Abstract

An electrically encoded system is provided which includes a base with a first matrix mounted on the base and formed of a first plurality of electrical conductors spaced and insulated from one another, and which may also include a second plurality of electrical conductors mounted on the base which are spaced and insulated from one another and which bridge selected pairs of the conductors of the first plurality. However, the circuit is still not complete, and a second matrix which is positioned externally to the base is required. Adjustments must be made to the second matrix in order to complete a circuit through the first matrix and through the conductors of the second plurality so as to provide an output indication.

Claims

1. An electrically encoded system including in combination:

a base;

a first matrix mounted on said base comprising a first plurality of electrical conductors spaced and insulated from one another;

a second plurality of electrical conductors mounted on said base spaced and insulated from one another and respectively bridging and interconnecting selected pairs of the conductors of said first plurality in accordance with a predetermined code;

a plurality of electrical terminals mounted on said base and electrically connected to respective ones of said conductors of said first plurality;

a pair of output terminals mounted on said base and connected to a pair of conductors of said first plurality of said first matrix;

a second matrix positioned externally of said base and controllably establishing electrical connections between selected pairs of said electric terminals to interconnect the remaining pairs of the conductors of said first plurality not interconnected by the electrical conductors of said second plurality and to complete a circuit across said output terminal only when a particular program has been implemented in the control of said second matrix.

2. The combination defined in claim 1, and which includes an output circuit positioned externally of said base, and connected to said output terminals for providing an indication when said circuit has been completed across said output terminals.

3. The combination defined in claim 1, in which said base is formed of a plurality of insulated sheets of plastic material, or the like, each of a size to be conveniently carried on the person of the user, said insulated sheets being laminated to one another to constitute a card having a multiplicity of layers, and in which said first matrix is formed on one of said layers, and said second plurality of electrical conductors are formed on another of said layers.

4. The combination defined in claim 3, in which one of said layers includes a plurality of metallized holes extending therethrough, and in which each of said electrical conductors of said first matrix extends between and is connected to corresponding pairs of said metallized holes, and in which said conductors of said second plurality are positioned to bridge and to be connected to selected pairs of said metallized holes.
