Abstract
Methods, systems, computer program products, apparatus and circuits are configured to detect fallen containers upstream or proximate an intake zone suitable for automated evaluation apparatus using different sensors, including at least one lower sensor and at least one upper sensor which is positioned to project an optical signal at a height corresponding to a top portion of an upright container to thereby allow an increased reliability in detection of different orientations and positions of fallen containers. An optional second lower sensor may be used which is longitudinally spaced apart from the first lower sensor and the lower sensors can transmit optical signals across the container travel path that do not intersect.
