An automated canopy positioning system for providing solar protection is
disclosed. The automated canopy positioning system orients the canopy of
the umbrella in relation to the sun so that a shade at a predetermined
location is provided thereunder. The system has a canopy for providing
shade in response to light impacting the upper surface, a first
photodetector for detecting the amount of light in the shaded area and
for generating a photocurrent in response to the light incident thereon,
a control circuit for receiving the photocurrent and for generating a
control signal in dependence thereon, and a positioning mechanism coupled
with the canopy for spatially orienting the canopy in response to the
control signal.
