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 substance communicating devices and coupling systems for connecting substance communicating devices. 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 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, a consumable might be a detergent and/or a softener. For a clothes dryer, a 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 may 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 are 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 “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, or a substance holder, such as a bottle, or 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.
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 terms “substance communication coupling system” or “substance service connector system” refer to any connector system having at least two separate substance communication coupling system components, each of which is associated with a useful device. The substance communication coupling system 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 “substance switch” is any component used to selectively facilitate the communication of a substance between components of a substance coupling system, such as by drawing the components into engagement or by permitting the flow of a substance from one of the components for transfer to the other of the components.
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.
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 fluidically-aligned supply and receiver ports with a gap therebetween.
As used herein, an “electromagnetic service” is electrical power or data. An electromagnetic service may comprise multiple categories of electromagnetic service, such as electrical power and data in a single signal. An electromagnetic service may be provided continuously or for specified times or for specified amounts or for the duration of certain events, such as the duration of coupling to provide timed dispensing. Alternatively, an electromagnetic service may be provided in quanta, such, as packets of data. Also alternatively, an electromagnetic service may include data encoded into in waves such as light, radio, and sound.
“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.
“Electrical power communication” is the coupling of at least two devices to supply electrical power from at least one of the devices to the other of the devices, such as through directly connected electronic lines or through wireless power communication (also referred to as wireless power transmission). Wireless power communication may include any type of wireless power communication, including, without limitation for illustration purposes, microwave transmission, laser transmission, and magnetic fields. Exemplary categories of power communication include the type of power, e.g. alternating current (also known as AC) or direct current (also known as DC), supplied to the functional device and variations in the characteristics of the power, such as the voltage or current.
“Data communication” is the coupling of at least two devices to transmit data from at least one of the devices to the other of the devices, such as through directly connected electronic lines or through wireless data communication (also referred to as wireless data transmission). The data may be transmitted as a separate signal or embedded in electrical power communication. Wireless data communication may include any type of wireless data communication, including, without limitation for illustration purposes, wireless network technology (a/k/a Wi-Fi), radio transmission, light transmission, and acoustical transmission. Exemplary categories of data communication include encrypted and unencrypted data. Data communication also includes communication for different protocols, including physical layer protocols and software layer protocols. Examples of physical layer protocols are a wired Ethernet and a wireless (using Wi-Fi) network, both of which may support the same data packet structure. Examples of software layer protocol are Zigbee® and Bluetooth®. Data communication may also be completed by way of an analog mechanical transmission means such as by means of fluidic pulses created by positive pressure systems or vacuum systems or by a mechanical logic transfer means, such as the throwing of switches or levers to actuate or transmit information about a control state.
“Communicating” as used herein with respect to an electromagnetic service means supplying or receiving an electromagnetic service. As used herein, communication of electromagnetic service includes both uni-directional and multi-directional communication between any two devices, either directly or through an adapter, as defined herein.
A “substance communicating device” is any substance holder, substance provider or substance consumer that is capable of communicating substance with another device. Examples of a substance communicating device include a dispenser, a filter, a water filter, an air filter, a detergent dispenser, a drink dispenser, a detergent cartridge, a bottle, a jug, a flavoring dispenser, a steam dispenser, a fragrance dispenser, a food ingredient dispenser, a cycle accessory, and a chemistry dispenser.
A “substance communicating system” is any combination of substance communicating devices capable of communicating a substance therebetween.
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.
A “switched service connector system” is a service connector system having a switching capability in at least one of the service connector components operable to selectively permit the communication of a service between the components of the service connector system.
A “service switch” is any component used to selectively permit the communication of a service between components of a service connector system. A service switch which selectively permits the communication of a substance may be referred to as a “substance switch”. A service switch may be associated with more than one type of service. For example, an electromagnetic service switch may be associated with, integrated with, or comprise a substance switch or may be independent of a substance switch.
A “switch component” is any component in an assembly of components that cooperate to selectively operate a service switch, including, but not limited to, linkages, actuators, mechanical switches, and any sub-component thereof.
A “service line” is a pathway for transferring a service from one location to another. The service line may have any of a variety of configurations, including but not limited to a pipe, conduit, wire, tube, channel, and fiber optic cable, to name a few. More particularly, to transfer electrical power or data service communication, an electromagnetic service line may include an electrically conductive wire, an optical data cable, or a wireless transmission system.
The terms “provide” and “supply” and any variation thereof, are used herein to denote a source of the substance or an electromagnetic service relative to a device receiving the substance or electromagnetic service. Neither term is limited to the original source of the substance or electromagnetic service. A device that provides or supplies the substance or electromagnetic service may simply be passing on the substance or electromagnetic service 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 a substance or an electromagnetic service relative to the device providing the substance or electromagnetic service. The term is not limited to the ultimate consumer of the substance or electromagnetic service. The term “receive” is applicable as well to a device that may simply be passing on the substance or electromagnetic service from the source, such as an appliance, to a device that will consume, as hereinafter defined, the substance or electromagnetic service. The device which receives a substance or an electromagnetic service is not necessarily the end consumer of the substance or electromagnetic service.
The term “consume” and any variation thereof, as used herein, denotes the act of employing or dispensing at least a portion of the substance or electromagnetic service received in connection with performing a function.
The term “coupled” and any variation thereof, as used herein, includes any type of connection that permits transfer of a substance or an electromagnetic service 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 or an electromagnetic service. The term “coupled” includes both fixed and removable coupling, as well as both continuous and intermittent coupling.
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.
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 may 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.
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 provider 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 the parent devices or may directly or indirectly regulate the flow of a service along a service line. The proximity systems disclosed herein employ contact proximity systems, wherein the proximity target and proximity switch use physical contact to detect the proximity of the two parent devices.
A “plug” as used herein is a generally male electromagnetic service connection component.
A “receptacle” as used herein is a generally female electromagnetic service connection component.
An “adapter” as used herein 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 services between the first and second useful devices. An adapter may receive a service from the first useful device and provide a modified version of the service to the second useful device, for example, by providing an electrical power service using a different voltage or providing a data service using a different data structure or signal type. In some applications, multiple adapters may be interposed between two accessory devices. In other applications, three or more devices may be coupled to a single adapter, such as between a host and two accessories. In some applications, the adapter may itself be an accessory device providing a useful function not provided by the accessory 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.
