  • Modular controller housing having movable card guides
    Patent number: 6771513
    Abstract: The specification discloses a controller housing that utilizes card guides that may be installed and removed without the use of tools. Various arrangements of the controller housing with and without the card guides allows for the controller housing to accept electronic circuit cards of varying sizes. Thus, if a manufacturer desires to increase the number of points on an input/output card, for example, those additional points need not necessarily be contained in a card having the same form factor. Instead, the manufacturer may provide a larger form factor card and that card may be inserted into the controller housing by appropriately adjusting the location of the card guide within the particular opening into which the new card is to be inserted.

  • Method & system for limiting use of embedded software
    Publication number: 20030163712
