摘要： A system and method of detecting fuel theft at a fuel dispenser. The system has a fluid flow meter, a pulser operatively coupled to said fluid flow meter, and a control system in electrical communication with the pulser. The control system is configured to calculate a flow rate of fuel being dispensed from a gasoline dispenser during a single dispensing transaction. The flow rate is sampled at predetermined time intervals during the single dispensing transaction. The system then compares the sampled flow rates to a predetermined flow rate pattern indicative of potential fraud. A shutoff signal is then provided to the dispenser to stop fuel flow through the dispenser if the sampled flow rates are substantially similar to the predetermined pattern.

摘要： A gasoline pump apparatus comprises one or more pump nozzles, a sensor configured to detect nozzle removal from and replacement to a nozzle storage bay, and a first housing enclosing at least some gas dispensing apparatus. In addition, a second housing encloses at least one video display and at least one video display controller. The at least one video display controller is coupled to the sensor such that the video display output changes with changes in nozzle position. In some embodiments, the second housing is configured to be explosion proof.

摘要： A system including a pulse-generating device can comprise of at least one analog sensor and at least one unit for signal-processing is arranged to detect the analog signal and to generate signal changes having a higher frequency. When generating signal changes in connection with the determination of the amount of fuel dispensed from a fuel pump unit and a frequency generator for generating a periodic analog signal having a frequency is generated, which corresponds to a fuel volume flow in the pump unit. The amplitude of the analog signal is detected and then signal changes having a higher frequency are emitted, which is dependent on and higher than the frequency.

摘要： The circuit arrangement includes a transformer having a primary side included in at least one phase conductor of a polyphase supply for the load. A control circuit is connected to the secondary side of the transformer and includes a threshold circuit receiving a control signal from the transformer, a memory circuit receiving a threshold signal from the threshold circuit, a bistable switch connected to the threshold circuit and the memory circuit and switched, by the threshold signal, to a position preventing the stored signal from being passed on from said memory circuit, and a controlled electronic switch inserted in the phase conductor and controlled and opened by the stored signal. A resetting switch is operable to reset the control circuit to the initial state, and a delay device may be interposed between the memory circuit and the controlled electronic switch to delay opening of the latter until after a subsequent operation of the repetition-blocking device. The resetting switch controls a further switch, connected between the transformer and the threshold circuit, the memory circuit and the bistable switch.
