Saw this on eBay yesterday:
https://www.ebay.com/itm/292892744768?ul_noapp=true

Looks interesting for the price (same price as a VPC1!). However, it uses an older sensor system which does not support half-pedaling. They said they could upgrade the sensors, which of course translates to a higher price.

There's also a video on the page that shows how they convert dilapidated acoustic pianos into digitals.

Woah.... That's the CG project only with an upright...

Indeed but I guess it’s a system similar to Pnoscan only under the keys.

It's an old system made by QRS, who also makes PNOscan. The seller is also selling the system separately. As you can see in the listing, it's a pretty old system.

I guess you missed the link I posted:
https://www.ebay.com/itm/KS-1B-MIDI...4?hash=item44427bd1c6:g:BeIAAOSwimddQjtb

They're optical. The keys push down a lever that blocks a light beam. I imagine the sensor determines the position of the key based on the amount of light that is being blocked.

And the modern version does not use any springy levers:
