Patent

CA 2142909

An electronic information aid displays and calcu- lates the relationship between a series of individual in- tegers which may comprise alphabetical and/or numerical indicia or a series of visual and/or aural indicia or a com- bination of any one or more of the integers. The aid has a number of reference rings (23a-23g) each of which is independently rotatable but maintained in a predetermined spatial relationship with each other. Each reference ring (23) includes a number of segments each of which dis- plays indicia which corresponds to an integer. When the rings (23a-23g) are rotated so the segments are aligned into an active strip in accordance with a coding system, the segments will display the interrelationship between the integers. Each segment within the active strip can be ac- tivated to initiate an aural or a visual response.
