Abstract: A system for hanging implements on a wall which employs a hanging component formed of thin steel wire having two wire legs integrally joined to and spaced apart at a limiter portion. In a shelf supporting embodiment, bores or paired channels are provided within a shelf standard at a downwardly depending acute angle. The standard then is used with an elemental drill to form corresponding paired channels through a drywall surface. The wire bifurcate hanging components then are inserted through these channels at the noted acute angle to support a standard against a wall. The acute angle evokes an inwardly directed vector component providing a very stable and relatively high load bearing capacity. Removal of the shelf system from the wall is simply accomplished by lifting upwardly to reveal only small paired channel openings which are easily covered or resurfaced. A continuous strap based self supporting arrangement simplifies the mounting to and supporting of shelves from spaced apart standards.

After a package is dispensed, a code reader determines the code of the dispensed package and verifies whether the code on the dispensed package matches the code of the requested package.

Abstract: Electroluminescent lamp designs and methods of fabricating electroluminescent lamps. Lamp designs provide laminar style lamps that include an electrically conductive layer with one or more openings therethrough separated by conductive elements. The openings preferably have a minimum edge to edge distance of less than about 0.005 inches and the conductive elements have a width of less than about 0.002 inches. Lamp designs also include "iso-planar" lamps that contain an electrically conductive layer with one or more channels separating the layer into two or more electrically conductive elements and an electroluminescent material disposed between the electrically conductive elements. The laminar style lamps and iso-planar lamps may be fabricated using printing techniques and the iso-planar lamps may also be fabricated using etching techniques. Both printed laminar and iso-planar lamps may be permanently reshaped using sheet forming techniques such as vacuum-forming or drape-forming.
