Here's the latest (and possibly last) power of the the TMD device in Singularity
and it's the ability for the TMD to control gravity. The device does go a bit beyond the weapon that Gordon Freeman used in Half Life 2
as you can use it to pull things out of the hands of foes and redirect rockets back at people with the device.
If you want to know more about the game check back later this week as we've got a fairly solid interview with some of the folks behind the game.
