摘要： A system for measuring power in an electrical distribution circuit having at least three wires includes a Hall-effect generator directly coupled to one of the live wires of the circuit and current transformers coupled to the other live wires of the circuit. The output of each current transformer is magnetically linked to the Hall-effect generator. The excitation current for the Hall-effect generator is derived from the line potential between the live wires. The Hall-effect generator acts to produce an output whose magnitude is directly proportional to the product of the vector sums of the currents flowing in the live wires and the potential between the live wires. This power indicative output may be accumulated to produce an indication of energy consumed by a load connected to the live wires. A high frequency A.C. bias is applied to the Hall generator in order to linearize the output of the generator.

摘要： Systems and methods are provided for a utility meter assembly comprising: a plurality of meter components configured for measuring and collecting data, wherein the meter components include a transceiver operative for signal communications over a network; a faceplate, configured such that meter reading information is displayed on the front of the faceplate; an exterior cover configured to enclose the meter components and the faceplate, wherein the faceplate is forward of the plurality of meter components; and an internal dipole antenna situated within the exterior cover, wherein the internal dipole antenna is beyond the front of the faceplate and toward the front of the utility meter assembly. The internal dipole antenna is typically situated away from the meter components, so as to minimize interference by the meter components. The internal dipole antenna is typically tuned for optimal matching impedance in an 850 MHz or 1900 MHz receiving band, so that the desired receiving band Standing Wave Ration (SWR) is achieved, and also a specified minimum radiated power threshold is maintained.

摘要： A charge balance voltage-to-frequency converter utilizes CMOS circuitry to provide a digital pulse output proportional to an analog input signal. The converter approaches a desired charge balance by cycling between a charging and a discharging state. A clock signal provided by a stable oscillator is applied to a clock input of a CMOS D-type flip-flop. The analog input signal effectively is fed to a non-inverting input of an integrating amplifier. The output of the integrating amplifier is fed to the D input of the flip-flop, which input has a threshold level. The Q output of the flip-flop is connected via a voltage divider to an inverting input of the integrating amplifier. This configuration eliminates the need for a dual polarity power supply. When the output of the integrating amplifier rises above the threshold level of the D input, on the next rising edge of the clock signal, the flip-flop sends feedback pulses to the inverting input, thus beginning the discharge state. Each feedback pulse causes the integrating amplifier to discharge a predetermined amount. When the output of the integrating amplifier falls below the D input threshold level, feedback pulses are inhibited, and the charging state begins again. The output pulses from the flip-flop, when accumulated over a period of time, represent the charge required to balance the charge provided by the input signal. The feedback pulses are summed by an accumulator to provide an indication of the converter input.
