Transport device used by Ansata terrorists on planet Rutia IV in 2366. Ansata members were able to conduct interdimensional, folder-space transports that escaped detection by Rutian authorities. The inverter had the side-effect of causing cumulative damage to the DNA of those using it. The damage would accumulate and eventually be fatal with continued use. Lieutenant Commanders Data and La Forge were able to find the inverters' power source with an adaptive subspace echogram. The echogram detected the subspace pressure modulations that usage of the device also caused.
