In the drawings:
Referring now to the discussion that follows and also to the drawings, illustrative approaches to the disclosed systems and methods are shown in detail. Although the drawings represent some possible approaches, the drawings are not necessarily to scale and certain features may be exaggerated, removed, or partially sectioned to better illustrate and explain the present invention. Further, the descriptions set forth herein are not intended to be exhaustive or to otherwise limit or restrict the claims to the precise forms and configurations shown in the drawings and disclosed in the following detailed description.
The drawings and the following detailed description relate generally to systems of substance communication coupling systems for coupling a substance provider with a substance consumer. The following definitions apply to terms that may be used in the specification and the claims, unless otherwise noted.
As used herein, a “substance” is a material that may be communicated from one device to another. A substance may include a gas, a liquid, or a solid, or any combination thereof. Examples of substances include, but are not limited to, liquid soap, powdered soap, compressed air, tablets, caplets, water, ice cubes, and a beverage.
As used herein, “substance communication” or a “substance communication service” is a useful provision of a substance from one device to another device. Communicating a substance includes supplying or receiving a substance. As used herein, communication of substance includes both uni-directional and multi-directional communication between any two devices, either directly or through an adapter, as defined herein. Substance communication may be provided in quanta, such as capsules or other doses of substances, batches of discrete items such as tablets, or consumable components.
The terms “provide” and “supply” and any variation thereof, are used herein to denote a source of the substance relative to a device receiving the substance. Neither term is limited to the original source of the substance. A device that provides or supplies the substance may simply be passing on the substance from the original source. For example, a device that provides water may pass on water it receives from a residential water supply. However, the device may alternatively or additionally provide another substance that originates with the device, such as an additive stored in a reservoir.
The term “receive” and any variation thereof, is used herein to denote receipt of the substance relative to the device providing the substance. The term is not limited to the ultimate consumer of the substance. A device that receives a substance may simply be passing on the substance from the source, such as an appliance, to a device that will consume, as hereinafter defined, the substance. The device which receives a substance is not necessarily the end consumer of the substance.
The term “consume” and any variation thereof, as used herein, denotes the act of employing or dispensing at least a portion of the substance received in connection with performing a function.
The term “consumable” and any variation thereof, as used herein, includes any substance that may be consumed by a host, an accessory device, or a user person, such as food, cosmetics, or medicine. The consumable may, for example, be a substance that is used up and must be replenished for subsequent cycles of operation. For a clothes washer, the consumable might be a detergent and/or a softener. For a clothes dryer, the consumable might be an anti-static cloth. For a cooking or refrigeration appliance, the consumable may actually be the article on which the appliance performs its cycle of operation, as in the case of food, later to be consumed by a person. More specific examples of the use of a consumable in appliances include dispensing additives for clothes washers, clothes dryers, or combination washer/dryer appliances. The additives can include, but are not limited to, normal detergents, gentle detergents, dark clothing detergents, cold water detergents, fabric softeners, chlorine bleaches, color-safe bleaches, and fabric enhancement chemistry. Non-limiting examples of fabric enhancers are additives to provide stain resistance, wrinkle resistance, water repellency, insect repellency, color fastness, fragrances, and anti-microbials. Another example of a consumable is the filters used by an appliance. Refrigerators, dryers, washers, and dishwashers are all known to use filters that are consumed in the sense that they wear out and must be replaced.
The term “coupled” and any variation thereof, as used herein, includes any type of connection that permits transfer of a substance between two devices. The term “coupled” does not require a physical connection between the two devices, so long as the coupling permits transfer of a substance. The term “coupled” includes both fixed and removable coupling, as well as both continuous and intermittent coupling.
A “service connector system” is a connector system having at least two separate service connector components, also referred to as service couplers, each associated with a useful device. The service connector components cooperate with one another to couple the useful devices to facilitate communication of a service between the useful devices. A service connector system may carry multiple services. An electromagnetic service connector system, for example, may be associated with or incorporated into a substance connector system or may be independent of a substance connector system but be associated with the same substance holder, substance provider or substance consumer.
The term “useful device” and any variation thereof, as used herein, is a device that is capable of performing a useful physical or virtual function either alone or in combination with another device.
