DOHC eventually became standardized, when companies were using Twincam, and even Quadcam for some of their motors.
Variable lift with cam phasing, is how I would describe Toyota's application of Valvematic.
There's pretty much only the three mechanisms I can think of.
Variable Valve Lift (Valvematic).
Cam Phasing (VVT-i)
Cam profile switching (VTEC)
Most of the named systems like VVTL-i, iVTEC, Valvematic, etc... are just combinations of these.
It's just wishful thinking on my part...
