A results index is then acquired and the Hidden Web pages are downloaded from the results index. A plurality of potential query terms are then identified from the downloaded Hidden Web pages. The efficiency of each potential query term is then estimated and a next query term is selected from the plurality of potential query terms, wherein the next selected query term has the greatest efficiency. The next selected query term is then issued to the site-specific search interface using the next query term. The process is repeated until all or most of the Hidden Web pages are discovered. In one aspect of the invention, the efficiency of each potential query term is expressed as a ratio of number of new documents returned for the potential query term to the cost associated with issuing the potential query.

Steering assist system and steering assist method
ActiveUS20090194350A1Reduce impactReduce biasSteering initiationsDigital data processing detailsDriver/operatorEngineering
A steering assist system for applying a steering torque reduces the influence of a time-dependent steering control amount on an assist steering torque when a predetermined driving operation by a driver is detected. Thus, the influence of the time-dependent steering control amount on the applied steering torque, which increases when the period of time over which actual moving state deviates from the target moving state increases is reduced when the driver makes the predetermined driving operation. Thus, it is possible to avoid the problem where steering feel degrades because the steering torque increases over time.

Case management system using a medical event forecasting engine
InactiveUS20160328526A1Reduce biasEasy to discover episodic progressionMedical data miningEnsemble learningDynamic featureEngineering
A case management tool uses a novel event forecast engine. The engine leverages a flexible and extensible data structure that combines diverse formats of claims (e.g., both medical and pharmacy) and that highlights “episodes” rather than items. The engine also makes predictions with respect to “cohorts” groups, where cohorts are defined using both static and dynamic features, the latter being features that change their values based on observation periods. Multiple definitions of cohorts are implemented, and optimal cohort definitions are estimated. The engine uses rolling time window processing to extract dynamic features in the data sets, and then one or more machine learning algorithms are applied to the extracted data. Cohort-wise machine learning models preferably learn on dynamic features, which are then put together for final predictions. A validation step is applied when outcomes are later observed. Validation results update the cohort definitions as well as the model parameters.

High purity water, particularly that intended for the pharmaceutical or electronics industry, is analyzed for the presence of pyrogen or other impurities by causing the water to come into contact with a direct affinity sensor, which may be a surface plasmon resonance (SPR) device or other sensor relying on an evanescent wave phenomenon. A property of the surface-refractive index in the case of SPR-changes on the binding of impurity, thereby enabling impurity to be detected. The invention overcomes the cumbersome nature and batch-to-batch variability of the conventional in vivo tests as well as the in vitro Limulus Amoebocyte Lysate (LAL) assay and for the first time allows the continuous or real time monitoring of high purity water for pyrogen.
