[nagdu] Ultrasonic mobility devices

[Tracy Carcione]

Hi Rebecca.
Really?  I was wondering if one could use it to tell if a bus seat was
entirely unoccupied, or if a table was unoccupied at the pizza place. 
Your experience would say no?
Benny will point out a bus seat where one is empty, but I prefer an
entirely empty seat so I can sit by the window and Ben doesn't get his
paws or tail in the aisle.
