  • System and method for bucking a stem
    Patent number: 9999987
    Abstract: Provided is a method for bucking a stem that utilizes the combination of moving sensor and a fixed sensor. The fixed sensor measures a location of a first end of the stem travelling on a conveyor to determine a travel distance the first end has moved past the fixed sensor. The movable sensor measures a location of a second end of the stem to determine a sensor distance between the fixed sensor and the movable sensor. The length of the stem is determined by adding the travel distance to the sensor distance.
