Abstract: The present invention is a method of surface preparation and imaging for integrated circuits. First, a substrate is selected and an opening is cut in the substrate of a sufficient size to fit an integrated circuit to be analyzed. A second substrate is then selected. An adhesive film is applied to the top surface of the first substrate, the adhesive film having adhesive on both sides and covering the opening on the first substrate. An integrated circuit is then inserted into the opening and attached to the bottom side of the adhesive film. Next, the first substrate and integrated circuit are bonded to the second substrate using the adhesive film. The bottom side of the first substrate and the integrated circuit are then thinned until the substrate wafer of the integrated circuit is completely removed. The bottom side of the first substrate and integrated circuit is then thinned to a user-definable level. A handle wafer is then attached to the bottom side of the first substrate.

Abstract: The present invention facilitates the specification and distribution of templated content materials by a content provider over an information exchange network such as the Internet. The present invention incorporates a system for managing inventories of graphical elements and their relationships to pre-defined page templates. A database capable of keeping track of users and their corresponding access privileges within the system is employed to monitor user activity. Ultimately, through the use of a software component delivered over the Internet for use within standard web browsers, end-users are able to populate templates under the constraints imposed by the rules of the manufacturers at the time of template design. These population elements which “fill in the blanks” of the pre-defined templates may be either of type IMAGE or TEXT.

Abstract: A holographic optical element (HOE) device is mounted in a receiver unit, such as a wireless optical telecommunication system receiver. The HOE device includes a developed emulsion material having an interference pattern recorded thereon, sandwiched between a pair of elements, such as a pair of clear glass plates. In operation, the HOE device uses the recorded interference pattern to diffract incident light rays towards an optical processing unit of the system receiver. The optical processing unit includes a photodetector that detects the diffracted light rays. The system receiver can include various other components and/or can have various configurations. In one configuration, a plurality of mirrors is used to control the direction of the light rays coming from the HOE device, and a collimating optical assembly collimates these light rays. A beam splitting optical assembly can be used to split the light rays into a tracking channel and a communication channel.

Abstract: A method and apparatus for measuring colorimetric, gloss and registration data on a substrate exiting a printing machine. A detector using a series of red, green, and blue filters collects image data and maps the collected data to absolute color coordinates. The apparatus is factory calibrated to the specific colorants used in the printing machine. Gloss measurements are made using the same apparatus. Registration data between the various color separations is also obtained and feedback delivered to the various imaging modules. The detector allows on the fly data to be obtained and machine specific corrections to be made.
