  • Patent number: 6462713
    Abstract: For use with an electric meter chassis having a dielectric housing protruding therefrom, an antenna for allowing electric meter circuitry within the chassis to communicate wirelessly through the dielectric housing and a method of manufacturing the same. In one embodiment, the antenna includes: (1) antenna elements, located within the dielectric housing and adapted to transmit and receive electromagnetic radiation and (2) a balance circuit, coupled to the antenna elements to cause the antenna elements to act as an antenna and couplable to an unbalanced output port of a wireless communication circuit, that balances an impedance of the unbalanced output port thereby to balance the antenna.

  • Patent number: 5122735
    Abstract: A digital power meter achieves enhanced accuracies through the utilization of a sequence of meter stage improvements. Such improvements include the utilization of a digital phase shift based cycle phase realignment following the scaling function of the meter. The cycle phase corrected signals are digitized utilizing a sampling procedure wherein two samples of both current and voltage are taken within a precisely defined sampling interval. These samples are improved by the application thereto of a truncation correction and are averaged prior to being combined to provide quantity signals such as watt, VAR, volt, amperes, and the like. By developing subinterval transfer of components of these quantities to an overflow register, errors otherwise occurring at this stage of metering are substantially eliminated.
