Abstract: A method, apparatus and system is provided for an entity to facilitate secure communication between a client and server even when they do not support the same set of protocols without violating the trust model which requires that only the client and server be privy to the contents of the communication. In an embodiment this is accomplished by embedding at the site of the proxy an application running inside a secure coprocessor which translates between the protocols that the client supports and those that the server understands. The invention is also useful for purposes such as adaptation of content at the site of the proxy without violating the trust model between the client and the proxy. In general, the scheme describes mechanisms to securely delegate to the infrastructure the ability to enforce an arbitrary trust model between a set of clients and servers participating in some computational task.

Abstract: The present invention related to an improved structure of an optically transparent element that can be used in optical scanners, supermarket scanners, lenses for eyeglasses, etc. The application of oxynitride PECVD films provide good hardness and optical transparency. Such films displaying these physical properties are extremely useful as a scratch resistant coatings in lenses and systems in which an article contacts a transparent surface, such as in scanners and in environments in which intermittent, environmental contact occurs such as in displays for computers and suchlike and in liquid crystal displays, touch displays and compact disks.

Abstract: Method of fabricating a semiconductor die with a microlens associated therewith. More particularly, a method for fabricating a vertical channel guide optical via through a silicon substrate wherein the optical via can contain lens elements, a discrete index gradient guiding pillar and other embodiments. Also disclosed are means for transferring, coupling and or focusing light from an electronic-optical device on the top of a semiconductor substrate through the substrate to a waveguiding medium below the substrate. The high alignment accuracies afforded by standard semiconductor fabrication processes are exploited so as to obviate the need for active alignment of the optical coupling or light guiding elements.

Abstract: A structure useful as a probe for testing electrical interconnections to integrated circuit devices and other electronic components having a substrate with a bond wire elongated electrical conductor extending away from the surface of the substrate. Each of the bond wire elongated electrical conductors has a first end affixed to the surface at an electrical contact location and a multitude of second ends projecting away from the surface. The first end and said second end of bond wire elongated electrical connector has a ball-shaped protuberance positioned thereon and there existsa in the system means for permitting each of the second ends to move about reference positions. The element which contains means for permitting each of the second ends to move about reference positions is a sheet of material having a plurality of through-holes therein through which the second ends project. There is a perforation in each said sheet in the vicinity of said openings.

Abstract: A method for forming an interconnect structure with nanocolumnar intermetal dielectric is described involving the construction of an interconnect structure using a solid dielectric, and introducing a regular array of vertically aligned nanoscale pores through stencil formation and etching to form a hole array and subsequently pinching off the tops of the hole array with a cap dielectric.

Abstract: In a virtual machine environment, a method and apparatus for the use of multiple heaps to retain persistent data and transient data wherein the multiple heaps enables a single virtual machine to be easily resettable, thus avoiding the need to terminate and start a new Virtual Machine as well as enabling a single virtual machine to retain data and objects across multiple applications, thus avoiding the computing resource overhead of relinking, reloading, reverifying, and recompiling classes. The memory hierarchy includes a System Heap, a Middleware Heap and a Transient Heap. The use of three heaps enables garbage collection to be selectively targeted to one heap at a time in between applications, thus avoiding this overhead during the life of an application.

Abstract: In the invention, it becomes possible to extract all clock information data processing data by simultaneously comparing first, second and third voltage levels to each data bit in clocked time increments wherein the magnitude of the increments is such that each binary data bit is in two of the three voltage levels and all data bits change each clock cycle, so that reconstructed signals of the binary information only may then be assembled based on a signal amplitude that is greater than a low threshold value that is less than the transition between the first and the second of the voltage levels and is less than a high threshold that is greater than the transition between the second and the third voltage levels. The reconstructed data signals are further shaped to be precise in timing, free of skewing and within the system clock.

Abstract: We present a communication system which enables two or more parties to secretly communicate through an existing digital channel which has a primary function other than this secret communication. A first party receives a series of cover data sets, hides a certain amount of auxiliary data in the cover data sets, and then relays these cover data sets containing hidden data to a second party, aware of the hidden data. This second party may then extract the hidden data and either restore it to its original state (the state it was in before the first party received it) and send it along to its original intended destination, or may just simply extract the hidden auxiliary data. There exist a plethora of techniques for hiding auxiliary data in cover data, and any of these can be used for the hiding phase of the system. For example, in a JPEG cover data set, a Huffman table may be modified in such a way as to have no impact on the observable nature of the image, and several such schemes are presented here.

Abstract: A two loop heat conversion system for high heat density planar devices in which high density heat in an area adjacent to a surface is transferred into a liquid cooling medium closed loop in a radiated heat to liquid heat transfer component positioned in contact with the surface that is connected, to a liquid to gas medium, heat exchanger in a first loop and a gas medium second loop is arranged to carry away all radiated heat from the assembly and all heat extracted from the liquid in the liquid to gas heat exchanger and exhaust it to the ambient. The radiated heat transfer component of the invention provides a transition in manufacturing that is practiced employing the planar type tools in fabrication which usually can neither be practiced manually or observed without substantial magnification.

Abstract: The invention is a selectable function that permits the address portion of data words to be separated from the storable content portion and that address portion to be used for different purposes without disturbing the stored contents in the memory array. The invention may be viewed as a command capability that permits analysis of signals for errors in such items as addresses, impedance calibration, timing, and component drift that develop in and between regions of an overall memory array. Techniques are advanced involving data responsive selectable array circuitry modification for such operations as address correctness verification, machine timing and component drift correction purposes. The principles are illustrated with memory systems built of Synchronous Dynamic Random Access Memory with Double Data Rate (SDRAM-DDR) elements.

Abstract: The invention enables the surveillance of computer-like devices while they are connected to a communications network. This latter includes a Network Surveillance Server (NSS). Upon joining said communications network, a device is first required to log-in to NSS. After which, NSS polls it while connected on the network so that an alarm can be issued, from NSS, to a central surveillance unit, if the device fails responding to polling. Hence, prior to leaving the communications network, the computer-like device is also required to log-out to NSS. Thus, as long as it is connected to the communications network, the computer-like device is watched.
