Disclosed are apparatus and related methodologies for transmitting data related to utility conditions between monitoring locations and a central and/or data collection facility using a meter reading system. Collection of both corrected and uncorrected data from meters is achieved to thereby provide backup data in case of corrector failure. The presently disclosed subject matter also provides for the collection of telemetry data and alarms from correctors and recorders over a meter reading system. Two-way communications over a meter reading system is also provided to permit data transmission to selected endpoint devices.

To provide a projected capacitive touch switch panel having sensor units that are easy to adjust and that minimally reflect visible light, and furthermore having adequate environment-resistance properties. A projected capacitive touch switch panel 1 comprising a glass substrate 2 that has a sensor unit 3 for performing detection along the X direction, and a glass substrate 4 that has a sensor unit 5 for performing detection along the Y direction, in which: the two glass substrates are laminated, and the sensor units are sandwiched between the glass substrates so as to face each other; each of the sensor units has a sensor electrode comprising an Al thin film, and a blackened film including at least one metal selected from Cr, Mo, and W; in the sensor unit 3 of the first glass substrate 2, the blackened film is formed on the surface opposite a touch surface of the glass substrate, and the Al thin film is formed on the blackened film; and in the sensor unit 5 of the second glass substrate 4, the Al thin film is formed on the surface of the glass substrate, and the blackened film is formed on the Al thin film.


There is provided a method and apparatus for determining the input impedance (Z_(L)) of an AC transmission line used for Power Line Communications (PLC), using a transmitted data packet having a preamble portion. The method comprises, at the analog-front-end (AFE) of the AC transmission line, determining the current through the AFE and the AC transmission line during transmission of the preamble portion of the data packet and determining the voltage during transmission of the preamble portion of the data packet. The method further comprises calculating the total impedance (Z_(t)) from the determined current and voltage. The total impedance (Z_(t)) includes the input impedance (Z_(L)) of the AC transmission line and the AFE impedance (Z_(AFE)). Finally, the method includes determining the input impedance (Z_(L)) of the AC transmission line from the total impedance (Zt).


Disclosed are apparatus and methodology for remotely configuring gateway devices in a gateway-based Advanced Metering Infrastructure (AMI) network. Remotely configurable gateway devices are provided for Internet Protocol (IP) communications between consumption measuring devices and a utility central facility. Communications between the gateway device and central facility may be by way of wired or wireless communications and may include configuration information multicast from the central facility to selected gateway devices.

Techniques for determining aspects of a topology of a smart grid are described herein, and particularly for determining if one or more electrical meters are connected to the same transformer. In one example, time-stamped voltage data is collected from at least two meters. The voltage data may indicate a slight transient change in voltage resulting from a consumer turning on or off an electrical load. In particular, the slight voltage changes may be sensed by all meters attached to a same transformer based on electrical load changes by any one of the customers on the same transformer. Using the time-stamped voltage data, a time-series of voltage-changes may be generated for each electrical meter. A correlation between the time-series of voltage-changes of pairs of meters may be calculated, to thereby determine an affinity between the meters, and particularly if they are connected to a same transformer.

Techniques for detecting electrical meter bypass theft are described herein. In one example, a time-series of voltage-changes and current-changes associated with electrical consumption measured at a meter are obtained. The time series may track associated voltage and current changes at short intervals (e.g., 5- minutes). The voltage and current changes may indicate a slight voltage change when an appliance is turned on or off. An analysis (e.g., a regression analysis) may be performed on the voltage-changes against the current-changes. Using the correlation from the analysis, it may be determined if the meter was bypassed.


A new device is deployed to an area in which a network is provided. The new device may join the network using a single handshake via a neighboring device that is a member of the network and register with a network management system managing the network. If the network is overloaded or has limited bandwidth remaining, the network may refuse to admit the new device, or if the new device is isolated, may force some devices that are members of the network to leave or migrate from the network to allow the isolated device to join the network.

Disclosed are techniques to minimize the electricity consumption of battery powered devices during network communications and performance of other functions. Example techniques include efficiently discovering other mains powered and battery powered devices within communication range of the battery powered device. In another example, techniques enable a battery powered device to serve as a relay for one or more other battery powered devices. In another example, techniques ensure that transmissions to and/or from battery powered devices are delivered efficiently and with low latency. In yet another example, techniques determine whether and under what conditions a battery powered device should migrate from one network to another. In the event of migration, example techniques minimize battery consumption associated with the migration.
