Encoding method for encoding medical items
First Claim
1. A method for generating at least one coding on an item, wherein the coding comprises at least one information component in encoded form, wherein the method comprises the following steps:
- a) converting the at least one information component into a code, wherein the code comprises a plurality of value pairs each pair comprising a gray-scale value and a degree of filling;
b) converting the code into an optical information component, wherein the optical information component comprises at least one field filled with at least one gray-scale value up to an associated degree of filling in accordance with the code; and
c) applying the optical information component to the item.

Abstract
A coding for a medical disposable item is proposed comprising at least one information component in encoded form. Associated encoding methods and devices, and associated decoding methods and devices, are also proposed. The coding generally comprises an optical information component comprising one or more fields filled with a gray-scale value up to a certain degree of filling. Each gray-scale value and degree of filling are associated as a value pair determined as part of a code generated to correlate to an information component desired to be applied to and conveyed from a medical disposable item to an associated device that utilizes such items.
