Abstract: A fuel dispensing system and method for preventing unauthorized fueling by controlling access and delivery of fuel from a fuel dispenser, based on information received from a vehicle or container via remote communications during a fueling operation. The vehicle transmits a signal including fuel delivery indicia to the dispenser. The dispenser uses the fuel delivery indicia to determine whether the vehicle is receiving fuel and determines whether it is delivering fuel. The dispenser maintains fuel delivery authorization if the vehicle indicates that it is receiving fuel and the dispenser is delivering fuel. If the vehicle indicates that it is not receiving fuel and the dispenser determines that it is delivering fuel, the dispenser may generate an output signal to identify an improper fueling condition and stop fuel delivery.

Abstract: A fuel dispenser includes vapor and hydrocarbon concentration sensors positioned in the vapor recovery line to provide accurate feedback relating to the speed and concentration of hydrocarbon laden vapor recovered by a vapor recovery system. The sensors provide diagnostic information about the vapor recovery process as well as insuring that the vapor recovery process is carried out in an efficient manner. Additionally, the sensors may be positioned in an underground storage tank vent apparatus to monitor fugitive emissions from the underground storage tank.

Abstract: The present invention provides a fuel dispenser capable of sensing the proximity or location of a customer relative to the fuel dispenser without requiring direct customer contact and controlling the display or aspects of the display accordingly to conserve energy, reduce heat generation or draw the customer's attention to the display once the customer is within a relative proximity to the fuel dispenser.

Abstract: A system enables lottery ticket transactions in a fueling forecourt by permitting the purchase of lottery tickets at a fuel dispenser. In the system, customers pay for lottery tickets through the fuel dispenser payment acceptors in conjunction with fuel purchases. Payment may be by cash, credit, or wireless credit storage device, with the cost of the lottery ticket or tickets added to the cost of the fueling transaction. The lottery ticket dispensers may be integrated within the individual fuel dispensers, one to each dispenser, or may be apart from the fuel dispensers with one or more lottery ticket dispensers located elsewhere within the forecourt area. The system provides a range of lottery ticket choices including pre-printed tickets, random-number tickets, and customer-number tickets. The system provides a convenient alternative to in-store lottery ticket transactions by allowing fueling customers to purchase and receive lottery tickets without need of entering the store.

Abstract: A system and method for determining whether a vehicle is equipped with an ORVR system. A processor receives a signal from a fuel pump or the like indicating the fuel being dispensed by the fuel dispenser. The processor is programmed to determine a threshold vapor concentration level based on the signal. Processor further receives a signal from at least one environmental sensor indicating at least one environmental condition to which the fueling operation is exposed. The processor is further programmed to adjust the threshold vapor concentration either up or down dependent upon the environmental condition. Finally, processor receives an actual vapor concentration from a vapor sensor. The processor then compares the actual vapor concentration value with the adjusted threshold vapor concentration value to determine whether the vehicle is equipped with an ORVR system.

Abstract: The present invention provides communication servers at each device in a fueling environment and connecting the servers to a common network. The network may be a local network or a largely remote network, such as the Internet. Preferably, in either embodiment, primary communications between these devices and any devices accessible via the Internet use the hypertext transfer protocol (HTTP) and hypertext markup language (HTML). In particular, each device server is adapted to facilitate real-time access between the device server and the remote device upon access of a particular page, script or function. In particular, the present invention relates to embedding executable content onto an HTML page so that when the page is loaded into an HTML browser after being accessed, the executable content starts running automatically.

Abstract: A fuel dispensing system compensates for varying fuel source flow rate requirements based on fuel dispenser feedback signals. A pumping system pumps fuel from one or more fuel sources to one or more fuel dispensers through associated conduits. When actively dispensing fuel, each fuel dispenser monitors its actual fuel discharge rate and adjusts an integral flow control device to maintain a nominal fuel discharge rate. When an active fuel dispenser fails to achieve its nominal fuel discharge rate, it indicates this condition to the pumping system via its dispenser feedback signal. In response, the pumping system increases its pumping rate until the fuel dispenser achieves its nominal fuel discharge rate. Other active fuel dispensers adjust their flow control devices as needed to maintain their nominal fuel discharge rate in response to the adjusted pumping rate.