Referring to
First substance communicating device 12 may communicate, through an interface or service connector system 18, a substance with second substance communicating device 16, and may as well communicate one or more additional services, such as a data service or a power service. Service connector system 18 may include one or more service couplers or connector components, such as 18A and 18B, for enabling the communication of one or more services, such as, for example, multiple substance services or a substance service and an electromagnetic service. For example, first substance communicating device 12 may be an automatic clothes washer acting as a host for the second substance communicating device 16, and second substance communicating device 16 may be an additive dispensing accessory capable of dispensing one or more fabric treatment chemicals, such as detergent, bleach or softener, for use by the automatic clothes washer in the processing of a fabric load. As another example, first substance communicating device 12 may be a refrigeration appliance having a water supply and acting as a host for the second substance communicating device 16, and second substance communicating device 16 may be a flavoring dispensing accessory capable of dispensing one or more food flavoring chemicals, such as fruit flavored drink powder, for use by the refrigeration in providing consumers with a flavored drink. As another example, first substance communicating device 12 may be a refrigeration appliance having a water supply and acting as a host for the second substance communicating device 16, and second substance communicating device 16 may be a drink dispensing accessory holding one or more food flavoring chemicals, such as fruit flavored drink powder, and capable of receiving cooled water from the refrigeration appliance, mixing it with a food flavoring chemical, and dispensing a drink to a consumer. These and other examples are discussed below in more detail.
In general, first substance communicating device 12 may be configured to perform an operation on a physical article 11, such as clothing or food, using a resource such as water, temperature-controlled air (hot or cold), steam, gas, or electricity, provided to first substance communicating device 12 by interfaces, not shown, with a utility, not shown, supplying the resource. Examples of appliances that perform an operation on a physical article include a wide range of device types, including but not limited to, washers, dryers, ovens, ranges, steam cookers, ice makers, refrigerators, drink makers and the like. Articles 11 are the objects upon which a user intends the appliance to perform its cycle of operation. Typical examples as mentioned above would include food and clothing.
Smart process control apparatus 14 is configured to implement and control a cycle comprising at least one operation. Smart process control apparatus 14 may comprise one or more components, not shown, such as electronic control boards, wiring and wiring harnesses, power-supplies, sensors integrated with the electronics as digital or analog inputs, and actuators like valves, relays, heaters, and the like, any or all of which may integrate with the electronics as digital or analog outputs.
Second substance communicating device 16 is configured to hold, carry, supply, communicate with, or otherwise interact directly with a consumable 24. When performing a cycle of operation on an article 11, first substance communicating device 12 will often use at least one consumable 24. A consumable 24 in one sense comprises a substance, device, or other product that would be at least partially consumed or transformed by first substance communicating device 12 during a cycle of operation on an article 11, such that consumable 24 may be periodically replaced or replenished. The period after which consumable 24 may be replaced or replenished may be, but is not limited to, a single cycle of operation, multiple cycles of operation, an amount of time, or a number of uses. For example, many common washing machines require that a user place a single dose of detergent in a dispenser prior to initiating a cycle of operation. For each subsequent cycle of operation, the user must again place a single dose in the dispenser, as a single dose of detergent is consumed by the washing machine during each cycle of operation.
In some cases, the consumable 24 may be the article 11, on which the first substance communicating device 12 performs the cycle of operation, and the consumable may be subsequently consumed by a user. A consumable 24 may, for example, be anything that would be consumed or otherwise used by a person, such as food, beverages, cosmetics, or medicine. For example, in a cooking or refrigeration appliance, the consumable may be a food item communicated from a dispenser to an appliance, and the cycle of operation performed by the appliance may be heating or cooling the food.
Consumables are to be distinguished from resources, although resources may in some circumstances be “consumed” during a cycle of operation. Resources are commodities that are continuously available to an appliance, and used by the appliance in its cycles of operation on articles 11 that are supplied by external utilities, such as a residential water, power, data or natural gas distribution system, or are available from the ambient environment, such as air. In some cases, a material resource, such as air and water, may also be considered an article 11 as in a refrigerator that chills and dispenses water. That is, water in that instance is a resource (continuously available to the refrigerator from a residential utility), but also an article 11 (intended by the user for the refrigerator to act upon). The cycles of operation performed by the refrigerator would include the chilling and dispensing. Things that hold or supply resources, such as water supply lines or air conduits are not considered consumable holders 16. They would be “resource holders”, which may be supplied by resource providers. In a refrigerator, for example, water supplied to the first substance communicating device 12 would be considered a resource and/or an article 11. If flavoring is mixed with the water supplied to first substance communicating device 12, the flavoring may be considered a consumable 24, and whatever holds/supplies the flavoring is then considered to be second substance communicating device 16.
Consumables are also to be distinguished from parts in an appliance, although parts wear out and need to be replaced or replenished as do consumables. Parts are devices, without which a cycle of operation by the appliance or a principal function of the appliance would be hampered. Examples include valves, actuators, switches, tubes, lamps, wiring, motors, pumps, seals, gears and the like. Consumables, on the other hand, are typically not critical to the operation of the appliance, although they provide a benefit to a user of the appliance. An appliance may typically still operate on an article 11 in some fashion without a consumable, though not necessarily as effectively or efficiently.
Second substance communicating device 16 comprises a device that holds or contains consumable 24. Typically, consumable 24 is contained by a consumable holder. In some cases, second substance communicating device 16 may be nested within one or more other consumable holders. For example, a cartridge holding a consumable may be disposed in a dispenser.
In some cases articles 11 on which the appliance operates may not be contained by a consumable holder, and may not be consumables in the sense herein defined. Rather, the articles 11 may be enabled to perform at least some of the functionalities of a consumable and/or a substance communicating device. An example of an article 11 with substance communicating device capabilities is a shirt having a bar code thereon containing information that is directly readable by first substance communicating device 12. The bar code may be, for example, on a performance tag. First substance communicating device 12 may use data and/or information represented by the bar code for use in configuring and selecting the cycle of operation of the appliance. The bar code may be read by first substance communicating device 12 while the shirt is being operated contemporaneously with the cycle of operation.