The term “substance consumer” and any variation thereof, as used herein, is any useful device that employs, uses, stores, or dispenses a substance in connection with performing a physical or virtual function. A substance consumer may be, for example, a smart utensil, an appliance, a resource controller, such as a water controller, a dispenser, a filter, a water filter, an air filter, a detergent dispenser, a drink dispenser, a detergent cartridge, and a substance holder, such as a bottle, a jug, or a cycle accessory.
The term “substance provider” and any variation thereof, as used herein, is any device that is capable of providing or supplying a substance to another device.
A “substance communicating device” is any substance holder, substance provider or substance consumer that is capable of communicating substance with another device.
A “substance communicating system” is any combination of substance communicating devices capable of communicating a substance therebetween.
As used herein, the term “substance holder” is anything that holds or contains a substance, which may include, but is not limited to, a container, a dispenser, a cartridge, a dish, a bag, or a carton.
As used herein, the term “consumable holder” is any substance holder that holds or contains a consumable.
As used herein, the term “host” is an apparatus that has a primary function independent of providing or receiving a substance. A host may be a substance provider, a substance consumer, or both. For example, the host may be an appliance and the primary function can be performing a series of steps to conduct a useful cycle of operation. The appliance may be a conventional household appliance, such as a refrigerator performing a cooling cycle or an ice making cycle. Other examples of appliances that may be hosts include, but are not limited to, a freezer, a conventional oven, a microwave oven, a dishwashing machine, a stove, a range, an air conditioner, a dehumidifier, a clothes washing machine, a clothes dryer, a clothes refreshing machine, and a non-aqueous washing apparatus, or any combination thereof. Alternatively, the host may be a fixture such as a water softener, a water heater, a furnace, pool water treatment equipment, or an HVAC system. The host may be a small device such as a thermostat, a blender, a mixer, a toaster, a coffee maker, a trash compactor, an air purifier, an iron, a vacuum cleaner, or a robot. The host may alternatively comprise a structural feature of a building, such as a wall, a cabinet, or a door. The host may also provide other services, such as electrical power, electronic data, mechanical power, illumination, heat, or sound.
As used herein, the terms “accessory” or an “accessory device” refer to any useful device which may be coupled to a host and communicate a substance to or from the host. An accessory device may be used primarily in conjunction with a host to enhance, supplement, regulate, or monitor the functionality of the host or may have independent functionality and utility. An accessory device may be a substance provider, a substance consumer, or both. An accessory device may be a substance holder or a consumable holder. Examples of an accessory device include, but are not limited to, a paper product dispenser, a dry goods dispenser, a bottle opener, a liquid dispenser, a pill dispenser, a water dispenser, a fan, a motor, a tissue dispenser, a can opener, a mixer, a blender, an ice dispenser, an ice maker, an ice cream maker, a coffee maker, a soap dispenser, and a softener dispenser. An accessory or accessory device may also communicate electromagnetic service with the host.
As used herein, the term “portable device” is an accessory device that is designed to be moveable by a user during its useful life between a use location and a storage location or alternative use location.
As used herein, the term “independent device” is a useful device that provides a useful function without being connected to a substance provider. In some cases the primary function of the independent device is different from the primary function of a host from which the independent device may receive a substance. The independent device may be an accessory device.
As used herein, the term “dependent device” is a useful device that provides a useful function only when connected to a substance provider. A dependent device may be a substance consumer. Examples of a dependent device that may be coupled to a host include, but are not limited to, a smart pan or pot, an ice maker, and a bulk detergent dispenser.
As used herein, the term “substance communication coupling system” or “substance connector system” refers to any connector system having at least two separate substance communicating connector components, each of which is associated with a useful device. The substance communicating connector components cooperate with one another to couple the useful devices to facilitate communication of a substance between the useful devices.
As used herein, the term “switched substance communication coupling system” is a substance communication coupling system having switching or valving capability in at least one of the substance communicating connector components operable to selectively control the communication of a substance between the components of the substance communication coupling system.
As used herein, the term “substance switch” is any component used to selectively regulate the communication of a substance between components of a substance communication coupling system, such as switches, valves, pumps, fans, and controllers for controlling such devices. A substance switch may be associated with more than one type of service. For example, a substance switch may be associated with, integrated with, or comprise an electromagnetic switch or may be independent of the electromagnetic switch.
