TECHNICAL FIELD

The present invention relates to a beverage or foodstuff preparation machine and in particular to a user interface for control of said machine. BACKGROUND

Increasingly machines for the preparation of a beverage or foodstuff are configured to operate using a container that comprises a single-serving of a beverage or foodstuff material, e.g. coffee, tea, ice cream, yoghurt. The machine may be configured for preparation by processing said material in the container, e.g. with the addition of fluid, such as milk or water, and the application of mixing thereto, such a machine is disclosed in PCT/EP 13/072692. Alternatively, the machine may be configured for preparation by at least partially extracting an ingredient of the material from the container, e.g. by dissolution or brewing, and expelling it into a receptacle for end user consumption. Examples of the latter such machines are provided in EP 2393404 A1 , EP 2470053 A1 , WO 2009/1 13035.

The increased popularity of these machines may be partly attributed to enhanced user convenience compared to a conventional machine, e.g. compared to a manually operated coffee maker such as a stove-top espresso maker or cafetiere (French press).

In particular the aforesaid machines comprise: a component processing unit, which is operable to process the said material via the application of a fluid (typically water) to the desired beverage or foodstuff; and a control system to control the component processing unit to execute a preparation process. The control system is generally operable to execute numerous different preparation processes that comprise recipes for preparing the beverage or foodstuff according to user preference. Accordingly the control system comprises a user interface for user selection of the preparation process.

Often a user operates such machines in conjunction with auxiliary components which provide additional functionality and thus the option for further preparation processes. Taking a coffee machine as an example, the beverage machine is typically operable to prepare different coffee types based on the addition of water, e.g. ristretto, lungo, and a suitable auxiliary component may comprise a milk processing unit. The milk processing unit provides the option of further preparation processes that comprise the addition of milk e.g. cappuccino, late. It is desirable to have such a configuration of machine since a user can purchase the basic machine and add functionality when available/desired or when the finances of the user permit.

Accordingly it is desirable to provide a user with the option of selecting these new preparation processes. One solution as provided for in the Dehlongi Lattissima Pro, model number EN750.MB beverage machine, wherein the control system on a coffee machine is configured to detect an auxiliary product in the form of a milk processing unit and to control a graphical user interface on the machine. In particular the machine comprises a docking interface for docking with part of the milk processing unit. The control system comprises an electrical switch to detect said docking and to provide a signal in the form of closing or opening of a circuit. The control of the graphical user interface comprises the illumination of icons at predetermined positions on the user interface, whereby the icons are selectable by a user to execute the additional preparation processes associated with the milk processing unit. A drawback of such an arrangement is that it cannot be easily adapted to enable operation of the machine with further auxiliary components. A yet further drawback is that the graphical user interface cannot be adapted to incorporate the option of selection of new preparation processes.

Thus in spite of the considerable effort already invested in the development of said control systems and the associated user interfaces further improvements are desirable. SUMMARY OF THE INVENTION

An object of the invention is to provide a beverage or foodstuff preparation machine which is expandable such that it can operate with a range of auxiliary components.

In particular it would be advantageous to provide a control system of such a machine that comprises a user interface that can interface with a range of different auxiliary components. It would be advantageous to provide such a user interface that is cosmetically appealing.

It would be advantageous to provide such a control system that is cost effective.

It would be advantageous to provide such a control system that is convenient to operate.

Objects of the invention are achieved by: the beverage or foodstuff preparation machine according to claim 1 ; the auxiliary component according to claim 13; the system according to claim 14; and the method according to claim 15.

Disclosed herein according to a first aspect of the invention is a beverage or foodstuff preparation machine comprising a component processing unit to process a beverage or foodstuff component to prepare a beverage or foodstuff therefrom and an auxiliary component interface; and an auxiliary component interface. The machine further comprising a control system operable to execute a preparation process comprising (i.e. as part of said process) control of said component processing unit to prepare the beverage or foodstuff. The control system comprising a user interface to receive a user selection of a preparation process and further comprising a communication interface of the auxiliary component interface to receive auxiliary component information stored on an auxiliary component. The control system operable to: receive said auxiliary component information from an auxiliary component; and enable, using the auxiliary component information, a user to select via the user interface one or more preparation processes that at least partially utilise the auxiliary component (i.e. in combination with the component processing unit).

