Abstract
Abstract A pair of information display boards are provided and upon each of which there is a multiplicity of information wherein each bit of information on one board is related to a bit of information on the other board. Each bit of information upon the two boards is associated with an electrical contact and the contacts thus associated with the two information boards are made comparable to each other by means of selectively replaceable circuit boards having comparable circuit continuity. Affirmation of correct comparison is by means of switching effected by simultaneously touching a pair of manipulatable probes to said contacts at the two information boards respectively, said probes being in a series circuit through a power supply and signal means.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
194 words
A programmed educational comparator wherein a pair of electrically operable probes are manipulated and intelligently applied to area contacts representing comparable bits of information, and including: a. a frame having marginal board receiving means for supporting and displaying an information and circuit board, and having two series of exposed electrical contact areas; b. two comparable series of receptacle contacts carried by the frame along at least one margin of the board receiving means; c. the information and circuit board replaceably supported on the frame by said receiving means and carrying bits of comparable information aligned with the exposed eleCtrical contact areas adjacent the board receiving means; d. a program means carried by the information and circuit board and having two series of conductors interconnected in correct association with the bits of comparable information thereon, said conductors being individually connected with the two said comparable series of receptacle contacts respectively; e. and a pair of manipulatable electrically conductive probes in a powered circuit through an alarm means, whereby an intelligent selection of comparable information accompanied by correct engagement of said probes with exposed contact areas associated with comparable information is affirmed by said alarm means.
Claim 2
Dependent Claim
194 words
A programmed educational comparator wherein a pair of electrically operable probes are manipulated and intelligently applied to area contacts representing comparable bits of information, and including: a. a frame having marginal board receiving means for supporting and displaying an information and circuit board, and having two series of exposed electrical contact areas; b. two comparable series of receptacle contacts carried by the frame along at least one margin of the board receiving means; c. the information and circuit board replaceably supported on the frame by said receiving means and carrying bits of comparable information aligned with the exposed eleCtrical contact areas adjacent the board receiving means; d. a program means carried by the information and circuit board and having two series of conductors interconnected in correct association with the bits of comparable information thereon, said conductors being individually connected with the two said comparable series of receptacle contacts respectively; e. and a pair of manipulatable electrically conductive probes in a powered circuit through an alarm means, whereby an intelligent selection of comparable information accompanied by correct engagement of said probes with exposed contact areas associated with comparable information is affirmed by said alarm means.
Claim 3
Dependent Claim
61 words
The programmed educational comparator recited in claim 1 and wherein the program means of the information and circuit board is comprised of a series of parallel and right angularly related conductor strips at opposite sides thereof, there being connectors projecting through the board to interconnect the opposite side strips, establishing circuit continuity associated with information on said information and circuit board.
