Indicator circuit for storage container for addressable objects
First Claim
1. A storage container having circuitry for enabling remote location and retrieval of documents located in file folders operationally installed within said storage container, each of said file folders having opposing ends, said storage container including a base wall;
- a plurality of upstanding wall members connected to said base wall, said base wall and said plurality of upstanding wall members defining an enclosure volume;
first and second electrically conductive support members each secured to at least one of said wall members in an essentially parallel and mutually spaced manner, the mutually spaced manner between said first and second support members being sufficient to accommodate said ends of a file folder in mechanically supportive fashion;
an electrical input connector secured to one of said upstanding wall members and ohmically coupled to said first and second support members for providing file folder address signals supplied by a source to at least one of said first and second support members, so that said file folder address signals are coupled to any file folder supported by said support members;
a storage container indicator; and
an indicator control circuit for activating said storage container indicator when the file folder operationally installed on said first and second electrically conductive support members has an address matching said file folder address signals and said storage container is electrically coupled to another storage container, said indicator control circuit including a fixed resistance coupled between said electrical input connector and one of said first and second electrically conductive support members, means for sensing a voltage value at a junction of said fixed resistance and said one of said first and second electrically conductive support members, said sensing means having an input coupled to said junction and an output, and a control unit having an input coupled to the output of said sensing means and an output coupled to said storage container indicator for activating said storage container indicator when said voltage value reaches a threshold value.

Abstract
An indicator circuit for a storage container designed to enable remote electronic searching for file folders located within the container. Address signals from a host computer are supplied to the storage container to designate a sought file folder. The indicator circuit is activated whenever a sought file folder is located in a given container. When two or more storage containers are interconnected to receive address signals designating a sought file folder, only the indicator circuit of the storage container containing the sought file folder is activated.