A performance tag is an information holder either integrally formed or selectively attached to an article 11 and adapted to maintain its integrity over the life of the article 11. For example, a performance tag for clothing would be adapted to maintain its integrity throughout the repeated processes of washing in a washing machine appliance, drying in a dryer, being cleaned at a dry cleaners, being ironed, being left in the sun, and being subjected to the impacts sustained during usage. Examples of impacts sustained during usage for a shirt are those that might occur during a soccer match where the shirt impacts the earth and other players at considerable speeds and forces repeatedly. Likewise, performance tags for dishes would be subjected to similar impacts, and similar wash and dry cycles from a dishwasher. Performance tags integrally formed with fabric items might be sewn in, glued in, woven in, stamped on, or printed on during the manufacturing of the article 11 or by a home machine adapted to integrate the article 11 and the tag. Performance tags integrally formed with dishware might be glued, stamped, printed, embossed, cast, molded, or otherwise formed during the manufacturing of the article 11 or by a home machine adapted to integrate the article 11 and the tag. Performance tags that are selectively attached to an article 11 could be attached by sewing, gluing, pining, sticking, printing, embossing, or other like methods in the home environment for articles 11 not specifically adapted for receiving a performance tag. Performance tags are constructed of any suitable material, which that may be used to hold encoded information about a cycle structure, or information about a consumable, the description of which is contained herein. Examples of materials for holding the information include magnetic strips, bar codes, and images of encoded data including color patterns, shape patterns, plain texts, numeric identifiers, and the like. An appliance having a cycle architecture and being in communication with a performance tag (as for example by using a consumable reader) may optimize the cycle of operation in the appliance for the article 11 in response to the cycle structure, data about a cycle structure, and/or data about a consumable held by the performance tag. Performance tags may either hold information or hold other information about how to find the information. An example of a performance tag that holds other information is a performance tag holding a URL wherein the data returned when invoking the URL is the information. Further, the appliance may alter or optimize the user experience by providing information on a user interface in response to the cycle structure, data about a cycle structure, and/or data about a consumable.
Other examples further illustrate the foregoing distinctions. Consider using an oven to cook a turkey in a roasting pan where there is a steam dispenser with a basting cartridge for automatic basting. The turkey is the article 11 upon which the appliance (the oven) performs its cycle of operation (cooking). However, the turkey is also a consumable in the sense that it is a food item to be consumed by the user. The basting cartridge would be a consumable holder and its contents a consumable. The water used to generate the steam is a resource, making the steam a changed resource. The roasting pan would be a second consumable holder, holding the turkey. The appliance or the roasting pan, or some other device (such as a performance tag described below) may also hold information about the turkey or how to cook a turkey or how to cook a turkey in different kinds of ovens. Such information would be considered information about a consumable and information about a cycle structure.
Consider also a powdered detergent box with a performance tag configured to communicate with an appliance contemporaneously with the dispensing of the detergent to a washer. The washer is the appliance, the detergent is a consumable, and the box is a consumable holder. The performance tag may hold information about the chemistry of the powder, information about cycle structures, and data about cycle structures wherein the information and data are associated with other information comprising appliance types, fabric types, stain types, and the like so that the data and information may be used alone or combined with the other information to create a cycle of operation in response to the data and the information and in response to the user and the user preferences about the cycle of operation, the data, the information, and the other information.
Consider also a detergent pellet with an etched or embossed, or imprinted cycle structure enabled to communicate with an appliance contemporaneously with being introduced into a washing machine before or during a wash cycle. Here, the washing machine is an appliance and the detergent pellet is a consumable. There is no separate consumable holder. The cycle structure is intended to effect the cycle of operation (washing). Consider also a detergent pellet having a data pod. The detergent pellet is a consumable, but the data pod is a form of performance tag that could communicate with an appliance contemporaneously with being introduced into the use environment for the purpose of effecting the cycle of operation.
A consumable or a consumable holder or a performance tag or data pod, or anything that may hold and convey information (consumable information holder) might comprise one or more cycle structures. A first cycle structure may be associated with a first appliance or first appliance type and a second cycle structure may be associated with a second appliance or a second appliance type such that the appropriate cycle structures are introduced to the appropriate appliance or appliance type when the consumable or consumable holder is in useful communication with the appliances. For example, a frozen food (a consumable) or a package of frozen food (a consumable holder) might have cycle instructions for freezing, defrosting, or preserving cycles in a refrigerator or freezer appliance, and also might have cycle instructions for defrosting, cooking, or warming cycles for a cooking appliance like an oven or microwave.
A consumable information holder may comprise one or more user interface data sets, with or without cycle structures, which may be communicated to a user interface, such as might be on the appliance. User interface data is considered to include anything that may be rendered to be responsive to a user's senses, such a visual displays, audible sounds, and tactile displays. A first user interface data set may be associated with a first appliance or first appliance type and a second user interface data set may be associated with a second appliance or a second appliance type such that the appropriate user interface data are conveyed to a user interface associated with the appropriate appliance or appliance type when the consumable or consumable holder is in useful communication with the appliances. For example, a frozen food (a consumable) or a package of frozen food (a consumable holder) might convey to a refrigerator an expiration date to be rendered on a user interface on the refrigerator. The frozen food or its package might also convey to an oven serving suggestions to be rendered on a user interface on the oven.
Consumables, consumable holders, performance tags, data pods and the like (consumable information holders) may be enabled not only to provide data, but also may be configured to receive and store information associated with the consumable. Exemplary information includes data about a consumable, a cycle structure, data about a cycle structure, tracking the number of times a shirt or a dish is washed, the number of cycles and the parameters thereof, which have been executed by or in combination with an appliance and consumable holder. It may also include the types of consumables introduced into the use environment, information entered into an appliance user interface including cycle selections, usage patterns, user information, user identification, other data associated with the cycle of operation of an appliance, and any data held by a data source in communication with the holder, tag, or pod which either the data source writes to the holder, tag, or pod, or any data or the holder, tag, and pod reads from the data source. Such information may be sequentially added to a database on the consumable information holder for later retrieval. For example, a shirt with a performance tag may keep data about how many times it has been washed, about different wash cycles it has been through, and the specific machines in which it has been washed.
More specific examples of consumables 24 for use with or by appliances such as first substance communicating device 12 include dispensing additives for laundry washers, dryers, or combination washer/dryer appliances. Other additive examples are provided in the definition of consumables above.
