Abstract: Embodiments relate to techniques for performing data blending operations across multiple different data sets comprising data structures with columns and rows. The data sets may be classified and displayed in a visualization (i.e., chart) in a client interface. Columns and rows from the blended data sets may be mapped together (i.e., linked). Updates to the visualization, including adding elements from the data sets, may trigger a data blending process on the backend server in communication with a database. The server may blend the specified data by generating a runtime artifact representing a calculation graph for the blend operation and query the database to retrieve a resulting data set. The data blending operation may comprise collapsing dimensions of a primary data set with linked dimensions of a secondary data sets into a blended column and aggregating values of measures in rows of the blended column of the resulting data structure.

Abstract: In one embodiment, a method receives a query for data in a database system and calls a plurality of engines to analyze information for the query. A calculation graph is generated from at least a portion of the plurality of engines where each of the at least a portion of the plurality of engines add a node to the calculation graph based on analyzing of the information for the query. Then, the method executes the query by calling the nodes of the calculation graph. Each node uses metadata added to the node from a respective calculation engine to perform a calculation for the node. Then, a result of the query is output based on the respective calculations performed by the nodes.

Abstract: Data blending operations are disclosed configured to blend data from a primary data set and a secondary data set. Primary and secondary data structure models are generated reflecting selected dimensions and measures of the primary and secondary data structure models upon which the data blending operation is to be performed. Each dimension and measure in the primary and secondary data structure models includes a local identifier. Unique global identifiers are assigned to each local identifier of the primary and secondary data structure models. Client queries are generated and communicated to a backend server to perform data blending on the selected dimensions and measures of the primary data set and the secondary data set. The client queries may comprise the global identifiers and mapping information between the global identifiers and local identifiers. The backend system retrieves a resulting data set in response to the data blending operation based on this mapping.

Abstract: In an example embodiment, a bundle loader is run in response to a communication from an application. The communication may indicate that the plurality of bundles of components in the application is to be executed. The plurality of bundles may include at least one bundle having a component that depends on a dependency component in another of the plurality of bundles. A configuration file indicating a set of the plurality of bundles to load in the bundle loader is received. The bundle loader is operated to load a bundle manifest for each bundle in the set of the plurality of bundles to load. Then, for each of the bundles in the set of plurality of bundles to load, the bundle is activated if no unactivated dependency component exists for any component in the bundle.

Abstract: Various embodiments of systems and methods for providing a set of placement options to a user when a new report object is requested to be placed in an area of the report are described herein. One or more existing report objects are associated with the area of the report. The set of placement options are determined based on at least one of the following: area type of the area in which the new report object is requested to be placed and a semantic relationship between the new report object and the one or more existing report objects. In one embodiment, the area of the report includes a sub-area. The set of placement options for a sub-area is determined based on the semantic relationship of new report objects and the existing report objects associated with the area and the sub-area.

Abstract: Various embodiments of systems and methods for providing a semantic guidance in a report are described herein. A mismatch is identified between a report object positioned at a location on the report and the area with which the location is associated. The mismatch is identified based on the metadata of the report object and the attribute of the area with which the location is associated. In one embodiment, the identified mismatch is displayed to a user in a tooltip. In one embodiment, if an attribute of an area of the report is changed, the mismatch is identified between the report object present in the area and the changed attribute.

Abstract: The invention relates to a hand-held instrument, for dental or surgical use, intended to rotate a rectilinear detachable tool (13). It comprises: a tubular sheath (1); a hollow shaft (3) rotatably mounted inside the sheath and consisting of an upstream portion (5) and a downstream portion (6) which in turn comprises an upstream portion (11) partially clamped around the upstream portion (5) of the shaft and a downstream portion (12) of which the inside diameter substantially matches the outside diameter of the tool (13); a clamp (14) rigidly rotationally connected to the shaft (3) but movable along the axis thereof, which clamp is placed inside and concentric with the upstream portion (5) of the shaft; and means for moving the clamp (14) longitudinally so that the jaws (17) thereof penetrate under the upstream portion (5) of the shaft (3) thereby gripping the tool.

Abstract: A device for releasing a tool from a tool fastening mechanism of a dentist's handpiece comprises a push-piece that is held in an outer, inoperative position by a spring, and a slide mounted on a rotor of the dentist's handpiece. Upon being pressed, the push-piece engages the slide to release a tool fastened in the rotor. In order to prevent the push-piece from overheating when it is in contact with the slide while the slide is rotating at high speed, the push-piece carries a disc and the slide carries a ball. The disc and the ball are for instance made of sintered hard metal and are located where the push-piece and the slide engage such as to have substantially a point contact between them on the rotational axis of the slide.

Abstract: The dental instrument with handpiece comprises an intermediate section (4) containing a micromotor. A handpiece (1) with a head (2) carrying a tool (3) is plugged in the front end of the intermediate section (4) so as to form a unit block therewith. At the back end thereof, the intermediate section (4) carries an adaptor comprising a part (10) integral with said section (4), and a part (9) which may rotate freely in the part (10) about the instrument axis. Said part (9) receives the adapter (8) integral therewith, of a flexible sheath (7) which connects the instrument to a supply station and brings thereto, besides the power and driving flux for the micromotor, air and water for a jet (15) of fine water droplets in the direction of the work location, as well as a lighting through an optical fiber thereof, through conduits (6,11,12,13,21) contained in the sheath (7) and going through the adaptor (9,10) separately.

Abstract: In a dental turbine, having a laterally displaceably arranged rotor assembly including a shaft mounted in upper and lower ball bearings and having its lower end protruding through a bore provided in the nose of the turbine and forming a gap or space with the bore for accommodating the lateral displacement of the shaft lower end thereat a protective sleeve (1) is fitted to the outer ring (2) of the lower ball bearing, and extends below the bearing, then along the lower end of the shaft (4) and into the space (5) formed between the shaft (4) and the bore (6) in the nose (7) of the turbine to provide a relatively minute gap or space between the inner surface of the lower portion of the sleeve and the lower end of the shaft and a resultant reduced size gap or space between the outer surface of the lower portion of the sleeve and the inner surface of the bore in the nose.

Abstract: A holder for a dental drill is formed by a helical spring drivingly connected to a driven rotor. The normal internal diameter of the spring is slightly less than the diameter of the shank of the drill to be used. Axial insertion of the drill into one end of the spring causes the spring to compress in length and thus increase in diameter sufficiently to receive the drill shank and frictionally grip the same. Means are provided for expanding the spring to release the drill.
