ABSTRACT:
Harmful effects of the sun are becoming more prominent than they have been in the past. Thus, appropriately shielding ourselves from the sun has become ever more important. Unfortunately, applying sunscreens to infants may not be preferable thus sunshade umbrellas have been developed that clamp onto a stroller and are user positionable to provide shade to the infant located thereunder. Unfortunately, as the stroller I moved with respect to the sun, the orientation of the umbrella must be varied in order to ensure the infant is in adequate shade. Not applicable to just stroller umbrellas, an automated position in system for an umbrella is thus disclosed. The automated positioning system orients the canopy of the umbrella in relation to the sun so that shade at a predetermine location is provided thereunder.