As used herein, the term “switching valve” is any valve used to selectively facilitate the communication of a substance between components of a substance communication coupling system.
“Wireless” refers to a type of communication in which power and/or data is transferred over a distance without the use of electrical conductors or wires. For example, electromagnetic waves, light waves, or acoustic waves can be used to carry power and/or data over a distance without using electrical conductors or wires.
A “proximity target” as used herein is any component or device that may be detected when positioned within a predetermined distance of an associated proximity sensor, defined below. A proximity target may be passive, such as a visual target or a magnetic target formed of magnetic or magnetic responsive material. Other examples of passive proximity targets may include a conductive component or surface capable of cooperating with a magnetic field, a current, or a voltage provided by a proximity sensor. A proximity target may alternatively be active or powered such as an electromagnet, a generator of a magnetic field, a current, a voltage or an acoustic wave. An active proximity target may alternatively provide a powered readable display or dispense a detectable chemical.
A “proximity sensor” as used herein is any component or device that may detect an associated proximity target when the proximity target is within a predetermined distance of the proximity sensor. A proximity sensor may detect, for example, a change in an electromagnetic field, an electromagnetic wave, an acoustic wave, a visual target, a chemical component, an electrical signal, a change in voltage, a change in current, a change in frequency, a change in resistance, a change in inductance, a change in capacitance, a mechanical signal, a change in pressure, a displacement, a vibration, and the presence of a chemical, A proximity sensor may be active or passive, such as a magnetic sensor of magnetic or magnet responsive material, or may alternatively be active. Examples of active sensors include active magnetic sensors, light sensors, optical sensors, acoustic sensors, electromagnetic sensors, chemical sensors and thermal sensors. Examples of magnetic sensors include magnets and magnetic responsive components. Examples of optical sensors include infrared sensors, photoelectric sensors, fiber optic sensors, photo resistors, photovoltaic sensors, photo diodes and cameras. Examples of electromagnetic sensors include radio receivers, radar sensors, Hall Effect sensors, inductive sensors, capacitive sensors, variable reluctance sensors and eddy current sensors. Examples of acoustic sensors include ultrasonic sensors and microphones. A contact proximity sensor detects a proximity target by touching the proximity target. A contactless proximity sensor detects the proximity target through a wireless or contactless means. For example, magnetic flux can be used as the signaling mechanism between a contactless proximity sensor and a contactless proximity target.
As used herein, the term “proximity system” is a system that uses a “proximity switch” operated by a plurality of “proximity coupling components,” each associated with a different parent device, for determining that the parent devices are in proximity with each other. Parent devices are usually paired, examples of which include a service provide and a service consumer, a host and an accessory device, and a host and an adapter. Proximity coupling components may include a proximity target associated with one parent device to actively or passively provide an indication of the presence of the one parent device and a proximity sensor associated with the other parent device that is responsive to the presence of the proximity target to activate the proximity switch. The proximity switch may be used to provide a signal or message indicative of the proximity of two parent devices or may directly or indirectly regulate the flow of a service along a service line. The systems disclosed herein employ contactless proximity systems, wherein the proximity target and proximity switch use contactless or wireless means to detect the proximity of the two parent devices.
As used herein, the term “plug” is a generally male substance connection component.
As used herein, the term “receptacle” is a generally female substance connection component.
As used herein, the terms “substance line” or “substance pathway” refer to a pathway for transferring a substance from one location to another. The substance line may have any of a variety of configurations depending on the type of substance being transferred, including, but not limited to, a pipe, a conduit, a tube, a channel, or fludically-aligned supply and receiver ports with a gap therebetween. It will be appreciated that the substance line or pathway may comprise a gap across which the substance is directed by gravity, magnetism, electrical induction, heat radiation or other field.
As used herein, the term “adapter” is an intermediate device that may be provided between a first and second useful device, such as between a host and an accessory, to facilitate the communication of substances between the first and second useful devices. An adapter may receive a substance from the first useful device and provide the substance or a modified version of the substance to the second useful device, for example, by providing a substance dispensing through a metering process, by processing the substance, or by combining the substance with an additive. In some applications, multiple adapters may be interposed between two useful devices. In other applications, three or more useful devices may be coupled to a single adapter, such as multiple accessories for a host. In some applications, the adapter may itself be a useful device providing a useful function not provided by the other useful device or devices coupled to it. An adapter may optionally include a transformative component that transforms a service from a service provider to a different service, which is supplied to a service consumer. This may be useful when the service from the service provider is not compatible with the service consumer. The transformative component can be configured to transform the service into a compatible form for the service consumer. Examples of transformative components are protocol converters, power transformers, or other devices that convert substance, energy, or data from a first form to a second form.