An additive dispenser in this case would be second substance communicating device 16 and may be a single load dispenser that dispenses all of additive contained therein during a single cycle or a bulk dispenser that dispenses only some of the additive contained therein during a single cycle. An appliance comprising a bulk dispenser may meter and dispense the correct amount of additive for each particular load and provide information to the user regarding the remaining amount of additive in the bulk dispenser after dispensing.
Because each additive may have different parameters associated with its use, information about each consumable may be provided with each consumable 24. This information may be provided on the packaging of consumable 24 (i.e. the consumable holder), in consumable 24, or by any other suitable means (performance tag, data pod, user interface, etc.). For example, different additives may have different concentrations, and the amount of a given additive needed for a particular load will vary depending on the concentration of that additive. The amount of a particular additive needed to complete a cycle of operation will also depend on the amount and type of laundry being treated, as well as the condition of the laundry (e.g. soil and stain level). The amount, type, and condition of the laundry may be determined utilizing information supplied by the user, information gathered by sensors associated with the appliance, or information otherwise obtained during the operation of the first substance communicating device 12.
Additional information provided with the consumable may also be used to tailor the cycle of operation to that consumable 24. In a laundry application, the additive will have to be dispensed at the right time during the cycle, such as before, during, or after wash, rinse, spin, or drying. Particular additives may also require that they are dispensed under certain conditions, such as at a given water temperature or air temperature. Additionally, particular additives might require at least one additional step in a cycle for optimal performance. For example, the presence of a particular additive might require that the cycle structure be augmented by inserting an additional ordered collection of steps such as filling at a new temperatures to a new level after spinning, then soaking for an amount of time, then draining, then spinning for a new amount of time at a new spin speed between the original step in the cycle and the last step in the cycle.
The smart process control apparatus 14 or electronics 30 may determine parameters to be used for the cycle of operation or the structure of the appropriate cycle of operation or changes to an existing cycle of operation for different operations based on the information provided with consumable 24, user input, and information obtained by sensors associated with first substance communicating device 12. Exemplary types and sources of information are found in the following table:
Another example of a consumable includes filters used by first substance communicating device 12. Refrigerators, dryers, washers, and dishwashers are all known to use filters that are consumed in the sense that they must be replaced after a certain amount of time or usage due to wear and dirtying of the filter. Filters, in particular, depending on the embodiment may be construed as a consumable, a consumable holder, or both. For example, if there is a filter assembly holding a filtering material, then the filter assembly may be considered a consumable holder and the filtering material may be considered a consumable because it is disposed of after its usability is consumed; its life and the life of the consumable holder are significantly different. On the other hand, the filter assembly and the filter material may be integrally formed and introduced and removed from the use environment as a unit. In this case, the assembly and the filter material would be considered both a consumable holder and consumable because the assembly and the filter material comprise functionality and attributes of both consumable holders and consumables.
Consumables may also include food, as mentioned above, and articles of clothing. Such consumables may or may not be contained by a consumable holder. However, non-contained consumables may still have consumable holder functionality in that they may comprise information about the consumable that is retrievable by the appliance. For example, a food item may carry information about itself that is contained in edible ink printed on the surface of the food item.
Returning to the drawings, service connector system 18 may be an internal or external interface configured to couple second substance communicating device 16 and first substance communicating device 12. Substance communication system 10 may also be provided with an interface or service connector system 20 for removably connecting one or more additional accessory devices, described below. Interface 20 couples accessory devices 22, 23, or 25 to second substance communicating device 16, but it will be appreciated that such an interface may alternatively or additionally be provided on first substance communicating device 12.
Interface 20 may include one or more service couplers or connector components, such as 20A, 20B, and 20C for enabling the communication of a one or more services such as substance service, power service, or data service provided by any other source or device, such as devices 22, 23 and 25, that may be advantageously used with the first substance communicating device 12 and/or second substance communicating device 16. One or more of the accessory devices 22, 23 and 25 may have a process control apparatus, not shown, that may interact with or become a part of system architecture and electronics 15 when coupled with substance communication system 10.
Accessory device 22 may, for example, comprise a power source, a consumable source, a consumable dispenser, a consumable reader, a data processor, or a component that may facilitate engagement or interaction with second substance communicating device 16. In another example, second substance communicating device 16 may act as an adapter between first substance communicating device 12 and accessory device 22 for communicating a service therebetween. Accessory device 23 may be a consumable reader, including a bar code or RFID tag reader and a microprocessor. Alternatively, a consumable reader may be incorporated into first substance communicating device 12 or second substance communicating device 16 and accessory device 23 may be a sensor for the consumable reader. Accessory device 25 may be a bulk source of consumable 24, such as a large bottle of detergent, which provides second substance communicating device 16 with a replenished supply of consumable 24 as second substance communicating device 16 dispenses a dose of substance 24 into first substance communicating device 12.
System architecture and electronics 15 may include software, not shown, enabling at least one of first substance communicating device 12, second substance communicating device 16, or accessory devices 22, 23 or 25 to discover other devices using network messages.

In one embodiment, a changed substance is communicated through service connector component 18F. The substance may initial be a resource or a consumable and will have been changed by one of the substance communicating devices prior to being communicated to the other substance communicating device. A changed substance may be one whose properties have been changed by a chemical, thermal, electrical, or other type of process. For example, a changed substance may be one that has been heated, cleaned, cooled, mixed with a consumable, or generally treated in such a way that it has at least one property with a different value.
As mentioned above, service connector component 18E may include a power service connector. A power service connector component may deliver power to a second substance communicating device 16 or it may deliver power to smart process control apparatus 14. The power may be conventional AC at 110 V, DC at 12 V, or another type or amount, such as the power that is transmitted by a USB connection. In some cases, a service connector component may function as both a data and a power source.
