How can linear movement be converted into rotation?

Linear movement --> Rotation

Hey, I'm wondering how many different ways there are to transform linear translation into rotation.
The ones that I'm a familiar with are; rack and pinion, Scotch yoke, Helical spline, crankshaft..
Are there other good ways of accomplishing this? Thank you for your time.

Think you've got the main ones covered. What's the application?

I'm really just exploring different ways to rotate a shaft. Looking for the most compact solution.

You could use a friction drive, which works like a rack and pinion but relies on inter-surface friction rather than positive engagement; think a car tyre. You could also have a hydraulic coupling; displace fluid in a cylinder and use this to drive a hydraulic motor. Probably not what you're after though.
