That isn't exactly what Heisenberg said. The dispersion relations hold even if the "observer" isn't sentinent; maybe it's only a crystal. There are also observations that don't disturb the object.
OK, I'll bite. Like when Schrödinger's Cat looks at it?
Seriously, though, I've imbibed some Pumpkin Ale (left over from Thanksgiving) and it's slowed my recall. Examples of this on a quantum scale object?
