Abstract
An indirect measurement model is constructed for an approximately repeatable, precise position measuring apparatus that violates the assertion, sometimes called the Heisenberg uncertainty principle, that any position measuring apparatus with noise epsilon brings the momentum disturbance no less than hbar/2epsilon in any input state of the apparatus.
