We introduce the concepts of T-generalized state machines and coverings of products of them. Also some of algebraic properties of them are investigated. Finely some products such as direct sum and sum of Tgeneralized state machines are introduced. An interesting distributive property of cascade product over the sum of Tgeneralized state machines concern to covering of T-generalized state machin...
