mobile accelerometer

[Mike Kerner]

Right - it's the deceleration and delay that I'm hoping I can use to
determine that the forklift has stopped moving.
And yes, there are simpler ways to do everything - but if I was going for
simple, I would have stationary, wired workstations running our ERP
software, not a mobile app running on the truck.

On the first day, God created the heavens and the Earth
On the second day, God created the oceans.
On the third day, God put the animals on hold for a few hours,
   and did a little diving.
And God said, "This is good."
