Abstract: Techniques are disclosed for window sharing with occlusion removal. In an embodiment, the techniques begin with a blank composition image, to which shared windows are added. For each window of a desktop from which at least one window is shared, traversing the windows from greatest z-depth to least z-depth, the window is processed based on whether it is shared and is occluded. Shared windows are copied to the composition image. Where a part of a shared window is occluded and cannot be retrieved, an indication of this occlusion is added to the composition image. When the windows have been processed, the composition image is encoded and sent to a client computer where it is displayed to produce the window sharing between computers.

Abstract: The illustrated invention defines an analytical chip comprising an optically transparent substrate such as glass or silicon that defines a fluid inlet port and at least one fluid carrying channel communicating with the inlet. At least one reaction chamber fluidly communicates with the channel and an air management chamber is in fluid communication with the reaction chamber to facilitate capillary flow of fluid into the reaction chamber.
