Hi guys. I know Iikka (Fingers) has been very busy with other things (like Valve stuff), so I'll mention this to him. I'm sure he'll want to check in. Give it a couple of days. Sorry I can't help. I'm just the piano player.
I think the hypervision flag only works on items that are in your cargo hold, not on systems that are installed.
I don't remember what the PAR1 on sensors does (if anything). It's set to zero on all the sensor items. It's possible it was intended to be used for something (like different range in open space vs. nebula) but never was.
