Description

Technical Field

[0001] The present disclosure generally relates to an electrically operated beverage or food preparation system by which a beverage or food is prepared from pre-portioned capsules. Background Art

[0002] A system for preparing a beverage comprises a beverage preparation machine and a capsule. The capsule comprises a single serving of a beverage forming precursor material, for example ground coffee or tea. The beverage preparation machine is arranged to perform a beverage preparation process on the capsule, typically by exposing pressurized, heated water to the precursor material. Processing the capsule in this manner causes the precursor material to be at least partially extracted from the capsule as a beverage.

[0003] This configuration of beverage preparation machines is increasingly popular due to: 1) enhanced user convenience compared to conventional beverage preparation machines (e.g., compared to manually operated stovetop espresso machines), and 2) enhanced beverage preparation processes, wherein: preparation information encoded by a code on a capsule is read by the machine to define a recipe; and the recipe is used by the machine to optimize the preparation process in a capsule-specific manner. Specifically, the encoded preparation information may include operating parameters selected in the beverage preparation process, including: fluid temperature; fluid pressure; preparation duration; and fluid volume.

[0004] The code for such a capsule may encode the value of an operating parameter as the distance of a cell of the code from a reference point, wherein the magnitude of the distance is positively correlated with the magnitude of the value. A digital image of the code is then processed to extract the value.

[0005] The disadvantage is that errors may occur when extracting the value. Such errors may be caused by one or more of the following: 1) printing errors when forming the cells of the code may introduce a certain degree of variability in the value, for example there may be errors in the position of the center point of the cell; 2) if the substrate carrying the code is deformed, for example due to processing, deformation or other non-uniformities of the substrate may also introduce errors in the value extracted from the digital image; 3) processing errors may also introduce a certain degree of error in the extracted value, for example if the code is not aligned when reading so that the plane of the code is not perpendicular to the direction in which the digital image was acquired, and 4) other similar problems.

[0006] Thus, despite the effort that has been put into developing the described systems, further improvements are needed. Summary of the invention

[0007] The present disclosure provides a system comprising a container and a machine for preparing a beverage and / or a food product or a precursor thereof.

[0008] In an embodiment, a container is used to hold a precursor material, the container is used for use with a machine for preparing a beverage and / or food or a precursor thereof, the container comprising a machine-readable code storing preparation information for use with a preparation process performed by the machine. As used herein, reference to a "code" may include one or more repetitions of the code.

[0009] In an embodiment, the container includes a main body portion having a storage portion for accommodating a precursor material and a closure member for closing the storage portion. In an embodiment, the code is arranged on the closure member. In an embodiment, the storage portion includes a cavity extending from the closure member in a depth direction. The container may have a maximum depth less than its diameter, which may be measured at the opening of the storage portion. In an embodiment, the main body portion includes a flange portion connecting the storage portion and the closure member. In an embodiment, the cavity of the storage portion extends from the flange portion in a depth direction. The flange portion may present a peripheral edge of a substantially planar surface for receiving the closure member. In an embodiment, the flange portion is planar. As used herein, the term "planar" with respect to the flange portion may refer to the flange portion being arranged to extend completely in a transverse direction and a longitudinal direction, or extending substantially in said direction (e.g., having a major component in these directions opposite to the depth direction). In an embodiment, the container is alternatively implemented as a pouch. In an embodiment, the container is alternatively implemented as a pouch. In an embodiment, the body portion is formed from walls that are joined and / or folded at seams (eg, for a container arranged as a pouch).

[0010] In an embodiment, a machine for preparing a beverage and / or food or a precursor thereof comprises: a code reading system for reading a code of a container; a processing unit for processing a precursor material of the container; and an electrical circuit system for controlling the processing unit based on preparation information read from the code (including corrected preparation information or uncorrected preparation information or stored corresponding preparation information, as will be discussed). The code reader may include an image capture unit (e.g., a camera), a lens, and an outermost aperture (e.g., a reading window). The outermost portion of the code reader may be referred to as a reading head.

[0011] In an embodiment, the machine includes an electronic memory (which may be implemented by an electrical circuit system) for storing corresponding preparation information based on one or more previous readings of the corresponding code of the container.

[0012] In an embodiment, an electrical circuit system (e.g., of a machine and / or system) is configured to: read preparation information from a code; retrieve corresponding preparation information from an electronic memory; correct the read preparation information based on the corresponding preparation information, and control a processing unit based on the corrected preparation information.

[0013] By implementing the system's processing circuitry to correct the read preparation information using stored preparation information from a comparable code that has previously been read, any errors that may have occurred if the parameters of the preparation information were incorrect in obtaining the parameter values ​​can be reduced, which can improve the accuracy of control of the processing unit for a particular container.

[0014] As used herein, the term "based on one or more previous reads" may refer to stored preparation information obtained in at least one previous step for reading the same code from different containers. Thus, parameter values ​​from previous reads are considered to be the same, but may differ due to reading and processing errors.

[0015] As used herein, the term "correction" with respect to the read preparation information may refer to digitally changing the parameter value read from the code using the value of the corresponding stored preparation information in some manner to improve accuracy. Thus, the corrected preparation information includes a combination of the values ​​of the read preparation information and the stored corresponding preparation information, rather than just one of these.

[0016] As used herein, the term "based on" with respect to the control of the preparation information (in the form of correction or reading, etc.) and the processing unit can generally refer to the value of the parameter set on the control processing unit, such as the temperature, pressure or time of the setting. The value can be directly encoded by a code, such as a coding distance d directly encoding the value. The coding distance d can be related to the value by a rule (e.g., a formula, such as a linear or non-linear relationship). The rule can be stored on an electronic memory, for example, as a lookup table that relates d to the value of the parameter. In this case, the correction of the preparation information as defined herein can refer to the absolute value of the parameter determined as the coding distance d or according to the corrected coding distance d.

