I think Chailey used to do a collision avoidance system , not sure if they withdrew it from the market in 1998 whe CE Directive came into being. I don't know how it works, hence not sure how you would risk assess for such an environment.

Dear All
I received this request recently. We could use an ultrasound parking aid
for a car but does anyone know of an AT product?
regards
Mark Hawley
A has contacted me, as her mother is in a Nursing Home and is wheelchair
dependent. Her vision is deteriorating and she is knocking into things. She
asked if I knew of a 'sonar' device which could be attached to the
wheelchair to alert her when she is too near to an object. Are you aware of
such a thing?