Accordingly an object of the invention is solved since the beverage or foodstuff machine is expandable such that it can operate with a range of auxiliary components. In particular information, i.e. data, is transferred to the said machine from the auxiliary component and is processed by said machine to enable a user to select on the machine a preparation process that comprises control of the auxiliary component. The machine is therefore not restricted to operation with a limited list of known auxiliary components. As new auxiliary components become available (or as existing components are updated) the machine can adapt to operate with them by receiving information specific to the auxiliary component and processing this information to adapt the machine accordingly.

The control system is preferably operable to: use the auxiliary component information to reconfigure (e.g. adjust, restructure) the user interface to enable a user to select (e.g. via an icon) one or more preparation processes that at least partially utilise the auxiliary component.

The control system is preferably programmable using the auxiliary component information to control the component processing unit to be operable to execute the one or more processes that at least partially utilise the auxiliary component. Typically a memory unit associated with a processor of the control system can have executable programs related to the process stored thereon.

The control system may comprise a processor operatively connected to the: user interface; the auxiliary component interface; component processing unit. The user interface may be reconfigured by instructions sent from the processor to the user interface. The control system may be programmable by the storage on a memory unit associated with the processor of preparation process that comprises control of the auxiliary component.

To indicate the available processes to a user the user interface may comprise an output unit. The output unit may comprise a display such as a graphic or character liquid crystal display (LCD) or light emitting diode (LED) display. The output unit may indicate the available processes to a user: by an icon that may represent a process, the icon may be illuminable; an LED that may comprise or have associated therewith indicia that represent a process. To enable a user to select processes the user interface may comprise an input unit. The input unit may comprise buttons or touch sensing or screen edge buttons associated with the display (i.e. for selection of said icons).

The auxiliary component information may comprise information to enable the identification of the auxiliary component from other such auxiliary components. It may for example comprise an identifier such as a numeric or alpha numeric identifier. The identifier may be used to identify the configuration of the user interface and/or information to program one or more preparation processes that use the auxiliary component. Said use of the information may comprise accessing a database on the machine and/or on a remote resource (e.g. if not in the machine). The database may be accessed via a key value database type, such as a lookup table. The auxiliary component information may comprise information to reconfigure the user interface. In such an example the aforesaid identifier may additionally be used to obtain information to program one or more preparation processes. The auxiliary component information may comprise information to program one or more preparation processes that use the auxiliary component. In such an example the aforesaid identifier may additionally be used to obtain information to reconfigure the user interface. The communication interface of the auxiliary component interface is for data transfer. The communication interface may comprise a wireless communication interface and is generally operable to transmit and receive wireless signals by a radio. It may be at least one selected from a group consisting of: a wireless local area network interface such as described in the Institute of Electronics Engineers (IEEE) 802.11 standard; Bluetooth™ from the Bluetooth Special Interest Group of Kirkland Wash; a reader for interface with a radio frequency identifier (RFID) tag; and optional further wireless interfaces such as a near field communication interface. Alternatively the communication interface may comprise a wired communication interface, such as at least one selected from a group consisting of: RS-232; USB; l ² C; wired local area network interface such as described in the Institute of Electronics Engineers (IEEE) 802.3 standard. The wired communication interface may also be operable to supply power to the auxiliary component, e.g. from its own power supply unit (PSU), i.e. the communication interface comprises power-line communication (PLC). The latter configuration is advantageous since a separate PSU and corresponding connection to the mains electrical supply is thus obviated for the auxiliary component. To enable the beverage or foodstuff preparation machine to connect with and thus operate with more than one auxiliary component at a given instant there may be: more than one communication interface, i.e. a plurality of those selected from either of the above lists; a single communication interface configured for concurrent connection with more than one auxiliary component (e.g. the machine acts as a server with the auxiliary components as clients, whereby a client may by assigned a port). The communication interface of the auxiliary component interface may be a bidirectional interface. A bidirectional interface may be used to determine whether the auxiliary component is still in communication with the beverage or foodstuff preparation machine. As an example messages may be periodically sent from the auxiliary component to said machine. If a message is not received within a specified time interval then at timeout the auxiliary component may be determined as disconnected. Alternatively the message may be sent as part of an invocation and response process. The message may comprise the identifier. A bidirectional interface may be used as part of the control system controlling the auxiliary component over the auxiliary component. In particular a preparation process can comprise the control system of the beverage or foodstuff machine controlling the auxiliary component over the auxiliary component interface and receiving feedback from the auxiliary component with respect to said control. The feedback may comprise a message communicating the completion of an instructed process, e.g.: for an auxiliary component that comprises a milk processing unit the process may be the supply of a defined quantity of frothed and heated milk to a receptacle; for an auxiliary component that comprises an auxiliary product unit the process may be the supply of a layer such as syrup in between or after coffee and/or milk layers. The process that at least partially utilises the auxiliary component may comprise the control system controlling one or more auxiliary components (e.g. an auxiliary processing unit of the or each auxiliary components) via the communication interface of the auxiliary component interface (e.g. by transferring process information to a control system of the or each auxiliary component). In particular the control system may be configured to control the component processing unit and auxiliary component concurrently and/or sequentially. In the instance of sequential operation layers of component from the beverage or foodstuff machine and the auxiliary component may be alternatively dispensed. In the instance or concurrent operation a layer comprising both components may be dispensed. The process that at least partially utilises the auxiliary component may comprise providing instructions to an end user via the user interface for end user control of the auxiliary component.