[0017] As used herein, the term "controlling a processing unit based on corrected preparation information" may refer to corrected preparation information for controlling a processing unit. It may include a combination of both read preparation information and stored preparation information for controlling a processing unit in some combination.

[0018] In an embodiment, the electrical circuit system is configured to: identify the container, and based on a stored relationship between the identity and the corresponding preparation information obtained from a previous container of the same identity, retrieve the corresponding preparation information from the electronic storage. By implementing the electrical circuit system to identify the container, for example, via shape, color or other characteristics, the identity can be used to accurately look up the stored preparation information.

[0019] In an embodiment, the electrical circuit system is configured to identify the container based on an identifier encoded by the code. By implementing the identifier in the code, the identifier can be determined from a digital image of the same code as the preparation information, and the identifier can be used to accurately find the stored preparation information. By implementing the identifier as a key, a key value database paradigm can be used to find specific stored preparation information.

[0020] In an embodiment, the code comprises: a reference portion for locating the code, and a data portion for storing the preparation information. The identifier may be stored by the data portion.

[0021] In an embodiment, the data portion is arranged at a predetermined position relative to a reference portion (for example, it is stored on an electronic memory), wherein the data portion (including at least a portion) is arranged on a coding line D, and the data unit is arranged along the coding line D at a certain distance d from the starting position as a variable used to at least partially encode the parameter value of the preparation information.

[0022] In an embodiment, the distance (d) may be any continuous distance from the starting position or as a discrete predefined position.In an embodiment, there are multiple encoding lines and the data portion is arranged as one or more separate data portions on each of the multiple encoding lines.

[0023] In an embodiment, the reference portions are arranged to define a linear reference line (L), and the encoding lines are circular and arranged to intersect the reference line (L). By implementing circular encoding lines, the data portions can be compactly arranged, including having varying priorities depending on the radial position of the encoding line on which they are positioned, for example, larger radial positions can have greater encoding accuracy due to greater circumferential distance.

[0024] Using circular coding lines, the geometric distance for encoding the value of the parameter of the prepared information can be: the actual distance, such as the circumferential distance from the starting part to the data unit; the angular distance defined by the angle between the starting position and the data unit; another geometric quantity related to any of the above.

[0025] In an embodiment, the identifier is arranged as one or more discrete positions, and the discrete positions include or do not include a unit for encoding the identifier. The discrete positions may be arranged at predefined positions relative to the reference portion. The predefined positions may be relative to the radial distance from the reference portion and the angle from the reference line. By implementing the identifier as a discrete position, the accuracy of the encoding can be improved to a predefined value associated with the position. In an embodiment, the identifier is encoded as binary information, for example, there is a unit for encoding one of a logical 1 or 0, and there is no unit for encoding the other of a logical 1 or 0. As used herein, the term "binary information" may refer to information encoded as 1 and 0.

[0026] In an embodiment, at least a portion of the identifier is arranged distally of the or each coding line, for example, wherein the or each coding line is arranged between the code identification portion and the reference portion. By arranging the identifier to be separated from the coding line on which the preparation information is arranged, the identifier can be clearly distinguished from the preparation information.

[0027] In an embodiment, at least part of the identifier is arranged on the or each encoding line.By implementing the identifier on an encoding line, the amount of information held by the identifier may be increased.

[0028] In an embodiment, the electrical circuit system is configured to obtain a parameter value from at least two different codes and determine the parameter value as its average value. By determining the parameter value based on more than one code, any errors that may have occurred when obtaining any parameter value from each of the codes can be reduced. The electrical circuit system can be configured to perform this step before correcting the parameter value using the stored preparation information.

[0029] In an embodiment, the preparation information stored by the code includes a parameter value encoded for the parameter; the corresponding preparation information stored by the electronic memory includes a correction value for the parameter value, and the electrical circuit system is configured to correct the parameter value based on the correction value.

[0030] In an embodiment, the correction value comprises an average value derived from a plurality of associated parameter values ​​of the parameter obtained from said previous reading of the corresponding code of the container (e.g., the average value may be determined as the sum of the associated parameter values ​​of the parameter obtained from said previous reading and the read parameter value divided by the total number of values, or may be determined as the sum of the associated parameter values ​​of the parameter obtained from said previous reading divided by their number, which number is combined with the read parameter value).

[0031] In an embodiment, the electrical circuit system is configured to have multiple parameter values ​​for the parameters stored in a stack memory usage mechanism. By implementing a memory architecture with a last-in-first-out manner, such as storing the most recent parameter value as the oldest parameter stored goes out, the memory usage of the electrical circuit system can be optimized in size by avoiding storing an unnecessary number of parameter values.

[0032] In an embodiment, the correction value comprises a weighted sum of previous parameter values. By implementing the correction value to comprise a weighted combination of previous parameter values ​​(eg, as an exponential filter), efficient use of electronic memory may be achieved.

[0033] In an embodiment, the electrical circuit system is configured to update the stored corresponding preparation information based on the read preparation information. By using the last read preparation information to update the stored corresponding preparation information, the stored corresponding preparation information can be frequently updated to ensure that it remains accurate. In addition, for new codes that have not yet been read, the stored corresponding preparation information can be accumulated in the memory.

[0034] In an embodiment, the electrical circuit system is configured to: determine whether the electronic memory includes an entry for corresponding preparation information associated with the code of the container, and if not, control the processing unit based on the read preparation information without using the corresponding preparation information for correction. By implementing the electrical circuit system to determine whether there is any stored corresponding preparation information that can be used to correct the read preparation information, and if then not using the read preparation information without correction, the machine can operate for new codes that have not yet been read.

