DETAILED DESCRIPTION

[0095] For the purpose of providing an understanding of the principles of the disclosure, reference will now be made to the embodiments illustrated in the drawings and described in the following specification. It is understood that no limitation to the scope of the disclosure is thereby intended. It is further understood that this disclosure may include any alterations and modifications to the illustrated embodiments and includes further applications of the principles of the disclosure.

[0096] An electronic quick connect/disconnect system may be structured and formed in a variety of different ways. In one example, an electronic quick connect/disconnect system may be formed with an integrated external locking body or frame for receiving a male connecting member. In another example, an electronic quick connect/disconnect system may be formed with an internal locking body or frame.

[0097] The flow of electricity may be activated when an operator pushes an on/off switch to the on position and the flow of electricity may be broken when an on/off switch is pushed to the off position. The sensors may be located along or against the connecting coupling of the female connector and male connector, making an electrical connection between the various components.

[0098] In some embodiments, the electronic quick connect and disconnect coupling for forming a connection in a fluid system includes a first connector having a coupling end with a surface configured with at least one sensor portion thereof, and an attachment end adapted to be connected in fluid flow relationship to a fluid flow line; a second connector having a coupling end with a receiving opening to receive the coupling end of the first connector therein and having a surface configured with at least one sensor to sense the sensor of the coupling end of the first connector therein in a coupling condition only when the at least one sensor of the surface of the first coupling end communicates with the at least one sensor of the surface of the second receiving opening, and an attachment end adapted to be connected in fluid flow relationship to a fluid flow line; an electronic locking mechanism associated with and lockingly cooperable between the first connector and the second connector to secure the coupling end of the first connector in the receiving opening of the coupling end of the second connector when the coupling end of the first connector is inserted into and fully received in coupling condition in the receiving opening and to release the coupling end of the first connector from the receiving opening when desired to disconnect the first connector from the second connector; sensors on the first connector and the second connector cooperating to indicate when the connectors are in coupling condition, as the connectors are joined and moved into coupling condition, and as the connectors are released and separated from coupling condition; wherein the sensors on the first connector and the second connector include at least one sensor positioned on one of the first and second connectors and at least one sensor positioned on the other of the first and second connectors which senses the at least one sensor on the other when the connectors are in coupled condition; electronic circuitry; one or more user-operable controls which may include buttons, capacitive sensors, slide switches, an on/off switch, touch screens, and the like; a first circuit board assembled in or on the first connector and connected with the at least one sensor and the electronic circuitry and getting power from its own power supply or a second circuit board; a cover enclosing the first circuit board to protect the first circuit board; one or more electronic indicators disposed within second connector which may include electronic visual luminous indicators, electronic audible indicators, and electronic tactile indicators; a second circuit board getting power and grounding source from its own power source, the second circuit board comprising a system on chip, an IoT transmitter configured to transmit a message from the connector, and an IoT receiver, the at least one sensor electrically connected to the circuitry, the second circuit board electrically connected respectively to the at least one indicator and the at least one sensor; a cover enclosing the second circuit board to protect the second circuit board; a power supply configured to provide power to the second circuit board; the system on chip comprising a microcontroller, memory, a microprocessor or DSP cores, interfaces, wherein said microcontroller is configured to generate a message responsive to the current connection state of the first in relation to the second connector; wherein each indicator is configured to provide the message responsive to the microcontroller generating the message.

[0099] The system on chip (SoC) may be comprised of both hardware and software for controlling the microcontroller, microprocessor or DSP cores, peripherals and interfaces. The SoC and wireless communications chip may be integrated as a single-chip solution, specifically designed to support the speed, reliability, and quality requirements of the electronic quick connector.

