  • Patent number: 8117194
    Abstract: Multilingual document searches are performed by ordering and filtering localized documents in different languages based on user preferences. Documents are indexed in a global search engine index using an identifier property and a language property permitting all relevant documents to be retrieved in a single search engine query. By storing documents with their identifier and language properties, documents from different cultures but with same content can be treated as equivalent. Results of the initial search include a multilingual set of documents ranked in order of relevance. Result sets are then post-processed using a data resource indicating for each multilingual user interface combination, which language version of each document should be returned. The initial search result are then transformed into a relevance based ordered list treating documents in different languages having same content as equivalent.

  • Patent number: 7711729
    Abstract: Search and filtering of documents with different metadata schemata is enabled using a single index that supports a single schema through decorated namespaces. Each metadata schema submitted to a system is assigned a unique identifier and property names associated with the schema are prefixed with the unique identifier. A single-valued, decorated property is used to indicate whether a submitted document is part of a registered schema in the system. The single-valued properties are converted to a search index table that enables resource-optimized searching and filtering of documents eliminating documents of other schemata by simply checking the association property.

  • Publication number: 20050234407
    Abstract: The fluid delivery system generally includes a source of injection fluid, a pump device a fluid path set disposed between the source of injection fluid and the pump device, and a fluid control device. The fluid path set includes a multi-position valve. The fluid control device is operatively associated with the fluid path set and includes a valve actuator adapted to operate the multi-position valve. The valve actuator is adapted to close the multi-position valve to isolate the pump device from a patient and stop flow of the injection fluid to the patient at substantially any pressure or flow rate generated by the pump device for delivering a sharp bolus of the injection fluid to the patient. The valve actuator is generally adapted to selectively place the pump device in fluid communication with the source of injection fluid for supplying the injection fluid to the pump device and the patient.

  • Patent number: 4541988
    Abstract: A constant temperature catalytic gas detection instrument (10) has a gas sensor (14) whose operating temperature is maintained within a predetermined range by a novel control circuit. The gas sensor includes a reference element (16) and an active element (18) on which a metal oxide catalyst reacts with the combustible gas. First and second driver circuits (30 and 36) are provided for presenting operating voltages to the active element (18) and the reference element (16), respectively, of the gas sensor (14). The first driver (30) controls the power to the active element (18), to maintain its temperature within a predetermined operating range. The second driver (36) responds to changes in the power through the active element (18) with respect to the current through the active element (18), causing the current in the reference element (16) to track the current in the active element (18).