[0035] In an embodiment, the electrical circuit system is configured to: determine whether the read preparation information is within a threshold of the corresponding preparation information; and if within the threshold, perform the correction of the read preparation information based on the corresponding preparation information. In an embodiment, if the read preparation information is outside the threshold, the electrical circuit system does not perform the correction and / or controls the processing unit based on the corresponding preparation information from the electronic storage.

[0036] By implementing the electrical circuit system to correct only the read preparation information only if the read preparation information is within a threshold of the stored corresponding preparation information, it is ensured that substantial read errors are avoided, which may occur, for example, due to reading the wrong cell or identifying an item as a cell that is not a cell (e.g. debris). In the case of being outside the threshold, updating the stored corresponding preparation information with the read preparation information may be avoided to avoid corruption of the stored corresponding preparation information. In the case of being outside the threshold, the stored corresponding preparation information (and not the read preparation information, as this has not been corrected and stored) may be used to control the processing unit, which may avoid inaccurate control.

The extraction unit 32 includes a capsule holding portion 34 and a closing portion 36. The extraction unit 32 can be moved to a capsule receiving position ( Figure 4 ), in which the capsule receiving position, the capsule holding portion 34 and the closing portion 36 are arranged to receive the capsule 6 therebetween. The extraction unit 32 can be moved to the capsule extraction position ( Figure 5 ), in which capsule extraction position the capsule holding portion 34 and the closing portion 36 form a seal around the capsule 6 and beverage can be extracted from the capsule 6. The extraction unit 32 may be actuator driven or manually movable between said positions.

[0106] The outlet 30 of the fluid conditioning system 22 is arranged as an injection head 38 on the capsule holding part 34 to inject the conditioning fluid into the capsule 6 (usually under high pressure) at the capsule extraction position. The beverage outlet 40 on the closing part 36 is arranged to capture the extracted beverage and convey the extracted beverage from the extraction unit 32.

[0107] The extraction unit 32 is arranged to prepare a beverage by applying a pressurized (e.g., 10 to 20 bar), heated (e.g., 50 to 98 degrees Celsius) fluid to the precursor material within the capsule 6. The pressure increases over a predetermined amount of time until it exceeds the rupture portion of the capsule 6 (at Figure 4 and Figure 5 This causes the portion to rupture and dispense the beverage into the beverage outlet 40.

[0108] In a variant embodiment not shown, although the injection head and the beverage outlet are shown as being arranged on the capsule holding part and the closing part, respectively, they may be arranged alternatively, including: the injection head and the beverage outlet are arranged on the closing part capsule holding part and; or both are arranged on the same part. In addition, the extraction unit may include two parts arranged as the capsule holding part, for example for a capsule symmetrical around a flange, including Professional capsules.

Examples of suitable capsules are Vertuo capsules. A suitable example is provided in EP 2594171 A1. In such an example (or indeed other examples), the guide portion may be omitted and the container manually loaded into the extraction unit.

[0110] In a third example (not illustrated), the capsule processing unit operates by dissolving a beverage precursor selected to dissolve under high pressure and temperature fluid. The extraction unit is arranged similarly to the first and second examples, however, the pressure is lower and therefore a sealed extraction unit is not required. Specifically, the fluid may be injected into the cover of the capsule and the rupture portion is located in the base of the storage portion of the capsule. Examples of suitable capsules are or Dolce Gusto capsules. Examples of suitable extraction units are disclosed in EP 1472156 A1 and in EP 1784344 A1.

[0111] In a fourth example (not illustrated) in which the container is arranged as a sac, the container handling unit implements an extraction unit operable to receive the sac and inject a fluid from the fluid conditioning system at an inlet of the sac. The injected fluid is mixed with a precursor material within the sac to at least partially prepare a beverage, which leaves the sac via an outlet of the sac. Examples of such arrangements are provided in WO2014125123 A1 or in WO2022023578A1.

[0112] In a fifth example (not illustrated), the container processing unit is arranged as a mixing unit to prepare a beverage or food precursor stored in a container, which is a container for consumption from an end user. The mixing unit includes an agitator (e.g., a planetary mixer; a spiral mixer; a vertical cutting mixer) to mix the beverage or food precursor in the container; and a heat exchanger to heat / cool the beverage or food precursor. The fluid supply system can also supply fluid to the container. An example of such an arrangement is provided in WO2014067987A1.

[0116] The bulk material handling unit 42 is arranged to receive bulk pre-precursor material from the container 6 (suitable examples are discussed in detail below). Figure 8 The electrical circuit system 16 uses the preparation information read from the container 6 to control the bulk material processing unit 42 to perform the preparation process.

[0117] The user manually resents the container 6 to the code reading system 18 of the machine 4 to read the code (as will be discussed). The user then opens the container 6 and dispenses the pre-precursor material (not illustrated) disposed therein into the bulk material processing unit 42. The bulk material processing unit 42 processes the bulk pre-precursor material into a precursor material.

[0118] In a specific example, the precursor material is coffee beans, and the bulk material processing unit 42 is arranged to roast and / or grind the coffee beans to provide the precursor material.

The code reading system 18 is integrated with the extraction unit 32 of the first example of the container handling unit 20. The code 44 is read by the extraction unit 32 at the capsule extraction position (e.g. Figure 4 shown).

[0122] The code reading system 18 includes a code reader 46 having an image capture unit and a read head housing the image capture unit for capturing a digital image of the code 44.

