As
I explained earlier, a bull fouls by bumping the
gate, falling down, or stumbling. When I tested
the system, I noted several fouls that would have
granted a rider a reride.
If
a bull bumps a gate, for instance, you’ll see
a huge spike in the datastream on one or more
of the accelerometers. The difference between
adjacent samples is continuously monitored on
each of the four channels. A foul is signaled
if any sample-to-sample delta exceeds a calibrated
threshold.
Foul
detection software, which runs in the fast loop,
scans for fouls. If a foul is detected, the optically
isolated output can be triggered to notify the
judges.
