[General] Do any Sci-Fi's have a device that adjusts gravity to the user personally wearing it, that varies from planet to planet, and how would it work?

In most scifis when characters are visiting any planet they all seems to be walking just fine, never attempting to adjust to the new and different gravity.

I've seen in some cases a race of aliens would wear very heavy armor when theyre off world to simulate the heavy gravity of their home planet 

Maybe an unspoken scifi rule (like everyone has universal translators) is also everyone wears a gravity adjuster - that increases or lessens your localized gravity 

**My questions are:**

* Do any Scifi's mention a device like this?
* How would it work (especially the lessening of gravity)

Star Trek life support belts come with antigrav/gravity manipulation functions.  You see this most often when crewmen beam onto powerless ships or stations and walk as if they're on a planet.

One of the main viewpoint characters in the Sector General documentaries (about a hospital space station serving a wide variety of sentients) is a member of a flying race from an planet with a tenth of Earth's gravity.  She uses gravity nullifiers to fly about the station.
