Abstract: A multi-axis imaging system comprises an imaging gantry with an imaging axis extending through a bore of the imaging gantry, a support column that supports the imaging gantry on one side of the gantry in a cantilevered manner, a base that supports the imaging gantry and the support column, a first drive mechanism that translates the gantry in a vertical direction relative to the support column and the base, a second drive mechanism that rotates the gantry with respect to the support column between a first orientation where the imaging axis of the imaging gantry extends in a vertical direction parallel to the support column and a second orientation where the imaging axis of the gantry extends in a horizontal direction parallel with the base, and a third drive mechanism that translates the support column and the gantry in a horizontal direction along the base. The first drive mechanism comprises a non-backdrivable drive system including a motor geared into a lead screw that extends along a length of the support column. A carriage connected with the gantry has a nut fixed thereto that engages with the lead screw such that a rotation of the lead screw drives a translation of the carriage and the gantry in a vertical direction relative to the support column, wherein the lead screw and the nut are free from backdriving under load.

Abstract: A redundant tracking system comprising multiple redundant tracking sub-systems, enabling seamless transitions between such tracking sub-systems, provides a solution to this problem by merging multiple tracking approaches into a single tracking system. This system is able to combine tracking objects with six degrees of freedom (6DoF) and 3DoF through combining and transitioning between multiple tracking systems based on the availability of tracking indicia tracked by the tracking systems. Thus, as the indicia tracked by any one tracking system becomes unavailable, the redundant tracking system seamlessly switches between tracking in 6DoF and 3DoF thereby providing the user with an uninterrupted experience.

Abstract: A method for quickly cutting rigid polyurethane foam laminate, especially metal faced laminate, while the laminate is continuously transported on a conveyor, consists of moving circular saws, arranged in fixed disposition alternately above and below the laminate, towards and away from the laminate in a line perpendicular to the laminate. The saw blades collectively extend across the width of the laminate. Alternatively the blades are moved with a gyratory motion to increase the effective cutting width of each blade enabling the blade diameter to be reduced. 
     Saws 11 and 12 are two of three saws extending across the width of laminate 14 supported on a frame 15 mounted in guides 16 on a carriage 17 movable in synchronism with advancing laminate 14. The saw blades 11' and 12' are moved alternately into cutting engagement with the laminate by displacement of frame 15 relatively to carriage 17.

Abstract: Hitherto the commercial production of a gear crimped polyester yarn has not proved practicable due to extremely low bulk in the yarn and inadequate yarn mechanical properties. There is now provided a drawn gear-crimped polyester yarn with latent bulk the amount and nature of the bulk being such that the yarn has an initial crimp as defined of at least 1.5%, preferably of above 2%, and a mechanical crimp stability as defined of above 0%. The crimped polyester yarn may be produced by heating a drawable polyesteryarn (9) having a birefringence in the range 32 x 10-' to 125 x 10-' inclusive, preferably 35 x 10_ 3  to 125 x 10 -3  inclusive, crimping the yarn by guiding it between the intermeshing teeth of a set of toothed wheels (11,19) such that the yarn is caused to follow a sharply zig-zag path, the toothed wheels being rotated at a sufficient speed such that the yarn is drawn by the tension so imparted to the yarn by the toothed wheels and subsequently forwarding the crimped yarn from the toothed wheels under a controlled tension within the range 0.15 to 0.50 g per decitex inclusive based on the decitex of the drawn polyester yarn.
