  Recently, Maccone and Pati [Phys. Rev. Lett. {\bf 113}, 260401 (2014)]
derived few inequalities among variances of incompatible operators which they
called stronger uncertainty relations, stronger than Heisenberg-Robertson or
Schrodinger uncertainty relations. Here we generalize their study to get
infinite number of such inequalities and propose that only one of them may be
the correct uncertainty relation between incompatible operators. We get back
well known uncertainty relations of Heisenberg-Robertson and Schrodinger under
certain limits. We also reexamine the conclusions of Maccone and Pati and
comment on their work.
