<p>A process and fail-safe system instantaneously identifies, locates, and help retrieve products and their contents in various locations, products/contents including: computer discs, compact discs, software diskettes, video tapes, audio tapes, and their cases, books, files, boxes, cartons, storage bins, and other containers. A label (122) is placed on each product, and is easily coded to uniquely specify the product or its contents and storage location. Signalling devices (147, 160, 162, 164) are positioned in proximity to the stored products and are in electrical contact with their labels (122), as well as with a central processing unit (CPU) or other equipment used to specify and select the product. When a product is to be retrieved, the CPU or other equipment shuts off the signal devices positioned in proximity to all the products not desired, leaving only the desired or failed items for easy identification and retrieval.</p> |