In another variant embodiment not illustrated, the code reading system is arranged to read a code at a different position of the container (e.g., on a flange of a restraining portion). In another variant embodiment not illustrated, the code is a one-dimensional code and is read by relative movement between a code reader and the code to generate a code signal.

[0125] [Control electrical circuit system]

[0126] refer to Figure 7 , the electrical circuit system 16 is implemented to control the electrical circuit system 48 to control the processing unit 14 to perform the preparation process. Figure 7In the embodiment of the present invention, for illustrative purposes, the processing unit 14 is illustrated as a first example, and the processing unit includes a container processing unit 20 and a fluid supply unit 22.

[0127] The electrical circuit systems 16, 48 at least partially implement (e.g., in combination with hardware): an input unit 50 for receiving input from a user confirming that the machine 4 will perform a preparation process; a processor 52 for receiving input from the input unit 50 and providing a control output to the processing unit 14; and a feedback system 54 for providing feedback from the processing unit 54 during the preparation process, which feedback can be used to control the preparation process.

[0128] The input unit 50 is implemented as a user interface, which may include one or more of the following: buttons, such as joystick buttons or push buttons; joystick; LEDs; graphic or character LDCs; graphic screens with touch sensing and / or screen edge buttons; other similar devices; sensors for determining whether a container has been supplied to the machine by a user.

[0129] The feedback system 54 may implement one or more of the following or other feedback control-based operations:

[0130] A flow sensor is used to determine the outlet 30 (at Figure 3 2 ), which can be used to meter the correct amount of fluid into the container 6 and thus regulate the power to the pump 26;

[0131] a temperature sensor to determine the temperature of the fluid to the outlet 30 of the fluid supply unit 22, which temperature sensor may be used to ensure that the temperature of the fluid to the container 6 is correct and to regulate the power to the heat exchanger 28 accordingly);

[0132] a level sensor to determine whether the level of fluid in the reservoir 24 is sufficient for the preparation process;

[0133] A position sensor, the position sensor is used to determine the position of the extraction unit 32 (eg, a capsule extraction position or a capsule receiving position).

[0134] It will be appreciated that the electrical circuit system 16, 44 is suitably adapted to other examples of the processing unit 14, such as for the second example of a container processing system, where the feedback system may be used to control the rotational speed of the capsule.

[0135] [container]

[0136] refer to Figure 8A first example of a container 6 for use with a first example of a processing unit 14 includes a container 6 arranged as a capsule 6. The capsule 6 includes a closure member 56 and a body portion 62 including a storage portion 58 and a flange portion 60.

[0137] The storage portion 58 includes a cavity (not shown) for storing the precursor material. The cavity of the storage portion extends from the flange portion 60 in the depth direction 106. Figure 4 and Figure 5 , the storage portion 56 is perforated by the injection head 38 to supply the conditioned fluid into the capsule.

[0138] The storage portion 58 is formed of a paper material. The storage portion 58 has a thickness of 0.2 mm. The closing member 56 is formed of a paper material. The closing member 58 has a thickness of 0.15 mm.

[0139] As used herein, "paper" may refer to a sheet material formed at least in part from a sheet material produced by mechanically or chemically treating cellulose fibers derived from one or more of: wood; rags; grass; or other plant sources in water; draining the water through a fine mesh, leaving the fibers evenly distributed on the surface; followed by pressing and drying.

[0140] The closing member 56 closes and can hermetically seal the storage portion 58, and includes a flexible film. Figure 4 and Figure 5 , the closing member 56 is perforated to eject the beverage / food.

[0141] The flange portion 60 is formed integrally with the storage portion. The flange portion 60 is disposed at the junction of the storage portion 58 and the closure member 56 and comprises a planar extension of the storage portion 58 that overlaps a portion of the closure member secured thereto to hermetically seal the precursor material. The flange portion 60 extends in a plane defined by the transverse direction 102 and the longitudinal direction 100. Thus, the closure member is planar in said plane.

[0142] The capsule 6 is of circular cross-section so that it is rotationally symmetrical about the axis 108. In this way, the user can present the capsule to the machine 2 in any orientation about the axis 108. The capsule 6 has a diameter of 53 mm, which is measured across the outer periphery or inner periphery of the flange portion 60 in the plane of the flange portion 60. The capsule 6 can be configured to have different sizes, which are characterized by different depths, for example: 7 mm; 12 mm; 15 mm; 18 mm; and 21 mm. Each size of the capsule 6 is compatible with the first example and the second example of the code reading system 18, as will be discussed.

[0143] In a variant embodiment not illustrated, the closing member may be arranged to be convex or concave relative to the storage portion. For example, for a convex arrangement, the center of the closing member may extend into the storage portion by up to 1 mm ± 10% or 20% in the depth direction. The minimum depression may be 0.2 mm. For example, for a concave arrangement, the center of the closing member may extend away from the storage portion by up to 4 mm ± 10% or 20% in the reverse depth direction. The minimum depression may be 0.5 mm.

[0144] In non-illustrated variant embodiments: the main body portion includes a flange portion that is not integrally formed with the storage portion and connected to the storage portion; the main body portion includes an omitted flange portion, for example, the closing member is wrapped around the storage portion; the container can be a non-rotationally symmetrical shape, such as a square cross-section or other shape; the capsule is alternatively sized to include an outer circumference or inner circumference across the flange portion of 40mm to 70mm or 53mm±10% or 20%, and a depth of any of the described depths±10% or 20%; the thickness of the storage portion may have a thickness of 0.1mm to 0.4mm or 0.2±20% or 30%; the thickness of the closing member may have a thickness of 0.05mm to 0.3mm or 0.15±20% or 30%; and the storage portion and / or the closing member may be made of or include different materials, for example, including plastic or aluminum-based materials.

