Dear Colleagues:

We are running dogs on a treadmill and wish to trigger acceleratory and
decleratory impulses to the treadmill at various times during a gait
cycle, as triggered by paw contact. Thus, we need to develop a "shoe"
to fit over the paw of dogs that will contain a switch that will feed
into a computer. Does anyone have experience building such a switch
or suggestions on how to design it?
