    摘要: Methods and systems for detecting tampering of a remote display. According to one method, a first data integrity result is generated by performing a first data integrity operation on display data to be displayed on the remote display at a secure module. The display data is transmitted from the secure module to the remote display security module. The remote display security module receives the display data. A second data integrity result is generated by performing the first data integrity operation on the display data received at the remote display security module. A determination is made as to whether the remote display has been tampered with at the secure module if the first data integrity result does not match the second data integrity result.

    摘要: An automated payment system for use in a service station. The system includes at least one fuel dispenser for dispensing fuel and having a user interface for directing how payment for the fuel is to be processed. The system also includes a payment terminal positioned in proximity to the fuel dispenser for receiving the payments. The terminal has rigid outer walls forming an enclosed interior section for housing the payments. In one embodiment, the terminal has rigid outer walls forming a substantially H-shape with two indents positioned on the exterior of the payment terminal. A pair of support posts are firmly mounted within the indents for securing the payment terminal in position. Mounting mechanisms may attach the payment terminal to the support post and be positioned such that they are contained within the terminal and post to restrict access.

    摘要: A single meter blending fuel dispensing system utilizing a pair of proportional flow control valves each having a pressure transducer positioned aft of the valve flow control mechanism. A computer controller is used to program a desired fuel mixture by varying the pressure for each flow control valve. A pressure decrease in one valve produces a corresponding pressure increase in the other valve. A third pressure transducer can be situated downstream of the valves and is set such that the pressure it receives cannot exceed that of the two valve pressures. Flow meters can be substituted for the pressure sensors. A calibration method for calibrating the positive displacement meter is also disclosed. At installation the positive displacement meter is at its most accurate and is synchronized with the less accurate pressure sensors or flow meters. As time passes and the positive displacement meter wears it can be re-calibrated using the baseline data and the pressure sensors or flow meters which are not subject to mechanical wear.

    摘要: A fuel dispenser having a controllable audio/video program display includes a fuel pump and delivery path, a program media display, and a prerecorded program and a multi-media controller to direct program signals to the program media display. Apparatus is included for recovering multi-media control signals embedded in the program signals in the prerecorded program including a detector for detecting predetermined portions of the program signals having embedded control signals and rerouting means for rerouting the control signals in the program signals to an output. The multi-media controller is coupled to the rerouting means to act on the program signals as directed to the media display.
