| 20090000698 | Suspendable tree cutter having an adjustable orientation pivot - Disclosed is a method and apparatus for cutting a tree using a helicopter and a tree cutter suspended from the helicopter. The tree cutter includes a frame which is selectively orientable about a horizontal axis of rotation by an elongate member extending perpendicular to the horizontal axis. A support line from the helicopter is mounted to the elongate member. The support line may be slid to a plurality of locations along the elongate member. Each of the plurality of locations corresponds to a unique orientation of the frame. A pair of gripping arms extend from the frame. A saw is pivotally mounted to the frame so as to cut a tree secured in the gripping arms. The method includes selectively orienting and suspending the cutting apparatus proximate to a tree to be cut, gripping the tree with the gripping arms and cutting the tree with the saw. | 01-01-2009 |

| 20100062287 | METHOD OF POLISHING AMORPHOUS/CRYSTALLINE GLASS TO ACHIEVE A LOW RQ & WQ - A method of polishing to reduce surface roughness of at least one surface of a glass ceramic substrate that includes an amorphous glass portion and a crystalline portion. The method comprises at least one step of polishing the surface using a polishing pad and an abrasive polishing slurry. The polishing slurry comprises a first concentration of Ceria particulates and a second concentration of Silica particulates. The amorphous glass portion and the crystalline portion of the at least one surface are polished substantially equally. | 03-11-2010 |
| 20120045969 | POLISHING AMORPHOUS/CRYSTALLINE GLASS - An apparatus and associated method for polishing a workpiece with a polishing slurry having ceria particulates and silica particulates. | 02-23-2012 |

| 20090067668 | VIDEO PROCESSING SYSTEM AND METHOD - A method of calculating a transform matrix for transforming points in a model of an object to an image of the object captured by a camera. The camera produces a two dimensional view of the object, the object having a plane, which includes a plurality of lines defining features on the plane of the object. The method comprises identifying a plurality of triplets of points on the lines of the object in the image from the camera, each of the triplets of points providing three or more non co-linear points on the lines of the object. The method includes identifying a sample triplet of points in the model, for each of the identified plurality of triplets of points, calculating a transform matrix which will transform the sample triplet from the model onto the identified triplet of points from the camera image, for each of the identified transform matrices, calculating a transform matrix for transforming a plurality of points on the lines of the object from the model to the image, calculating a comparison metric between the points transformed from the lines of the plane of the object in the model and corresponding points in the image view of the object, and identifying the transform matrix which produces the best comparison metric. The identified transform matrix can therefore be used to transform points on the model into the image produced by the camera, or points in the image onto the model. | 03-12-2009 |
| 20100246887 | METHOD AND APPARATUS FOR OBJECT TRACKING - There is described an apparatus and method for tracking objects in video. In particular, there is described a method and apparatus that improves the realism of the object in the captured scene. This improvement is effected by identifying a first and last frame in a video and subjecting the detected path of the object to a correcting function which improves the output positional data. | 09-30-2010 |

| 20090310861 | IMAGE PROCESSING - An image processing method includes partitioning an image under test to form a plurality of contiguous image segments having similar image properties, deriving feature data from a subset including one or more of the image segments, and comparing the feature data from the subset of image segments with feature data derived from respective image segments of one or more other images so as to detect a similarity between the image under test and the one or more other images. | 12-17-2009 |
