Tagging apparatus associated with applying and reading a tag adapted to store a number. The tag comprising a plurality of substantially identical two dimensional arrays of dots, each array being indicative of the number for improving tag detection; each arrays comprise a plurality of clusters, each cluster representing a predetermined symbol being indicative of a part of the number. An etching apparatus, for creating a pattern of dots, comprising a plurality of laser sources held in a manifold defining any one or more of a vector grid, or array grid. A tagging reading apparatus comprising a lens element being adapted to control focus, zoom and ingress light; an image capture element for obtaining image data; a processor element adapted to apply one or more digital processing functions to the image; the processor element being adapted to calculate code data indicative of the tag number.

Tag reading apparatus and a method of reading a tag

A base for a chair, the base comprising a chassis ( ), at least one landing ( ) operatively connected to the chassis; a carrier ( ) for reduced friction sliding along the landing transverse to the forward facing direction of the occupant; the carrier being adapted to support a pedestal ( ) upon which the chair is operatively mounted. The base may include a foot rest ( ), brake means ( ) to prevent sliding when the seat is not occupied and wheels between the chassis and floor to permit movement of the seat transverse to the sliding of the carrier. The wheels may be lockable. The landing may comprise an inverted U channel in which rollers slide from which the carrier may suspend underneath the chassis.