Second substance communicating device 16 has an internal source 26′ and/or an external source 26″ of a consumable 24. If second substance communicating device 16 has the optional process control apparatus 28, as shown in
Second substance communicating device 16 may have components of system software architecture and electronics 15 shown in
Alternatively, electronics 30 may communicate with portions of system software architecture and electronics 15 in the first substance communicating device for the purposes of observing the cycle of operation and modifying the cycle of operation. Electronics 30 may observe the cycle of operation using an appropriate data collection scheme, such as those disclosed in PCT Application Serial Number US2006/022430, filed 8 Jun. 2006, entitled “Software Architecture System and Method of Communication with, and Management of, at least One Component within a Household Appliance,” supported by software of the system software architecture and electronics 15. These data collection schemes include, but are not limited to: requesting data from system software architecture and electronics 15, such as data stored in a data storage device 34 or data processed by the software architecture received from the first substance communicating device 12 such as unsolicited events from the cycle of operation; and creating new events that may be received by communicating with a software architecture having a data acquisition (DAQ), not shown, as disclosed and defined in the above referenced PCT patent application and specifying the events to the DAQ for creation by the DAQ.
In addition, electronics 30 may alter a cycle of operation of one of the devices 12, 16 in response to the observations, such as in the manner described in the above referenced PCT patent application. In a first embodiment, electronics 30 may alter the cycle of operation by requesting software in the system software architecture and electronics 15, so that the smart process control apparatus 14 will enter an alternate operating mode enabling electronics 30 to directly control, partially or wholly, the cycle of operation. In a second embodiment, electronics 30 may alter the cycle of operation by making specific requests to system software architecture and electronics 15. In a third embodiment, the electronics may selectively alter the cycle structure using any of the techniques described herein. Electronics 30 may include a controller 32 and software architecture, not shown, similar to system software architecture and electronics 15 of first substance communicating device 12 and/or a software architecture driver (not shown). Electronics 30 may be powered by second substance communicating device 16 or via connection to the first substance communicating device 12. Electronics 30 may further comprise a client 40. Client 40 may comprise a plurality of arbitrary software components, system software architecture and electronics 15, not shown, an instance of system software architecture and electronics 15, a converter, and any other software and data storage and data access functionality.
It will be appreciated that some or all of the above described components of the electronics 30 may alternatively reside in the first substance communicating device 12 in any accessory or other device in data communication with the second substance communicating device.
The second substance communicating device 16 may also have a consumable reader 36, coupled to second substance communicating device 16 by connector component 20C. In this case, consumable reader 36 is communicatively coupled to the controller 32 and to system software architecture and electronics 15. This enables information about consumable 24 and/or about second substance communicating device 16 to be read from a source of information and transferred into the memory of controller 32 or into the memory of at least one control board within the smart process control apparatus 14 wherein the transferring may be accomplished using system software architecture and electronics 15.
Second substance communicating device 16 may have at least one sensor 38 to sense one or more attributes of a consumable 24 and/or its source 26′ or 26″. Attributes may include, but are not limited to, amount, brand, type, composition, structural form, expiration date, dispensing properties, nutritional information, temperature, pressure, and concentration. To store and inventory such data, second substance communicating device 16 may utilize controller 32. Such information or data may also be conveyed to and/or presented at a user interface in second substance communicating device 16 or first substance communicating device 12.
Process control apparatus 28 of second substance communicating device 16 may be configured to detect functionalities of first substance communicating device 12, modify functionalities of first substance communicating device 12, be controlled by first substance communicating device 12, be controlled by electronics 30, or otherwise exchange data with the smart process control apparatus 14 of first substance communicating device 12 either directly through one or more coupling points of service connector system 18 or indirectly through electronics 30 coupled to the first substance communicating device 12 through connector component 18C. Process control apparatus 28 may be used for the transmission, dispensing, supplying, or usage of at least one consumable 24 by responding to control signals resulting in the actuating of a mechanical part, such as a valve, conduit, solenoid, sensor, actuator, spring, transmission, motor, or gear, not shown. Additionally, smart process control apparatus 28 may be configured to modify properties of one or more consumables or resources such as temperature or a chemical property. For example, temperature could be raised by actuating a heater, and chemical properties might be changed by controlling a mixture of at least two consumables and/or resources by using a motor and an auger. Additional auxiliary functionalities not directly related to consumables 24 may be enabled by process control apparatus 28. Process control apparatus 28 may optionally include a mechanism to affect the use of a resource, such as an actuator for a valve.
Second substance communicating device 16 may receive resources from first substance communicating device 12, act on the resources, and return the modified resources to the appliance. For example, in a washing machine or dishwasher, second substance communicating device 16 may receive water from first substance communicating device 12 and return that water to first substance communicating device 12 as grey water or as water mixed with detergent. In this instance, detergent would be consumable 24. Second substance communicating device 16 may thus export modified consumables 24 which have either been operated on by second substance communicating device 16 or that have been operated on by the introduction of at least one resource. Second substance communicating device 16 may also dispense consumable 24 directly to first substance communicating device 12.
Client 40 in electronics 30 may contain a data set linking the model of first substance communicating device 12 or some other functional identifier such as a class identification, or an application programming interface (API) identification type, and/or version to the consumables 24 that second substance communicating device 16 may contain. The data set may further link any of these attributes to a plurality of cycles of operation for first substance communicating device 12. The data set may also link cycle modification or cycle operation data or cycle structure data or data for response to a query message to various combinations of appliances (used as first substance communicating device 12), consumables 24, and selected cycles. The data set may alternatively be in first substance communicating device 12. The data in the data set may be modified by a message sent by one of the constituents of the substance handling system 10, such as second substance communicating device 16, consumable 24, consumable reader 36, or accessory devices 22, 23, and 25.

A service connector system 80 includes plug 66 and receptacle 76, which are selectively interengageable. A switch component 82 is associated with host 62 and a switch component 84 is associated with accessory device 72. For example, switch components 82 and 84 may include switches, actuators, connectors, links, and plates, etc. Switch components 82 and 84 are selective engageable to selectively activate switching valve 75 when plug 66 and receptacle 76 are engaged, to permit the transfer of the service, as shown at 88, from substance provider 74 to receptacle 76, which may then be subsequently transferred along service line 68 to service consumer 64.
It will be appreciated that while accessory device 72 is illustrated as including a service provider 74 and host 62 is illustrated as including a service consumer 64, host 62 may alternatively or additionally include a service provider and accessory device 72 may alternatively or additionally include a service consumer. It will further be appreciated that while only a single service consumer 64 and a single service provider 74 are shown, it is understood that more than one service consumer and service provider may be included, such as one set for communicating a substance and one set for communicating an electromagnetic service. It will further be appreciated that while plug 66 is illustrated as being associated with substance consumer 64 and receptacle 76 is illustrated as being associated with service provider 74, it is contemplated that plug 66 and receptacle 76 may be male or female connector components so long as the components are capable of interengaging to permit the transfer of substance therebetween.

