Well the US patent is already awarded, this is the WIPO application. My US patent office login has expired and I'm too lazy at the moment to get it back, because I don't see two of the images the application refers to.
Generally, it appears to be an improvement on the standard CF card/SD Card connector system with option for a third interface type.
If I'm reading it correctly (and I haven't spent much time on it) they propose a socket/connector that could
take a card and interact with it in one of two modes
Read only (like a game cartridge)
R/W (like an SD card)
And would in fact be compatible with both CF and SD cards
as well as a third form factor card utilizing some additional contacts.
So possible example for use in a pleo - a cheap ROM card memory for static personalities, or a R/W like our SD cards now all with one slot connector and some 3rd option which I didn't read too far into.
This is not the whole story - they reference music usage and other entertainment usage examples in the text, it was intended
for much wider usage than pleo by design.