[0100] The microcontroller may execute connector specific applications stored in the memory. The microcontroller may include digital signal controllers, analog-to-digital converters, digital-to-analog converters, and the like. The microcontroller may communicate with other elements of the connector over one or more communication busses. The transceiver may employ any communication protocol, including wired and wireless communication protocols. The wireless protocols may include Bluetooth, Bluetooth Low-Energy (BLE), Radio Frequency (RF), Wi-Fi, Digital Enhanced Cordless Telecommunications (DECT), cellular, near-field communications (NFC), ZigBee, Z-Wave, 6LowPAN, Thread, Sigfox and the like. The transmitter may employ multiple communication protocols. The user-operable controls may include buttons, capacitive sensors, slide switches, on/off switches, touch screens, and the like.

[0101] The sensors may include magnetic sensors, contact sensors, proximity sensors, limit sensors, and the like. A connector's sensors are electronic components whose purpose is to detect events or changes in a connector's configuration and relay the information to other electronics within the connector, such as the controller. Sensors may sense when two connectors are coupled or when they are decoupled. Sensors provided in the locking mechanism may sense when the locking mechanism is locked or unlocked. Sensors may be spaced circumferentially at certain degree intervals around a sensor ring.

[0102] Various sensors which may be used in various embodiments: contact sensors, which detect contact with another sensor; limit sensors, which detect when a subcomponent has moved to the end of its range; and magnetic sensors, such as Reed switches and Hall effect sensors, which use a magnetic field to close or open the circuit. The electrical circuit may be on when the magnet is near the sensor which occurs when the connector is in a connected position and, when the connector is in disconnected position, the sensor switch is off. Multiple sensors may be bundled together to ensure redundancy in case a sensor fails. Different types of sensors may also be bundled together. Sensors may immediately inform the microcontroller that a connection is coupled or decoupled via a signal. Sensors may be installed on the male connector, the female connector, or both. When a connection is made, the sensor signals to the controller that a connection event has occurred, and, similarly, when a connection is broken, the sensor signals to the controller that a disconnection event has occurred. In one embodiment of the disclosure, a controller can sense a partial connection, where multiple sensors may be aligned to sense partial connections. A partial connection may indicate to a user that a connector has been improperly coupled.

[0103] Hall effect sensors are one suitable technology for use with the electronic quick connect/disconnect connector. Hall effect sensors are semiconductor integrated circuits (ICs) with embedded Hall effect sensing elements are used all over the world in everyday products for measuring position. These magnetic sensor devices are used in personal electronics, industrial systems, medical devices, automobiles, aircraft, and spacecraft. Although there are other magnetic sensing technologies, Hall effect continues to be the most prevalent due to its unique set of advantages. First, they are inexpensive: ICs that incorporate Hall effect elements are mass produced with standard CMOS processing flows. Second, they are highly reliable. Being solid-state sensors that measure magnetic fields without requiring physical contact, devices can operate for decades. Third, they are simple: while the inside of an IC incorporates thousands of complex circuits, the outside of most devices only has 3 pins. The output pin is a simple indicator of the proximity to a magnet, and standard microcontrollers can directly read it. Fourth, they offer superior distance sensing: magnetic fields travel a distance and pass through most substances undisturbed. This allows sensors to be integrally located within connectors and are shielded from the environment and invisible to the user.

[0104] The connector system may use a proximity sensor which is a sensor able to detect the presence of nearby objects without any physical contact. A proximity sensor typically emits an electromagnetic field or a beam of electromagnetic radiation (infrared, for instance), and looks for changes in the field or return signal. The object being sensed is often referred to as the proximity sensor's target. Proximity sensors can have a high reliability and long functional life because of the absence of mechanical parts and lack of physical contact between sensor and the sensed object.

[0105] Sensors are used in electronic quick connectors to send signals to the microcontroller so that the microcontroller may instruct the transmitter to relay this information to other wireless devices and apps and to instruct indicators to relay this information to a user. With modern advances in system-on-chip microcontroller platforms and communication components, the use of sensors may be easily applied into the field of quick connectors for fluid systems.

