Abstract: A wheel slide detection system with at least one device, such as a camera, to capture an image of a wheel, and a processor to receive the captured image, identify the wheel, and to analyze the relative position of the wheel to determine whether or not the wheel is rotating. The system can detect rotation, non-rotation or partial rotation of the wheel. The camera(s) can be triggered by sensor-activation or microprocessor-activation. A visible or electronically encoded feature or marker on the wheel can be used as a reference for establishing wheel rotation. A processing algorithm can compare the location of the feature or marker on consecutive images to assess rotation of the wheel by determining an angle of rotation of the wheel.

Abstract: A wheel slide detection system including an image capture means to capture an image of a wheel and a processing means to receive said captured image, identify said wheel and analyse the relative position of said wheel to determine whether said wheel is rotating.

Abstract: A container for transporting bulk material including two side walls, two end walls, and a base; the side walls including a plurality of vertical reinforcing members spaced along the length of the side wall, wherein the side wall between at least one adjacent pair of the reinforcing members includes at least one internal ridge running therebetween.