Abstract: A pressure sensor includes a pair of inputs for determining the pressure within a vapor recovery path. The inputs are positioned about a flow restrictor within the vapor recovery path. The vapor recovery path may include a mounting platform for attaching the pressure sensor and positioning the inputs relative to the flow restrictor. In one embodiment, a vapor sensor may also be positioned within the vapor recovery path. An inlet port and an outlet port direct vapor from the vapor recovery path to a sensor. The inlet and outlet ports are positioned relative to the flow restrictor for forcing the vapor through the sensor. In this embodiment, a common flow restrictor within the vapor recovery path may accommodate both the vapor sensor and the pressure sensor. If vapor is not being returned in the vapor return path properly, the fuel dispenser may set an alarm condition and/or shut down the fuel dispenser operation.

Abstract: A fuel dispenser system having a storage tank and a fuel delivery hose extending from the storage tank and terminating at a nozzle. A vapor recovery line extends between the nozzle and the storage tank. The vapor recovery line extends between the nozzle and the storage tank and has a section with a first larger diameter and a second section having a smaller diameter. A vapor pump is operatively connected to the vapor recovery line for moving vapor along said vapor recovery line. A chamber is positioned along the vapor recovery line and includes inlet and outlet ports, and a main sensor chamber. The inlet port connects to the vapor recovery line at a point having the larger diameter. The outlet port connects a point of the smaller diameter. Each of the ports connects to the main sensor chamber where a sensor is positioned for determining the vapor concentration.

Abstract: A vapor recovery system for a fuel dispenser having a valve positioned in the hanging hardware for testing for leaks along a vapor recovery line. Vapor valves placed along the vapor recovery line allow for isolating sections of the recovery line to determine the position of any leaks. A vapor pump positioned on the vapor recovery line provides for changing the pressure within the line and a vapor sensor positioned on the vapor recovery line determines the amount of pressure within the line. A control system controls the vapor pump and valves and receives signals from the pressure sensor for determining the position of leaks along the vapor recovery line.

Abstract: A vapor system for a fuel dispenser having at least one vapor sensor placed along a vapor recovery line for determining the amount of captured vapor. The vapor amounts are determined by the sensor at a number of times during the fueling process. These are sent to a control system which compares the amounts and determines whether they are within a predetermined range. Consistent readings indicate that the vapor recovery system is operating correctly. Inconsistent results indicate either a leak within the vapor recovery line, or fuel is being drawn into the vapor recovery line. These problems within the vapor recovery system can be diagnosed and the necessary corrective steps may be implemented.

Abstract: A system and method to store a sequence of data records relating to attributes of interactions between fuel dispensers and tags. The data records may be stored on the tag or at a location remote from the tag, such as a fuel dispenser, central site controller or other network. The data records may contain the identity of the dispenser, tag and any attribute of a received signal, such as frequency band or signal strength, or other attribute indicative of proximity. Every dispenser that attempts to communicate with a tag in question adds its own interaction data to a limited history of a tag's past interactions with the same and other dispensers. When a dispenser or central site control system examines the contents of the interaction histories, the detected presence of other dispensers or the relative strength of the recorded interaction attributes will determine what, if any, action is to be taken by the dispensers or central site control system to communicate with the tag at issue.

Abstract: A service station vapor management system including a plurality of vapor handling subsystems and a controller in electronic communication with the vapor handling subsystems for monitoring subsystem operation, determining an overall service station V/L ratio and controlling subsystem operation to maintain the V/L ratio or total site hydrocarbon emissions within predetermined limits.

Abstract: A method and apparatus for detecting tampering with a fuel dispenser digital pulse stream during dispensing of a fuel. The method includes generating a digital pulse stream indicative of the volume and flow rate of fuel dispensed wherein the pulse stream includes an identifying pulse anomaly; storing a digital pulse stream signature in a memory device wherein the stored signature includes the identifying pulse anomaly; comparing the incoming digital pulse stream with the stored digital pulse stream; and allowing fuel delivery to continue if the incoming digital pulse stream generated by the pulse generator is substantially similar to the stored digital pulse stream signature.

Abstract: The invention relates to an interactive fuel dispenser system having a plurality of fuel dispensers operating in conjunction with a local server. Each dispenser generally has two fueling positions, each with a graphical user interface through which a customer interacts. In contrast with the recent trend in turning fuel dispensers into super computers, applicants' provide a dispenser architecture that need only be sufficient to establish interactivity with a server to create multimedia applications and carry out POS functions with a browser interface. Each fueling position acts as a client of a local server at the fuel station store. In the preferred embodiment, each fueling position client also may access remote servers connected to the same network in which the fueling position clients and the local server are connected. Preferably, this network is or is connected to the Worldwide Web of the Internet.
