Pentax in-lens Ring motor patent

I found an interesting patent for a magnetic in-lens ring motor from Pentax. We may have some cool stuff coming in the future. Looks like they are leveraging their magnetic actuatuor technology as much as they can which is wise (the mirror actuator in the K-7 for instance is also a novel magnetic actuator, not to mention the whole SR platform )