[0145] refer to Fig. 9 A second example of a container 6 for use with a second example of a processing unit 14 includes a container 6 arranged as a pouch and includes: an arrangement of sheet material 62 joined at a peripheral seam 64 to define an internal volume for storing a precursor material (not illustrated), and an opening 66 that a user opens to dispense the precursor material into a loose material processing unit 42.

[0146] [Code layout]

[0147] refer to Figure 8 The code 44 may be arranged on the outer surface of the container 6 at any suitable location such that the code can be read by the code reading system 18 .

[0148] In a first example, the code 44 is arranged at a central area of ​​the closure member 56. Thus, the code can be read by any code reader aligned with the center of the container. In a second example, the code is replicated throughout the closure member so that it can be read from any external location on the closure member 56. With such an arrangement, the closure member does not require any specific alignment with the storage portion, which simplifies the cutting and assembly process of the container 6.

[0149] In a variant embodiment not illustrated, the code may be arranged on the flange portion 60 (including on either side) and on the storage portion 58. The code may also be arranged on the closing member, but not on the intermediate area.

[0150] exist Fig. 9 In the second example shown, the code 44 is disposed at various locations on the sheet of material 62 , including distally of the seam 64 .

[0151] [Preparation process]

[0153] Box 70 : The user supplies the container 6 to the machine 4 .

[0154] Box 72: The electrical circuit system 16 (eg, the input unit 50 thereof) receives a user instruction to prepare a beverage / foodstuff from a precursor, and the electrical circuit system 16 (eg, the processor 52) initiates the process.

[0158] Box 80: The electrical circuit system 16 executes the preparation process based on the preparation information by controlling the processing unit 14. In the first example of a processing unit, this includes controlling the fluid conditioning system 22 to supply fluid to the container processing unit 20 at the temperature, pressure and duration specified in the preparation information.

[0159] The electrical circuit system 16 then controls the container handling unit 20 to move from the capsule extraction portion through the capsule ejection position to eject the container 6 and back to the capsule receiving position.

[0160] In alternative embodiments not shown: the above-mentioned frames may be executed in a different order, for example, frame 72 may be executed before frame 70 or frame 76 may be executed before frame 74; a frame may be omitted, for example, frame 70 may be omitted when the machine stores capsule boxes.

[0161] Box 76 and box 78 may refer to code reading and processing. Box 80 may be referred to as a preparation process. Electrical circuit system 16 includes instructions for the preparation process (or multiple preparation processes), for example as program code. In an embodiment, processor 52 implements instructions stored on a memory (not shown).

[0162] As part of the preparation process, electrical circuit system 16 may obtain additional preparation information from server system 8 and / or peripheral device 10 via computer network 12 using a communication interface (not illustrated) of the machine.

[0163] [General description of code]

[0164] refer to Fig.11 , the code 44 is formed of a plurality of circular cells 80 arranged on a surround 82. The cells 80 are dark (e.g., one of the following colors: black, dark blue, purple, dark green), and the surround 82 is a relatively light color (e.g., one of the following colors: white, light blue, yellow, light green), so that the contrast is sufficient for the image capture unit 46 to distinguish them. The cells 80 of the code can be configured to be read in the infrared and / or visible bands.

[0165] The shape of the cell 80 is circular. As used herein, the term "shape" with respect to a cell may refer to an exact shape or an approximation of the actual shape, which may occur due to printing or other manufacturing precision variations.

[0166] In variant embodiments not illustrated: the unit is light-colored, while the surround is dark-colored; the unit has different shapes, including one or a combination of the following shapes: triangle, polygon, in particular quadrilateral such as square or parallelogram; other suitable shapes.

[0167] The cell 80 typically has a cell length of 50 μm to 200 μm. As used herein, the term "cell length" for the cell 80 may refer to a suitably defined distance of the cell 80, such as: for a circular shape, the diameter; for a square, the side length; for a polygon, the distance between opposite or adjacent vertices; for a triangle, the hypotenuse. The cell 80 is cut with an accuracy of about 1 μm.

[0168] The unit 80 is formed by printing (e.g., by means of an inkjet printer). As an example of printing, the ink may be a conventional printer ink, and the substrate may be: polyethylene terephthalate (PET); aluminum coated with lacquer (as present on Nespresso Classic capsules) or other suitable substrates.

[0169] In variant embodiments not illustrated: the cells are alternatively formed, including by embossing, imprinting or other suitable means, and are alternatively dimensioned, for example, to a cell length of 80 μm to 120 μm.

[0170] Further references Fig.11 , the unit 80 is organized into: a reference part R, which is used to locate and determine the orientation of the code 44; and a data part D, which is used to store preparation information.

[0171] The cells 80 of the code 44 arranged as the reference portion R include three reference cells 84. The reference cells 84 have a unique spatial arrangement in the code 44 to allow the reference portion R to be recognized by the electrical circuit system 16 in the digital image (e.g., having a stored relationship on its memory). The unique spatial arrangement includes the reference cells 84 arranged at three of the vertices of the virtual rectangle around the origin O at the center of the rectangle, with specific distances between the reference cells 84.

[0172] In alternative embodiments not illustrated, the reference portion is alternatively implemented to include: different arrangements of reference cells, such as rectangles that are circles or other shapes; different numbers of reference cells, such as 4 or 5; and the reference cells may have a unique shape that can be identified from the shapes of other cells that form the code.

[0173] The arrangement of the reference cells 84 enables a single reference line r to be defined at a particular vector relative to the cells 84. The reference line r is virtual and is determined by the electrical circuit system 16 (eg, having a stored relationship on its memory).

