Abstract: Embodiments of the present disclosure relate to an object detection system that comprises at least one laser component. The at least one laser component is configured to generate an augmented light signal with a fan shape in a first plane. The at least one laser component is also configured to receive and detect a reflected light signal when an object is within a predetermined region of interest of the augmented light signal. In some embodiments of the present disclosure, the at least one laser component is configured to receive a reflected light signal from small objects than may be detected by other known object detection systems.

Abstract: The present disclosure describes a vacuum-excavation apparatus that is connectible to a vehicle. The vacuum-excavation apparatus comprises a vacuum tube with an input end; a vacuum assembly for generating a suction force at the input end and drawing a stream of fluidized debris-material into the vacuum tube. The apparatus also includes a boom assembly for supporting the vacuum tube and a tank for receiving the stream of fluidized debris-material from the vacuum tube. The tank provides a boom mount for pivotally connecting the boom assembly and for providing fluid communication between the vacuum tube and the tank. The apparatus also includes an evacuation tube for providing fluid communication between the tank and the vacuum assembly and for distributing at least a portion of stress-loads that are generated by the boom assembly.