The control system of the machine may be operable to: determine when an auxiliary component is removed from data communication with the communication interface of the auxiliary component interface; and to disable the user selection via the user interface of the one or more preparation processes that at least partially utilise the auxiliary component.

In the example of a wireless communication interface of the auxiliary component interface, the beverage or foodstuff preparation machine may be operable to receive said information without physically docking with an auxiliary component. Alternatively for both wireless and wired communication interfaces the auxiliary component interface may further comprise a docking interface for physically docking (e.g. removably docking) an auxiliary component with the machine. The docking interface preferably comprises a first interface portion arranged on said machine dockable with a second interface portion arranged on the auxiliary component. The docking interface is preferably configured such that: an outlet and/or output of an auxiliary processing unit of a docked auxiliary component is arranged to supply an auxiliary product or apply an auxiliary process to a foodstuff or beverage preferably in a receptacle. The control system of the machine may be operable to: receive said auxiliary component information from a plurality of auxiliary components; and to enable using the auxiliary component information a user to select via the user interface one or more preparation processes that at least partially utilise each (e.g. a plurality of processes which each use a different auxiliary component) and/or a combination (e.g. processes that use more than one auxiliary component) of the auxiliary components. In particular information from one or more subsequent auxiliary components can be received and utilised when one or more auxiliary components are operatively connected to the beverage or foodstuff preparation machine. The control system may be operable to reconfigure the user interface to enable a user to select one or more preparation processes that at least partially utilise each and/or a combination of the auxiliary components. In particular the user interface may be reconfigured to display auxiliary one or more auxiliary icons at the same time for the selection of processes that use one or a combination of different auxiliary components. The control system may be programmable to execute the one or more processes that at least partially utilise each and/or a combination of the auxiliary components.

The control system may be operable to use the received auxiliary component information to; retrieve user interface configuration information and preferably to reconfigure said interface using the retrieved user interface configuration information; and/or retrieve process information (i.e. information for processes that at least partially utilise the auxiliary component) and preferably to enable operation of a process using the retrieved process information. The aforesaid information may be at least partially retrieved from the machine itself, e.g. it is retrieved from a memory associated with the processor preferably using a lookup table. The aforesaid information may be at least partially retrieved from a remote resource via a communication interface (e.g. the same interface as the auxiliary component interface or an additional communication interface) of the machine. The communication interface is configured for communication over a network such as the internet or the cellular network. The remote resource is typically arranged remote from the beverage of foodstuff preparation machine, e.g. at a different location. The remote resource may comprise a server which is embodied as hardware and/or software. Alternatively it may comprise a peer to peer network or other distributed system. The control system of the machine may be operable to determine if said user interface configuration information and/or process information is stored on the machine and if not then to obtain said information from the remote resource. It may also be configured to store the information retrieved from the remote resource locally on the machine. In this way it does not have to be obtained from the remote resource again.

The control system of the machine may be operable to reconfigure the user interface by displaying an auxiliary icon to select the process that at least partially utilises the auxiliary component. The auxiliary icon is preferably displayed with indicia to indicate said process. A plurality of auxiliary icons each of which are to select said processes may be disposed about a periphery of one or a group of main icons, the main icons to select processes that are executed entirely on the beverage or foodstuff machine. The main icons may remain in the same position when the or each auxiliary icons are displayed. The periphery may be about a circumferentially extending line, which extends around the or each main icon. The periphery may be along a side edge of main icons. Alternatively the control system of the machine may be operable to configure the user interface by activating a light source such as an LED related to the process that at least partially utilises the auxiliary component.

