Collective objects management system with improved object data base management

摘要

A collective objects data base management system for objects such as documents contained in file folders in drawers of file cabinets. Each file folder has an electrical circuit with a visible indicator mounted on the file folder. Each folder circuit has an object receptacle microcontroller with a unique system address which enables generation of a response signal whenever an incoming address from a source is a match and activation of the visible indicator. An object container microcontroller periodically polls the object receptacle microcontrollers in the cabinet and stores an updated version of the cabinet object data base. The cabinet object data base contents are sent to a host computer, which maintains the system data base.
