A container for a foodstuff or beverage preparation machine, the container for containing beverage or foodstuff material and 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 r, the data portion comprising: a plurality of adjacent sectors arranged on an encoding line D, whereby each sector is bounded by a first circumferential position and a second circumferential position on the encoding line D and each sector comprises a data unit arranged on the encoding line D between said first and second circumferential position, the data unit arranged a distance d extending from the first circumferential position as a variable to at least partially encode a parameter of the preparation information, whereby the encoding line D is circular and is arranged with a tangent thereto orthogonal the reference line r at an intersection point.

Disclosed are various embodiments of a multi-scale fiducial. A multi-scale fiducial may have three or more scales, where the child fiducials are nested or otherwise linked by a relative position to the parent fiducials. Multi-scale fiducials may facilitate target identification and tracking at varying distances, potentially without the aid of a scale-invariant recognition algorithm. One application of multi-scale fiducials may involve target identification for autonomously controlled aerial vehicles.

A code support for association with or part of a capsule used in delivering a beverage in a beverage producing device by centrifugation of the capsule is disclosed. A capsule that includes the code support, as well as a system to read and process the code support, are also disclosed. Further disclosed is a method of reading and processing the code support.

The inventive apparatus for printing, sending, receiving and counting absentee ballots, comprises a printer for creating a plurality of ballots, each of the ballots bearing a unique code device containing a unique identification code and a would-be voter personal computing device for sending a communication from a would be voter requesting a ballot and for sending personal identification information. The personal computing device must receive a biometric to become activated. A board of elections computing device receives a communication from a would-be voter requesting a ballot, the board of elections computing device being operated by software which causes it to execute a number of program steps comprising verifying that the personal computing device must receive a biometric to become activated, receiving personal identification information from the would-be voter personal computing device, and comparing the received personal identification information with voter record information contained in the database of registered voter information a board of elections to determine whether the would-be voter is registered to vote. A balloted voter database is adapted for storing a notation of a positive identification of the would-be voter as a registered voter, and for storing in the balloted voter database a notation that the would be voter is to be sent one of the ballots. A scanning device is adapted for scanning the unique code device on one of the ballots. A sent ballots database stores the identification of the one ballot in the sent ballots database. A voted ballots database receives an indication that a communication has been received from the registered voter personal computing device of the would be voter, the communication comprising the output of a scan of the unique code device on the ballot sent to the would-be voter, the information including the unique identification code, whereby returned voted ballots may be assessed for authenticity, wherein the program of steps comprises assessing authenticity of return ballots by determining that each ballot is included in the sent ballots database and is included in the voted ballots database, whereby the ballots that are included in the sent ballots database and in the voted ballots database are identified as verified ballots, and the election choices in the verified ballots may be counted.

A method for authenticating an article including engraving a circular feature into a verification substrate that includes a plurality of concentric rings within the circular feature arranged in a pattern according to a data encoding schema, wherein at least one of the plurality of rings includes a surface anomaly. The method can include capturing a first image of the circular feature and storing the first image in a memory device. The verification substrate can be attached to an article to traced and/or authenticated. A second image of the circular feature can be captured and compared with the first image to determine if the surface anomaly is present in the second image, thereby authenticating the article.

A generation method for a barcode is disclosed. The generation method for a barcode includes: obtaining a dotted line segment based on a barcode generated in a reference encoding mode and an intersection between the barcode and a straight line perpendicular to a black stripe in the barcode; and rotating the dotted line segment by 180 degrees by using either one of two endpoints of the dotted line segment as a center of a circle, to generate a semicircular barcode.
