Abstract: According to one aspect, the subject matter described herein includes a method for secure content watermarking. The method includes generating a watermark that encodes information as a set of visual elements; receiving content that represents a graphical workspace to be displayed to a user; creating watermarked content by combining an image of the received content with at least one copy of the watermark sufficient to fill the area of the image; and displaying the watermarked content to the user via a display device having a display area. Should the user take a screenshot or take a picture of some or all of the watermarked content, the picture so acquired will contain watermark information that can be used to identify the session from which the picture or screenshot was taken.

Abstract: The present invention is directed to an interposer having an interposer substrate with an upper surface and a lower surface and at least one resilient contact element having an upper portion and a lower portion. The upper portion extends in a substantially vertical fashion above the upper surface of said interposer substrate, and the lower portion extends in a substantially vertical fashion below the lower surface of said interposer substrate. The upper and lower portions of the resilient contact element are substantially resilient in a direction parallel to the substrate.

Abstract: Optical switch packaging techniques and optical switch components are described. In one aspect, an optical switch component that includes a die mounted on an interposer is described. The die has an exposed array of mirrors that can be used as part of an optical switch. Typically, the interposer will also have a fiber array mount arranged to receive a fiber bundle and to position the fiber bundle appropriately over the array of mirrors. In some embodiments, an optical switch can be formed by putting together two mirror image interposer based optical switch components. When placing two interposer based optical switch components together, an alignment frame may be positioned between the interposers to help maintain a desired spacing between the respective arrays of mirrors. In some such embodiments, an inner housing is provided that encloses the dice, the fiber array mounts the alignment frame and portions of the interposers, but leaves connectors mounted on the interposers exposed.
