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).


Mechanisms and methods for minimizing trapped air in a fluid flow device are disclosed. An example device includes a first chamber having an inlet and outlet for substantially horizontal fluid flow, a second chamber at least partially openly disposed above the first chamber, and a tube vertically disposed in the second chamber from the second chamber ceiling to the first chamber. When fluid flows from the inlet to the outlet, at least a portion of the fluid flows into the second chamber and air collected at its ceiling moves down the tube and into the first chamber. The ceiling of the second chamber may be contoured such that a first internal height at a first location of the second chamber is greater than a second internal height at a second location, forming a pocket at the ceiling at the first location where air can collect before entering the tube.

The vacuum tube subject to the present invention comprises a filament and two pairs of a grid and an anode. The filament is tensioned linearly and emitting thermoelectrons. Both of the anodes are formed on the same face on a planar substrate. The filament is arranged parallel to the planar substrate at a position facing both of the anodes. Each of the grids is arranged, such that the grid faces the anode in the same pair at a first predetermined distance from the anode and has a second predetermined distance from the filament, between the anode and the filament. The vacuum tube comprises an intermediate filament fixing part fixing the filament at a position corresponding to an intermediate point between the anodes of the two pairs.

Techniques for frequency-hopping sequence-generation are described herein. In one example, a sequence of pseudo random numbers may be used to generate a scrambling sequence. The scrambling sequence may be used to map an unscrambled sequence of channels into a scrambled sequence of channels. Channel-repeats may be detected in the scrambled sequence of channels and resolved. Channel whitening may be performed to reduce channel overuse resulting from the channel-repeat resolutions. The scrambled sequence of channels may be provided to a radio to enable the radio to tune to the channels indicated by the scrambled sequence of channels.

An object of the present invention is to provide a vacuum tube with a structure close to that of an inexpensive and easily available vacuum fluorescent display which easily operates as an analog amplifier. A vacuum tube subject to the present invention comprises: a filament which is tensioned linearly and emits thermoelectrons, an anode arranged parallel to the filament, and a grid arranged between the filament and the anode such that the grid faces the anode. The present invention is characterized in that a distance between the filament and the grid is between 0.2 mm and 0.6 mm, including 0.2 mm and 0.6 mm.

Disclosed are apparatus and methodology for improving communications among battery operated network endpoints and a central facility. A battery operated endpoint may determine its remaining battery capacity and decide whether it is able to provide message repeating services to other endpoints within the network. The endpoint may make such decision based also on its own communications reliability to a central facility either directly or via other endpoints operating as repeaters.


Techniques detect an electrical phase used by electrical network devices (e.g., a transformer, electrical meter, etc.). Voltage measurement data is obtained, such as from electrical meters. The voltage measurement data may be associated with a timestamp, and may be made at intervals over a period of time. Voltage changes may be calculated using the voltage measurement data. In an example, the voltage change is a difference determined between sequential voltage measurements. In some instances, voltage changes data is removed if it exceeds a threshold. An initial classification of network devices (e.g., randomly or by assumed electrical phase) is determined. A clustering technique (e.g., k-means) is applied, wherein the classification is updated in a manner that segregates the network devices according to actual electrical phase.


A method for detection of a utility meter having been tampered with, in particular a water or heat meter having been tampered with, and a meter for detecting such tampering are provided- The utility meter comprises a flow measurement portion in which the flow of water is measured. The method comprises detecting a presence of air in the flow measurement portion and evaluating a fraud condition, wherein the fraud condition comprises that air is present in the flow measurement portion for a first period of time or more. In response to the fraud condition being evaluated as met, an alert is generated.
