In the drawings, like numbering represents like elements between the drawings.

DETAILED DESCRIPTION

(8) Certain exemplary embodiments will now be described to provide an overall understanding of the principles of the structure, function, manufacture, and use of the devices, systems, and methods disclosed herein.

(9) Fuel dispenser systems are provided that can utilize non-specialized electronics (e.g., existing/standard electronics designed for dispenser systems of different or less hazardous fuel) while complying with the requirements for use in an environment classified as hazardous due to the presence of explosive gases. Such systems can be used, for example, to protect and allow for the use of electronic components that are otherwise not rated or designed for use in the hazardous environment. For example, the systems described herein can include a nozzle for dispensing CNG while utilizing electronics that are not specially designed for such a hazardous environment.

(10) FIG. 1 illustrates one embodiment of a fuel dispenser system. System 100 generally includes a first housing in the form of an electronics module 110. The electronics module 110 can contain various electronics, including one or more of, for example, a processor, computer memory, display, input device such as a keypad, credit card and/or cash receiver, printer, and other electrically powered components. System 100 also includes a second housing in the form of a CNG module 120, a CNG nozzle 121 that is coupled to the CNG module 120, and a partition housing 101 having a sealed partition part 102 located between the electronics module 110 and the CNG module 120. The sealed partition part 102 forms one wall of the partition housing 101 (as shown for illustration purposes by the cutaway in the housing), and the part 102 is configured and arranged to separate and seal (protect) the electronics module 110 from the CNG module 120. For example, in some embodiments, the sealed partition part 102 is configured to prevent the electronics module 110 from being exposed to the gas vapors that may be emitted from the CNG module/nozzle 120/121. In some embodiments, the sealed partition part 102 provides a hermetic seal in the housing 101 to act as a barrier from exposing internal electrical components of the electronics module 110 to any gas vapors.

(11) FIG. 2 illustrates another embodiment of a fuel dispenser system. System 200 generally includes a first housing in the form of an electronics module 210 and a second housing in the form of a CNG module 220. A CNG nozzle 221 is coupled to and seated within the CNG module 210 on one side of the first housing, and a sealed partition part 202 (as shown for illustration purposes by the cutaway in the housing) is located inside a partition housing 201 positioned between the CNG module 220 and the electronics module 210. On the other side of the electronics module 210, the system includes a fuel nozzle 222 coupled to and seated within a third housing 230 for dispensing another type of fuel such as gasoline or diesel. In some embodiments, the electronics module 210 may be selected from a design that is compatible with fuel nozzle 222 for dispensing, for example, gasoline or diesel. Since gasoline and diesel dispensers are ubiquitous, such electronics module are readily available. By providing the sealed partition part 201 that seals the electronics module 210 from potentially hazardous conditions associated with nozzle 221 (such as vapors emitted therefrom), the electronics module 210 does not need to be specially designed or constructed to meet the requirements of such hazardous environment. In some embodiments, the partition part 201 separates CNG hydraulic components from the part of the dispenser that contains the electronics module 210.

(12) FIG. 3 shows the partition housing 201 including sealed partition part 202 in isolation. As shown, the partition housing 201 can have a shape that matches the shape of the dispenser system. In this embodiment, partition housing 201 has the shape of a coffin, e.g., with eight sides. In some embodiments, partition housing 201 can have a depth d in the range of 100 to 300 mm, and more preferably of about 200 mm, which is particularly useful for CNG dispenser applications. Partition housing 201 can have a solid volume. Alternatively, partition housing 201 can have a hollow core with left and right side walls that form an enclosed cavity, or with only one of the left and right side walls being present such that the partition housing 201 is open on one side only as shown. In some embodiments, partition housing 201 can be formed from or include a fire retardant material and/or a material that is impermeable to gas vapors (e.g., CNG, gasoline, diesel, etc.). The partition housing 201 can also be configured in different shapes and sizes depending on the dispenser system and the requirements.

(13) FIG. 4 shows yet another embodiment of a fuel dispenser system 400 that is similar to the system shown in FIG. 2, except that in this embodiment the system includes an additional nozzle 433 coupled to and seated in a third housing 430 provided between a partition housing 401 having a partition part 402 and an electronics module 410. To accommodate nozzle 433, partition part 402 is provided with a recess for receiving (at least partially) nozzle 433.

(14) FIG. 5 shows partition housing 401 including a partition part 402 of FIG. 4 in isolation. As can be seen, partition part 402 can be provided with multiple recesses to accommodate multiple nozzles (for example, one on each side of the system 400). In other embodiments, partition part 402 can have other shapes and/or sizes to accommodate different nozzles or to conform to the configuration of the dispenser system.

(15) In some embodiments, one or more components of the fuel dispensing system can be modular. For example, a nozzle can be part of a dispensing module, which can be replaced by another dispensing module to dispense, for example, a different type of fuel. The partition housing can also be configured as a module so that it can be, for example, interchanged with other modules. In some embodiments, a plurality of partition housings can be provided and arranged in different configurations. For example, in some embodiments, a plurality of partition parts can be placed next to each other in order to form a stronger and/or thicker barrier. In some embodiments, partition housings can be deployed on different sides of the electronics (e.g., one on each side) depending on the desired configuration.

(16) In some embodiments, the partition housing(s) can be added to existing gasoline and/or diesel dispensing systems to allow those systems to dispense natural gas (e.g., instead of or in addition to the previous fuel) without the need to replace some or all of the electronics.

(17) This written description uses examples to disclose the invention, including the best mode, and also to enable any person skilled in the art to practice the invention, including making and using any devices or systems and performing any incorporated methods. The patentable scope of the invention is defined by the claims, and may include other examples that occur to those skilled in the art. Such other examples are intended to be within the scope of the claims if they have structural elements that do not differ from the literal language of the claims, or if they include equivalent structural elements with insubstantial differences from the literal languages of the claims.