As used herein, the term “functional unit” is the combination of any adapter coupled to an accessory, which together provide functionality that neither the adapter nor the accessory can alone provide. Any functional unit itself is also included within the meaning of the term “useful device”. In some cases, it is contemplated that a dependent device may be coupled with an adapter that provides one or more services required by the dependent device to enable the functional unit to provide a useful function, in which case the functional unit also constitutes an independent device.
Referring to
Accessory device 14 may be either directly or indirectly coupled to host 12. Direct coupling occurs when accessory device 14 includes a substance communication coupling system suitably configured for engaging a corresponding substance communication coupling system of host 12 to establish a pathway for transferring a substance between the host 12 and the accessory device 14. The substance pathway provides a line for transferring at least one substance from host 12 to accessory device 14 and from accessory device 14 to host 12.
An adapter 16 can be provided for coupling a second accessory device 18 having an incompatible substance communication coupling system to host 12. A substance communication coupling system is incompatible if it cannot be directly coupled to a corresponding substance communication coupling system, such as when the incompatible substance communication coupling system lacks certain physical features that would enable the substance communication coupling system to engage the corresponding coupling system to establish a substance pathway. Adapter 16 may include a substance communication coupling system that can be directly coupled with the substance communication coupling system of host 12 and a second substance communication coupling system that can be directly coupled with the incompatible substance communication coupling system of accessory device 18, thereby establishing a substance pathway between host 12 and accessory device 18.
Although accessory device 14 is shown coupled to an upper surface of host 12, whereas accessory device 18 is shown attached to a front surface of host 12 by way of adapter 16, it shall be appreciated that in practice, accessory device 14 and adapter 16 may be suitably configured for coupling to host 12 in any desired location and manner in order to accommodate the design and performance requirements of a particular application. For example, accessory device 14 and adapter 16 may be configured to attach to an inside wall of a food compartment of a consumer appliance, such as a refrigerator or oven, or to an inside surface of a laundry compartment of a washer or dryer.
Host 12 may perform a primary function. As illustrated herein, host 12 is a refrigerator performing a cooling cycle and/or an ice making cycle. Although the figures show an appliance comprising a refrigerator, it shall be understood that the invention is not limited to refrigerators or appliances in general.
Accessory devices 14 and 18 may also perform at least one primary function. The primary functions of accessory devices 14 and 18 can be different from the primary function performed by host 12, although they need not be.
Host 12 can be configured to provide or receive at least one substance to or from accessory devices 14 and 18. Similarly, accessory devices 14 and 18 may also be configured to provide or receive at least one substance to or from host 12. It is not necessary that the substance transferred between host 12 and accessory devices 14 and 18 be used in performing the primary function of host 12 or accessory devices 14 and 18, or otherwise be related to the primary function of either accessory device.
As mentioned previously, in instances where the accessory device includes an incompatible substance communication coupling system that prevents direct coupling of the consumer accessory to host 12, adapter 16 may be provided for indirectly coupling the accessory device to host 12. Adapter 16 operates to establish a substance pathway for transferring the desired substance between host 12 and accessory device 18 having the incompatible substance communication coupling system.
At least one substance can be supplied to accessory devices 14 and 18 from host 12, or from accessory devices 14 and 18 to host 12. The supply of the substance can be uni-directional in that either host 12 supplies the substance to accessory devices 14 and 18 or accessory devices 14 and 18 supply the substance to host 12. The supply of the substance can also be bi-directional in that the supplied substance can be delivered from host 12 to accessory devices 14 and 18 and from accessory devices 14 and 18 to host 12.