[0106] The sensor's compact size may be powered by one or more 3VDC+ lithium batteries and employ crystal technology for signal transmission, with a longer battery life than non-lithium batteries. The microcontroller may also utilize learn mode technology, enabling it to work with other systems. Each connector is given a unique identification code at the factory, which makes it possible to register connectors with base stations, different controllers, other devices, and apps. The connectors may transmit using beacon technology, which means a battery and sensor status signal can frequently be transmitted.

[0107] The information may be made useful to a user in some way. This could be in the form of a visual indicator, an audible indicator, a tactile indicator, or even an alert to the user, such as email, text, or notification via an app. For example, a simple text alert could be sent when a coupler system is disconnected. Additionally, an interface allows users to proactively check in on one or more connectors. Depending on the application, the user may also be able to perform an action and affect the system. For example, the user might remotely adjust an electronic valve opening via an app on their phone using existing wireless valve technology. Some actions may be performed automatically. Rather than waiting for a user to electronically adjust the flow, a system could adjust the flow automatically via predefined rules.

[0108] In one embodiment, an electronic connector sends data to a solid-state base station controller mounted inside a cabinet. The cabinet contains a power supply to distribute power in the cabinet; a detector interface component, to connect to electronic connectors and other controllers; amplifiers (such as Wi-Fi repeaters); the controller itself; a monitor unit; and other components. Battery backups may be installed in a separate cabinet from the controller cabinet. These may also provide battery recharging capabilities to the connectors where the operator recharges the connectors when not in use. Solar panels may be installed on the cabinet for recharging the batteries. The base station receives data from the connectors that inform the controller processor whether connectors are connected or disconnected, so that it can display to and alert operators of any disconnections.

[0109] The base station can seamlessly integrate connector data from diverse connector systems, devices and sensors from multiple manufacturers and models. The base station controller is aimed at operators wishing to receive data from the connectors into applications. Data can be collected from a number of locally connected physical devices and sensors. The base station can also be a component of an electronic spigot system. The base station may also provide a charging unit for a plurality of electronic connectors.

[0110] Various embodiments provide an electronic quick connect and quick disconnect system which is compact, replaces the conventional connector, and notifies operators of the current connection state. A base station, housed within another irrigation controller, such as an electronic spigot, can provide a fail-safe mechanism which automatically shuts off electronically controlled valves whenever the system detects a disconnection of one or more electronic connectors in the fluid system.

[0111] Turning now to the figures, FIGS. 1A to 1D and 2 illustrate the flexibility and usefulness of an electronic quick connect/disconnect system 10 in accordance with one or more of the herein described embodiments. The system 10 provides easy connection and disconnection and easy detection mechanisms to indicate whether a connector is connected or disconnected. A fluid dispensing device can be a nozzle 12, a hose 14, a sprinkler 16, an oscillator 18, a wand 20, a faucet 22, a showerhead 24, a spigot 25, a hose to hose configuration (not shown), other hose attachments, a fluid source 27 for non-garden devices, or combinations thereof. Many other examples of devices are possible. The fluid dispensing device or source may be electronic, and the system can utilize the power supply of the dispensing device or fluid source.

[0112] As depicted in FIG. 2, the system 10 includes an electronic female connecting member 30 and a male connecting member 40 interconnected to the electronic female connecting member, eliminating the need for a separate coupler or an adaptor. An electronic indicator assembly may be implemented or integrated into at least one of the connecting members 30, 40. An electronic sensor ring assembly may be implemented or integrated into at least one of the connecting members 30,40. A locking member may be implemented or integrated into one of the connecting members 30, 40. Several locking members will be described in greater detail below.

[0113] In one example, a connecting end of the female connecting member 30 is coupled to the nozzle 12 and a connecting end of the male connecting member 40 is coupled to the hose 14, and vice versa. In another example, the connecting end of the female connecting member 30 is coupled to a sprinkler (not shown). It will be understood that certain combinations and subcombinations are of utility and may be employed without reference to other features and subcombinations. For example, a hose to hose system may use an electronic connector.

