Product storage and retrieval system
A system for easily locating goods stored in a storage area including a computer coupled with a radio frequency transmitter or transceivers and goods placed in containers that are coupled to hangers that each has distinct electronic addresses. The hangers each have a hook that allows the hangers to be stored on rails coupled to racks in a storage area. The identifications of the goods and the electronic addresses for the corresponding hangers are associated with each other and stored on a computer database. When a user wants to pick up goods stored in the containers, the user inputs the identification for the goods and the computer will cause the radio frequency transmitter to emit a data packet that includes a search address and illumination data. The hangers each compare the search address to the electronic address and if there is a match, the hanger illuminates the light according to the illumination data. The system notifies the user of the color and flash pattern and the goods can then be easily found by locating the hanger having the corresponding illumination.
