Abstract: An object detector reads distance measurement information and determines any presence of at least a portion of an object within a target area between the object detector and a background surface. The determination of the presence is based on distance measurement information. The distance measurement information is compared against a lower distance threshold and an upper distance threshold, where the lower distance threshold represents a distance between the object detector and the background surface, less a subtracted margin; and the upper distance threshold representing a distance between the object detector and a point beyond a distance of the background surface by an added margin. Satisfaction of either distance threshold is indicative of the presence of at least a portion of the object within the target area.

Abstract: In an optical sensing system, illumination light is selectively emitted by an illumination system at a selected wavelength from among a set of available wavelengths including a first wavelength, and a second wavelength that is different from the first wavelength, to illuminate a target area. The portion of the emitted light that is reflected from the target area is received by a photosensor that is sensitive in a range that includes the first wavelength and the second wavelength. A preferred at least one wavelength of the selective light emission is autonomously selected from among the first wavelength and the second wavelength based on assessed comparative performance of the photosensor in conjunction with the emitted light of the first wavelength and of the second wavelength in currently prevailing conditions.