[0174] In this particular example, the reference cells 84 define a first imaginary line (not illustrated) and a second imaginary line (not illustrated) using the right-hand rule, where: the thumb represents the first imaginary line intersecting the centers of two of the reference cells 84; the index finger represents the second imaginary line intersecting the centers of two of the reference cells, one of which is common to the first imaginary line; and the second finger enters the plane of the page of the code 44. The reference line r extends from the origin O and is parallel to the first imaginary line and orthogonal to the second imaginary line.

[0175] In variant embodiments not illustrated, the reference line may be alternatively defined: the reference line may comprise an actual line drawn on the code; the reference line may have an alternative geometrical arrangement relative to the reference cell.

[0176] The unit 80 of the code 44 arranged as the data portion D includes a data unit 86. The data unit 86 is arranged on the encoding line E intersecting with the reference line r. The encoding line E is virtual and is determined by the electrical circuit system 16, (for example, the encoding line has a predetermined radius stored on its memory). The center of the circle of the encoding line E is arranged at the origin O of the reference portion R. Therefore, the reference line r intersects the encoding line E, and the tangent of the encoding line is orthogonal to the reference line r. There are two encoding lines E1, E2, each of which has a data unit 86.

[0177] In variant embodiments not illustrated: other numbers of encoding lines are implemented, including 3, 4 or 5; the encoding lines may have non-circular shapes, including rectangular or triangular; the encoding lines comprise actual lines drawn on the code.

[0178] The encoding line E includes one or more individual data portions, each of which includes a starting position 88 and a data unit 86, which is arranged along the encoding line E at a certain distance d from the starting position 88 as a variable for encoding the parameters of the preparation information. The starting position 88 is virtually defined and can be determined by the electrical circuit system 16 (for example, the starting position can be stored in its memory). The individual data portion may also include an end position (not illustrated), which defines the maximum allowable distance d of the data unit 80 from the starting position 88 along the encoding line E. Both the starting position and the end position are virtually formed.

[0179] For the first encoding line E1, the data portion includes two separate data portions: for the first separate data portion, the distance d can be any continuous distance from the starting position 88 at the reference line r to the first data unit 86 clockwise from the reference line r; for the second separate data portion, the distance d can be any continuous distance from the starting position 88 at the data unit 86 of the first separate data portion (therefore, the starting position is a variable) to the midpoint m between the subsequent two data units 86 in the clockwise direction.

[0180] For the second encoding line E2, the data portion includes a single data portion for which the distance d can be any one of a plurality of discrete distances, which are illustrated as discrete positions 90 from the starting position 88 at the reference line r, each position being associated with a value of a parameter. In the example, there are 10 discrete positions 90.

[0181] The incremental distance may be defined as the distance between the starting position 88 and the ending position divided by the total number of positions in the data portion D that a data unit 86 may occupy (which is 10 for E2).

[0182] In variant embodiments not illustrated: the starting position may be arranged at any position on the coding line, including being spaced apart from a reference line; there may be multiple starting positions on the coding line, each starting position having an associated data unit; the starting position may be formed as a unit as part of the code rather than being virtually defined; the coding line may include a combination of parameters encoded by continuous distances and discrete positions; more than one or two data units on the coding line may define a parameter, which may be determined as an average of the positions; and the data portion may include any appropriate number of separate data portions.

[0183] The code 44 includes an outer perimeter 92 within which the cells 80 are arranged. The outer perimeter 92 is rectangular in shape and has a size of 600 μm to 1600 μm, or about 1100 μm. The code 44 may be repeated so that multiple repetitions of the code 44 are arranged within a single digital image so that one or several best captured repetitions of the code may be selected for processing.

[0184] In non-illustrated variant embodiments: the outer periphery can be alternatively shaped, including circular; the outer periphery can have alternative sizes, including larger or smaller than the exemplary range. In non-illustrated variant embodiments, the data portion alternatively encodes the value of the parameter, including as alphanumeric symbols or other arrangements.

[0185] refer to Fig.12 , relative to Fig.11 The code processing process for extracting the preparation information performed by the electrical circuit system 16 (or its code processing circuit system) includes:

[0186] Step 1 - Identify the location of the code unit

[0187] Box 100 : A digital image of the code 44 is obtained via the code reading system 118 .

[0188] Block 102 : Allocate pixels to dark areas in the digital image that may represent the cell 80 .

[0189] Box 104: If several pixels are grouped close to each other, it is determined that cell 80 exists.

[0190] Block 106: For each determined cell, determine the center of the pixel grouping by, for example, a feature extraction rule to determine the coordinates of the center of the cell.

[0191] In unmodified embodiments not illustrated, alternative processing techniques for determining cells and coordinates may be implemented, including other techniques for locating the center of a cell or identifying a cell as present, for example, a magnification level may be implemented such that a single pixel is determined to be a cell, and the center of a cell may be determined as the center of a pixel.

[0192] Step 2 - Locate the reference part of the code and the reading angle

[0193] refer to Fig.13 , relative to Fig.11 The code for code 44 includes:

[0194] Block 108: Locate reference portion R by searching the coordinates of cells 80 of code 44 to identify a unique separation and geometric arrangement of reference cells 84. This may be accomplished by geometric rules including Pythagoras and trigonometry or other suitable rules. The separation and geometric arrangement may be stored on electrical circuit system 16 and accessed during the search.

[0195] Block 110: Using stored relationships to define the positions of origin O and reference line r for the located reference portion R. The arrangement of origin and reference line may be stored on the electrical circuitry 16 and mapped to the coordinates of the located reference portion.

