Abstract: A digital file is associated with a header in which identification data for a physical key is stored. The digital file content is encrypted, and may not be decrypted by a receiving computer unless a removable physical key that can be associated with the receiving computer includes identification data which matches the identification data stored in the file header. The digital content encrypted in the file may be compressed, and the header may also be encrypted. When the header is encrypted, the receiving computer may decrypt only the header unless the identification data of the header matches the identification data for a removable physical key. Improved security and reduction of pirating of the digital content are therefore provided.

Abstract: A characteristic forecasting system is disclosed. The characteristic forecasting system may have a memory module and a processor. The memory module may store instructions, that, when executed, enable the processor to generate forecast data for a target item based on historical data related to the target item, the forecast data representing a forecast for characteristics of the target item. The processor may also be enabled to analyze a subset of the historical data within an observation window to determine whether the forecast data should be updated with new forecast data and generate the new forecast data for the target item responsive to a determination that the forecast data should be updated with the new forecast data.

Abstract: A first network signal is received indicating a device identifier in response to a transaction involving an electronic device uniquely associated with the device identifier. An entity identifier specific to an entity associated with the transaction is determined. In response to an initialization event of the electronic device, a second network signal from the electronic device is received that identifies the electronic device. In response to the second network signal, a configuration is communicated to the electronic device that is specific to the entity associated with the transaction.

Abstract: A digital file is associated with a security attribute in which identification data for a physical key is stored. The digital file content is encrypted, and may not be decrypted by a receiving computer unless a removable physical key that can be associated with the receiving computer includes identification data which matches the identification data stored in the file's security attribute. The digital content encrypted in the file may be compressed, and a portion of the security attribute may also be encrypted. When a portion of the security attribute is encrypted, the receiving computer may decrypt only the encrypted portion of the security attribute unless the identification data of the security attribute matches the identification data of a physical key physically or wirelessly coupled to the receiving computer. Improved security and reduction of pirating of the digital content are therefore provided.

Abstract: Disclosed herein is an improved architecture for regular expression pattern matching. Improvements to pattern matching deterministic finite automatons (DFAs) that are described by the inventors include a pipelining strategy that pushes state-dependent feedback to a final pipeline stage to thereby enhance parallelism and throughput, augmented state transitions that track whether a transition is indicative of a pattern match occurring thereby reducing the number of necessary states for the DFA, augmented state transition that track whether a transition is indicative of a restart to the matching process, compression of the DFA's transition table, alphabet encoding for input symbols to equivalence class identifiers, the use of an indirection table to allow for optimized transition table memory, and enhanced scalability to facilitate the ability of the improved DFA to process multiple input symbols per cycle.

Abstract: Aspects of this disclosure describe a multi-pass printer having a photoreceptor device mounted on an axis, a developer that is arranged adjacent to the photoreceptor device and is movable between a first position and a second position, and a camming mechanism mounted on the axis that acts upon the developer to urge the developer between the first and second positions. The camming mechanism can further include a camming disc that is mounted to rotate about the axis. The camming disc can also have an outer periphery edge having a first portion defined by a first radius and a second portion defined by a second radius. The camming mechanism can also have a developer roll spacing cam having an effective radius that maintains a spacing between the developer and the photoreceptor device.

Abstract: A process for transitioning between Ziegler Natta (Z/N) polymerization catalysts and Second Polymerization catalysts in a polymerization system which includes at least two polymerization reactors. During the transition, the Z/N catalyst is used in the “downstream” reactor, thereby providing a flow of polymer to finishing operations. This eliminates the need for lengthy shutdowns of finishing equipment and thereby improves the efficiency of the plant operations.

Abstract: Methods and systems for performing parallel membership queries to Bloom filters for Longest Prefix Matching, where address prefix memberships are determined in sets of prefixes sorted by prefix length. Hash tables corresponding to each prefix length are probed from the longest to the shortest match in the vector, terminating when a match is found or all of the lengths are searched. The performance, as determined by the number of dependent memory accesses per lookup, is held constant for longer address lengths or additional unique address prefix lengths in the forwarding table given that memory resources scale linearly with the number of prefixes in the forwarding table. For less than 2 Mb of embedded RAM and a commodity SRAM, the present technique achieves average performance of one hash probe per lookup and a worst case of two hash probes and one array access per lookup.
