Abstract:
A monitoring system and method for monitoring performance of individual powers sources in a distributed power source system. A monitoring module is coupled to each of the power sources, or to each string of serially connected power sources, to monitor and collect data regarding current, voltage, temperature and other environmental factors at the power source. The collected data is transmitted over a power line to a central analysis station for analysis. Data collected from each source indicates malfunction or degradation at the source. Comparison of data collected from adjacent sources filters for environmental factors impacting neighboring sources such as cloudy days for a solar panel. Comparison of data collected from the same source at different times indicates soiling or degradation of the source with time or periodic events such as a moving shade from an adjacent building.
Abstract:
Methods of operating a communication node are provided. A method of operating a communication node may include receiving data from an electric grid device via a network interface. The method may include processing the data from the electric grid device at the communication node. Moreover, the method may include transmitting a filtered portion of the data to an electric utility head end system, after processing the data at the communication node. In some embodiments, a method of operating a communication node may include using a message broker controlled by a virtual machine in the communication node to provide a protocol to interface with a field message bus that includes a standards-based or open-source Application Programming Interface (API). Related communication nodes and computer program products are also described.
Abstract:
A meter apparatus and method of operating a removable meter apparatus are described. The meter apparatus includes a tag associated with unique tag identification information and configured to be permanently affixed to a location housing at a unique physical location, and includes a removable meter unit configured to mate with the location housing and receive the tag identification from the tag and report the tag identification to a data manager configured to associate an identifier of the removable meter unit with the tag identification and unique physical location, and associate configuration information for the physical location with the removable meter unit and the tag identification. The unique physical location can comprise a single-space parking location.
Abstract:
A system and method are presented for collecting and retrieving characterization data of measurement devices, such as flow meters. The system includes a meter, a radio frequency identification (RFID) tag for storing the meter characterization data, and electronics, such as a totalizer, to read the characterization data from the RFID tag and calibrate the meter measurements using the characterization data.
Abstract:
A communication device detects whether anomalous events occur with respect to at least one node in a utility network. The communication device has recorded therein threshold operating information and situational operating information. The threshold operating information includes data indicative of configured acceptable operating parameters of nodes in the network based on respective locational information of the nodes. The situational information includes data indicative of configured operation data expected to be received from nodes in the network during a predetermined time period, based on a condition and/or event occurring during the time period. The communication device receives operation data from nodes in the network, and determines whether the operation data from a node constitutes an anomalous event based on a comparison of the received operation data with (i) the threshold operating information defined for the node and (ii) the situational information. The communication device outputs notification of any determined anomalous event.
Abstract:
One example embodiment provides a method and system where a node in a utility network registers with one or more access point devices associated with one or more local area utility networks. The utility node generates a unique network address using a network address prefix of a network address associated with the access point device. The utility node registers with a DNS server. Messages sent to the utility node are routed through the access point corresponding to the received prefix used to generate the unique network address for the utility node. The network address for the utility node and access point may be IPv6 addresses and the network address prefix may be an IPv6 prefix, or may be an IPv4 address.
Abstract:
A measurement device, which communicates data to at least one system, and which has the capability of identifying measurement data returned by the system via the data communication as its own, and the capability to rule out manipulation of measurement values without use of a public or non-personal key. The measurement device includes at least an encryption and/or signature encoder that supplies information including a validity and reliability identifier for inspecting the integrity of the data, and compiles said information into a current data set and transfers it to at least said communication interface for transfer, and at least an encryption and/or signature decoder that inspects data sets returned via the communication interface using one or more keys in memory for integrity of data content and identification of the measurement device and, upon successful inspection of this data, supplies said data for further processing, evaluating or displaying.
Abstract:
A system for is provided for using telemetry data based on patient habit information or patient monitoring. One or more patient monitoring devices has a unique patient ID. The one or more monitoring devices acquire patient information selected from of at least one of, a patient's activities, behaviors and habit information, and patient monitoring. ID circuitry is at the patient monitoring device. The ID circuitry includes ID storage, a communication system that reads and transmits the unique ID from an ID storage, a power source and a pathway system to route signals through the circuitry. An alarm is at the patient monitoring device that provides an alert only when the patient is in a wake-state. A telemetry system is in communication with the patient monitoring device. The telemetry system includes a database of patient ID's.

Abstract:
A spa node comprising a spa controller, a power sense adapter configured to compute power being drawn by selected spa components; a spa network adapter, and a home network adapter, each of the three adapters including a wireless transceiver wherein the spa network adapter is configured to receive power data transmitted over a wireless link by the power sense adapter and to further receive status/performance data from the spa controller. The home network adapter is configured to receive power and status data transmitted by the spa network adapter over a wireless link and to convert that data to a form suitable for transmission to an Internet access point. The home network adapter is further linkable over the Internet to a central server, a dealer computer and a spa owner or user computer.
