摘要： Embodiments of the invention provide a pool cleaner for use in a swimming pool or spa including a front wheel assembly and a scrubber assembly. The scrubber assembly is engagable with inner gear teeth of the front wheel assembly so that rotation of the front wheel assembly causes rotation of the scrubber assembly. The scrubber assembly includes at least one pinion gear and at least one end bracket rotatable about the at least one pinion gear to substantially lift the scrubber assembly over objects in the swimming pool or spa.

摘要： A method for acquiring MR data from a beating heart during subject respiration includes a prescan phase in which a respiratory compensation table and a k-space sampling schedule are produced. The k-space sampling table is produced using a spatio-temporal model of the beating heart and time sequential sampling theory. During the subsequent scan an imaging pulse sequence which is prospectively compensated for respiratory motion is used to acquire k-space data from the subject. The imaging pulse sequence is repeated to play out the phase encodings in the order listed in the k-space sampling schedule.

摘要： An aspect of the present invention facilitates efficient updating of rows in a data warehouse. In one embodiment, a sequence of identifiers is allocated to rows of data elements received earlier, and then inserted along with the received data elements in a table according to the defined by the sequence of identifiers. On receiving data elements as updates to the rows having associated identifiers, the received data elements are sorted according to the order of the associated identifiers and updates of the rows are performed successively in the sorted order of identifiers. According to another aspect, the above features are performed when (target) fact/dimension tables in the data warehouse are sought to be updated based on transformations/computations performed on data in other (source) fact/dimension tables.

摘要： Embodiments of the invention provide a system and method for operating a pressure-driven pool cleaner. The system includes a hydraulic timer assembly and a venturi vacuum assembly. The method includes directing water to the hydraulic timer assembly and the venturi vacuum assembly, driving the pressure-driven pool cleaner with the hydraulic timer assembly according to a timed movement cycle including a combination of backward movement and forward movement, and suctioning debris with the venturi vacuum assembly. The venturi vacuum assembly is independent of the hydraulic timer assembly so that suctioning occurs during the backward movement and the forward movement.

摘要： Techniques for transforming records prior to loading the records into a data warehouse in an efficient manner. In one embodiment, instead of using lookup transformations, a database operation such as an outer join operation is used to transform records stored in a fact staging table to add foreign keys to the records corresponding to the dimension tables that are associated with a fact table in a data warehouse to which the records are to be loaded. Since the outer join operation is memory intensive, a determination is made as to which dimension tables from the multiple dimension tables associated with the fact table are suitable, from a performance perspective, for the outer join operation. Only those suitable dimension tables are outer joined to the fact staging table to add the foreign keys for the outer joined dimension tables to the fact staging table records. Lookup transformations may be used to add foreign keys to the fact staging table records for the non-suitable dimension tables. The transformed fact records with the foreign keys may then be loaded into the fact table in the data warehouse.
