Abstract

An electronically addressable a-polar document receptacle identification circuit has first and second terminals adapted to be connected to a two conductor data bus for supplying data signals to the terminals and for receiving responses from the circuit. The circuit has a two phase diode bridge circuit with first and second nodes connected to the first and second terminals. The diode bridge circuit is connect to the data signal input of a circuit microcontroller having an output connected to the first and second nodes for furnishing response signals to the nodes. The associated receptacle can be a file folder removably received in a file cabinet or a notebook binder removably received on a cabinet shelf. The circuit will function correctly regardless of the orientation of the terminals with respect to the data bus conductors so a file folder or a notebook binder can be installed in either one of two possible orientations without affecting the functionality of the circuit.

Abstract

A document storage and retrieval system for securely storing documents. A mass storage device contains document identification data and document location information but not the document data. A host computer extracts the document identification data and document location information from the mass storage device and sends this information to a storage cabinet containing the document. Each document is removably stored in a file folder contained in a cabinet drawer. Each file folder has a memory unit which stores an electronic version of each physical document contained in the file folder. The host computer directs the initial storage of a document in folder memory. Thereafter, the host computer is denied access to the electronic versions stored in file folder memory. Access to the electronic versions is only possible using a special reader device.

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 a lock element for releasable engagement with an associated locking device, the microcontroller having a unique object address serving to identify an object secured to the object carrier; a plurality of electrically conductive contact pads in the housing for electrically coupling the microcontroller to a source of object address signals and electrical power signals and a visible indicator coupled to the microcontroller for activation whenever the microcontroller receives an address signal representative of the unique object address. The lock element is a recess formed in a surface of the housing with an abutment edge. The associated locking device is a solenoid having a retractable plunger terminating in a control element which engages the recess. The locking device is mounted adjacent a mounting aperture in a support element, such as a cabinet interior wall. In use, the carrier is inserted into the wall aperture until the control element engages the housing recess, which locks the carrier in place. To unlock, the solenoid is operated to retract the plunger to release the carrier for manual removal.

Abstract

A searchable binder which is operationally compatible with a binder management system having a cabinet with shelves or a file cabinet with file drawers for removable storage of searchable binders. Each binder has a body with front and rear covers and a spine. Inside the body is a binder mechanism for removably retaining sheet media. Each binder has a pair of binder contact mechanisms mounted to the spine at opposite ends, a binder identification circuit electrically coupled to the binder contact mechanisms, and a visible indicator. Each binder contact mechanism has a base element and a sliding element. The sliding element can be manually set to a retracted position in which the sliding element is extended a first distance and an extended position in which the sliding element is extended a second greater distance. In the retracted position, the sliding elements can make contact with conductive elements of a binder cabinet when a binder is placed on a shelf. In the extended position the sliding elements can make contact with conductive support rails of a file cabinet when a binder is placed in a file drawer. When a binder identification signal from a host computer is supplied to the conductive elements or the conductive rails. It is transferred by the binder contact mechanisms to the binder identification circuit. If the signal matches an address code stored in the binder identification circuit, the LED is activated to aid the user in finding the binder.

Abstract

A collective objects management system with enhanced security for objects contained in object receptacles distributed throughout the system. Each object receptacle has a microcontroller with a unique system address which enables generation of a response signal whenever an incoming address from a source is a match. An object container microcontroller periodically polls the object receptacle microcontrollers in the cabinet and stores an updated version of the cabinet object data base. When an object is detected as missing, the object container microcontroller checks whether the absence of the object was authorized by a host computer. If not, a local alarm is activated and the host computer is informed. The host computer can take additional security measures.

Abstract

A secure document receptacle for use in file cabinets having slidable drawers with laterally spaced support rails for removable supporting file folders. The secure document receptacle has a single support brace along the top edge with downwardly opening channels for removable engagement with the drawer support rails. The receptacle has a closed top edge and openings to the interior of the receptacle on the side edge or the bottom edge of the receptacle. Documents can only be inserted and removed via the open side or bottom edges. The receptacle must be partially or completely removed from the drawer support rails before a document can be removed from the receptacle. This interrupts contact between the brace channels and the support rails, an event which can be detected by cabinet sensing circuitry.

Abstract

A drawer organizer for facilitating the location of an item stored in one of several drawers in one or more drawer organizer cabinets. Each drawer has an LED and a display device mounted on a front panel, as well as a CPU and a display device driver. The CPU memory contains the address of the associated drawer and communicates with an associated controller which receives drawer address and display information from a host computer. A user specifies an item to be retrieved from one of the cabinet drawers, the host computer transmits drawer identification signals to the controller, which converts these signals to a drawer address and supplies the drawer address to all drawer CPUs in the cabinet. If the incoming address matches the address stored in CPU memory of one of the drawers, this result is conveyed via the controller to the host computer, which then sends item display information to the controller. The controller forwards this information to the CPU, which relays this information to the display device driver and the information is displayed to the user. The CPU also activates the drawer LED.

The cover has an interconnect mechanism with spring biased translatable conductive probes positioned to mate with the conductive terminal pads of an upper and lower container when two containers are vertically stacked. The combination of the container and cover eliminates the need for individual USB jumper cables when interconnecting two or more vertically stacked containers. An auto alignment feature ensures that the containers are properly stacked with the terminal pads in contact with the conductive probes.