[0114] As depicted in FIG. 2A, a female connecting member 30 couples with a male connector 40, in one embodiment. FIG. 2B is a practical application of the electronic connector, as shown in FIG. 2A, where the female connecting member 30 is coupled to a spigot, and the male connecting member is connected to a garden hose. The electronic aspects of the connector indicate to a user that a connector system is coupled or de-coupled.

The microcontroller 608 may include digital signal controllers, analog-to-digital converters, digital-to-analog converters, and the like. The microcontroller 608 may communicate with other elements of the connector 600 over one or more communication busses 630. The transmitter 612 and receiver 614 which are the communication components of an IoT (or wireless) chip may employ any communication protocol, including wired and wireless communication protocols. The transmitter 612 may employ multiple communication protocols. The user-operable controls 620 may include buttons, capacitive sensors, slide switches, on/off switches, touch screens, and the like. The visual indicator 616 may be comprised of multiple luminous elements. The audible indicator 617 and tactile indicator 618 may also provide an electronic means for indicating a proper coupling.

[0116] FIG. 2C shows elements of a connector 600 according to one embodiment. Although in the described embodiment elements of the connector 600 are presented in one arrangement, other embodiments may feature other arrangements. For example, various embodiments may lack one or more of the features shown, such as a connector system which does not provide audible and tactile feedback. In addition, elements of the connector 600 may be implemented in hardware, software, or combinations thereof.

[0117] Referring to FIG. 2C, the connector 600 may include one or more each of sensor(s) 602, electric motor(s) 604 and valve(s) 605, a microcontroller 608, a memory 610, a transmitter 612, a receiver 614, one or more user-operable controls 620, and a power supply 626. The connector 600 may include other elements as well. The elements of connector 600 may receive power from the power supply 626 over one or more power circuitry 628. Various elements of the connector 600 may be implemented as one or more integrated circuits. As described in U.S. non-provisional application Ser.

[0123] Female connector 30 comprises an externally threaded portion 71 forming an attachment end integrally connected to a female quick connect portion or end 74 by means of a shoulder portion 77. Female connector 30 further includes a water channel 80 which extends completely through female connector 30, a plurality of tapered objects (such as a ball, pin, tab, or the like) retaining holes 83 through female portion 74, an internal annular O-ring groove 86 inside shoulder portion 77, an external annular O-ring groove 89 about externally threaded portion 71 adjacent shoulder portion 77, a ring-shaped surface 92 about shoulder portion 77, and a pair of electronic sensors 95 and 98 formed in female portion 74 by a notch 100 therein.

The luminous element ring 150 is electronically connected with a control pin of the system-on-chip controller. The luminous element ring 150 may include a plurality of light emitting diodes, a semiconductor laser (not shown) or other electronic components (not shown) which can emit light. The luminous element ring includes an annular translucent cover 151. Female connector 30 is preferably made of brass or stainless steel, but can be made of aluminum, brass, stainless steel, plastic, polymer, thermoplastic, or of any similar material.

[0124] Sleeve 29 is preferably made of brass or stainless steel, but can be made of aluminum, brass, stainless steel, plastic, polymer, thermoplastic, or of any similar material.

[0125] Lock ring 35 is secured in ring-shaped lock ring groove 112 during assembly after sleeve 29 is slid over female coupling portion 74 with objects 44 in holes 83.

[0126] Compression spring 32 biases sleeve 29 against lock ring 35 and comprises a piece of cylindrical metal wound approximately two turns at such a radius as to closely fit about female portion 74 of female connector 30. Spring 32 is preferably made of stainless steel.

[0127] Lock ring 35, O-rings 38 and 41, and retaining balls 44 are of standard construction known in the fluid flow industry, and disclosed in prior art, as is the construction of object retaining holes 83 to retain balls 44 therein.