The component processing unit generally is operable perform said preparation by the addition of fluid, such as water or milk to the beverage or foodstuff material. The component processing unit may comprise one of an: an extraction unit; a dissolution unit; a mixing unit. The component processing unit may further comprise a fluid supply that is operable to supply fluid to the aforesaid unit. Generally the fluid supply comprises a fluid pump and a fluid heater. The aforesaid units may be configured for operation with a container containing beverage or foodstuff material.

The container is for use (e.g. it is suitably dimensioned) by a beverage or foodstuff preparation machine. The container for containing beverage or foodstuff material (e.g. it has an internal volume and may be food safe). The container may be a single-serving container, i.e. it is dimensioned for containing a dosage of beverage or foodstuff material for preparation of a single serving (e.g. pre portioned) of said product. The container may be a single-use container, i.e. it is intended to be used in a single preparation process after which it is preferably rendered unusable, e.g. by perforation, penetration, removal of a lid or exhaustion of said material. The container may comprise the beverage or foodstuff material contained therein. The container may comprise one of the following: capsule; packet; receptacle for end user consumption of the beverage or foodstuff therefrom. The capsule may have an internal volume of 5 - 80 ml. The receptacle may have an internal volume of 150 - 350 ml. The packet may have an internal volume of 150 - 350 ml or 200 - 300 ml or 50 - 150 depending on the application.

The auxiliary product unit comprises: a reservoir to store said product; an electrically operated dispensing system to effect the dispensing of said product from the reservoir. The thermal exchanger is operable to transfer and/or extract thermal energy from the receptacle. In an example of transfer of thermal energy it may comprise a heater such as thermo block. In an example of extraction of thermal energy it may comprise heat pump such as a refrigeration-type cycle heat pump.

The receptacle support is operable to support the container during a preparation process such that the container remains stationary during agitation of the material therein by the agitator unit. The receptacle support preferably is thermally associated with the thermal exchanger such that transfer of thermal energy can occur with a supported receptacle.

In a variant of the above, the component processing unit 14 further comprises a dispensing mechanism for receiving a container 6 (such as a packet) and dispensing the associated material into the receptacle, where it is prepared. Such an example is disclosed in EP 14167344 A, which is incorporated herein by reference.

In a further variant of the above, the mixing unit comprises a dispensing mechanism operable to dispense from a reservoir a single serving of the associated material into the receptacle, where it is prepared and/or to prepare the material in situ before dispensing into the receptacle. Such an example is disclosed in WO 2010/034722 and in WO 2013/014142, which are incorporated herein by reference. Control System General

The control system 16, an example of which is illustrated in figure 2, is operable to control the component processing unit 14 to execute a preparation process, which comprises the preparation of the beverage/foodstuff. The control system 16 typically comprises: a user interface 36; a processor 38; optional sensors 40; an optional communication interface 48; a power supply 42, which are described sequentially.

The user interface 32 comprises hardware to enable an end user to interface with the processor 38 and hence is operatively connected thereto. To indicate the available processes to a user the user interface comprises an output unit. The output unit may comprise at least one selected from a group consisting of: a display such as a graphic or character liquid crystal display (LCD); light emitting diode (LED) display; LEDs which have indicia associated therewith. The output unit indicates the available preparation processes to a user, e.g. by one or more icons that represents a process; by one or more LEDs that may comprise or have associated therewith indicia that represent the process. To enable a user to select preparation processes the user interface comprises an input unit. The input unit may comprise: buttons or touch sensing or screen edge buttons associated with the display; buttons associated with LEDs. Commands related to the selection of a preparation process are transferred from the input unit to the processor 38 as a user interface signal. The user interface may comprise a separate processing unit (examples of which are provided below) to control the interface hardware which is operatively connected to the maser processor 38. Optional sensors 40 are operatively connected to the processor 38 to provide an input for monitoring said process. The sensors 40 typically comprise one or more of the following: fluid temperature sensors; fluid level sensors; position sensors e.g. for sensing a position of the extraction unit 26; flow rate and/or volume sensors.