Substance communication between host 12 and accessory devices 14 and 18 may include liquid communication, gaseous communication, and/or solid communication, among others. Liquid communication may include the transfer of a liquid, such as water, hydraulic fluid, or cooling fluid, among others, between host 12 and accessory devices 14 and 18. Gaseous communication is similar to liquid communication, except the medium by which the substance is transferred is a gas rather than a liquid. For example, host 12 may provide a supply of pressurized air to accessory devices 14 and 18. Solid communication may include the transfer a solid material, such as a powder, tablets, or pellets, to name a few. It shall be appreciated that these are only a few examples of the various types of substances that can be transferred between host 12 and accessory devices 14 and 18.
As illustrated, accessory device 18 is a medicine module. The module may provide convenient access and consumer visibility to a supply of medicine for a consumer and allow control of temperature and humidity independently of the host 12 by the use of a secondary coolant communicated from the host 12, or alternatively by treated air supplied by the host 12.
It will further be appreciated that, while the embodiments in the drawings illustrate specific types of substance communicating devices, such as a host 12 that may operate and a substance provider, an accessory device 14 that may operate as a substance consumer, and an adapter 16 that may act as a conduit for the transfer of substance from host 12 to accessory device 18, variations from this configuration are possible. These variations include systems with only two electromagnetic service communicating devices, systems with more than three substance communicating devices, systems where any of the devices may be substance consumers and/or substance providers, systems where multiple services are communicated and systems where services are received by one device, converted in some manner, and then passed to a third device. Furthermore, in the following description, certain components of connector systems and proximity systems are described for the illustrative purposes as being associated with specific substance communicating devices. For example, a proximity switch, target or sensor may be described as being located in a substance provider, substance consumer, host or portable device. It will be appreciated that these system components may be alternatively assigned to the various substance communicating devices depending on the application.
Host 12 and accessory device 14, may each comprise at least one substance communication coupling system component, respectively referred to herein as a host substance communication coupling component 20 and an accessory substance communication coupling component 22.
Host substance communication coupling component 20 and accessory substance communication coupling component 22 have complementary configurations that enable the substance communication coupling components to be coupled to one another, thereby establishing a substance pathway over which desired substances can be transferred between host 12 and accessory device 14.
Host 12 also has a second host substance communication coupling component 20 provided on its front surface for the adapter 16. In instances where accessory device 18 includes an incompatible substance communication coupling component, and the adapter 16 is used as an intermediate component to connect accessory device 18 to host 12, then adapter 16 will have a second device substance communication coupling component 23 for engagement with a device substance communication coupling component 21 of accessory device 18 as well as host substance communication coupling component 22 for connection with the host substance communication coupling component 20 of the host 12. Therefore, accessory substance communication coupling component 22 may have the same general configuration whether included as part of accessory device 14 or adapter 16, and host substance communication coupling component 20 may have the same general configuration whether it couples directly with an accessory device or an adapter. Accordingly, for purposes of discussion, the various features and operation of substance communication coupling component 22 will hereinafter be described in connection with accessory device 14, but it shall be appreciated that exemplary accessory substance communication coupling component 22 may also be used in conjunction with adapter 16.
Referring to Figures and 5, host substance communication coupling component 20 can be integrally formed with host 12 or may be an add-on device. For purposes of discussion, host substance communication coupling component 20 is shown integrally formed with host 12. When configured as an add-on device, host substance communication coupling component 20 may also function as an adapter to enable a host and an accessory device having dissimilar substance communication coupling components to be indirectly coupled to one another. Host substance communication coupling component 20 may be removable or non-removable from host 12. Host substance communication coupling component 20 can be configured to transfer or receive a single substance or multiple substances.
Similarly, accessory substance communication coupling component 22 may be integrally formed with accessory device 14 or may be an add-on component. For purposes of discussion, accessory substance communication coupling component 22 is shown integrally formed with accessory device 14. When configured as an add-on component, accessory substance communication coupling component 22 may also function as an adapter to enable a host and an accessory device having dissimilar substance communication coupling components to be indirectly coupled to one another. Accessory substance communication coupling component 22 may be removable or non-removable from accessory device 14. Accessory substance communication coupling component 22 can be configured to transfer or receive a single substance or multiple substances.