[0128] The circuit board which consists of the SoC, the memory unit, and the IoT communications chip (transceiver) are derived from standard technology known in the electronics industries, as is the power switch, the power supply, and the electronic circuitry.

In such a coupled condition, male and female connectors 40 and 30 are electronically or magnetically connected to each other.

[0130] When male and female connectors 40 and 30 are connected, sensors 95 and 98 in female connector sense that the female connector is connected to the male connector. For example, sensors detect each other, and when the voltage difference exceeds a set value of the controller, a control signal is emitted from a control pin of the chip to make the luminous element illuminate with an indication of a connected state. A control signal may also be emitted to make an audible indicator or tactile indicator produce indications responsive to the signal received. Furthermore, the transmitter sends a connected state message to the wireless network.

[0131] The indicator assembly, the circuit board, the embedded circuitry, the sensor assembly, and the connector may utilize one or multiple layers.

[0132] FIGS. 5 and 6 illustrate another embodiment of a quick connect/disconnect system 10. FIGS. 5 and 6 are similar in engineering and construction to the system 10 in FIGS. 3 and 4 and like elements are identified with a like reference numbering convention. In this embodiment, the system 10 includes an electronic valve component 200 as described above and allows fluid to flow through. Any sort of electronic valve 200 may be used.

[0133] FIGS. 7A to 7C show a plurality of electronic sprinkler applications (as described in U.S. non-provisional application 15/276,874) for electronic quick connector 10. In FIGS. 7A to 7C is shown an electronic sprinkler 113 comprising a base 116 with respective male and female hose couplings and for connection to standard hoses (not shown), an electronic sprinkler head 125, an extension tube (or riser) 155, and quick coupling 10 and quick coupling 10. One of male and female electronic connectors 40 and 30 is threadably connected to base 116 and the other to electronic sprinkler head 125 such that electronic sprinkler head 125 is quickly connectable to base 116. The extension tube (or riser) 155 extends the overall electronic sprinkler's height and interconnects the respective male and female connectors 40 and 30 with electronic sprinkler head 125 and the respective male and female connectors 40 and 30 with base 116.

[0134] In FIG. 7B is shown a lawn sprinkler 128 comprising a base 116, a sprinkler head 131, and quick coupling 10. Sprinkler 113 can be configured to be sprinkler 128 simply by uncoupling male and female connectors 40 and 30 of quick coupling 10 and interchanging sprayer 131 with sprayer 125, each having a respective male or female connector 40 and 26.

[0135] In FIG. 7C is shown a sprinkler 134 comprising a base 137 with respective male and female hose couplings 119 and 122, a sprinkler head 140, and quick coupling 10. In FIG. 6 is shown a sprinkler 143 comprising a base 146 with a female hose coupling 122, a sprinkler head 149, and quick coupling 10.

[0136] FIGS. 8A to 8B show an electronic spigot for electronic quick connectors 10 and 10. In FIGS. 8A to 8B, it is shown an electronic spigot 113 comprising a base 116 with respective male and female hose couplings 119 and 122 for connection to standard hoses (not shown), an electronic spigot 125, a cylindrical extension tube 155, quick connectors 10 and 10. One of male and female electronic connectors 40 and 30 is threadably connected to base 116 and the other to tube such that electronic spigot 125 is quickly connectable to tube 155. The extension cylindrical tube 155 extends the overall electronic sprinkler's height and interconnects the respective male and female connectors 40 and 30 with electronic spigot 125. If an operator wishes to connect a hose directly to the electronic spigot, one of male and female electronic connectors 40 and 30 is threadably connected to hose and the other to spigot such that electronic spigot 125 is quickly connectable to hose.

[0137] Referring to 8A to 8D, the electronic spigot further comprises a communications module for receiving notifications/alerts received from quick connectors. The communications module is installed within the body of the base station.

