InactiveUS6061671AImprove reliabilityDifficult to recoverFranking apparatusStacking articlesData fileComputer science
System and method for securely backing up and reliably retrieving vault data in a metering system that includes a host processor operatively coupled to a vault. Whenever a transaction is completed by the vault, the vault cryptographically signs the vault data, including ascending register, descending register and piece count and sends the cryptographically signed vault data to the host processor where it is stored in a data file assigned to the vault. Each storage of the cryptographically signed vault data is indexed to create a historical log of vault transactions. If the vault is lost or damaged so that vault data cannot be retrieved from the vault, the cryptographically signed vault data is retrieved from the host processor data file and verified.

Quantization-Based Data Embedding in Mapped Data
InactiveUS20110044494A1Reduce errorsReduce the impactSpeech analysisCharacter and pattern recognitionAlgorithmDistortion
Novel methods and systems for quantization based data embedding and reading in host signals, such as image, audio and video signals. To embed auxiliary data in a host signal, an embedder maps the host signal from a first domain into a mapped signal in a second domain. The embedder performs quantization based embedding of auxiliary data into the host signal using quantizers. The quantizers are adapted such that the relationship between corresponding quantizers in the first and second domains satisfies a predetermined constraint. The mapping improves the robustness of the data embedding method by increasing the chances that the embedded data can be recovered by an auxiliary data reader after modifications. A related embedding method projects the mapped signal unto a vector, and specifically, a pseudorandom vector. It performs quantization based embedding on the projected signal. The use of this projection provides added robustness of the embedded data to noise and other forms of distortion.

Systems and methods for portfolio construction, indexing and risk management based on non-normal parametric measures of drawdown risk
InactiveUS20150206244A1Cutting can not be obtainedImprove performanceFinanceEnhanced indexingIndex score
A system, method and computer program for processing financial data in order to calculate and use new non-normal parametric measures of drawdown risk is disclosed, as well as a new set of portfolios construction techniques where the weights assigned to each single constituent asset are derived from this new measures. Risk measures based on drawdowns haven't received the extensive attention and use devoted to other common risk measures, due to the lack of an analytical understanding regarding how the drawdowns of a portfolio are related to those of its constituents. The present invention propose a solution to fill that gap, by developing: a new drawdown risk budgeting framework useful for portfolio allocation based on the drawdown contribution (marginal, total) to portfolio drawdown risk and drawdown correlation of its constituents; 4 different risk-based portfolio construction techniques useful for passive, enhanced-indexing and active portfolio management.

The present invention provided a method for salting-out extraction of acetone and butanol from a fermentation broth, characterized in that one type, or two or more types of salts and one type, or two or more types of extractants are added to an acetone-butanol-ethanol (ABE) fermentation broth, in which the salt saturation achieves 10%˜100%; and the volume ratio of the fermentation broth containing salts to the extractants is 1:0.1˜1:5. The mixture is allowed to stand until phase separation is formed. The top phase is a solvent phase or extraction phase enriched with acetone and butanol whereas the bottom phase is a salt-enriched phase or raffinate phase. This method involves many advantages, such as the simplified operation procedure, accelerated separation process and low separation cost, and therefore becomes a promising method of separating acetone and butanol in industrial application.
