LOGICAL MODULE Russian patent published in 2007 - IPC G06F7/00 

FIELD: computer engineering, possible use for designing automatic devices, functional units of control systems, etc.

SUBSTANCE: in accordance to invention, logical module, containing an output, features additionally introduced first, third, fifth keys, made closing, and second, fourth, sixth keys, made opening, while input of fifth, input and output of sixth keys are connected respectively to combined outputs of first, second, combined outputs of third, fourth keys and combined outputs of firth key, to output of logical module, connected by first, second informational and first, third, second adjusting inputs respectively to control input of first-fourth, control input of fifth, sixth keys and input of first, input of fourth keys, combined inputs of second, third keys.

EFFECT: expanded functional capabilities due to realization of any one of three simple symmetric Boolean functions τ₁=х₁∨х₂∨х₃, τ₂=x₁x₂∨x₁x₃∨x₂x₃, τ₃=x₁x₂x₃ or of three fundamental symmetric Boolean functions