[0138] As shown in FIGS. 8A to 8D, the base post is connected to the body. The spigot controls the valve(s) to open or close, thus starting, stopping, and variably controlling the water supply (e.g. level of water flow) of the spigot. The valves can be provided as any suitable electronical or mechanical actuatable device (e.g., a solenoid variable force controlled valve) that controls the flow of fluids. The post can be of any geometrical shape, such as cylindrical, rectangular, bollard, or the like. The post can be as simple as a plain post or can have controls flush or surface mounted, where the main body is housed within the post. The surface mounted or recessed mounted base allows for an installer to place the electronic spigot/base controller in the most convenient location, thus eliminating the need for longer hoses, etc.

[0139] As generally illustrated, the electronic spigot is typically provided as a specific purpose computing device located within a geographical area of electronic connectors. When organized into groups within a particular area (e.g., a residential landscape), hoses coupled to particular valves define a watering zone (also referred to simply as a zone) within the particular area. In some embodiments, map-based display functionality may be present, enabling a user to view electronic connectors associated with the electronic base station controller in a map-based format.

[0140] The input unit for controlling the base station comprises a user interface adapted to be engaged by a user, thereby enabling the user to receive signals from the quick connectors registered with the base station controller.

[0141] The connecting ends of the connecting members 30, 40 are shown in detail in FIG. 9-12. The female connecting member 30 includes a female tubular sleeve 32 and a connector 36. A plurality of sensors (shown as a ring assembly 36a) communicating with the sensors in the male connecting member may be provided as an outer ring assembly 36a. The power button 32 activates the power of the connector. If a certain time has passed, for example, 10 seconds, without any further connection/disconnection activity, the electronics may be powered to an off, standby or sleep state.

[0142] The luminous ring 37 comprised of light emitting diodes, lens cover, and integrated circuitry emits flashing or steady light to indicate to the user that status of a connection.

[0143] The connector 36 includes at least one sensor and is illustrated as a sensor ring assembly 36a. When the male connector is inserted into the interior of the connector 36, the sensor ring of the male connector contacts a sensor ring 36a housed within the outward facing wall of the female connector.

[0144] A connecting end of the connector 36 is sized to be substantially conformed to an outer receiving threaded surface of a fluid dispensing device or source. As an example, the connector is a nozzle, sprinkler, or hose connector 36, as illustrated in FIG. 12. FIG. 12 are similar in engineering and construction to the connector in FIGS. 9-11 and like elements are identified with a like reference numbering convention.

[0145] The connector may utilize one or multiple layers. The connector may be made of aluminum, brass, titanium, stainless steel, plastic, polymer, thermoplastic, or of any similar material. The indicator assembly of the present disclosure may utilize one or multiple layers. The indicator assembly may be made of aluminum, brass, titanium, stainless steel, plastic, polymer, thermoplastic, or of any similar material. The sensor assembly of the present disclosure may also utilize one or multiple layers. The sensor assembly may be made of aluminum, brass, titanium, stainless steel, plastic, polymer, thermoplastic, or of any similar material.

[0146] Although the system 10 shown as two connectors 30, 40 separately coupled to the fluid dispensing devices, it should be understood that numerous variations to the configuration of the system are possible. For instance, the connector 36 may be formed as part of or integrated into one of the connecting members 30, 40. In another example, at least one of the connecting members 30, 40 may be formed as part of or integrated into the fluid dispensing device.

[0147] In many of these embodiments, a system 1100 includes a first assembly 1102 and a second assembly 1160. As illustrated in FIG. 13, the first assembly 1102 includes a connector 1104 having a connector end 1106 for receiving a nozzle, for instance. The connector 1104 further includes a passageway and sensors formed on an outer wall of connector 1104. An optical sensor, contact sensor, limit sensor, and the like may be integrated into the system to signal when the system is in connected position. In this embodiment, the system 1100 provides for a larger cylinder within the assemblies 1102, 1160 and allows fluid to flow through and accommodates a larger power supply and electronics.