First substance connector component 110 can be integrally formed with first substance communicating device 102 or may be an add-on device. When configured as an add-on component, first substance connector component 110 may also function as an adapter to enable a host and an accessory device having dissimilar substance communication coupling systems to be indirectly coupled to one another. First substance connector component 110 may be removable or non-removable. For purposes of discussion, first substance connector component 110 is shown integrally formed with first substance communicating device 102.
First substance connector component 110 may be enclosed within a housing 114. Housing 114 may be an integral part of first substance communicating device 102 or may be a separate component. For purposes of discussion, housing 114 is illustrated as an integral part of first substance communicating device 102, and more particularly as part of the door of a refrigerator. First substance connector component 110 can be configured to transfer or receive a single substance or multiple substances.
First substance connector component 110 may include a mechanically actuated service switch 116, described below, which can be selectively actuated to establish a substance pathway between first substance communicating device 102 and second substance communicating device 104 when second substance communicating device 104 is coupled to first substance communicating device 102. In addition, first substance connector component 110 and second substance connector component 112 may also provide a mechanism, described below, for mechanically securing second substance communicating device 104 to first substance communicating device 102.
Service switch 116 may be enclosed within a housing, such as housing 114. Service switch 116 includes a switch plate 118 movable between an open position (see
First substance connector component 110 may include a substance communication line 120 operable for facilitating transfer of a substance to and from first substance communicating device 102. For purposes of discussion, substance communication line 120 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 will likely vary depending, at least in part, on the type of substance being transferred, the pressure at which the substance is being transferred and manufacturing considerations. It shall be appreciated that substance communication line 120 may include other configurations to accommodate various design considerations.
As best shown generally in
A proximity sensor, such as electrical contacts 132, may be provided in housing 114 and extend into passageway 130 to sense the position of substance communication line 120. For example, housing 114 may be made of dielectric material and electrical contacts 132 may be spaced apart rings of conductive material molded into housing 114. Each of the contacts 132 may be connected by an electrical line 134 to a control circuit, not shown, responsive to the creation of an electrical connection between contacts 132 to operate a flow regulating component 136, which is capable of selectively inhibiting the flow of substance from substance provider 124 to substance communication line 120. Flow regulating component 136 may more specifically be a substance flow regulating component, such as a pump.
A proximity target, such as a conductive surface 140 formed on the exterior of substance communication line 120, is selectively engageable with the electrical contacts 132 to complete a circuit between the electrical contacts 132 and thereby permit the proximity sensor to detect the repositioning of substance communication line 120 in the passageway 130 and operate flow regulating component 136. Substance communication line 120 may be formed of a dielectric material and conductive surface 140 may be formed from a conductive foil or coating applied to the exterior surface of substance communication line 120 or a conductive ring molded into substance communication line 120.
The distal end 142 of substance communication line 120 may be tapered outwardly and cooperates with a chamfered open end 144 of passageway 130 opening to the exterior of housing 114 to restrict the removal of substance communication line 120 from passageway 130. Distal end 142 of substance communication line 120 forms a receptacle able to operably engage a corresponding substance terminal of second substance communicating device 104, described below, when the second substance communicating device 104 is coupled to first substance communicating device 102. It will be appreciated that portions of housing 114 cooperate with the distal end 142 of substance communication line 120 to define a receptacle for coupling with a plug, described below.
Switch plate 118 is slidably mounted to at least one guide rod 146. As illustrated herein, switch plate 118 is mounted to a pair of spaced guide rods 146. An end 148 of each guide rod 146 can be fixedly attached to housing 114. An opposite end of each guide rod 146 may include a stop 150, which can be sized larger than the opposite end to prevent switch plate 118 from traveling past the stop 150. A biasing member 152 may be disposed between housing 114 and switch plate 118 to urge switch plate 118 toward stop 150. As illustrated herein, two biasing members 152 in the form of springs are disposed about guide rods 146.
Service switch 116 further includes at least one actuating link 154 fixedly attached to switch plate 118 at one end 156 of actuating link 154. Actuating link 154 extends from switch plate 118 through an aperture 160 in housing 114 and has a hook-shaped portion 158 disposed at its distal end outside of the housing 114. Hook-shaped portion 158 allows actuating link 154 to selectively connect to a corresponding actuating link 174, described below, associated with second substance communicating device 104. Sufficient clearance is provided between actuating link 154 and aperture 160 to allow actuating link 154 to move freely in and out of the housing and thereby move switch plate 118 to move substance communication line 120 along aperture 128. First actuating link 154 may be constructed of a flexible material having a relatively high modulus of elasticity, such as spring steel, or another generally flexible material having similar mechanical properties.
Second substance connector component 112 can be integrally formed with second substance communicating device 104 or may be an add-on component. As described above, it may be directly integrated into an accessory device or instead integrated into an adapter to which an accessory device is in turn mounted. For purposes of discussion, second substance connector component 112 is shown integrally formed with second substance communicating device 104. When configured as an add-on component, second substance connector component 112 may also function as an adapter to enable a host and a portable device having dissimilar substance communication connector systems to be indirectly coupled to one another. Second substance connector component 112 may be removable or non-removable from second substance communicating device 104. Second substance connector component 112 may be configured to transfer or receive a single substance or multiple substances and may also be configured to transfer additional services such as electrical power, mechanical power, data, illumination, sound or heat.
Second substance connector component 112 may be enclosed within a housing 164. Housing 164 may be an integral part of second substance communicating device 104 or may be a separate component. For purposes of discussion, housing 164 is illustrated as an integral part of second substance communicating device 104.
Second substance connector component 112 may include a substance communication line 166 operable for transferring a substance to and from second substance communicating device 104. For purposes of discussion, substance communication line 166 is illustrated generically in
Substance communication line 166 is in communication at one end with a substance consumer 168. Substance communication line 166 is fitted through an aperture 170 in housing 164 and terminates in an exposed end 172 disposed outside of housing 164. Substance communication line 166 is fastened, secured or molded into housing 164 so as to move with housing 164. It will be appreciated that the exposed end 172 of substance communication line 166 cooperates with portions of housing 164 to form a plug engageable with a receptacle formed by the cooperation of housing 114 with the distal end 142 of substance communication line 120.
