Abstract
A system of logic modules providing AND, OR and NOT logical elements most useful in education and entertainment situations where it is important to avoid excessive costs and where speed is not a requirement utilizes electrical continuity and a lack of electrical continuity between pairs of electrical conductors to represent predetermined values of logical variables.
Claims15
A system of logic modules of only electrical conductors including a logical variable produced by the output of any logic module or any of a plurality of logical variables utilized as inputs by any logic module, said system comprising:
- (a) a first, a second, a third, and a fourth electrical conductor;
- (b) an electrical continuity between said first conductor and said second conductor and a lack of electrical continuity between said third conductor and said fourth conductor is a representation of a predetermined value of said logical variable;
- and
- (c) a lack of continuity between said first conductor and said second conductor and continuity between said third conductor and said fourth conductor being a representation of a value of said logical variable that is inverse from said predetermined value of said logical variable.
A system of logic modules utilizing electrical continuity in conductors to represent predetermined values of logical variables, said logic modules being logic circuits in which each logical variable produced by the output of a logic circuit or utilized as an input by a logic circuit is represented by said electrical continuity among four conductors, said system comprising:
- (a) a logic module having a plurality of logical variable inputs and a single logical variable output, said logical variable output being a logical AND function of said logical variable inputs;
- (b) a logic module having a plurality of logical variable inputs and a single logical variable output, said logical variable output being the logical OR function of said logical variable inputs;
- (c) a logic module having a single logical variable input and a single logical variable output, said logical variable output being the logical NOT function of said logical variable input;
- (d) means to create or remove electrical continuity among electrical conductors;
- (e) sensing circuits able to detect electrical continuity;
- and
- (f) connections among said means to detect or remove electrical continuity, said logic modules, or said sensing circuits to indicate the state or value of a logical variable, said connections comprising
- (1) a first, a second, a third, and a fourth electrical conductor;
- (2) electrical continuity between said first and second conductors and a lack of continuity between said third and fourth conductors representing a predetermined value of logical variable;
- and
- (3) a lack of continuity between said first and second conductor and continuity between said third and fourth being a representation of a value of said logical variable that is the logical negation of said predetermined value of said logical variable.
A system of logic modules in which the logical variable produced as the output of any logic module or any of a plurality of logical variables utilized as inputs by any logic module is represented by a representational system comprising:
- (a) a first, second, third, and fourth electrical conductor;
- and
- (b) electrical continuity and a lack of electrical continuity between predetermined pairs of said electrical conductors representing predetermined values of said logical variable.
