Abstract: A pallet trolley includes: a frame having two ends, the frame defining a longitudinal axis; a handle assembly attached to the frame; a first wheel assembly attached to the frame at one end; and a second wheel assembly attached to the frame at the other end, the first and second wheel assemblies are oriented to allow the pallet trolley to roll in a direction other than parallel to the longitudinal axis of the frame. A method of moving a pallet includes: providing a pallet trolley having first and second wheel assemblies; locating the first and second wheel assemblies under a pallet; lowering the pallet onto the trolley; and moving the pallet on the trolley and a fork truck.

Abstract: A method of estimating position and orientation of a vehicle using image data is provided. The method includes capturing an image of a region external to the vehicle using a camera mounted to the vehicle, and identifying in the image a set of feature points of the region. The method further includes subsequently capturing another image of the region from a different orientation of the camera, and identifying in the image the same set of feature points. A pose estimation of the vehicle is generated based upon the identified set of feature points and corresponding to the region. Each of the steps are repeated at with respect to a different region at least once so as to generate at least one succeeding pose estimation of the vehicle. The pose estimations are then propagated over a time interval by chaining the pose estimation and each succeeding pose estimation one with another according to a sequence in which each was generated.

Abstract: There are provided novel oxygenated pentamethyldecalins and dehydro derivatives thereof which are lasting odorants of woody character and which are useful in the perfumery art.These novel compounds are prepared by oxidation of cis-thujopsene and cis-dihydrothujopsene which are readily available products of natural origin.
