the reference portion comprising an arrangement of at least two reference units defining a reference line;
the data portion comprising:
a plurality of sectors arranged on an encoding line, whereby each sector is bounded by a first circumferential position and a second circumferential position on the encoding line and each sector comprises a data unit arranged on the encoding line between the first and second circumferential position, the data unit arranged a distance from the first circumferential position along the encoding line as a variable to at least partially encode a parameter of the preparation information, whereby the encoding line is circular and is arranged with a tangent thereto orthogonal the reference line at an intersection point.
2. The container of claim 1 , wherein the distance entirely encodes a value of a parameter of the preparation information, the parameter selected from the group consisting of: fluid temperature; preparation duration; mixing conditions; fluid volume; fluid flow rate; torque; angular velocity; pressure; % cooling power; time; expiry date; container geometric properties; phase identifier; container identifier; recipe identifier; pre-wetting volume; phase duration; container identifier; compartment identifier; and container geometric parameters.
3. The container of claim 1 , wherein the data units are arranged at any continuous distance between the associated circumferential positions.
4. The container of claim 1 , wherein the code comprises a plurality of concentric encoding lines, the encoding lines each having the same number of sectors, whereby corresponding sectors encode a distinct phase of a preparation process.
5. The container of claim 1 , wherein the code has a peripheral length of 600-1600 μm.
6. The container of claim 1 , wherein the code is formed on a surface of the container or on an attachment, which is attached thereto.
7. The container of claim 1 , wherein the container is in a form selected from the group consisting of: a capsule; a packet; a receptacle for end user consumption of the beverage or foodstuff therefrom; and a collapsible container.
8. A beverage or foodstuff preparation system comprising: a code encoding preparation information, the code comprising a reference portion and a data portion, the reference portion comprising an arrangement of at least two reference units defining a reference line, the data portion comprising: a plurality of sectors arranged on an encoding line, whereby each sector is bounded by a first circumferential position and a second circumferential position on the encoding line and each sector comprises a data unit arranged on the encoding line between the first and second circumferential position, the data unit arranged a distance from the first circumferential position along the encoding line as a variable to at least partially encode a parameter of the preparation information, whereby the encoding line is circular and is arranged with a tangent thereto orthogonal the reference line at an intersection point; and a beverage or foodstuff preparation machine, the preparation machine comprising:
a container processing subsystem to receive the container and to prepare a beverage or foodstuff therefrom;
a code processing subsystem operable to: obtain a digital image of the code of the container; process the digital image to decode the encoded preparation information; and
a control subsystem operable to control the container processing subsystem using the decoded preparation information.
9. A method of encoding preparation information, the method comprising forming a code on:
a container for a beverage or foodstuff preparation machine, the container for containing beverage or foodstuff material; or
an attachment for attachment to said container or a beverage of foodstuff preparation machine,
the method further comprising:
arranging at least two reference units to define a reference line of a reference portion; and
at least partially encoding a parameter of the preparation information with a data portion of the code by arranging a plurality of sectors on an encoding line, whereby each sector is bounded by a first circumferential position and a second circumferential position on the encoding line and each sector comprises a data unit arranged on the encoding line between the first and second circumferential position, the data unit arranged a distance from the first circumferential position along the encoding line as a variable to at least partially encode a parameter of the preparation information, whereby the encoding line is circular and is arranged with a tangent thereto orthogonal the reference line at an intersection point.