The processor 38 is generally operable to: receive an input, i.e. said commands from the user interface 36 and/or from the sensors 40; process the input according to program code stored on a memory unit (or as programed logic); provide an output, which is generally the said preparation process. The process may be executed with open-loop control, or more preferably with closed-loop control using the input signal from the sensors 40 as feedback. The processor 38 generally comprises memory, input and output system components, which are arranged as an integrated circuit, typically as a microprocessor or a microcontroller. The processor 38 may comprise other suitable integrated circuits, such as: an ASIC; a programmable logic device such as an FPGA; an analogue integrated circuit such as a controller. The processor 38 may also comprise one or more of the aforementioned integrated circuits, i.e. multiple processors. The processor 38 generally comprises a memory unit 46 for storage of the program code (such as preparation programs executable for a preparation process) and optionally data. The memory unit 46 typically comprises: a non-volatile memory e.g. EPROM, EEPROM or Flash for program code and operating parameter storage; volatile memory (RAM) for data storage. The memory unit may comprise separate and/or integrated (e.g. on a die of the processor) memory. Typically the processor 38 comprises a clock for timing of the preparation process (and for execution of instructions). The communication interface 48 is for data communication between the preparation machine 4 and a remote resource. The communication interface 48 can be used to supply and/or receive information related to an auxiliary component as will be discussed. The communication interface 48 can be configured for cabled media or wireless media or a combination thereof, e.g.: a wired connection, such as RS-232, USB, l ² C, Ethernet defined by IEEE 802.3; a wireless connection, such as wireless LAN (e.g. IEEE 802.11 ) or near field communication (NFC) or a cellular system such as GPRS or GSM. The communication interface 48 is operatively connected to the processor 38. Generally the communication interface comprises a separate processing unit (examples of which are provided above) to control communication hardware (e.g. an antenna) to interface with the maser processor 38. However, less complex configurations can be used e.g. a simple wired connection for serial communication directly with the processor 38.

The power supply 42 is operable to supply electrical energy to the processor 38 and component processing unit 14, and in particular the pump 22 as will be discussed. The power supply 42 may comprise various means, such as a battery or a unit to receive and condition a mains electrical supply. Remote Resource

The remote resource comprises a resource arranged distant (i.e. at a different location) to the machine 4. The remote resource comprises a database, such as a database server, operable to supply data (e.g. user interface and/or process data) to the machine. Typically the remote resource is a server system (e.g. embodied as hardware and/or software), a peer to peer network or other distributed system. The remote resource and machine 4 are in data communication with each other via a network such as the internet or the cellular network.

Auxiliary Component Interface

The auxiliary component interface 50 of the beverage or foodstuff preparation machine 4 is for interface with a corresponding interface of an auxiliary component 52. The auxiliary component interface 50 comprises a communication interface 62 (which may be configured for wired or wireless communication and is discussed in more detail later on) of the control system 16 and optional docking interface 54

For both wireless and wired communication interfaces 62 the beverage or foodstuff preparation machine may comprise a docking interface 54 for physically docking (e.g. removably docking) an auxiliary component 52 with the machine 4. The docking interface 54 preferably comprises a first interface portion arranged on said machine dockable with a second interface portion arranged on the auxiliary component. The first and second interface portions may be configured with at least one selected from a group consisting of: an interference (i.e. friction) fit; snap fit; resilient fastener fit. Generally one of the first or second interfaces are insertable into the other of the second of first interfaces such that the docking interface 54 acts to locate the auxiliary component 52 in a particular position. The docking interface 54 is preferably configured such that: an outlet and/or output of an auxiliary processing unit of a docked auxiliary component is arranged to supply an auxiliary product or apply an auxiliary process to a foodstuff or beverage preferably in a receptacle. Control System According to Invention

The control system 16 further comprises a communication interface 62 of the auxiliary component interface 50 of the machine 4. The communication interface 62 is configured to receive auxiliary component information stored on an auxiliary component 52, which will be discussed in more detail following. The control system 16 is operable to: receive said auxiliary component information from an auxiliary component; enable using the auxiliary component information a user to select via the user interface 36 one or more preparation processes that at least partially utilise the auxiliary component. Advantageously the beverage or foodstuff machine 4 is expandable such that it can operate with a range of auxiliary components, enabling a user to select on the machine a preparation process that comprises control of the auxiliary component.

The communication interface 62 is for data transfer. It may be combined with the aforedescribed communication interface 48 or be a separate interface as generally described herein. As such the communication interface 62 can be configured for cabled media or wireless media or a combination thereof. It is preferred that the communication interface 62 is a wireless communication interface and is generally operable to transmit and receive wireless signals by a radio. It may be at least one selected from a group consisting of: a wireless local area network interface such as described in the Institute of Electronics Engineers (IEEE) 802.11 standard; Bluetooth™ from the Bluetooth Special Interest Group of Kirkland Wash; and optional further wireless interfaces such as a near field communication interface and an RFID interface.

