摘要:
Methods and apparatus for supporting an additional data source in a system adapted for processing data from one or more data sources are disclosed. A design-time driver for the additional data source is obtained, where the design-time driver supports the definition of data including one or more fields of the additional data source to retrieve from the additional data source. In addition, a run-time driver for the additional data source is obtained, where the run-time driver supports retrieval of data corresponding to the one or more fields from the additional data source and where the run-time driver has a second application programming interface. The design-time driver is executed via a first application programming interface, where the first application programming interface enables definition of the data including the one or more fields to be retrieved from the additional data source. The data is then retrieved from the additional data source via the run-time driver using the second application programming interface.

Methods and apparatus for joining two or more tables are disclosed. A query including a join query is received, where the join query requests that a new table be generated from data obtained from two or more tables, where the two or more tables are stored at two or more data sources. One or more columns for each of the tables for which data is to be obtained are identified from the query. A query plan to execute the query to obtain data for the identified columns from the two or more tables is then generated.

摘要:
Methods and apparatus for joining two or more tables are disclosed. A query including a join query is received, where the join query requests that a new table be generated from data obtained from two or more tables, where the two or more tables are stored at two or more different data sources. Data from the tables is retrieved corresponding to the query. A new table is then generated from the retrieved data.
摘要:
A kiosk comprises: a motion sensor; electronics; and a speaker. The motion sensor senses a customer adjacent to the kiosk. The electronics, which are communicatively coupled to the sensor, determine if the customer has lingered by the kiosk for a period of time. The speaker, which is communicatively coupled to the electronics, emits an aural greeting if it is determined that the customer has not lingered.
摘要:
Architecture that enhances the visual experience of a slide presentation by animating slide content as “actors” in the same background “scene”. This is provided by multi-layered transitions between slides, where a slide is first separated into “layers” (e.g., with a level of transparency). Each layer can then be transitioned independently. All layers are composited together to accomplish the end effect. The layers can comprise one or more content layers, and a background layer. The background layer can further be separated into a background graphics layer and a background fill layer. The transition phase can include a transition effect such as a fade, a wipe, a dissolve effect, and other desired effects. To provide the continuity and uniformity of presentation the content on the same background scene, a transition effect is not applied to the background layer.
摘要:
A vehicle (12) including a control system (18) is used for controlling vehicle attitude or angular velocity (38). The processor (24) is coupled to a star sensor or tracker (22) and a memory (30) that may include a star catalog (32), and an exclusion list (36). The exclusion list (36), a list of stars to be temporarily excluded from consideration when determining attitude or angular velocity or relative alignment of star sensors or trackers, is calculated on-board. Such a calculation prevents the necessity for a costly, periodic, ground calculation and upload of such data. By manipulating the star catalog, or sub-catalogs derived from said catalog, based upon the exclusion list (36), measurements of such excluded stars are prevented from corrupting the attitude or angular velocity or alignment estimates formulated on board.
摘要:
A source-matching service may gather information from one or more interest resources, then process the information to generate a set of keywords corresponding to an item or type of item in which users of a network-based service may be interested. Optionally, the source-matching service may identify a source to provide an item described by the interest keywords through the network-based service, and offer the source the opportunity to provide the item described by the interest keywords through the network-based service.

Methods, apparatus and articles of manufacture therefor, are disclosed sharing and searching annotated document collections. In one embodiment, the method may be performed by: transforming a plurality of document identifiers and their associated set of tags into a set of URL/TAG pairs; constructing a bigraph using the set of URL/TAG pairs; using the bigraph to compute tag profiles and document profiles using spreading activation for document identifiers and tags in the set of URL/TAG pairs; for a selected tag or document, identifying a tag profile or a document profile associated with the selected tag or document, respectively; arranging by relevance those tags or documents in the identified tag profile or document profile associated with the selected tag or document, respectively.
摘要:
An improved process is provided for the production of chlorine dioxide and chlorine wherein a chlorine dioxide generator may be operated interchangeably in either sulfuric acid or hydrochloric acid mode without changing acidity levels or evacuating the liquor of one mode and refilling with liquor of the second mode before continuing generation. The versatile process for production of chlorine dioxide comprises maintaining saturated solutions of both alkali metal chloride and alkali metal sulfate in the generator at an acid normality of from about 2 to about 11 in the presence of a small amount of catalyst selected from the group consisting of vanadium pentoxide, silver ions, manganese ions, dichromate ions and arsenic ions. Thus, the instant process provides high yields of chlorine dioxide even at high acidities making it possible to manufacture balanced quantities of saltcake and alkali metal chloride by-products as may be required.
