  • Patent number: 8833280
    Abstract: In methods according to some embodiments of the present disclosure for interplanting a primary crop and an energy crop, the present disclosure includes methods for preparing a plantation site for planting the energy crop. Plantation sites according to the disclosure may include a primary crop planted in a first row and in a second row, the first row being separated by an intermediate row. The intermediate row is divided into a center portion and two side portions (a first side portion and a second side portion). Methods according to embodiments of the disclosure include the steps of lifting a soil and plantation debris mixture from the intermediate area, redepositing a soil component of the soil and plantation debris mixture primarily into the center portion, and redepositing a plantation debris component of the soil and plantation debris mixture primarily into at least one of the two side portions.

  • Publication number: 20140251499
    Abstract: At least one image device proximate a second conveyor is disposed a predetermined distance in front of chip heads. The at least one image device can image a log and capture the actual log position on a sharp chain before its being engaged by chip heads. A computing device is coupled to the at least one image device to receive data including the actual log position information. The computing device compares the actual log position to a preferred log position solution so as to check whether a log deviates from its expected position. If any position deviation exists, the computing device may send instructions to adjust the positions of the chip heads and saws to ensure that a log is correctly positioned relative to the chip heads and saws, whereby correcting log position errors and eliminating transport accuracy losses.

  • Publication number: 20140238546
    Abstract: Processing of a cant may include determining a rotational orientation about a longitudinal axis of the cant that optimizes a recovery from the cant from subsequent sawing operations. Such may include optimizing a width of a board that will be produced dependent on the particular rotational longitudinal orientation. Such may include determining a surface area of a board which would be produced, a thickness of a board that would be produced, and/or a volume of a board that would be produced. Such may include accounting for any premium associated with various width categories in which a board that would be produced would fit. Such may account for any premium associated with grade or quality of a board that would be produced. A corresponding signal may provide information to a human operator and/or automated machinery to orient the cant in an optimized orientation.

  • Patent number: 8801901
    Abstract: Embodiments of sized fluff pulp, or fluff pulp treated with a sizing agent, have desirable characteristics for one or more intended applications. The sized fluff pulp can be debonded or non-debonded. In several examples, the one or more desirable characteristics includes a reduction in its absorption characteristics (e.g., the pulp is less hydrophilic). Some characteristics improved by the sized fluff pulp include, but are not limited to, soak and drip capacity and wicking rate. In several examples, the sized fluff pulp are less hydrophilic but retain or exhibit other desirable characteristics for producing non-wovens, including low fiberization energy and fiberized knot percentage.

  • Patent number: 8775119
    Abstract: A system and method for identifying stands or portions thereof that are not growing as expected. In one embodiment, a computer system compares a measured leaf area index of a stand that is determined from remotely sensed data to an expected leaf area index. The computer system identifies stands or portions of stands where the measured leaf area index is greater than the expected leaf area index and/or stands or portions of stands where the measured leaf area index is less than the expected leaf area index. In one embodiment, the comparison is used to identify stands or portions thereof where silviculture treatments may be necessary.

  • Patent number: 8775081
    Abstract: A programmed computer or non-transitory computer readable storage media has instructions that are executable by a processor to identify LiDAR data points associated with items of vegetation or other objects. Each LiDAR data point is tested to determine if it lies within the value of a closed surface defined for higher LiDAR points. If so, the LiDAR point is grouped with the LiDAR points associated with a previously identified item of vegetation. If not, a new item of vegetation is identified.

  • Publication number: 20140185884
    Abstract: A programmed computer system estimates the age of trees from a number of remotely sensed images of an area of interest. Vegetation Index (V.I.) values are determined for pixel locations in the number of images. The V.I. values are analyzed to find a V.I. value that correlates with a known age of a tree. Once the date of the image that produced the V.I. value is known, the current age of the trees that correspond to the pixel location is determined.