The host substance communication coupling component 20 may be provided with a receptacle 23, including a recess 24, proportioned to accept a plug 26 extending from the accessory substance communication coupling component 22. Plug 26 may be provided with ridges 28 to facilitate alignment of the substance communication coupling components. It will be appreciated that host substance communication coupling component 20 and accessory substance communication coupling component 22 may include various features to facilitate coupling of accessory device 14 to host 12. For example, ridges 28 are merely one example of the type of features that may be incorporated into host substance communication coupling component 20 and accessory substance communication coupling component 22 to aide alignment and coupling of accessory device 14 to host 12. In practice, other configurations may also be employed to accommodate various design considerations of a particular application.
Referring to
Substance provider 30 may be connected by way of an internal substance line 34 to substance flow regulating device or substance switch 36 that extends through a housing 13 of the host 12. It should be understood that various substance switches may be used to control substance flow through substance line 34, such as a valve, a pump, or a fan. The type of substance switch may be designed to fail in a non-flowing condition, such as a normally closed valve requiring power to open.
It should be noted that housing 13 may be an integral part of host 12 or may be a separate component. For purposes of discussion, housing 13 is illustrated as an integral part of host 12.
For purposes of discussion, substance line 34 is illustrated generically as a tube-like structure. The generically illustrated configuration is not intended to depict any particular configuration, but rather schematically represents a variety of potentially different configurations. In practice, the actual configuration may vary depending on, at least in part, the type of substance being transferred, packaging requirements, and manufacturing considerations, to name a few. For example, a substance line for transporting a high pressure fluid or gas may have a different configuration than a substance line for transporting a powder, due at least in part to the higher operating pressure loads that may be imposed on the fluid substance line as opposed to the powder substance line. Thus, it shall be appreciated that substance line 34 may include other configurations to accommodate various design considerations, including but not limited to, the type of substance being provided.
Referring to
Substance switch 36 may further include a piston 44 slidably disposed within substance pathway 38. Piston 44 is moveable between a closed position, as shown in
The range of travel of piston 44 within substance pathway 38 can be controlled by trapping the piston between a first shoulder 48 and a second shoulder 50, which act as stops to prevent piston 44 from traveling beyond the shoulders 48 and 50. The distance between the shoulders 48 and 50 defines the range of travel of piston 44. Substance pathway 38 has a smaller diameter in the region of shoulders 48 and 50 than an outer diameter of piston 44, thereby preventing the piston 44 from traveling beyond either shoulder 48 or 50.
An end 52 of piston 44 may include a conical surface 54 that engages a correspondingly shaped mating surface 55 (See
An end 56 of piston 44 opposite end 52 can engage or be movable toward second shoulder 50 when the piston is arranged in the open position, as shown in
As can be observed from
Piston 44 may be biased toward the closed position as shown in
Referring to
Similar to substance line 34, accessory substance line 64 is also illustrated generically as a tube-like structure, and is not intended to depict any particular configuration. In practice, accessory substance line 64 may have a variety of potentially different configurations depending on the type of substance being transferred, as well as other design considerations.
Referring to
At least one of the piston 44 and the magnetic member 63 is a magnet while the other may be either formed of a magnetically responsive material or may be a magnet. When substance communication coupling components 20 and 22 are engaged, magnetic member 63 acts as a proximity target for piston 44, which acts as a proximity sensor in a manner described below.
More particularly, in the illustrated structure of
Accessory device 14 can be decoupled from host 12 by reversing the previously described process for coupling the two devices. Separation of accessory substance communication coupling component 22 from host substance communication coupling component 20 displaces magnetic member 63 away from piston 44, thereby allowing the magnetized material in end 58 of valve body 37 to return piston 44 to the closed position and into engagement with first shoulder 48 of valve body 37.
Referring to
The accessory device 14′ may be provided with a substance consumer 32′ connected by a substance line 64′ through a passageway 80 in the housing 15′ to a second interface 82 engageable with the first interface 74. The accessory device 14′ may further be provided with a biasing member, such as a spring 84, for biasing the second interface 82 partially through passageway 80. The accessory device 14′ is further provided with a proximity target 62′ chosen for cooperation with the proximity sensor 76.