Examples of suitable wired communication interfaces 62 comprises at least one selected from a group consisting of: RS-232; USB; l ² C; wired local area network interface such as described in the Institute of Electronics Engineers (IEEE) 802.3 standard.

With a wireless communication interface 62 the machine 4 may be operable to receive said information without physically docking with an auxiliary component, thus the docking interface 54 of the auxiliary component interface 50 is obviated.

Figure 3 shows an example combination of the aforesaid configurations, wherein the machine 4 is for coffee preparation and the auxiliary component 52 is a milk processing unit. In particular the auxiliary component interface 50 comprises a wireless communication interface 62 in the form of a transceiver operable to send and receive radio signals to an RFID on the auxiliary component. Accordingly the auxiliary component information is transmitted via radio. The machine 4 is configured to physically dock with the auxiliary component 52, and thus the auxiliary component interface 50 comprises a docking interface 54 which is selected from one of the aforesaid configurations.

The aforesaid configuration of the control system 16 to enable using the auxiliary component information a user to select via the user interface 36 one or more preparation processes that at least partially utilise the auxiliary component may extend to various embodiments. In a first embodiment the control system 16 may assign a reserved portion of the user interface 36 to the new preparation process associated with the auxiliary component 52. For example, in response to the received auxiliary component information the selection of: a button associated with an LED; or icon on the display, is associated with a process that utilises the auxiliary component. In this way reconfiguration of the user interface is not specifically required.

In a second embodiment the control system 16 is programmable using the auxiliary component information to control the component processing unit 14 to be operable to execute the one or more processes that at least partially utilise the auxiliary component 52. Typically the memory unit 46 associated with a processor 38 of the control system can have executable programs related to the process stored thereon. In an example the control system may use the auxiliary component information to identify one or more preparation processes associated with the auxiliary component and to enable the execution of the process. In particular the or each process may be identified on the memory unit 46 associated with the processor 38 and enabled for execution. Alternatively information comprising the or each process may be obtained by the control system and stored for execution on the memory unit 46. In the latter case, the information may be obtained from a remote resource and/or from the auxiliary component information itself.

In a third embodiment the control system 16 is operable to: use the auxiliary component information to reconfigure (e.g. adjust) the user interface 36 to enable a user to select one or more preparation processes that at least partially utilise the auxiliary component 52. That is to say that the user interface is in some way changed in response to determination of the presence of the auxiliary component. The user interface may be reconfigured by the processor 38 controlling the user interface 32, e.g. instructions sent to a separate processor which controls a display or as an output signal from the processor 38 when driving a display directly.

The user interface 36 may be reconfigured in various ways depending of the configuration of the output unit, e.g.: by the display of an auxiliary icon or LED for each associated additional process that at least partially utilises the auxiliary component. The auxiliary icon is preferably illuminated and may comprise indicia to indicate said process. The indicia may comprise an illustration of the product produced by the process, e.g. a particular coffee type.

More particularly one or a plurality of main icons 56 that relate to preparation processes that are executed entirely on the beverage or foodstuff machine 4 may be arranged in a first group and one or a plurality of auxiliary icons 58 which are associated with to process at least partially utilises the auxiliary component may be arranged in a second group. Generally the first group is arranged in a fixed position, i.e. it does not move with the addition of the second group. The second group may be disposed about a periphery of the first group. Advantageously there is more space for icons relating to numerous preparation processes (which may be associated with a single of multiple auxiliary components). The aforesaid periphery may comprise an entire periphery or partial periphery, such as a side edge.

Figure 4A shows an example of the above, wherein there is a single main icon 56 as the first group and there are 5 auxiliary icons 58 circumferentially disposed about the main icon. In particular the main icon 56 is for selection of a preparation process that comprises a coffee without milk and the 5 auxiliary icons are for selection of preparation processes that comprise utilisation of one or more auxiliary components: e.g.: latte; cappuccino; cold coffee; layered combinations of coffee and milk etc. It will be appreciated that the example of figure 4A may be extended to comprise any number of auxiliary icons and any number of main icons (and for various machine and auxiliary component types). In the example of a plurality of main icons they can be arranged in a configuration to define a centre point about which the auxiliary icons are disposed. The configuration may comprise a polygon (such as a triangle, square or hexagon) with the centre point arranged at the centre and the auxiliary icons arranged at the vertices. In another specific example of the above the auxiliary icons may be disposed as a rectangle about one of more main icons.

