| 20120112901 | Systems for Detecting, Collecting, Communicating, and Using Information About Environmental Conditions and Occurrences - Systems and methods are disclosed for identifying and providing warnings of tornadoes, hurricanes, earthquakes, and other environmental occurrences. Temperature, pressure, seismic activities and other environmental conditions are measured with improved granularity using sensors at multiple locations. More extensive distribution of sensors is enabled using existing networks, such as utility (e.g., gas and electricity) meter networks. Network traffic is improved by screening information locally so that only limited information is sent for central processing. A given location, for example, may compare its own and its neighbors measurements against a profile to identify the probable existence of a tornado before sending a message to a central processing device. Upon receiving such a message and possibly other information (e.g., other messages or weather service information), a central device may send notifications to specific facilities that an environmental occurrence may be occurring, for example, notifying specific residences in the expected path of a tornado. | 05-10-2012 |
| 20120078548 | Utility Device Management - Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for managing utility device operations. In one aspect, a utility apparatus includes a processing apparatus that manages data processing tasks for the utility apparatus. The utility apparatus also includes a communications apparatus, coupled to the processing apparatus, that is configured to transmit and receive data over a network. A metrology apparatus is coupled to the processing apparatus, the metrology apparatus being configured to measure and provide meter data that includes at least a measure of utilized utility services. A network apparatus is also coupled to the processing apparatus, the network apparatus being configured to coordinate communication between devices that belong to a home area network. A utility identification module interface is coupled to the processing apparatus, the utility identification module having an interface that removably receives a utility identification module. | 03-29-2012 |
| 20120025979 | METHODS AND SYSTEMS FOR SENDING MESSAGES REGARDING AN EMERGENCY THAT OCCURRED AT A FACILITY - Systems and methods are disclosed for sending messages regarding an emergency at a facility. The messages can be sent to an emergency response service or directly to another facility through a wireless mesh network. The wireless mesh network can comprise one or more nodes that route measurement data, such as utility meter reading data. The emergency messages can be assigned a higher priority so that they travel through the wireless mesh network more quickly. A device receiving an emergency message may identify the address of the associated facility, for example, by identifying an address associated with utility service also provided at the same facility. The address can be forwarded to an emergency response service and a confirmation or other message may be sent back to the facility. A device at a facility may receive various messages from a control center, such as a weather center, over the wireless mesh network. | 02-02-2012 |
| 20110291660 | System and Method for Low Battery Detection - Systems and methods for monitoring a voltage pump to determine the status of a battery connected to the voltage pump are provided. The operation of the voltage pump is monitored during at least one monitoring period which corresponds to a period of relatively heavy consistent load. The operation of the voltage pump can be monitored by sampling a control signal that corresponds to the operation of the voltage pump. | 12-01-2011 |
| 20110164531 | Systems and Methods for Wireless Network Routing Using Radio Frequency Distance-Based Virtual Node Locations - Devices and methods used in a wireless network employing geographical routing using virtual node locations. Such virtual node locations can be computed by a central computer that gathers information from some or all of the nodes. Each node may, for example, identify itself and its neighbors and provide a value indicative of the radio frequency (RF) distance to such neighbors. Examples of RF distance indicators include, but are not limited to, received signal strength indication (RSSI) and packet success rate (PSR). Geographic coordinates for none or some of the nodes may also be used to determine the virtual coordinates. | 07-07-2011 |
| 20110075704 | Methods and Systems for Distributing Broadcast Messages on Various Networks - Methods and systems for sending a broadcast message in frequency hopping and other systems. Instead of sending a complete message separately to each device, a relatively small packet or “chirp” is sent. These chirps are either targeted at known devices or sent in a manner to sweep the RF band. Devices that hear the chirps get information about the channel and/or time that the broadcast data will be sent. These devices then listen for the broadcast data as instructed, e.g., at the specified time on the specified channel. A system may alternatively, or in addition, use a scheduled hopping sequence break as a broadcast moment. Such a broadcast moment can be scheduled to periodically interrupt the node hopping sequences so that, at such times, many or all nodes are scheduled to be on the same channel for potential broadcasts. | 03-31-2011 |
| 20100002709 | Systems and Methods for Network Routing Using Virtual Network Node Locations - Systems and methods for routing packets using node virtual locations are disclosed. Such a virtual location may be determined, for example, by determining a geographic location that is central to other nodes with which the node can communicate. In certain embodiments, a node's virtual location may more accurately represent an approximate center point of a node's communication range. In one exemplary embodiment, a node's virtual location is an average of the geographic locations of radio nodes with which the node is in communication. | 01-07-2010 |
| 20100002700 | Methods and Systems for Network Packet Routing Using Embedded Geographic Routing Information - Systems and methods for network packet routing using geographic information, for example, for routing packets in an IP communication network using geographic routing information embedded in a packet's IP address. One method comprises assigning a device's geographic location and including in its IP address a subnet prefix and a portion comprising an identifier indicative of the device' geographic location. One method facilitates routing of a packet by addressing the packet to a destination device with an IP address comprising a subnet prefix and a portion comprising an identifier indicative of the device's geographic location. The method may further comprise routing the packet from a source device to the destination device using the identifier. One embodiment is a system of a subnet of IP compatible nodes. One or more of these node devices are assigned an IP address comprising a subnet prefix identifying its respective subnet and a portion comprising an identifier indicative of its geographic location. One or more router nodes may be capable of using the geographic location of an IP address in a packet to route the packet, for example to select to which subsequent node to send the packet. | 01-07-2010 |
| 20090235246 | Methods and Systems for Distributing Firmware Through an Over-the-Air Network - Systems and methods for over-the-air firmware distribution to battery-powered devices are disclosed. Such over-the-air distribution is accomplished, for example, using a non-battery-powered device as a buffer, for example, to reduce or eliminate the delay time of the over-the-air network. The firmware can be sent to and stored on a nearby, non-battery-powered device and then sent from there to the battery-powered endpoint device. The distribution of firmware to battery-powered devices may be implemented in an AMI system, a mesh network, a multi-channel radio network, or any other environment in which firmware distribution is desirable. | 09-17-2009 |
