The first  weaponry "laser emitter" 
Was that inspired by Star Trek too? Did'n know that.
and the touchscreen PC, do i need a reference for that one
Yes... Does such a thing work? (LOL)
Lol it does, my friend who lives just down the street from me has 22' MSI touch screen  ;) THE COOLEST thing I've ever seen got to admit... when I saw it first, the best I could describe it in two words was I think 'absofuc.inglutely awefuc.ingsome'  

 although it's kinda hard to get used to it at first...
Oh and I saw documentary on BBC Knowledge about cloak 

 the field tested such thing on a guy dressed in white jacket/jumpsuit, behind him there was a camera recording environment and projector in front of him projecting everything that's behind him on his clothes, thus he appeard almost invisible but that was hardly a cloak to me
