| 20090317705 | FUEL CELL INTERCONNECT STRUCTURES, AND RELATED DEVICES AND PROCESSES - A method for the formation of a diffusion barrier layer on a surface of at least one fuel cell interconnect structure is described. The interconnect structure is usually formed from ferritic stainless steel, and includes chromium. The method includes the step of coating an austenite phase-stabilizer on the interconnect surface, and then heating the coated surface.

| 20080231926 | Systems and Methods for Updating Dynamic Three-Dimensional Displays with User Input - A dynamic three-dimensional image can be modified in response to poses or gestures, such as hand gestures, from a user. In one implementation, the gestures are made by a user who selects objects in the three-dimensional image. The gestures can include indications such as pointing at a displayed object, for example, or placing a hand into the volume of space occupied by the three-dimensional image to grab one or more of the displayed objects. In response to the gestures, the three-dimensional display is partially or completely redrawn, for example by an alteration or repositioning of the selected objects. In one implementation, a system simulates the dragging of a displayed three-dimensional object by a user who grabs and moves that object. | 09-25-2008 |

| 20080252952 | Method and Apparatus for Recording One-Step, Full-Color, Full-Parallax, Holographic Stereograms - The present invention concerns methods and devices for creating and printing variable size and variable resolution holographic stereograms and holographic optical elements using computer rendered images of three-dimensional computer models or using computer processed images. The present invention is an apparatus and method for printing one-step, full-color, full-parallax holographic stereograms utilizing a reference beam-steering system that allows a reference beam to expose a holographic recording material from different angles. More particularly, a coherent beam is split into object and reference beams. The object beam passes through an object beam unit in which a rendered image is displayed, while the reference beam passes through the reference beam-steering system. The object and reference beams interfere with each other at an elemental hologram on a holographic recording material. A computer controls the exposure time and the movement of the recording material and may also render the images displayed in the object beam unit. In addition, the computer may also store the images before they are displayed in the object beam unit. Also, the present invention may also utilize a voxel-control lens placed in the path of the object beam and in close proximity to the holographic recording material to control the resolution of a holographic stereogram. In addition, the present invention may also utilize interchangable band-limited diffusers and reference-beam masking plates. Furthermore, the present invention incorporates viewing zone techniques to the rendering process for one-step, holographic stereograms to produce animated, one-step, holographic stereograms. | 10-16-2008 |
