Claim 12

An information retrieval and display system which can be employed in a learn-then-perform mode of operation, said system comprising a module which has: (a) a data reader for an encoded data storage device, and (b) a screen for displaying information generated from data retrieved from said data storage device; said data storage device having means for storing in digital form data corresponding to: (a) a multiple choice menu; and (b) an item of information which can be retrieved from the data storage device by a system user making a choice from said menu, said system further comprising: (a) a directory means which is separate from and physically independent of said module, and (b) control means having means which, upon said choice being made: (c) causes said data reader to read data identified by said choice from the storage device, and (d) causes said item of information to be generated from said data and presented on said screen; said directory means including a different, multi-digit numerical identifying code and descriptor for each menu choice corresponding to an item of retrievable information; and said control means comprising: (a) control elements which are activatable by said system user to generate signals representing the distinct identifier code for the user selected item of information, (b) buffer means for storing said signals in the order in which they are generated, and (c) means for identifying the last in the series of those signals representing the identifier code and then retrieving the signals from said buffer in the order in which they were stored in said buffer and activating said data reader to retrieve from said storage device the data from which the selected item of information can be generated.

Claim 13

A system as defined in claim 10 in which said control elements are located on board said module.

Claim 14

A system as defined in claim 10 in which said control elements are incorporated in a remote control.

Claim 15

A system as defined in claim 12 in which said control elements comprise a numerical key pad.

Claim 16

A system as defined in claim 10 in which the information stored by said data storage device provides a hierarchical array of multiple choice menus, at least one item of information being retrievable by making a choice from a bottom level menu in said hierarchy.

Claim 17

A system as defined in claim 10 in which the directory means comprises an index card.

Claim 18

A system as defined in claim 10 in which said directory comprises a coded set of cards.

Claim 19

A system as defined in claim 10 in which said directory means is in book form.

Claim 20

An information retrieval and display system which can be employed in a learn-then-perform mode of operation, said system comprising a module which has: (a) a data reader for an encoded data storage device, and (b) a screen for displaying information generated from data retrieved from said data storage device; said data storage device having means for storing in digital form data corresponding to: (a) a multiple choice menu means; and (b) first and second items of information which can be retrieved from the data storage device by a system user making choices from said menu means; and said system further comprising: (a) a directory means which is separate from and physically independent of said module; and (b) control means having means which, upon a choice being made from said menu means: (c) causes said data reader to read data identified by said choice from the storage device; and (d) causes said item of information to be generated from said data and presented on said screen; and said control means including a different identifying code and a descriptor for each menu choice corresponding to an item of retrievable information; and said directory means comprising a single dedicated control element which can be employed by a system user during or following the presentation of said first item of information to reset said control means for the acceptance of the identifier code corresponding to the second item of information.

Claim 21
