Abstract: An electronically addressable object carrier for enabling the management of removably suspended objects, such as keys, distributed in an object location space, The object carrier includes a housing having an object retention element for securing an object to the object carrier and at least one through aperture for removably receiving an electrically conductive suspension member capable of manifesting object address signals and power signals supplied by a source; a microcontroller carried by the housing, the microcontroller having a unique object address serving to identify an object secured to the object carrier; an electrically conductive element located in the at least one aperture for electrically coupling the microcontroller to the electrically conductive suspension member when the aperture is removably received on the electrically conductive suspension member; and a visible indicator coupled to the microcontroller for activation whenever the microcontroller receives an address signal representative of th

Abstract: A documents management system with remote location and retrieval of documents contained in file folders positioned in file drawers in a collection of file cabinets. Each document has an RFID tag containing a document identifier and the contents of the document stored in a read-only memory. Each file folder has a circuit containing a unique identifier for that folder. Each file cabinet has a control unit which searches for a specific file folder in response to receipt of a file folder request from a source. If the folder is found, each cabinet has an R.F. reader which searches for a specific document in response to receipt of a document request from the source. If the document is found, the R.F. reader extracts the document contents and transmits them to the source.
