Abstract: For occlusion handing in lightfield rendering, layered lightfields are created. Rather than use one lightfield for one camera position and orientation, multiple lightfields representing different depths or surfaces at different depths relative to that camera position and orientation are created. By using layered lightfields for the various camera positions and orientations, the camera may be located within the convex hull or scanned object. The depths of the layers are used to select the lightfields for a given camera position and location.

Abstract: The invention relates to a thermo-forming packaging machine comprising a product feeder for feeding a product to a loading stretch of the packaging machine, and a film web having trays formed therein wherein the trays are configured to receive a product. The product feeder may be arranged at least partially parallel to the loading stretch of the packaging machine. The thermo-forming packaging machine also includes a side panel disposed along the loading stretch that is formed such that it also forms part of the product feeder.

Abstract: Robotic navigation is provided in nuclear probe imaging. Adaptive reconstruction is provided. A measure of quality of the reconstruction is used as a feedback to determine when sufficient sampling has occurred. For example, once a pre-determined number of separate lesions are indicated in the reconstruction, the quality of the reconstruction is considered sufficient.

Abstract: A method for rendering a deformable object. The method includes: obtaining a 3D volumetric voxel dataset of a region, such region having therein an object to be rendered; building a tree hierarchical structure for the obtained volumetric dataset, such tree structure blocks as the nodes of a primary tree hierarchy and bricks being those blocks stored as textures in a video memory; augmenting the primary tree hierarchical structure with maximum and minimum values of the data contained within a block; creating a neighborhood tree hierarchy having for each leaf block of the neighborhood tree hierarchy a reference to the neighboring leaf blocks in the neighborhood tree hierarchy as well as references to neighboring bricks in the neighborhood tree hierarchy; updating the information about minimum and maximum in the primary tree hierarchy by saving for each block the minimum and maximum of the neighboring blocks; and rendering the leaf blocks in visibility order.

Abstract: A hydraulic system for actuating a clutch and/or a variable speed drive unit of a belt-driven conical-pulley transmission of a vehicle, such as a commercial vehicle, and having a variable transmission ratio and a torque sensor. The hydraulic system includes at least one hydraulic energy source. A selector and check valve is provided for supplying additional components besides the torque sensor and is connected between the hydraulic energy source, the additional components, and the torque sensor in such a way that the torque sensor includes priority in being supplied with hydraulic medium.

Abstract: A positive-displacement pump having an eccentrically positioned internal ring gear and pinion within a pump housing. Pressurized operating fluid is provided by the pump to actuate an actuation piston of a clutch unit, such as a double clutch unit. The clutch unit is drivingly coupled with the pump for movement between engaged and disengaged positions. At least one throughbore is provided in the pump housing within which throughbore the clutch actuation piston is guided.

Abstract: A method for non-rigid multi-modal registration of digitized images includes providing a reference image and an alignment images acquired from different imaging modalities to a graphics processing unit (GPU), initializing a deformation field for registering said reference image and said alignment image, computing marginal and joint intensity histograms of the reference image and the alignment image as registered by said deformation field, computing gradients of the reference and registered alignment images and of their respective marginal and joint intensity histograms, smoothing said histograms and gradients using Gaussian filters, calculating a new deformation field using said smoothed gradients, and registering said alignment image to said reference image using said deformation field.

Abstract: A multiple clutch assembly for use in the power train of a motor vehicle between a prime mover and a change-speed transmission. A hub is coupled to a pumping device for an operating fluid. The pumping device is located radially outwardly of two coaxial, interfitted input shafts of the transmission. Each of the transmission shafts is associated with a discrete one of two clutches. The placing of the pump radially outwardly of the input shafts of the transmission contributes to simplicity and lower cost of the multiple clutch assembly.