[0148] FIG. 14 illustrates another embodiment of a quick connect/disconnect system 1100. FIG. 14 is similar in engineering and construction to the system 1100 in FIG. 13 and like elements are identified with a like reference numbering convention. The locking structure may be integrated into the system, such as the first housing, second housing, or the locking member. The indicator assembly may be integrated into the system, such as the first housing, second housing or as a separate indicator member. Similarly, the sensor assembly may be integrated into the system, such as the coupling portion of the connector, or as a separate sensor assembly member. In this embodiment, the system 1100 provides for a larger cylinder within the assemblies 1102, 1160 and allows fluid to flow through and accommodates a larger power supply and additional electronics. The locking structure may further have at least one sensor to detect when the coupler is in a locked condition.

[0149] FIG. 15 illustrates another embodiment of a quick connect/disconnect system 1100. In this embodiment, the system 1100 includes a larger cylinder within the assemblies 1102, 1160 and allows fluid to flow through and accommodates a larger power supply and electronics.

[0150] FIGS. 16A-16B illustrate another embodiment of a quick connect/disconnect system 10. FIGS. 16A-16B are similar in engineering and construction to the system 1100 in FIGS. 3-4 and like elements are identified with a like reference numbering convention. A plurality of sensors 98, 98 is housed within the female connector and a plurality of sensors 68, 68 is housed within the male connector. Each sensor provides a detection mechanism between itself and an external connector, so that the system can determine the proximity of an external connector in relation to itself. This is useful for detecting partial connections and indicating the connection state as a series of indications.

[0151] FIG. 17 is a cross-sectional view of the main body 40 of the quick connect/disconnect system's female connector of FIG. 2 including a first and second plan view, first and second end views. The sensor ring is integrated into the connector.

[0152] As shown in FIG. 18, a fluid system 100 includes a nozzle 102, a first electronic quick connect/disconnect system, shown as a first coupler system 104, a second electronic quick connect/disconnect system, shown as a second coupler system 106, and a spigot 108. A fluid conduit, shown as a hose 110, connects the first coupler system 104 to the second coupler system 106.

[0153] The nozzle 102 is an example of a fluid device that includes a body 116, a valve, and a shaft. The nozzle 102 is representative of any fluid device, such as fluid sprinklers, wands, faucets, electronic or mechanical timers, tanks, containers, accessories, garden wheel reels, and any other fluid device.

[0154] In FIG. 18, the coupler system 104 is connected to the nozzle 102 and to the hose 110. The coupler system 104 includes a male connector 132 and a female connector 134. The male connector 132 is connected to the nozzle 102 and is shown as being connected to the female connector 134. In another embodiment, the fluid device 102 is configured to connect to the female connector 134. As illustrated in FIG. 18, both the male connector 132 and the female connector 134 contains sensors, that as a system signal to the controller whether the two connectors are coupled.

[0155] As shown in FIG. 19, the connector 142 is substantially circular and includes a first sensor 152 and an opposite second sensor 154. The sensors 152, 154 are configured to contact the corresponding sensors of another connector (not shown).

[0156] The tube coupling portion is a cylinder that defines an axial center. The tube coupling portion defines an inside diameter and an outside diameter. The diameters are typically approximately constant along a length of the tube coupling portion, and an outer surface of the tube coupling portion is free from irregularities, however, the diameters may change along the length of the tube coupling portion. In another embodiment, instead of being cylindrical, the tube coupling portion defines a cross section that is elliptical, triangular, square, rectangular, pentagonal, hexagonal, semi-cylindrical, or any other shape as desired. In any components of the system 100 as described herein, similar geometry may be used or applied, including components in the system as depicted in FIG. 2.

