Patent attributes
Bicycle safety exclusion zone systems capable of being attached to a bicycle, comprised of one or more projector-sensor devices and a processing unit. Each projector-sensor device is capable of detecting vehicles in proximity of the bicycle and of projecting at least a portion of a visual safety exclusion zone upon ground surrounding the bicycle. The processing unit is in communication with the one or more projector-sensor devices. When one of the projector-sensor devices detects a vehicle in proximity to the bicycle, the processing unit generates an alert detectable by a user of the bicycle, and the one or more projector-sensor devices change the visual appearance of the visual safety exclusion zone. In some embodiments, the change in the visual appearance of the safety exclusion zone comprises a change of color.
