Abstract

Systems and methods to detect and warn proximate entities of interest are described herein. An example detection system includes a light source attachable to a forktruck, where the light source projects an illuminated warning field on a floor on which the forktruck is to traverse. The light source projects the illuminated warning field at a distance from a front end of the forktruck. The light source is separate from a headlight of the forktruck.
