And my point wasn't about grammar either; it was about the fact that you really used to able to get away with cr*p, and the bar is at least fractionally higher. In this context, there's so much prior art within a couple of minutes of googling, that unless there's something cunning (which let's hope there is) it may fall at that bar, and I had not seen any discussion elsewhere of this test.

OK, my bad; I meant a 'higher' bar...

BTW, feel free to contact me, if need be under NDA: RF expertise; teach new technology ventures; entrepreneur myself. If you can outperform inertial sensing, I'll buy it for my app as well. But above all, you need an Angel with relevant expertise.

First read Paul Graham's site: it's about the best collection of how to do a startup there is out there. Second: find an 'Angel', who's prepared to (a) sign an NDA and (b) who has some relevant expertise - there's lots of Angels out there with deep RF know-how Third: in parallel, go deep on the IP; as an electronics engineer, it's unlikely that if it's that simple there's no relevant prior art: try US patent number 5708427, 7319428, 5558091 - OK none of them are spot on but they're close enough and this has to be novel enough to be 'non-obvious' which is a high bar nowadays

I like something allegorical. Our company is Endeavour Partners; we use the names of Captain Cook's ships. My previous company was Mercator Partners; we used contemporaneous names of countries for servers, of major cities for desktop machines, and of ports for portable machines. I'm the CTO of a startup involved with horses: servers are racetracks; workstations are famous racehorses.

Eeee, I used to dream of living in a hole in't ground. We used to live at bottom of lake, hand coding assembly language in hex, rotating bits with a hand crank and communicating it using signal flags or semaphore. And then sysadmins and punch card operators would come and chop us into little bits with paper tape readers and dance on our line printer reams. And you tell young people this today, and they just don't believe you
