A fuel flow meter assembly for detecting fraud caused by tampering. The fuel flow meter assembly comprises a fuel flow meter comprising a shaft and a fiber optic displacement sensor operatively connected to the fuel flow meter shaft for generating information representative of an amount of fuel delivered through the fuel flow meter. The fuel flow meter assembly also comprises at least one transponder coupled with one of the fuel flow meter shaft and the displacement sensor. Further, the fuel flow meter assembly comprises at least one interrogator electronics coupled with the other of the fuel flow meter shaft and the displacement sensor. The at least one interrogator electronics is configured for remote electronic communication with the at least one transponder.

Fuel dispenser flow meter fraud detection and prevention

An apparatus and method of transmitting data between two inductively coupled circuits. The method includes providing a transmitting circuit, providing a receiving circuit spaced from the transmitting circuit, and generating a data signal in the transmitting circuit. The data signal includes a first component representing the data, and a second component identifying a portion of the first component. The apparatus includes a transmitting circuit having a transmitting coil. The transmitting circuit generates electrical energy in the transmitting coil. The apparatus further includes a receiving circuit spaced from and inductively coupled to the transmitting circuit. The receiving circuit includes modulating means for generating a carrier signal including a first component encoding a plurality of consecutive data signals, and a second component identifying the beginning of respective ones of the data signals.

A method and apparatus for remotely measuring the pressure and temperature of gas in a vehicle wheel. The vehicle includes a frame member and a vehicle wheel mounted for rotation relative to the frame member about a rotation axis. A transmitting circuit is mounted on the frame member. The transmitting circuit includes a transmitting coil and generates electrical energy in the transmitting coil. A receiving circuit is mounted on the vehicle wheel for movement therewith such that, as the vehicle wheel rotates relative to the frame member, the receiving circuit is inductively coupled to the transmitting circuit. The receiving circuit includes a sensor for generating a data signal corresponding to a physical characteristic of the vehicle wheel and a wireless communication circuit for receiving the electrical energy from the transmitting coil to remotely power the receiving circuit and for transferring the data signal from the receiving circuit to the transmitting circuit.

Method and apparatus for effiviently phase modulating a subcarrier

A preamplifier system adapted for a Loran receiver includes a buffer amplifier receiving the signal from the antenna at its input and a tuned circuit connected between the input of the buffer amplifier and ground. The tuned circuit includes a parallel combination of a resistance, capacitance and inductance with values selected such that a resonant frequency is provided substantially at or near the carrier frequency of the Loran signal to pass it while higher and lower frequencies, constituting extraneous noise signals, are substantially attenuated. In particular, low frequency, e.g. 60 Hz signals and DC from sources such as precipitation static, are shunted to ground through the parallel inductor in the tuned circuit so that these low frequency components do not affect the performance of the receiver. A secondary filter section is connected to the output of the buffer amplifier and has components that may be selected in value such that the overall transfer function of the preamplifier, including the tuned input circuit, has a desired bandpass characteristic. Thermal noise contributed by the parallel resistor in the tuned circuit may be reduced by feeding back the output of the buffer amplifier through the resistor to effectively reduce its noise contribution while leaving the effective input resistance the same. Notch filters may be incorporated with the input tuned circuit to reject strong extraneous signals within the passband.
