Gary, what do you call new technology?

When hypnodisk shattered Stealth in series 3, the disk weapon was new technology
Antrax/Raven and Behemoth were among the first to use NiCd 7000 mAh cells. Equally new.
When Hardox was introduced in RW, it was new technology.
When Gravity started flipping in Heat D series 7, it was new technology and dangerous too boot.

When is something new technology? Or when is it just cunning use of existing possibilities?