Figure 4B shows an example of the above, wherein there are three main icons 56 as the first group and there are 3 auxiliary icons 58 peripherally disposed along a side edge of the main icons. In particular the main icons 56 are for selection of preparation processes that comprises a coffee without milk of three different sizes and the 3 auxiliary icons are for selection of preparation processes that comprises utilisation of one or more auxiliary components: latte; cappuccino; a cooled coffee. It will be appreciated that the example of figure 4B may be extended to comprise any number of auxiliary icons and any number of main icons (and for various machine and auxiliary component types).

The aforesaid first - third embodiments may be suitably combined, e.g. the second and third embodiment or the first and third embodiment or the first and second embodiment. In view of the above first - third embodiments the auxiliary component information sent from the auxiliary component 52 and received on the machine 4 may comprise different quantities depending on the configuration of the system 2, which are discussed following.

In a first example the auxiliary component information may comprise information to enable the identification of the auxiliary component from other such auxiliary components. It may for example comprise a unique identifier such as a numeric or alpha numeric identifier. The identifier may be used to retrieve from a database the configuration of the user interface and/or information to program one or more preparation processes that use the auxiliary component as described above for the respective second and third embodiments. The database may be on the machine (e.g. the memory unit 46) and/or on a remote resource. The database may be accessed using the identifier as a key in a key value database storage paradigm, such as a lookup table. In particular the control system may be operable to determine if the user interface configuration information and/or process information is stored on the machine 4 and if not then to obtain said information from the remote resource. It may also be configured to store the information retrieved from the remote resource locally on the machine. Advantageously it does not have to be obtained from the remote resource again. In a second example the auxiliary component information may comprise information to reconfigure the user interface 36. In particular the user interface information can be received by the control system 16 and processed by the processor 38 to reconfigure the user interface. In a third example the auxiliary component information may comprise information to program the control system (i.e. the memory unit 46 thereof) with one or more preparation processes that use the auxiliary component 52. In particular the process information can be received by the control system 16, processed by the processor 38 and stored on the memory unit 46. The auxiliary component information may comprise combinations of the above first - third examples, e.g. the first example in combination with the second or third example. With such combinations any required information not present in the auxiliary component information can be obtained via database using the identifier, e.g. an identifier in the auxiliary component information that also comprises user interface configuration information can be used to determine process information from a database. Figure 5 is a flow diagram showing an example abstraction of a process of reconfiguring the machine 4 using the auxiliary component information. In particular said information is a combination of the aforedescribed second and third examples and the user interface 36 and memory unit 46 are programmed according to the aforedescribed second and third embodiments.

The control system 16 of the machine 4 may be operable to: determine when an auxiliary component 52 is disconnected from data communication with the communication interface 62; and to disable the user selection via the user interface 36 of the one or more preparation processes that at least partially utilise the auxiliary component. In particular the user interface may be reconfigured back to its original state such that only the main icons 56 are displayed. To determine whether the auxiliary component has been disconnected messages may be periodically sent from the auxiliary component to said machine. If a message is not received within a specified time interval then at timeout the auxiliary component may be determined as disconnected. Alternatively the message may be sent as part of an invocation and response process. The message may comprise the identifier or other alpha numeric code such that the process is not computationally intensive.

The beverage or foodstuff preparation machine 4 may be operable with more than one auxiliary component 52 at a given time, e.g. it can execute processes that use different auxiliary components which are simultaneously operatively connected to the machine 4. It may also be operable to execute preparation processes that utilise more than one auxiliary component as part of a single process.

In particular the control system 16 of the machine 4 may be operable to: receive auxiliary component information from a plurality of auxiliary components; and to enable using the auxiliary component information a user to select via the user interface 36 one or more preparation processes that at least partially utilise each and/or a combination of the auxiliary components. The control system may be operable to reconfigure the user interface to enable a user to select said one or more preparation processes that at least partially utilise each and/or a combination of the auxiliary components. The aforedescribed user interface may be adapted to comprise auxiliary icons that relate to such processes, e.g. in the example shown in figure 4A by adding further auxiliary icons 58 around a first and then second annular ring. In a similar fashion the control system may be programmable to execute the one or more such processes. In providing such functionality the control system 16 can be configured to: when receiving auxiliary component information from an auxiliary component determine if any other auxiliary components are present; and if so then determine if any processes exist which use more than one of the auxiliary components. The latter can be achieved via a database on the machine 4 and/or on the remote resource and/or in the auxiliary component information itself.

