%X We give an analogue of the Bessel inequality and we state a simple formulation of the Gr¨¹ss type inequality in inner product -modules, which is a refinement of it. We obtain some further generalization of the Gr¨¹ss type inequalities in inner product modules over proper -algebras and unital Banach -algebras for -seminorms and positive linear functionals.