[0157] The body portion may be formed from stainless steel, brass, aluminum, die cast aluminum, zinc die cast, titanium, polypropylene, thermoplastic, or any other material desired that is suitable for the type of fluid selected to pass through the fluid channel. Furthermore, in some embodiments the body portion is one or more of anodized, chromed, painted, hardened, and any other method that is suitable for the body portion.

[0158] In operation, the fluid system 100 is configured to perform a method shown in FIG. 20, which includes a method of powering on the circuitry, coupling the connectors to one other, and connecting to an IoT network for transmitting and receiving messages.

[0159] With reference to FIG. 21, the fluid system 100 is shown partially disconnected, with the spigot 108 disconnected from the female connector 422, the male connector 420 disconnected from the male connector 420, and the female connector 134 disconnected from the male connector 132. The fluid system 100 is shown partially disconnected since the male connector 132 is shown, in this example, as being connected to the nozzle 102.

[0160] Feedback from Electronic Connectors when Connected

[0161] When the male connector 132 is connected to the female connector 134, one or more luminous elements emit light and alert the user that a connection has been established between the male connector 132 and the female connector 134. When the connection occurs, a sound and/or vibration, as tactile feedback, may also be provided to further alert the user that a connection has been established between the male connector 132 and the female connector 134.

[0162] When at least one sensor senses a connection, the controller is signaled. In several embodiments, the at least one sensor of either the first connector or the second connector sense that the connectors are coupled. A control signal is emitted from a control pin of the controller chip to make one or more luminous element illuminate according to a set mode of operation. Furthermore, the transmitter transmits a signal or message to a base station, another device, or app.

[0163] Feedback from Electronic Connectors when Disconnected

[0164] When usage of the nozzle 102 is complete either to store the nozzle or to replace the nozzle with another device, the user disconnects the nozzle from the hose 110 by disconnecting the male connector 132 from the female connector 134. The male connector 132 is moved away from the female connector 134 and the connectors are separated.

[0165] When the sensors detect that the connectors are separated or disconnected, the controller is signaled. A control signal may be emitted from a control pin of the chip to make one or more the elements illuminate according to a set mode of operation. Furthermore, the transmitter sends a signal or message to a base station, another device, or app.

[0166] Advantages of the Electronic Quick Connect/Disconnect Connector

[0167] The electronic connector system 100 offers numerous other advantages. First, users can quickly and easily disconnect a fluid device, such as the nozzle 102, from the hose 100. Second, the male connector 132, 420 and the female connector 134, 422 are quickly and easily connected and disconnected from each other. As illustrated in FIG. 18 and FIG. 21, the locking assembly of the male connector 132, 420 is designed to quickly connect/disconnect the connectors 132, 134, 420, 422, thereby making the connectors easy to operate. The locking assembly may be engineered and constructed differently, however, the electronic quick connector system offers a quick, easy, and convenient approach for connecting a fluid conductor to a fluid source while offering a reliable verification mechanism of physical connections.

[0168] When the male connector 132, 420 is connected to the female connector 134, 422 the body portion 136, 426 can either be rotatable or fixed relative to the female connector and the hose 110, using various methods employed in the industry today. Accordingly, when the male connector 132 is connected to the female connector and to the nozzle 102, the nozzle is rotatable relative to the hose 110. A switch can offer a method for switching between rotatable and non-rotatable positions.

[0169] As another advantage, when the male connector 132, 420 is connected to the female connector 134, 422, one or more luminous elements emit light in a steady or flashing mode of operation. Furthermore, the transmitter sends a signal or message to a base station, another device or app. Similarly, when the male connector 132, 420 is disconnected to the female connector 134, 422, one or more luminous elements may emit light, while the transmitter may send a signal or message to a base station controller, another device or app. In some embodiments, the female connector may have a test the state, which, in turn, the controller sends a message to a visual indicator to emit light reflecting the current connection state, and to the transmitter to send a signal or message to a base station controller, another device, or app. In other embodiments, the connector may act as a beacon, frequently emitting the current connection state of the connector and