[0196] Block 112: For each cell (except cells of the reference portion), determine which encoding line E the cell belongs to based on the distance from the origin O. The electrical circuit system 16 may store a radius range for each encoding line E and use geometric rules to determine the distance of each cell from the origin O and within which radius range it falls.

[0197] Box 114: For each cell (except the cells of the reference part), determine the angle α1, α2 relative to the reference line r. It should be noted that this angle represents the circumferential distance and can be used interchangeably. The angle can be calculated via the known geometric relationship between the coordinates of the reference line r and the virtual line extending from the origin O and passing through the associated cell.

[0198] Step 3 - Determine the values ​​of the parameters of the preparation information.

[0199] refer to Fig.13 , relative to Fig.11 The code for code 44 includes:

[0200] Block 116: Determine the encoding distance d for each individual data portion. This is accomplished by a set of rules for determining the encoding distance d stored by the electrical circuit system 16. This may include one or more of the following: the number of individual data portions on each encoding line; the starting position 88 of each data portion; whether a single cell or multiple cells represent a data unit 86; and other suitable relationships.

[0201] For example, refer to Fig. 9, the rule for determining the encoding distance d of the encoding line E1 includes: two separate data parts; the starting position 88 of the first separate data part is at the intersection between the reference line r and the encoding line E1; the starting position 88 of the second separate data part is at the data unit 86 of the first separate data part; the data unit 86 of the first separate data part is represented as a single unit of the code 44; the data unit 86 of the second separate data part is represented as two units of the code 44.

[0202] For example, refer to Fig.11 , the rules for determining the encoding distance d of the encoding line E2 include: a single individual data portion; the starting position 88 is at the intersection between the reference line r and the encoding line E2; the data unit 86 of the first individual data portion is represented as a single unit of the code 44.

[0203] Box 118 : Convert the encoded distance d for each data portion into a value of the parameter This is achieved by implementing a set of rules for converting distances of values ​​stored by the electrical circuit system 16 .

[0204] For example, for the encoded line E1: the first separate data portion can encode the water volume of the brewing process, where the distance d is any continuous value linearly related to the water volume; and the second separate data portion can encode the time of the brewing process, where the encoded distance d is any continuous value related to the time index.

[0205] For example, for encoding line E2: a single separate data portion may encode the water temperature of the brewing process, where the encoding distance d is a discrete value that changes incrementally by 5 degrees Celsius for each discrete position 90, and the rule specifies which 5 degree increment is closest to the determined encoding distance d.

[0206] In variant embodiments not illustrated, other rules may be implemented, including: other mathematical functions relating the encoding distance to the parameter value; whether the encoding distance is the average of the distances of several separate data portions, and other suitable relationships, and the distance d may directly encode the value, so that no conversion is required.

[0207] [Parameter value correction]

[0208] refer to Fig.14 The electrical circuit system 16 implements an electronic memory (not shown) for storing corresponding preparation information based on one or more previous readings of the corresponding code of the container. Fig.14 The previous read is obtained by a previous execution of the associated process, as will be discussed below.

[0209] The electrical circuit system 16 implements the following steps:

[0210] Block 120: Read the preparation information from the code 44. This block implements the Fig.12 The blocks 100 to 106 shown and Fig.13 The process discussed at blocks 108 to 118 is shown wherein a value of at least one parameter of the preparation information is obtained from a digital image of the code.

[0211] Block 122: Retrieve corresponding preparation information from electronic memory. This block consists in retrieving values ​​of parameters (or aggregate values ​​derived therefrom) corresponding to those obtained from block 120. These values ​​are corresponding because they were previously obtained from reading one or more identical codes and stored on the electronic memory, for example from a container previously processed by the machine 2.

[0212] Block 124: Correcting the read preparation information based on the corresponding preparation information This block includes retrieving the corresponding preparation information from block 122 for increasing the accuracy of the values ​​of one or more parameters obtained from block 120, an example of which will be provided.

[0213] Block 126: Controlling the processing unit 20 based on the corrected preparation information, and Fig.10 An example of this is shown previously discussed with respect to block 80 .

[0214] [Box 120—Read Preparation Information]

[0215] Considering the above blocks in more detail, block 120 is implemented for parameters having values ​​encoded as any continuous distance d from a starting position. As such, reading accuracy is important and is particularly addressed by the correction step of block 124 as will be discussed.

[0216] Although, for convenience, the subsequent detailed examples generally refer to a single value of a parameter encoded by code 44 being corrected, it should be understood that all or some of the values ​​of the parameter encoded by code 44 may be corrected by the same process.

[0217] In a variant embodiment: the parameter has a value that is alternatively encoded as a discrete predefined position from a starting position, such alternative encoding can also be corrected according to the steps disclosed herein; and in a specific variant, the electrical circuit system is configured to obtain at least two equivalent parameter values ​​from at least two different repetitions of the same code, and determine the parameter value as its average value, which is subsequently corrected by the process discussed.

[0218] In variant embodiments, the process may be implemented for alternative codes, including QR or bar codes.More generally, preparation information may also be corrected according to the process in question, including values ​​of parameters other than the correctable identifier.

[0219] [Block 122—Retrieve Preparation Information from Memory]

[0220] At box 122, the code 44 encodes an identifier that is read when the code 44 is processed. The electronic memory includes a stored relationship (e.g., as a key value database example) between the identifier and the value of the parameter of the corresponding preparation information obtained from a previous reading of the code of a container of the same identity (or an aggregate value derived therefrom, including a previously corrected value).

[0221] The identifier is located at a predefined position relative to the reference portion R. The predefined position is stored on an electronic memory so that once the reference portion R has been located and its orientation has been identified (e.g. for Fig.13 The identifier may be read as discussed in blocks 108 and 110 of FIG. 1. Thus, it may not be necessary to fully read the data portion D to determine the identifier.

