Abstract
Abstract A learning apparatus in which a memory contains a first plurality of data units and a second plurality of data units each of which is related to a unit of the first program. Switches are provided for switching between the first and second pluralities of data units and for switching between the units within the selected plurality. Reading means are provided for reading a designated unit of data from the memory, based on a signal from the operation switch, thus making it possible to access and reproduce any desired program or articles related to the program. In another embodiment, a control memory holds the addresses of the data units, and the reading means obtains the address of the selected data unit from the control memory and reads the data at that address. The apparatus is uniquely suited for audio teaching material, such as languages, but may be used with any information which may be organized into logically related units.

Claim 1
Independent Claim
167 words
An apparatus comprising: a memory containing a first plurality of data units, wherein each of the data units in the first plurality of data units is first language audio teaching material, and a second plurality of data units, wherein each of the data units in the second plurality of data units is second language audio teaching material, and wherein each of the data units in the second plurality of data units corresponds logically to a unit of said first plurality of data units; switching means for selecting among units in said first and second pluralities of data units, wherein the switching means comprises a first set of cursor operation switches for switching between logically corresponding data units in said first and second pluralities of data units, and a second set of cursor operation switches for switching between data units within said first plurality of data units or within said second plurality of data units; and reading means for reading each selected unit of data from said memory.
Claim 2
Independent Claim
167 words
An apparatus comprising: a memory containing a first plurality of data units, wherein each of the data units in the first plurality of data units is first language audio teaching material, and a second plurality of data units, wherein each of the data units in the second plurality of data units is second language audio teaching material, and wherein each of the data units in the second plurality of data units corresponds logically to a unit of said first plurality of data units; switching means for selecting among units in said first and second pluralities of data units, wherein the switching means comprises a first set of cursor operation switches for switching between logically corresponding data units in said first and second pluralities of data units, and a second set of cursor operation switches for switching between data units within said first plurality of data units or within said second plurality of data units; and reading means for reading each selected unit of data from said memory.
Claim 3
Dependent Claim
209 words
A learning apparatus comprising: a memory containing a first plurality of data units, wherein each of the data units in said first plurality of data units is first language audio teaching material, and a second plurality of data units, wherein each of the data units in said second plurality of data units is second language audio teaching material, and wherein each of the data units in said second plurality of data units corresponds logically to a unit of said first plurality of data units; a control memory which holds addresses of data units in said first and second pluralities of data units; switching means for selecting among data units in said first and second pluralities of data units, wherein said switching means comprises a first set of cursor operation switches for switching between logically corresponding data units in said first and second pluralities of data units, and a second set of cursor operation switches for switching between data units within said first plurality of data units or within said second plurality of data units; and reading means for reading an address of a data unit selected by the switching means from the control memory and reading a unit of data which is located at said address in said memory.
Claim 4
Dependent Claim
209 words
A learning apparatus comprising: a memory containing a first plurality of data units, wherein each of the data units in said first plurality of data units is first language audio teaching material, and a second plurality of data units, wherein each of the data units in said second plurality of data units is second language audio teaching material, and wherein each of the data units in said second plurality of data units corresponds logically to a unit of said first plurality of data units; a control memory which holds addresses of data units in said first and second pluralities of data units; switching means for selecting among data units in said first and second pluralities of data units, wherein said switching means comprises a first set of cursor operation switches for switching between logically corresponding data units in said first and second pluralities of data units, and a second set of cursor operation switches for switching between data units within said first plurality of data units or within said second plurality of data units; and reading means for reading an address of a data unit selected by the switching means from the control memory and reading a unit of data which is located at said address in said memory.
