Hi, I'm Marco, CTO of P.A.T. Avionics.
I am also a home builder and I just completed my Asso. An Italian designed experimental airplane in many ways similar to an RV. A friend of mine flagged this thread forme and I thought to provide some info about our patent pending product.
Our laser projector is not a common laser projector for retail use, it's an OEM laser with ad hoc specs enabling us to use it on aircrafts. Just as an example we spent more than 10 months to resolve issues such as heatsinking, enclosure design and interface development. Our G-HULP is now able to sustain 4 or more hours over 100F? environment temperature and it can easily be interfaced with the most used avioncs systems such as Dynon Skyview.
Screen we use is a special proprietary glass enabling the reflection, like a mirror, of just the laser waves. This glass has 80% transparency and 100% of laser graphics saturation.
Regarding infinity focus, although we have the capabilities we decided not to implement it for these 3 reasons:
1- to use infinity focus, pilot need a special training. Normally a sport pilot can't have this type of training and their CFI?s in general do not have military training.
2- With a traditional instrument panel, pilot is forced to look down for the instrument or to the exact EFIS data point. This type of head movements and scanning can take up to a few seconds, even more with pilots using smartphone and tablet devices. With a ?non-infinite? HUD a change of focus from the pilot's eyes is required, however it occurs naturally in about 200 milliseconds and at the speeds of sport flying nothing really happens in that timeframe. (i.e.experimental aircraft pilots are probably not planning to knock down an enemy

).
3- On top of that, infinity view heads up display systems are less energy efficient, heavier, bulky and in general less visible in bright sunlight than our solution.
If anyone wants to try our product please let me know and we will do our best to make it easier for you.
Hope this helps!
Marco