Coupling of accessory device 14′ to host 12′ can be accomplished by positioning accessory device 14′ adjacent host 12′ in such a manner that accessory substance communication coupling component 22′ is generally aligned with host substance communication coupling component 20′, as shown in
It should be noted that the proximity sensor 76 and substance switch 36′ are either unpowered or may rely on a secondary power supply for power. Substance switch 36′ may also be activated or powered by the presence or absence of a static magnetic field. For example, line 78 attached to proximity sensor 76 may operate as a plunger for activating the substance switch 36′. In this arrangement, at least one of the proximity target 62′ and proximity sensor 76 may be formed of a magnetic material. Positioning proximity target 62′ in the vicinity of proximity sensor 76, such as may occur when attaching accessory device 14′ to host 12′, the proximity sensor 76 will be displace toward proximity target 62′ due to the magnetic attraction of the two components. This in turn will withdraw plunger line 78 and activate substance switch 36′. Plunger line 78 may be biased toward substance switch 36′, which will enable the substance switch 36′ to be deactivated when accessory device 14′ is detached from host 12′.
Referring to
A proximity sensor 76″ is associated with a sender 90. The sender 90 is powered by a service provider 30b″, such as an electrical power supply, and is connected to the substance switch by a line 92 to selectively activate substance switch 36″ in response to the detection of an appropriate proximity target. The communication along line 92 may, for example, be by means of an electrical signal, an acoustic or electromagnetic wave, pneumatic or hydraulic pressure, or a physical displacement of a linking member. The proximity sensor 76″ may also be powered by service provider 30b″ either directly or indirectly through the sender 90.
The accessory device 14″ may be provided with a substance consumer 32″ connected to a substance line 64″ extending through an aperture 80″ in the housing 15″ and terminating in a second interface 82″ engageable with the first interface 74″. The accessory device 14″ is further provided with a proximity target 62″ chosen for cooperation with the proximity sensor 76″.
Coupling of accessory device 14″ to host 12″ can be accomplished by positioning accessory device 14″ adjacent host 12″ in such a manner that accessory substance communication coupling component 22″ is generally aligned with host substance communication coupling component 20″, as shown in

Alternatively, as shown in
As shown in
It will be appreciated that coupling components for sealing accessory substance communication coupling component 22 to host substance communication coupling component 20 will vary depending upon the type of substance being transferred and the pressures involved. Some systems, such as water systems may use compression fittings that may be completely reusable or partially reusable with the replacement of some components.

In other installations, there may be simple threaded fittings, an example of which will be described subsequently. Still other systems, such as sealed systems for refrigeration, may use welds, brazes, and chemical bonding which are all meant to be permanent. It will be appreciated that for multiple make-break connections turning motion on gasket surfaces is avoided and compression is preferred.

Device interface 106 comprising a cap 107 having a threaded inner surface 109 engageable with the threaded boss 104 of host interface 102. The coupling system 100 further includes a fluidic coupler 111 which may be coupled to substance line 64 leading to a substance consumer (not shown).
The fluidic coupler 111 may be an elongated pipe segment having a fluid passage 113 therethrough and a Swage-Lok™ type seal or a similar flexible seal 115.
Coupling of device interface 106 to host interface 102 can be accomplished by first passing the fluidic coupler 111 into substance line 34 until the flexible seal 115 abuts chamfered exposed end 108 of substance line 34. Next, cap 107 is rotatably driven by the user into engagement with the threaded boss 104 driving the flexible seal 115 into sealing engagement with chamfered exposed end 108 of substance line 34.
It shall be appreciated that any of the coupling systems illustrated in

A coupling system 130 includes plug 116 and receptacle 126 which are selectively interengageable. A proximity target 132 and a proximity sensor 134 are respectively associated with first subsystem 110 and second subsystem 120 to selectively activate the substance switch 125 when the plug 116 and receptacle 126 are engaged to permit the flow of the substance from the substance provider 124 to the receptacle 126, so that it may subsequently be provided along a substance line 138 between receptacle 126 and plug 116, and then along substance line 118 to substance consumer 114.
It will be appreciated that while host 122 is illustrated as including a substance provider, and accessory device 112 is illustrated as including a substance consumer, accessory device 112 may alternatively or additionally include a substance provider and host 122 may alternatively or additionally include a substance consumer. It will further be appreciated that while plug 116 is illustrated as being associated with substance consumer 114 and receptacle 126 is illustrated as being associated with substance provider 124, it is contemplated that plug 116 and receptacle 126 may be male or female coupling system components so long as the components are capable of interengaging to permit the transfer of substance there between.
