Has anyone here actually had an "incident" occur while riding that left them physically unable to use a cellphone and the incident detection device/app combination(s) sent out an alert that resulted in the first (or any) appropriate response from an emergency agency?

If not, do you know of any credible reports of the incident detection equipment under discussion actually resulting in the initial emergency response or aid to any "incident" incapacitated cyclists? Has any "incident alerted" spouse become the actual first responder or been the first to notify 911 personnel of an incapacitated cyclist?
