Abstract: An approach for fingerprinting large data objects at the wire speed has been disclosed. The techniques include Fresh/Shift pipelining, split Fresh, optimization, online channel sampling, and pipelined selection. The architecture can also be replicated to work in parallel for higher system throughput. Fingerprinting may provide an efficient mechanism for identifying duplication in a data stream, and deduplication based on the identified fingerprints may provide reduced storage costs, reduced network bandwidth consumption, reduced processing time and other benefits. In some embodiments, fingerprinting may be used to ensure or verify data integrity and may facilitate detection of corruption or tampering. An efficient manner of generating fingerprints (either via hardware, software, or a combination) may reduce a computation load and/or time required to generate fingerprints.

Abstract: A method, system and computer program is disclosed for reducing range and angular ambiguities in a target data matrix output from a real beam monopulse radar sensor within a single beam for use in terrain morphing applications employed by brownout take-off and landing aid systems. One or more range bins are calculated to selectively determine one or more range segments from one or more targets of interest. Range resolution enhancement processing is employed to the selectively determined one or more range segments to obtain a range of target scatter locations. A monopulse angle bin is estimated from the obtained range of target scatter locations and one or more control inputs. Elevation and azimuth angular binning is applied to the estimated monopulse angle bin to obtain a smaller coverage area among one or more possible target areas.

Abstract: An apparatus and method for accurate end-of-charge (EOC) detection in a battery charger is provided. An EOC circuit determines that a battery has been fully charged when two conditions are met. The first condition for EOC detection is that the battery has reached a predetermined voltage and, as a result, the battery charger has transitioned to a constant voltage phase of the charging process. The second condition for EOC detection is that the battery current has fallen below a predetermined, set level. When both of these conditions are met, EOC is detected. This bi-condition EOC detection scheme is capable of accurate EOC detection, i.e. determining when the battery is fully charged.

Abstract: Methods and systems for growing uniform oxide layers include an example method including growing a first layer of oxide on first and second facets of the substrate, with the first facet having a faster oxide growth rate. The oxide is removed from the first facet and a second oxide layer is grown on the first and second facets. Removing the oxide from the first facet includes shielding the second facet and exposing the substrate to a deoxidizing condition. The second facet is then exposed to receive the second oxide layer. Areas having differing oxide thicknesses are also grown by repeatedly growing oxide layers, selectively shielding areas, and removing oxide from exposed areas.

Abstract: Systems and methods for measuring thickness of an epitaxial layer grown on a silicon wafer. An oxide layer is generated on a side of the silicon wafer. One or more posts of oxide are created from the oxide layer by masking and removing unwanted oxide. An epitaxial layer is grown on the side of the silicon wafer over the one or more oxide posts. The epitaxial layer is removed in an area that includes at least the epitaxial layer grown on the one or more oxide posts. Then, the one or more oxide posts are removed. The thickness of the epitaxial layer is determined by measuring a distance along an axis between a surface of the silicon wafer where one of the one or more oxide posts previously attached and a top surface of the epitaxial layer, the axis being approximately perpendicular to the surface of the wafer.

Abstract: A method dramatically reduces the amount of data to be stored and transferred in a networked storage system. Preferably, the network storage system provides continued data protection through mirroring/replication, disk-to-disk backup, data archiving for future retrieval, and Information Lifecycle management (ILM). The idea is to leverage the parity computation that exists in RAID systems. By caching, transferring, and storing data parity or delta bytes of changes on a block as opposed to data block itself, substantial data reduction is possible without using sophisticated compression algorithms at the production side to minimize performance impacts upon production servers. Data can be computed using the parity/delta and previously existing data at mirror side, replication side, backup storage, or at retrieval time upon events such as failures or ILM operations.

Abstract: Featured is a data storage back-up system for replication, mirroring and/or backing-up data including one or more first and second data storage devices that embody iSCSI, FC or alike principals and that are operably coupled to each other preferably via a WAN. The first data storage device is configured and arranged so there are two writes of data, one write to a persistent storage device from which reads are done and another write to a SAPS device wherein the data is saved using log-structured file system (LSF) techniques. After saving data to the First storage device, the data logs in the SAPS device are communicated to the second data storage device whereat a de-staging process is conducted so as to de-stage the data logs and write the de-staged data to a persistent storage device in the second data storage device.
