La technologie du code à barres est basée sur la reconnaissance de motifs constitués de barres et d'espaces présentant des dimensions définies. Il existe diverses méthodes pour coder des informations sous la forme d'un code à barres, connues sous le nom de symbologie et les règles définissant la traduction des caractères en motifs de barres et d'espaces et en d'autres…

ISO/IEC 24728:2006 specifies the requirements for the bar code symbology known as MicroPDF417. It specifies the MicroPDF417 symbology characteristics, data character encodation, symbol formats, dimensions, error correction rules, decoding algorithm, and a number of application parameters. MicroPDF417 is a multi-row symbology, derived from and closely based on PDF417. MicroPDF417 is designed for…

The technology of bar coding is based on the recognition of patterns of bars and spaces of defined dimensions. There are various methods of encoding information in bar code form, known as symbologies, and the rules defining the translation of characters into bars and space patterns and other essential features are known as the symbology specification. ISO/IEC 15438:2006 specifies the requirements…

ISO/IEC 11770-4:2006 defines key establishment mechanisms based on weak secrets, i.e., secrets that can be readily memorized by a human, and hence secrets that will be chosen from a relatively small set of possibilities. It specifies cryptographic techniques specifically designed to establish one or more secret keys based on a weak secret derived from a memorized password, while preventing off-…

This National Standard of Canada is equivalent to International Standard CEI/IEC 61000-4-4:2004 second edition, 2004-07. 1 Scope This part of IEC 61000-4 relates to the immunity of electrical and electronic equipment to repetitive electrical fast transients. It gives immunity requirements and test procedures related to electrical fast transients/bursts. It additionally defines ranges of test…

This National Standard of Canada is equivalent to International Standard CEI/IEC 61000-4-34:2005. 1 Scope This part of IEC 61000 defines the immunity test methods and range of preferred test levels for electrical and electronic equipment connected to low-voltage power supply networks for voltage dips, short interruptions, and voltage variations. This standard applies to electrical and…

Etablit des spécifications et des caractéristiques techniques uniformes pour les connecteurs. Est applicable à une famille de connecteurs destinés à être utilisés dans des équipements électriques et électroniques; ne couvre pas les connecteurs conçus pour être utilisés aux fréquences radioélectriques.

Composite symbologies are a class of bar code symbology, the principal distinguishing feature of which is that they comprise two or more components, each of which is a distinct symbol, but which contain a set of related data. Typically one component is a linear symbol containing primary data, which may be read on its own in some areas of the application, and the other component(s) is a two-…