Second substance connector component 112 may include at least one second actuating link 174 that can connect to first actuating link 154 of first substance connector component 110 when second substance communicating device 104 is coupled to first substance communicating device 102. Second actuating link 174 may include a hook-shaped portion 176 that can be coupled to the corresponding hook-shaped potion 158 of first actuating link 154. An opposite end 178 of second actuating link 174 can be operably connected to a switch component such as toggle switch 180, or similar device. Toggle switch 180 can be moved between an unlatched position, shown in
It will be appreciated that first substance connector component 110 and second substance connector component 112 may include various geometric features to facilitate coupling of second substance communicating device 104 to first substance communicating device 102. For example, first substance connector component 110 may include a raised boss 190 that can engage a corresponding recess 192 of second substance connector component 112. A raised ridge 184 at least partially defines an outer boundary of recess 192. Alignment features such as boss 190 and recess 192 may assist with positioning of second substance connector component 112 relative to first substance connector component 110 prior to engagement, and may also function to minimizing lateral movement of second substance communicating device 104 relative to first substance communicating device 102 when first substance connector component 110 is coupled to second substance connector component 112. It shall be appreciated, however, that the illustrated configuration is merely one example of the type of features that may be incorporated into first substance connector component 110 and second substance connector component 112 to aide alignment and coupling of second substance communicating device 104 to first substance communicating device 102. In practice, other configurations may also be employed to accommodate various design considerations of a particular application.
To facilitate coupling and decoupling of second actuating link 174 with first actuating link 154, second actuating link 174 can be offset laterally relative to first actuating link 154 to allow hook-shaped portion 176 of second actuating link 174 to clear hook-shaped portion 158 of the first actuating link 154 when second substance communicating device 104 is attached to first substance communicating device 102. For example, referring particularly to
Actuating link 174 and/or toggle switch 180 may, alone or in combination with each other or with actuating link 154, be considered to be an actuator engageable with the service switch 116 for actuating the service switch 116 and establishing a substance pathway between first substance communicating device 102 and second substance communicating device 104.
The process is reversed when disengaging second substance communicating device 104 from first substance communicating device 102. As first substance connector component 110 is disengaged from second substance connector component 112, hook-shaped portion 158 of actuation link 154 slides along inclined surface 182 and is moved out of alignment with hooked-shaped portion 176 of second actuating link 174, as shown in
Coupling of second substance communicating device 104 to first substance communicating device 102 can be accomplished by positioning second substance communicating device 104 adjacent first substance communicating device 102 in such a manner that first substance connector component 110 is generally aligned with second substance connector component 112, as shown in
Service switch 116 can be activated by moving toggle switch 180 to the latched position, as shown in
Furthermore, as substance communication line 120 is advanced into engagement with substance communication line 166, the proximity sensor, represented by electrical contacts 132 on the inner walls of passageway 130 is engaged by the proximity target, represented by the conductive surface 140 on the outer walls of the passageway 130 to complete a circuit and permit flow regulating component 136 to open and permit the flow of substance from the substance provider 124.
It should be noted that service switch 116 is intended to selectively permit and inhibit flow of substance from the substance provider 124 to the substance communication line 120 based on the presence of a proximity target associated with substance communication line 120. Alternative sensors and targets may be used for this purpose. It should further be noted that the proximity sensor is intended to deliver a signal or message selectively permitting or selectively inhibiting the flow of substance to substance communication line 120 and that the signal represented in the drawings and described above as the completion of an electrical circuit is merely one example of various signals or messages that may be used for this purpose. It should also be noted that additional valves and controls, besides those represented in the drawings and described herein, may be provided to further regulate the flow of substance based on the needs of the user of the second substance communicating device 104.
Service switch 116 can be deactivated by moving toggle switch 180 from the latched position, as shown in
Once toggle switch 180 has been moved to the unlatched position, second substance communicating device 104 can be removed from first substance communicating device 102 by withdrawing second substance communicating device 104 from first substance communicating device 102 along a path generally parallel to the path defined by arrow 186. Furthermore, as substance communication line 120 is retracted from engagement with substance communication line 166, the proximity sensor, acts to inhibit flow regulating component 136 from opening to permit the flow of substance from the substance provider 124.
Referring to
To avoid confusion, please note that the second substance communicating device 104′ is shown below the first substance communicating device 102′ in
First and second substance connector components 110′ and 112′ are respectively incorporated into first and second substance communicating devices 102′ and 104′. First substance communicating device 102′ has a substance provider 124′ connected by a first substance line 200 through a first flow regulating component 136′, such as a switching valve or a pump, to a second substance line 204 terminating in an exposed end 210. Exposed end 210 of second substance line 204 acts as a substance interface for first substance connector components 110′. Second substance communicating device 104′ has a substance consumer 168′ connected to a substance line 120′ extending through an aperture 128′ in a switch plate 118′ and a passageway 130′ in a housing 164′ of second substance communicating device 104′ and terminating at an exposed end 142′. Exposed end 142′ of substance line 120′ acts as a substance interface for second substance connector components 112′ and is engageable with the exposed end 210 of second substance line 204 for selectively establishing a substance pathway over which desired substances may be transferred between the first substance communicating device 102′ and the second substance communicating device 104′.
Second substance communicating device 104′ has a mechanically actuated service switch 116′ having a switch plate 118′ movable between a lower position, as shown, and a raised position, not shown, by operation of toggle switches 180′ in a similar manner to that described above with reference to service switch 116 shown in
Actuating link 174′ and/or toggle switch 180′ may, alone or in combination with each other or with actuating link 154′, be considered to be an actuator engageable with the service switch 116′ for actuating the service switch 116′ and establishing a substance pathway between first substance communicating device 102′ and second substance communicating device 104′.
First substance communicating device 102′ further has a first electromagnetic connector component 222 and second substance communicating device 104′ has a second electromagnetic connector component 224. First and second electromagnetic connector components 222 and 224 have complementary configurations that enable the electromagnetic connector components to be coupled to one another, thereby establishing a electrical pathway over which power or data may be transferred between first substance communicating device 102′ and second substance communicating device 104′. It will be appreciated that wired power, wireless power, wired data, or wireless data may be communicated between the electromagnetic connector components 222 and 224. Together, first and second electromagnetic connector components 222 and 224 comprise an electromagnetic communication coupling system.
