  • Patent number: 11753784
    Abstract: A material collection system includes a conduit, a vacuum generator coupled to the conduit, an engine powering the vacuum generator, and a container mounted to a chassis of a vehicle. The vacuum generator generates airflow for drawing material into a material inlet of the conduit. The container receives collected material from the conduit. The material collection container can receive collected material from the conduit. The control system can include a load sensor and a controller in electrical communication with the load sensor. The load sensor can detect a load applied by the collected material received in the material collection container and transmit an output signal indicating the load applied by the collected material. The controller can determine a weight of the collected material received in the material collection container based on the output signal and determine an aggregate weight of the vehicle using the determined weight of the collected material.

  • Patent number: 5622320
    Abstract: A foliage compactor includes an impeller assembly supported on a frame and including an enclosure having an inlet and an outlet, and an impeller supported for rotation within the enclosure to produce suction at the inlet and positive pressure at the outlet. An elongated hose is connected to the inlet so that foliage is drawn into the impeller assembly through the hose. A cyclone separator is supported on the frame beside the impeller assembly, and presents an upper inlet connected to the outlet of the impeller assembly so that air and foliage under positive pressure are introduced into the cyclone separator by the impeller assembly. The cyclone separator includes an outlet disposed lower than the inlet, and an exhaust vent located higher than the outlet for exhausting air from the housing.
