I believe Pentax SR is an in-house design. Some of the parts in the SR system is of course standard parts (or manufactured by other companies according to Pentax specification).
One thing that improves all the time is the motion sensors, and now when motion sensors are used in about every mobile device, this tech is advancing faster than ever. FI resolution and response time on the motion sensors have improved quite a lot since Pentax started using SR 8 years ago.
And with faster processor in the camera the response time on the SR system can be improved, and more advanced algorithm can be used for higher precision on the SR motion control.

Yaw & Pitch is what all image stabilization system controls (it's what add most image blur in most shots). Shift shake (X and Y) movement are the extra controls that 5-axis image stabilisation add compared to Pentax 3-axis system. As you see in the video it's mainly for macro, as the effect of shift shake grows the higher the magnification of the shot is.
In most shots the difference in performance between a 3-axis and 5-axis stabilization will mostly be in the efficiency of pitch & yaw correction, not the number of axis in the system have. But the 2-3 extra axis (roll, x and y) does not cost much to implement in a "free floating sensor shift" that Pentax was first in using, and that most other manufacturers has later gone over to.

The 5-axis technology is not something that I believe that Olympus own, It would mostly just be about adding extra accelerometer sensor input to the 3-axis system Pentax use.
But these 2 extra axis do not add much performance to the stabilization unless you shoot macro (and it might add a bit extra stability to video). Translational movement of the camera are usually way to small to affect shots on longer distances.
