Abstract: There is provided a computer-implemented method for remotely pointing to a region of interest within a simulation environment, the process comprising the steps of: receiving coordinates of at least one point selected within a given image of at least a portion of the simulation environment, the given image being displayed on a display unit; identifying a region of interest within the simulation environment based on the received coordinates of the at least one point; and providing control signals to a projector to visually distinguish the region of interest within the simulation environment.

Abstract: The invention is directed to effective means for joining materials having dissimilar coefficients of thermal expansion, such as advanced ceramics with metallic compounds. Moreover, the present invention relates to furnace tubes and methods of fabricating a joint between two different materials, which is compositionally graded to provide a substantially graded coefficient of thermal expansion between the joint materials.

Abstract: A process for joining at least two substrates together comprises applying between the substrates a composition comprising a liquid pre-ceramic binder and at least one other component selected from a metal powder, a metal oxide powder and mixtures thereof, and pyrolysing the composition, to form a join between the two substrates, the join comprising a mixed metal oxide. The composition is capable of joining together a wide variety of substrates, without failure, after exposure to high temperature.

Abstract: The present invention relates to a method for reducing image instability in a virtual environment due to the transport delay of the image generator and other components of the system. A method is given for determining the error in the generated virtual environment and using this error for shifting the image on the display device thus providing a more accurate and more stable representation to the viewer.

Abstract: For displaying moving images on a head mounted, temporal modulation display device from a video source, without image break-up appearing in the observed image, an image shift device is provided for shifting each temporally separated component image within each display cycle of grey scale component images representing each frame of the video source. The display device is for use with head mounted displays in which an LCD or other FPD using temporal modulation is used to display video images without image break-up during head motion.

Abstract: For displaying moving images on a field sequential color display device from a simultaneous color image source, without color break-up appearing in the observed image, an image shift device is provided for shifting each color component image within each cycle of color component images representing each frame of the simultaneous color video image source. The display device is for use with head mounted displays in which an LCD or a CRT screen is used to display field sequential color images without color break-up during head motion.
