DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS

[0031] In referring to the schematic as shown in FIG. 1, therein is shown a dispenser D, which includes the upper part of the dispensing hose 31, which connects with the safety break 10, as noted in the art, and then further attaches with the portion of the dispensing hose 32 that connects with the nozzle 33. A flapper switch 36 is included within the seat for the nozzle, and a proximity sensor 37 can also be provided therein. 33 is the nozzle for the fuel pump. Then, the dispenser has a point of sale system 34, that provides information for the customer delivering gas to his/her vehicle. Then, within the dispenser, as at 35, are the fuel/shear valves, that are located within the dispenser, or they may be located below the dispenser, as noted at 35a, as can be seen. FIG. 1, as noted, is a typical dispenser configuration, with the smart safety break communications device of this invention, that may be optionally connected with the dispenser, in order to shut-off the flow of fuel when, as previously summarized, a customer may inadvertently drive off with the fuel dispensing nozzle and as connected with its hose, still inserted within the fuel fill pipe of the vehicle.

[0032] Referring further to the drawings, wherein like numbers refer to like items, the number 10 identifies a preferred embodiment of a wireless communication safety break device constructed according to the present disclosure. With reference now to FIG. 2, the wireless communication safety break device 10 is shown to comprise an upper safety break portion 12 having a fuel inlet 14, an upper portion check valve 16, an upper portion communications device 18, an upper portion contact point or switch 20, a lower safety break portion 22 having a fuel outlet 24, a lower portion check valve 26, a lower portion contact point or switch 28, and a locator device 30. Although not shown, the fuel inlet 14 is connected to a portion of a hose 31 of a fuel pump, and fuel flows from the portion of the hose into the fuel inlet 14. The fuel outlet 24 is also connected to another portion of the hose 32 which terminates at a fuel dispensing nozzle 33. As can be appreciated, in normal operation, fuel is allowed to flow through the device 10 and the check valves 16 and 26 are normally opened. The lower safety break portion 22 is adapted to separate from the upper safety break portion 12 when the nozzle is left in a fuel inlet of an automobile. Once a predetermined pull force is reached, as when a vehicle wrongfully drives off, the lower safety break portion 22 will separate from the upper safety break portion 12. The check valves 16 and 26 will close to shut off the fuel pump and to prevent any fuel from escaping from the remaining portion of the hose connected to the fuel pump and the extracted portion of the hose connected to the nozzle. In this manner, a fuel leak is prevented, and any possibility of a fire is diminished or eliminated.

[0033] Once the lower safety break portion 22 separates from the upper safety break portion 12 the upper portion contact point or switch 20 is no longer connected to the lower portion contact point or switch 28. This open circuit is detected by the upper portion communications device 18 which sends a signal to a POS system 34 to complete the fueling transaction instantly and to charge the credit or debit card that was used to initiate the fueling transaction. If the flow of fuel from the pump has not been shut off, the upper portion communications device 18 may also control this function to shut off the pump or close a valve 35. Alternatively, the upper portion communications device 18 may also send a signal to the flapper switch 36 in the dispenser holster or a proximity sensor 37 to stop the transaction and/or the flow of fuel. With the sale abruptly completed, the station owner will not experience a financial loss on the sale of the fuel and will not have to pursue the customer. Also, the open circuit is detected by the locator device 30 which is programmed to transmit a location signal. Use of the location signal will allow the station owner to receive a signal and to recover the extracted equipment, such as the portion of the hose, the nozzle, and the lower safety break portion 22. Further, locator device 30 will allow the station owner to identify the customer who drove off and to seek reimbursement from the customer for any damage to the device, station, or other equipment.

[0034] By way of example only, the upper portion communications device 18 may be a microcontroller such as a device manufactured by STMicroelectronics known as STM32F756 family of micrcontrollers or other similar microcontroller that may be used and which accommodate low power radio frequency (RF) transmitting and receiving. The device 18 is encased within the upper safety break portion 12. Also, by way of example only, the locator device 30 may be a nano or micro GPS (global positioning system) positioning and locating type device or chip such as the Multi Nano Spider ORG4500-R01 module manufactured by OriginGPS.

[0035] The locating device 30 may also incorporate a communications device using a microcontroller similar to the upper portion communications device 18.

