  • Method of RF-based communication
    Patent number: 6219655
    Abstract: An RF based communication system includes a transmitter for transmitting a signal. The transmitter is powered by an external power source and has a transmitter counter for generating a count. The count is linearly incremented over time. The transmitted signal includes the count at the time that the signal is transmitted. A receiver is communicatively coupled to the transmitter for receiving the signal transmitted by the transmitter. The receiver has a receiver counter, the receiver counter being asynchronous with respect to the transmitter counter.
    Type: Grant

  • Time-of-use and demand metering in conditions of power outage
    Patent number: 5918380
    Abstract: A metering system for metering the consumption of electrical energy to provide time-of-use and demand metering in the presence of at least one power outage event includes an encoder device for transmitting a radio frequency (RF) signal and a interrogate/receiver device for receiving the radio frequency signal transmitted by the encoder device. The encoder device has apparatus for sensing electrical power consumption and for sensing a power outage. Additionally, the encoder device has apparatus for periodically generating an encoded RF signal for transmission by the encoder device. The signal has a plurality of discrete components, each of the components being related to electrical power consumption over a selected interval of time. The signal further has a power outage flag associated with each discrete component, the flag being set for any interval of time during which a power outage is sensed. A meter counter for incrementally increasing a count as a function of time is included.
