Abstract: A method is provided for adding intended meaning to digital signatures. A message, being base content, is received to be signed. Assertions, ontologies, and description of a reasoner are adjoined to the message. Ontologies are a formal specification of vocabulary and rules used to state the assertions. The reasoner validates the assertions against the corresponding ontologies. A compound message is formed including the message, the assertions, the ontologies, and the reasoner. The compound message is signed using a cryptographic digital signature, where the assertions indicate an intended meaning of the digital signature. During verification of semantic signatures, a digital signature is received for a compound message, where the compound message includes assertions, ontologies, and reasoner. The digital signature is verified, and the compound message structure is checked for semantic signature conformance.

Abstract: A method for writing in a memory system that includes receiving an address corresponding to a memory location in a memory, receiving a desired content to be written, encoding the desired content into a symbol, and writing the symbol to the memory location using an iterative write process of at least one write and one read to the memory location. The iterative write process includes determining if the symbol was successfully written to the memory location and exiting the iterative write process in response to the symbol being successfully written to the memory location. The iterative write process also includes determining if a halt condition has been met and exiting the iterative write process if the halt condition has been met. Once the iterative write process has been exited, the memory location may be identified as a candidate for being written with a special symbol.

Abstract: A method and computer program product for code coverage utilizing efficient dynamic mutation of logic (EDML) are provided. A source code is read, and instrumentation points are located. Self Modifying Code (SMC) is inserted at the instrumentation points producing instrumented code. Additional functions are inserted in the source code to enable read and/or reset of code coverage statistics. The instrumented code is compiled, and executables are run for a period of time during which zero or more instrumentation points are executed. In response to executing instrumentation points, instructions are executed to record execution of the instrumented code. Instructions of the instrumented code overwrite themselves at certain points so that a next execution of the instrumentation points skips over the instrumented code at the certain points. Code coverage statistics are gathered and recorded. The code coverage statistics are reset to begin another period of time for gathering code coverage statistics.

Abstract: A method of forming a patterned functional layer on a substrate using a poly(hydroxyethyl methacrylate) lift-off layer is described. The method can be used with substrates that would not tolerate the organic solvents required for processing of known poly(methyl methacrylate) lift-off layers. When used in combination with known nanoimprint lithography and step-and-flash imprint lithography techniques, the method can be used to generate patterned functional structures with dimensions as small as five nanometers.

Abstract: A constant velocity joint assembly includes an outer joint member and an inner joint member. A first shaft is coupled to the inner joint member for articulated movement with the inner joint member relative to the outer joint member. A boot is coupled to the first shaft and the outer joint member to seal the constant velocity joint assembly. An insert is secured to and supported within the boot adjacent to and in abutting engagement with an axial end of the outer joint member. The insert limits movement of the first shaft to within a pre-determined range of articulation to prevent disengagement and/or disassembly of the inner joint member relative to the outer joint member.
