Definitions

• the invention relates to a monitoring system, and especially, a system to identify and monitor the location of library items, such as books.
• a user can only borrow a certain number of books. If that number of books have been deposited in a bookdrop, the borrower is unable to borrow any further books until after the books deposited in the bookdrop have been scanned as being returned.
• the total number of books which may be borrowed by a user may be limited to four.
• a library monitoring system comprises a number of borrowable items, each item having a radio frequency identification device mounted thereon, the radio frequency identification device having a unique identification code; a processing unit coupled to a database containing an indication of the location of each library item, and to a borrowing location, a borrowed item returning location and a returned item sorting location; wherein the borrowed item returning location comprises a receptacle into which the borrowed item may be inserted, the receptacle comprising an antenna which detects an insertion of a library item having a radio frequency identification device mounted thereon, the borrowed item returning location, in response to the insertion of a library item into the receptacle, detecting the identification code and sending the identification code corresponding to the returned library item to the processing unit, the processing unit, in response to the received identification code, updating the information on the database relating to the returned library item to indicate that the returned library item has been returned to the library.
• An advantage of the invention is that by having a library system in which radio frequency identification devices are mounted on the items in the library which may be borrowed, it is possible to detect when the borrowed items are returned to the library as soon as they enter a designated area.
• the radio frequency identification device may also be used as a security feature, such that if it is attempted to remove a library item from the library or from an area within the library without authorisation this is detected by the processing unit which generates an alert signal which may be visual or audio.
• the returning location when the returning location detects that a library item has been inserted into the receptacle, the returning location also sends a signal to the processing unit to indicate the location to which the item has been returned.
• the library system further comprises a conveying mechanism between the returning location and the sorting location, the conveying mechanism conveying returned items from the receptacle to the sorting location.
• the sorting station comprises a radio frequency identification device reader which detects a library item to be sorted in the sorting station and sends an identification signal corresponding to the item to be sorted to the processing unit, in response to which the processing unit displays on a display device in the sorting location, sorting information to enable an operator in the sorting location to identify the location to which the library item is to be returned.
• a radio frequency identification device reader which detects a library item to be sorted in the sorting station and sends an identification signal corresponding to the item to be sorted to the processing unit, in response to which the processing unit displays on a display device in the sorting location, sorting information to enable an operator in the sorting location to identify the location to which the library item is to be returned.

• the books are then removed from the receiving bin 35 by an operator 36 and passed across the antenna 10 to permit scanning of the RFID located on the book 34 by the reader 9.
• the PC receives identification information concerning the book 34 being scanned from the reader 9 and passes the identification information to the host computer 1.
• the host computer 1 determines the correct location of the book 34 being scanned and illuminates a light 36 on a sorting compartment to indicate the area of the library in which the book 34 is to be returned to.
• the operator 36 places the book 34 in the correct compartment for return to the correct section of the library.
• a user may borrow a book 34 from the library by inserting the library membership card or identity card into the barcode reader 12.

• the borrowing station After inserting the library membership card or identity card, the borrowing station displays instruction on the screen and at the correct point in the borrowing procedure, the user places the book 34 above the RFID antenna 10 on the surface 24. A receipt is printed by the mini-printer 11 as each book is scanned.
• the PC 21 with the identification information for the book 34 from the reader 9 and the identification information of the borrower from the barcode reader 12, passes this information to the host computer 1 to permit the host computer 1 to update a database to indicate that the book borrowed is now located with the borrower corresponding to the borrower's identification card.
• the user has finished scanning all the books they wish to borrow they remove the library card or identity card which activates a cutter (not shown) in the mini-printer to cut the receipt and the receipt of books borrowed is dispensed to the user.
• the user may present the book to one of the counter stations to enable the book to be scanned by a member of the library staff as being borrowed by that user.
• the user When a user wishes to return the book 34, the user goes to a returning station 2 and drops the book 34 through the book slot 33.
• the book 34 then passes over the RFID antenna 10 in the chute 32 on its way to the conveyor system 8.
• the PC 30 reads the identification code of that book from the reader 9 and passes identification information to the host computer 1.
• the host computer 1 then updates its database to indicate that the book 34 dropped through the book slot 33 is now located in the library.
• the host computer 1 can allocate a number of different locations to the book 34 such that when the book 34 enters the book slot 33 the book is entered in the computer database as being located at the returning station 2.
• the computer can update the database to indicate that the book 34 has been sorted and is located in a sorting compartment.
• antennas 10 and readers 9 may be located throughout the library. These readers 9 may be interrogated periodically by the host computer 1 to determine all the books 34 in the vicinity of that particular reader 9 and update the database with the locations of the books detected in the vicinity of that reader. This has the advantage of permitting the location of all the books 34 in the library to be maintained on a virtually real time basis.
• the same library system may be used with any other item which may be borrowed from a library, such as compact discs, cassette tapes and videos.
• this system has the advantage that returning stations may be located outside the library itself and provided that the PC 30 is connected to the host computer 1 by a suitable communication link, the host computer 1 can determine the location of the bookdrop in which a book 34 has been returned. It is possible that certain bookdrops outside of the library may not be connected to the library by a conveyor mechanism 8 in which case the books may be collected manually, for example, by delivery van or courier, or other collection agencies to return the books to the library.
• Advantages of the invention are that by using an RFID based system it is not necessary to manually scan each book during borrowing of the book, returning of the book and sorting of the book.
• the RFID tag can also be used as a security device to minimise the risk of books being removed from the library without authorisation.
• the security feature is deactivated when a user borrows a book at a borrowing station 3 and is reactivated when the book is returned to the library, either at a returning station 2 or a sorting station 5.
• This security feature can be enable by using a memory location within an ' EEPROM in the RFID tag.
• a typical EEPROM in a RFID tag will have a 128 bit memory. Approximately 75% of the memory locations are used to identify the library item. For example, if the library item is a book the identification information may include the Dewey decimal number and/or the Library of Congress classification and the library branch code to which the book belongs.
• One of the remaining memory bits is allocated to indicate whether the removal of the library item from the library has been authorised. Hence, if the memory location contains a "0" it indicates that removal from the library has not been authorised. However, if the memory location contains a "1" it indicates that removal from the library (for example, by an authorised user borrowing the book) has been authorised. Hence, if a person tries to remove a book from the library which has not been officially borrowed, a scanner at or adjacent to the exit of the library detects the "0" in the security memory location of the EEPROM and triggers an alarm. If the scanner detects a "1" in the security memory location of the EEPROM, the system knows the book has been officially borrowed and no alarm sounds.
• This feature operates by the scanner in the borrowing station 3 writing a "1" to the memory location when an item is borrowed, and the scanner in the returning station 2 writing a "0" to the memory location when the book is returned to reactivate the security feature.
• Suitable RFID tags that may be mounted on the books 34 are tags such as those manufactured by Motorola Indala Corporation, such as the mini disk tag model IT-52E or the high stress tag model IT-54E.
• Suitable readers 9 that may be used with the library system include Motorola Indala Corporation readers such as the IR-24E or the IR-36E long range reader, the IR-50E general purpose reader or the IR-12E compact reader.
• hand held readers such as those manufactured by Motorola Indala Corporation, such as the IR-200E Geo Technology reader and the IR-2E focus point reader and the IR-100E portable reader, may be used for portable applications, such as manual scanning of books if necessary.
