Abstract: A data search and retrieval system that, in response to a search query, dynamically selects and applies a model of information to be returned to a user. The model may be selected based on the search query directly, or indirectly based on data returned by a search engine applying the query. For this purpose, the system may include an index of models, similar to a search index. Models may include expressions that may be descriptions of computations, equations, constraints or rules to define information to be returned. These elements of a selected model may be executed within to the search stack based on data identified in a search of web pages by executing the query or other dynamically obtained data. Execution of a model may lead to collecting new information, such as through further searching or performing computations, or may result in ordering or other formatting of data.

Abstract: A data search and retrieval system that, in response to a search query, applies a model to search results to generate information to be returned to a user. A user may modify the model via a set of controls displayed to the user. The modified model may then be applied to search results to generate information in compliance with the modified model. Modified models may be stored locally on a client system or stored in the search system and made available to other users so that the modified models can be applied to subsequent requests for information. The modified models and the results of a search may be stored on a client machine such that, as the model is modified, new information may be generated based on the original search, reducing communication bandwidth, which can improve the speed and cost of providing user interaction with data in a mobile environment.

Abstract: A data search and retrieval system that, in response to a search query, dynamically selects and applies a model of information to be returned to a user. The model may be selected based on the search query directly or indirectly based on data returned by a search engine applying the query. For this purpose, the system may include an index of models, similar to a search index. Models may be authored and contributed to the search and retrieval system by third parties, and an association between each such contributed model and characteristics of a search query, such as specific search query terms, may be stored in the index of models. A user of the search and retrieval system may provide feedback on a model that was used to generate information in response to the user's search query, and such feedback may be used to update the index of models.

Abstract: A wind turbine pitch control system is disclosed that provides a pulsed torque to the blade pitch actuator if continuous torque fails to adjust the blade pitch angle to a commanded pitch angle. This invention provides a cost-effective way to increase peak torque capability for existing wind turbines that have problems, under certain operating conditions, moving blades per the control command.

Abstract: A method of controlling a wind turbine that includes at least one rotor shaft and at least one blade operatively coupled to the rotor shaft includes measuring a first wind turbine operational condition that is representative of a blade deflection value and generating a first operational condition signal based on that first wind turbine operational condition. The wind turbine also includes a drive train including at least one rotor shaft and an electric generator. The method also includes measuring at least one second wind turbine operational condition and generating at least one second operational condition signal. The method further includes changing the blade deflection value by changing the second operational condition.

Abstract: A potential user query that can be subsequently received from a user is identified. An interface exposed by a data service is invoked, which includes providing the potential user query to the interface. Search results in response to the potential user query are received from the interface and maintained in a complex data set store. If a user query is subsequently received that maps to a normalized query that is the potential user query, then search results for the normalized query are obtained from the complex data set store and returned as the search results for the user query.

Abstract: Processes for isolating bitter compounds for use in food and beverage products entailing contacting a bitter compound composition with an adsorbent to adsorb bitter compounds from the bitter compound composition, desorbing the bitter compounds from the adsorbent to obtain a bitter compound isolate, and adding the bitter compound isolate to a food or beverage product to enhance the flavor thereof.

Abstract: A system is disclosed for monitoring and controlling the deflection of turbine blades of a wind turbine. The system includes a passive position detecting apparatus and a controller. The passive position detecting apparatus may be configured to acquire and transmit data relating directly to a position of at least one of the turbine blades. The controller may be configured to receive the data from the passive position detecting apparatus and compare such data to a known position reference to determine turbine blade deflection.

Abstract: The present invention pertains to the use of certain flavour enhancing compounds obtainable from an Allium species. In one embodiment, seeds from chives, leeks, ramson and other onions are used for conveying strong kokumi flavour enhancing effects on food products without imparting an onion or garlic-like off taste. These flavour enhancing compounds are also useful for the preparation of Amadori products, which are also used as kokumi flavour enhancing compounds.
