20140060701 | MULTI-AXIS CONTROLLED SELF-CLIMBING TREE TRIMMER - A multi-axis controlled self-climbing tree trimmer used for shaping and severing peripheral growth from a tree is provided herein. The trimmer typically includes a structural segment hinged together to form a rigid chassis that surrounds a tree trunk climbing segment and a trimming portion. The climbing portion is retained within the structural segment in the form of a number of inward-extending carriages containing one or more rollers for gripping the tree trunk during climbing, and the trimming portion may include a rotatable split ring gear containing centrifugally rotating trimming blade members and/or a cutting tool on a positionable arm. When rotated, the blade members unlatch and pivot, into the trunk of the tree to effect controlled trimming. The system may utilize a multi-axis control system that uses linear interpolation, circular interpolation and coordination of all axes to enable the trimmer to follow an XYZ contour selected by a user. | 03-06-2014 |

20140134904 | ARTICLES INCLUDING FRIMS AND METHODS OF USING THEM - Certain embodiments described herein are directed to articles that provide less sag. In some examples, the articles can include a fiber reinforced thermoplastic polymer core layer comprising reinforcing fibers and a thermoplastic polymer, and a frim disposed on the fiber reinforced polymer core layer. In certain examples, the frim comprises a film coupled to a scrim comprising an effective basis weight to prevent substantial sag of the article, e.g., during a forming operation. | 05-15-2014 |
20140162020 | ARTICLES INCLUDING UNTWISTED FIBERS AND METHODS OF USING THEM - Certain embodiments described herein are directed to composite materials comprising untwisted fibers. In some embodiments, the article can include a core layer comprising a thermoplastic polymer and reinforcing fibers. In other embodiments, untwisted fibers can be disposed on the core layer. In certain examples, the article is effective to provide a Class A finish when painted. | 06-12-2014 |

20130101822 | DEEP DRAW COMPOSITES AND METHODS OF USING THEM - Certain embodiments described herein are directed to composite materials effective for use in deep draw processes. In some examples, the composites can be used to provide vehicle panels such as, for example, vehicle underbody panels. In some configurations, the composite comprises a fiber reinforced polymer core and a skin material disposed on at least some portion of the fiber reinforced polymer core, in which the skin material comprises a basis weight of at least 65 g/m2 and an elongation at break of at least 20%. | 04-25-2013 |

20150222876 | BREAST SURGERY GUIDANCE BASED ON BREAST MR IMAGES AND RADIOACTIVE MARKERS - A system and method are provided for guiding surgery using MR images and radioactive markers. The method comprises reconstructing the surface of an anatomical structure and a gamma probe orientated to optimize a radioactivity reading from a radioactive seed placed at a target location in the anatomic structure for each of one or more positions of the gamma probe. The position and orientation of the gamma probe is detected in each reconstructed surface to estimate a position of the radioactive seed relative to the reconstructed surface. | 08-06-2015 |