[0036] FIG. 3 illustrates a cross-sectional view of the wireless connection safety break device 10 constructed according to the present disclosure shown in a disconnected or separated configuration. The wireless communication safety break device 10 is shown to comprise the upper safety break portion 12 having encased therein the fuel inlet 14, the upper portion check valve 16, the upper portion communications device 18, and the upper portion contact point or switch 20. The lower safety break portion 22 has encased therein the fuel outlet 24, the lower portion check valve 26, the lower portion contact point or switch 28, and the locator device 30. The lower safety break portion 22 is shown separated or disconnected from the upper safety break portion 12. In this manner, any connection between the contacts or switches 20 and 28, whether wired or wireless, has been broken. Once the connection is broken the upper portion communications device 18 sends a signal to either the POS system 34, a valve 35 supplying or allowing fuel to the dispenser, the flapper switch 36, proximity switch 37, or any combination of these options so that the fueling transaction is successfully completed and/or the fuel flow has stopped. This will enable the credit or debit card that was used to initiate the fueling transaction to be charged so that the station owner does not lose receiving funds for the dispensed fuel. Also, the broken connection initiates the operation of the locator device 30. The locator device 30 is programmed or engineered to generate and transmit a location signal so that the station owner will be able to retrieve the lower safety break portion 22, the portion of the hose 32, and the nozzle 33 so that these components can be reused. Further, it is contemplated that the lower safety break portion 22 may be reconnected to the upper safety break portion 12 in order for the device 10 to be utilized again.

[0037] FIG. 4 shows a communications flow chart of what would happen from the time a safety break has occurred to the time the hardware has been replaced. As noted, this flow chart indicates that when the safety break 10 has separated, being of the type of safety break as identified in this description, when separation has occurred, the upper safety break microcontroller transmits a signal to the safety break transceiver module. Simultaneously, the lower safety break microcontroller functions in conjunction with a mini GPS locator module, and also communicates with the communication module cellular Wi-Fi Lan. Through this, the transmitted signal from the breakaway is received by the station owner, providing the owner with notification as to the time of the break, and also, through its GPS, indicates the location of the separated hardware. Simultaneously, the safety break transceiver module transmits a signal to the point of sale internal wireless which incorporates the transceiver module, and also submits a signal to the holster flapper switch or proximity sensor transceiver module, and to the fuel valve shut off switch which incorporates the transceiver module. When these modules are operated, after separation has occurred, and since these are located either in the dispenser, or below thereof, in combination with its various valves, it indicates a stop transaction, meaning that fuel flow should cease, and then does stop the fuel flow from the dispenser and through the hose. In addition, the safety break will have shut off the flow of fuel also. Then, once the hardware has been located, returned, inspected, it is then replaced to its fuel dispensing position, meaning that the safety break will be reconnected, and allow the subsequent flow of fuel to customers, for routine dispensing. Obviously, when the hardware has been separated, this means that its nozzle 33, and the lower part of its dispensing hose 32, will have separated, and have been driven off inadvertently by the driver of the vehicle, unknowingly forgetting that the fuel dispensing nozzle was still located within the fill pipe of its vehicle fuel tank.

[0038] One configuration might be the valve in the base of the dispenser having the additional function of wireless communication with the safety break. Currently, safety valves in the base of the dispenser are designed for impact to shut off without leaking. Some valves may be temperature sensitive to mechanically shut off in case of a fire. The same on a different valve would now be in communication with the safety break to shut off in the event of a drive-a-way.

[0039] Another configuration would be the flapper would be the flapper switch or proximity sensor in the dispenser holster having addition function of wireless communication with the safety break. Currently, flapper switches in the dispenser holsters are designed to close when the fuel nozzle is returned to the holster to complete the transaction and/or stop the flow of fuel. In the absence of the nozzle being returned to the dispenser holster, the flapper switch or proximity sensor would be engaged by the wireless communication safety break to complete the transaction and/or stop the flow of fuel in the event the safety break is disconnected or separated.

[0040] From all that has been said, it will be clear that there has thus been shown and described herein a wireless communication safety break device. It will become apparent to those skilled in the art, however, that many changes, modifications, variations, and other uses and applications of the subject wireless communication safety break device are possible and contemplated. All changes, modifications, variations, and other uses and applications which do not depart from the spirit and scope of the disclosure are deemed to be covered by the disclosure, which is limited only by the claims which follow.
