As discovered by CanonNews, this is an interesting patent application. Shutter shock is a condition that mirrorless cameras are prone to have if they have a mechanical shutter, especially if they also have IBIS.

A prior patent application may have worked;
[In patent application] an image pickup device that holds a shutter in a floating state so as to be movable only in the traveling direction of the shutter blade by using a spring, and absorbs vibration due to the traveling of the shutter blade.
However, Canon found that approach to be inaccurate and this in this case describes a mechanism that uses electromagnets to move the shutter instead which reduces the amount of vibration caused by the assembly. (Thanks for the clarification – I’ll blame it on 60 hours’...
