The Chinese IVAS?
Honestly prefer the M.A.R.S 2.0 its more versatile and much more accessible while also making sure it's light weight for users.
There are multiple such systems in development and even the MARS 2.0 has been superseded by 3.0.
However focusing merely on lightweight and compactness is putting the cart before the horse.
The point of developing these systems is that they want a certain level of capability first. If that capability cannot be met in a more compact package then it has to become more bulky. And if it becomes too bulky to be practically fielded, then it typically gets cancelled or put on life support until newer technologies emerge to enable them to have a lighter profile.
Which is to say, the question for these kind of systems should be to ask what is the level of performance first, and to compare weight and size after that.
