to each of the plurality of first nodes is part of a single message sent by the second node.

  • Patent number: 9263915
    Abstract: The service phase of the electrical connection to a customer endpoint device located within a power distribution system is determined by various techniques. At the feeder level, the system may be programmed to induce disturbances, thereby causing missed zero crossings at the customer endpoint devices. The pattern of these disturbances is a controlled one, designed specifically to avoid causing noticeable disruption even to sensitive devices, but to be unusual enough that it is statistically unlikely to be naturally occurring. The monitoring of the zero crossing information is used to determine the phase of the service line to the customer endpoint devices.