First electromagnetic connector component 222 may be enclosed within housing 114′ of first substance communicating device 102′. First electromagnetic connector component 222 may be removable or non-removable from first substance communicating device 102′. First electromagnetic connector component 222 may be configured to transfer or receive power, data or both.
First electromagnetic connector component 222 may be connected by electrical lines 216 to a controller 218 which in turn may be connected by electrical lines 220 to flow regulating component 136′. Controller 218 may control the operation of flow regulating component 136′ in response to an electrical service received by first electromagnetic connector component 222. Alternatively, controller 218 may be omitted and electrical lines 220 may be directly coupled to electrical lines 216, whereby flow regulating component 136′ may be directly regulated by an electrical power or data signal, which may be communicated through first electromagnetic connector component 222 when connected to second electromagnetic connector component 224.
Second electromagnetic connector component 224 may be enclosed within housing 164′ of second substance communicating device 104′. Second electromagnetic connector component 224 may be removable or non-removable from second substance communicating device 104′. Second electromagnetic connector component 224 may be configured to transfer or receive power, data or both. Second electromagnetic connector component 224 may be provided with a biasing member 240 biasing second electromagnetic connector component 224 away from housing 164′ to facilitate a reliable connection with a first electromagnetic connector component 222.
Second electromagnetic connector component 224 may be connected by electrical lines 230 to a controller 228 configured to selectively permit the communication of electromagnetic service through second electromagnetic connector component 224. In a first embodiment, controller 228 is connected by electrical lines 226 to contacts 132′ and by electrical line 230 to second electromagnetic connector component 224 to provide an electromagnetic service in the form of data or power to second electromagnetic connector component 224 when substance line 120′ is raised sufficiently to provide an electrical path along surface 140′ between contacts 132′. Controller 228 may then control the communication of data and power along lines 216 in response to this signal by switching power on or off from a power supply, not shown, or by providing a data signal to lines 230. Surface 140′ cooperates with contacts 132′ to act as a switch, and controller 228 may, in response to the detection of the closing of that switch, control the communication of data and power to second electromagnetic connector component 224.
Alternatively, controller 228 may provide a control voltage on one of the electrical lines of 226 and may include sensing, such as current flow sensing, so that when surface 140′ creates continuity and a circuit is formed between controller 228, electrical lines 226, contacts 132′ and surface 140′, a control signal may be generated and used to control the communication of data and power to second electromagnetic connector component 224.
Alternatively, controller 228 may provide a power or data to second electromagnetic connector component 224 at other times, but may also provide a signal indicative of the displacement of the substance line 120′.
Alternatively, electrical line 230 may be directly connected to lines 226 so as to directly supply an electromagnetic service of power and/or data to second electromagnetic connector component 224 from a power supply, not shown, in electrical series with the contacts 132′. In this embodiment, substance line 120′ acts directly as a power switch to directly permit the flow of electromagnetic service through second electromagnetic connector component 224.
Still another alternative omits controller 228 and the power supply, not shown, from communication with these components and instead connects 132′ directly with second electromagnetic connector component 224 as an unpowered connection. In this alternative configuration, controller 218 in the first substance communicating device 102′ detects the proper positioning of substance line 120′ by detecting the closing of a circuit including electrical lines 216, 230 and 226, which will only occur when the first and second electromagnetic connector components 222 and 224 are coupled and substance line 120′ has been raised.
Alternatively, or additionally, lines 226 may be directly or indirectly connected, such as by electrical lines 246, to a controller 234 for controlling substance consumer 168′. Controller 234 may, in turn, be connected to substance consumer 168′ by electrical lines 248. Controller 234 may control substance consumer 168′ in response to this signal. In this embodiment, controller 234 may also regulate the communication of service to first electromagnetic connector component 222. Controller 234 may also communicate with controllers 218 or 228 to regulate the integrated operation of first and second substance communicating devices 102′ and 104′.
In still another alternative, not shown, second electromagnetic connector component 224 is coupled to switch plate 118′ so that second electromagnetic connector component 224 may be raised into engagement with first electromagnetic connector component 222 by operation of toggle switches 180′.
In yet another alternative, not shown, either controller 218 or 228 may be omitted and the other controller 228 or 218 may regulate the communication of power or data between the first and second substance communicating devices 102′ and 104′.
In yet another alternative, not shown, surface 140′ could be a proximity target and a proximity sensor could be associated with line 204 in substance communicating device 102′ such that when substance lines 120′ and 204 inter-engage, the proximity sensor is triggered by the proximity target resulting in control signal communication between the proximity sensor and the flow regulating device 136′, thereby using an actuator, such as toggle switches 180′, to selectively permit substance communication between the first and second substance communicating devices 102′ and 104′.
Flow regulating component 136′, which may be a normally closed valve requiring power to be opened or a pump requiring power to operate, acts to prevent the communication of substance from first substance communicating device 102′. Similarly, another type of normally open proximity switch may be substituted for contacts 132′ and surface 140′ for controlling the communication of electromagnetic service through first and second electromagnetic connector components 222 and 224, which, in turn, is used to control the communication of substance through first and second substance connector components 110′ and 112′.
For some implementations, controller 234 may selectively operate second flow regulating component, not shown, associated with substance consumer 168′ in response to one of the switching alternatives described above. Controllers 218, 228 and 234 may be embodied in a plurality of designs and configurations. In one configuration, any or all of controllers 218, 228 and 234 may include relays with one or more contacts pairs for wiring auxiliary circuits where the continuity of the circuit is determined by the state of the relay coil being either energized or de-energized. In another configuration, any or all of controllers 218, 228 and 234 may include micro-processors with appropriate signal conditioning circuitry for electrically interfacing with other electrical components. In addition, there are many system design options for controllers 218, 228 and 234. In some cases one or more elements of 218, 228, and 224 or their sub-elements may be eliminated, substituted, or combined to accomplish the selective substance communication between the first and second substance communicating devices 102′ and 104′.
It will be appreciated that in implementations where controllers 218, 228, and/or 234 are used, these controllers form a part of the system software architecture and electronics 15 described above with reference to
