Abstract: A portable data probe includes a portable housing, an optical transceiver circuit and a wireless communication circuit. The optical transceiver circuit is disposed substantially within the portable housing, but is also configured to be in optical communication with an exterior of the portable housing. The optical transceiver circuit is operable to convert between electrical signals and corresponding optical signals. The wireless communication circuit is also disposed substantially within the housing, and is operably coupled to the optical transceiver circuit. The wireless communication circuit is operable to communicate wireless signals to a remote wireless circuit.

Abstract: An electricity meter assembly has a meter mounting device and a measurement meter. The meter mounting device is operable to receive power lines of a load being metered, and includes a sensor circuit. The sensor circuit is operably connected to the power lines, and is operable to generate measurement signals representative of voltage and current signals on the power lines. The measurement meter includes a measurement circuit operable to receive measurement signals and generate energy consumption data therefrom. The measurement meter further includes a device that communicates information relating to the energy consumption data. The measurement meter is operable to be removably coupled to the meter mounting device such that the measurement circuit is operably connected to the sensor circuit to received the measurement signals when the measurement meter is coupled to the meter mounting device.

Abstract: An electronic utility meter includes a sensor module and a removable measurement module. The sensor module connects to the electrical system of a facility and includes voltage and current sensors. The voltage and current sensors is operable to receive voltage and current signals from the electrical system and generate measurement signals therefrom. The sensor module further includes an electrically safe interface. The removable measurement module includes a measurement circuit operable to receive measurement signals and generate energy consumption data therefrom. The measurement module also includes a device for communicating information relating to the energy consumption data. The electrically safe interface of the sensor module operably connects the voltage and current sensors to the measurement circuit, and further prevents physical contact of a human operator with the received voltage and current signals from the electrical system when the measurement module is removed from the sensor circuit.