[0222] In the first example, the identifier is represented by Fig.11 The previously discussed discrete positions 90 of the encoding line E2 of the associated data portion D are encoded. The discrete positions 90 may or may not contain a unit for encoding the identifier. Although the discrete positions 90 are shown on the encoding line E2, in a variant embodiment not illustrated, they may be arranged on any one or more of the encoding lines.

[0223] In the second example, reference Fig.15 , the identifier is encoded as a discrete position 94, which is distal to the or each encoding line E1, E2.

[0224] In a third example, the first and second examples are combined such that the identifier is segmented at discrete locations 90 , 94 .

[0225] In variant embodiments of the first or third examples, the discrete position 90 may follow the data unit 86 (eg at a predefined position on the encoding line E2 ) so that the identifier is encoded on the same line as the parameters of the data portion D.

[0226] In alternative embodiments not illustrated, the code or container is alternatively identified for retrieving corresponding preparation information (rather than by using a coded identifier), including by one or more of: shape; color; material, and other characteristics (each of which may be determined by a suitable sensor, such as a camera or inductive sensor, etc.).

[0227] refer to Fig.16, the electrical circuit system 16 after block 122 at block 130 is configured to determine whether the electronic memory includes an entry for the corresponding preparation information for the identifier. If not, the previously discussed block 124 is omitted and block 126 is executed. However, at block 126, the processing unit 20 is alternatively controlled based on the preparation information read from the code without making corrections using the corresponding preparation information. Such a situation may occur when a new type of container 6 is used for the first time.

[0228] Furthermore, block 132 is executed, in which the read preparation information is stored as corresponding preparation information. Thus, if the same capsule type is used again, an entry for the corresponding preparation information exists, and block 124 is alternatively executed.

[0229] [Box 124 - Correction Preparation Information]

[0230] At block 124, the value of the parameter of the read preparation information is corrected to improve accuracy. The correction uses the value of the retrieved corresponding preparation information (or a quantity derived therefrom) as a correction value.

[0231] In the first example, the value of each previously read parameter for the code 44 is stored as the corresponding preparation information. The value in the currently read preparation information is then added to the value and averaged. This average value (e.g., mean value) is then used as the value in the corrected preparation information to control the processing unit 20. Thus, in the first example, the value of each previously read parameter for the code 44 includes the corrected value.

[0232] To control memory usage, a stack memory usage mechanism is implemented that replaces the oldest of the stored values ​​with the newest value once the stack is filled in a last-in-first-out manner. Thus, a predetermined amount of values, such as 5 or 10, can be stored. The stack memory usage mechanism may be useful if the manufacturer chooses to make small changes to the values ​​over time, as the older values ​​will be removed and have less impact on the calculation.

[0233] In variant embodiments, other corrections are applied, such as taking the median instead of the average; other memory usage mechanisms are implemented.

[0234] In a second example, a weighted sum of previous parameter values ​​is stored as corresponding preparation information on an electronic memory. In one example, an exponential filter is implemented. Such an example may not be as intensive in terms of memory storage as the first example.

[0235] With an exponential filter, a weighted combination of previous values ​​can be stored and combined with the newly read value, where the sum of the weights α equals 1, for example:

[0236] Correction value = α. Newly read value + (1-α). Previously corrected value from corresponding preparation information. Thus, in the second example, the sum and weight of the values ​​of each previously read parameter for the code 44 comprises the correction value.

[0237] As part of block 124 , the electrical circuit system 16 updates the stored corresponding preparation information.

[0238] For the first example, this includes saving the read value of the parameter to memory, for example using a stack memory mechanism, the new value replacing the oldest value of the entire stack.

[0239] For the second example, this includes setting the previously corrected value from the corresponding preparation information equal to the corrected value.

[0240] In the above examples, reference has been made to the value being corrected. However, this step is intended to refer to any step of the value determination process as previously described. For example, the correction of the value includes correcting the encoded distance d before converting it to the absolute value of the parameter. In such examples, d is considered to be the read value of the parameter, and the corresponding value stored is the stored value of d from the previous reading. That is, the process should not be understood as being limited to operating on the absolute final value of the parameter.

[0241] [Handling exceptions]

[0242] refer to Fig.17 As part of block 124, at block 134, for the read value, the electrical circuit system 16 determines whether a threshold has been exceeded. This includes comparing the read value to the value of the corresponding preparation information (including: for the first example, comparing the average of these values; for the second example, comparing the previously corrected value or making other suitable comparisons based on the values). For example, the threshold may be set to ±10 or ±20 of the previously corrected value or average value from the corresponding preparation information.

[0243] If the threshold is exceeded, it may be assumed that a read error has occurred in the distance d (e.g., because an erroneous cell was identified or a fragment was identified as the cell or other similar situation). In this case, block 136 is executed, which includes removing the read value (without the previously described update of the corresponding stored preparation information). The processing unit 20 is then controlled using the corresponding stored preparation information, which is retrieved by the identifier (or other identification method).

[0244] If the threshold is not exceeded, then block 124 is performed as previously described, including correction at block 138 and updating of stored corresponding preparation information at block 140 .

[0245] In a variant embodiment, block 134 is omitted and no comparison to the threshold is made.

[0246] Although the or each code is illustrated herein as being arranged on a container, it will be appreciated that the code may be formed integrally on the container or on a separate substrate (not illustrated) which may be attached to the container, or; attached to a machine, for example as a tab for arrangement between the container and a code reader so that an existing code reading arrangement may be used, or; other components, for example a handheld component including a code reader arranged for presentation to the machine by a user, which code reader may be appropriately arranged for manual code reading.