Auxiliary Component

The auxiliary component 52 comprises: auxiliary component information stored on a memory unit; a communication interface to transmit said information to the communication interface 62 of the beverage or foodstuff preparation machine 4; and an auxiliary processing unit operable to perform part of a preparation process. Typically the auxiliary component comprises a similar control system to that of the beverage or foodstuff preparation machine, i.e. a processor operatively connected to the aforesaid: memory unit; communication interface; and auxiliary processing unit. It may optionally comprise a user interface, however an advantageous feature of the invention is that a user interface on the auxiliary component can be obviated for cost efficacy. The auxiliary processing unit may comprise at least one selected from a group consisting of: a steaming unit (e.g. a water steamer); a milk processing unit (e.g. a unit that processes milk, such as by heating and/or frothing); an auxiliary product unit (e.g. a unit operable to dispense an auxiliary product such as: sugar; a topping or flavouring that may comprise a syrup, fruit extract, chocolate etc.); a cooling unit (e.g. a unit operable to cool a liquid beverage or foodstuff such as: a heat pump that operates by transfer of thermal energy to cool the beverage or foodstuff; a unit that can supply ice and/or cold water to the beverage or foodstuff); a frothing unit (e.g. a unit operable to froth a beverage in a receptacle). The particular configuration of the auxiliary processing unit is selected for the configuration of the beverage or foodstuff preparation machine 4.

Processes Available Due to Auxiliary Component The auxiliary component 52 provides one or more additional preparation processes for the beverage or foodstuff preparation machine 4. In particular such a preparation process executed by the control system 16 of the machine 4 may comprise providing instructions to an end user via the user interface 36 for end user control of the auxiliary component. As an example of this configuration, wherein the machine 4 is for coffee preparation and the auxiliary component 52 is a milk processing unit, the control system 16 as part of a preparation process for a coffee comprising processed milk (e.g. a latte or cappuccino) may control the component processing unit 14 to: dispense one or more expresso shots into a receptacle; provide instructions on the user interface 36 for end user control of the milk processing unit to process milk and its application into the receptacle, e.g. what settings to use on a user interface of the milk processing unit and when to supply processed milk to the receptacle. In an alternate and preferred configuration the control system 16 controls the auxiliary component 52 via the communication interface 62. Such a configuration is preferred since it is more convenient for the end user. In particular the control system 16 may control the component processing unit 14 and auxiliary component concurrently and/or sequentially. In the instance of sequential operation layers of component from the beverage or foodstuff machine 4 and the auxiliary component may be alternatively dispensed. In the instance or concurrent operation a layer comprising both components may be dispensed. The auxiliary component 52 may communicate over the communication interface 62 to indicate the completion of part of an instructed process, e.g. the completion of the dispensing of an aforesaid layer, or an operation such as frothing of the beverage.

The control system 16 may control one or more further auxiliary components via the communication interface 62. Said control may be concurrent with the component processing unit 14 and/or the aforesaid auxiliary component or sequential. In particular further layers or mixed layers can be dispensed. As a specific example, wherein the machine 4 is for coffee preparation and the auxiliary component 52 is a milk processing unit, the control system 16 as part of a preparation process for a coffee comprising processed milk (e.g. a latte or cappuccino) may control the component processing unit 14 to: dispense one or more espresso shots into a receptacle; control the milk processing unit to process (e.g. by heating and/or frothing) milk and dispense the correct quantity of milk in sequence with the coffee (generally after the coffee) into the receptacle. In particular the control system 16 may control the component processing unit 14 and the auxiliary component 52 to operate sequentially to supply one or more pairs of alternating layers of coffee and processed milk. They may also be controlled to operate at the same time to provide mixed layers adjacent either a coffee or milk layer. The first embodiment may be extended with additional auxiliary components, such as an auxiliary product unit for production of flavoured coffees (e.g. caramel latte) and/or a cooling unit to make cooled coffees (e.g. iced mocha). In such an example the control system 16 may control said auxiliary component to dispense flavouring layers in addition to the aforedescribed coffee and milk layers.

As a further specific example of the first embodiment, wherein the machine 4 is for frozen yoghurt preparation and the auxiliary component 52 is a topping unit, the control system 16 as part of a preparation process may control the component processing unit 14 to: prepare the yoghurt in a receptacle; control the topping unit to supply a topping to the frozen yogurt following its preparation.
