  • Publication number: 20240150052
    Abstract: Various embodiments of the present disclosure provide a strapping machine with a welding assembly including a counter-pressure plate and a heating element that cooperate to attach two overlapping portions of strap to each other to form a loop of strap around a load. The welding assembly includes various clamps and a leading-strap-end guide that clamp the strap at various points in time during a strapping cycle to prevent the strap from misaligning. After the loop of strap has been formed around the load and the load has been removed from the strapping machine, the welding assembly manipulates the leading end of the strap extending from the strap supply and clamps it via the clamps and the leading-strap-end guide to align the strap for the next strapping cycle.

  • Patent number: 11893025
    Abstract: A source table organized into a set of batch units is accessed. The source table comprises a column of data corresponding to a semi-structured data type. One or more indexing transformations for an object in the column are generated. The generating of the one or more indexing transformation includes converting the object to one or more stored data types. A pruning index is generated for the source table based in part on the one or more indexing transformations. The pruning index comprises a set of filters that index distinct values in each column of the source table, and each filter corresponds to a batch unit in the set of batch units. The pruning index is stored in a database with an association with the source table.

  • Patent number: 11880369
    Abstract: A top K query directed at a table is received. The table is organized into multiple storage units. The top K query comprises a first clause to sort a result set in order and a second clause that specifies a limit on a number of results provided in response to the query. A table scan operator identifies a first set of rows from the table based on a scan set determined for the table and provides the first set of rows to a top K operator. The top K operator determines a current boundary based on the first set of rows and provides the current boundary to the table scan operator. The table scan operator prunes the scan set based on the current boundary and identifies a second set of rows from the table based on the pruning.

  • Patent number: 11872654
    Abstract: A device for structuring a surface of a through opening in a component, in particular a cylinder opening of a cylinder crankcase for an internal combustion engine. The device comprises a lance, which can be moved into the through opening by a displacement device. The lance has means for emitting a laser beam from a laser light source in the direction of the surface of the through opening. A preferably plate-shaped cover is provided, which is designed for placement on an end face of the component. The cover forms a passage opening which is dimensioned such that the lance can be moved through it. A compressed gas feed is integrated into the cover and comprises a connector for connecting to a compressed gas source and forms one or more outlet openings at the edge of the passage opening.

  • Patent number: 11865279
    Abstract: The current document is directed to improved PTA methodologies that significantly decrease the risks of persistent blood-vessel-wall distention and subsequent restenosis and the risks of PTA-induced dissection, hematoma, and pseudoaneurysm when used to treat blood vessels. Similar improved percutaneous-transluminal-interventional methods are used to treat non-vascular vessels. The improved methods include initial selection of balloon length and inflation pressure for initial treatment of primary lesions to minimize the risks of over-inflation and generation of undesirable localized forces during balloon inflation. The improved methods further include higher-pressure treatment of remaining secondary lesions that also minimizes the risks of over-inflation and generation of undesirable localized forces. The improved methods can be practiced using differently sized balloons and conventional instrumentation, but may be facilitated by use of balloon-length-adjustable catheters.

  • Publication number: 20230399224
    Abstract: MEMS devices include a suspended element connected to a fixed part of a substrate by one or more flexures, wherein the one or more flexures are configured to permit movement of the suspended element relative to a fixed part of the substrate. A sensor coupled to the suspended element and a damping structure coupled to the suspended element extends into a gap between the suspended element and the fixed part of the substrate. One or more fluid confinement structures are configured to permit movement of the damping structure within a limited portion of the gap and to confine a viscoelastic fluid to the limited portion of the gap.

  • Patent number: 11803551
    Abstract: A source table organized into a set of micro-partitions is accessed by a network-based data warehouse. A pruning index is generated based on the source table. The pruning index comprises a set of filters that indicate locations of distinct values in each column of the source table. A query directed at the source table is received at the network-based data warehouse. The query is processed using the pruning index. The processing of the query comprises pruning the set of micro-partitions of the source table to scan for data matching the query, the pruning of the plurality of micro-partitions comprising identifying, using the pruning index, a sub-set of micro-partitions to scan for the data matching the query.

  • Publication number: 20230342362
    Abstract: A query directed at a source table organized into a set of batch units is received. The query comprises a regular expression search pattern. The regular expression search pattern is converted to a pruning index predicate comprising a set of substring literals extracted from the regular expression search pattern. A set of N-grams is generated based on the set of substring literals extracted from the regular expression search pattern. A pruning index associated with the source table is accessed. The pruning index indexes distinct N-grams in each column of the source table. A subset of batch units to scan for data matching the query are identified based on the pruning index and the set of N-grams. The query is processed by scanning the subset of batch units.

  • Patent number: 11704320
    Abstract: A table organized into a set of batch units is accessed. A set of N-grams are generated for a data value in the source table. The set of N-grams include a first N-gram of a first length and a second N-gram of a second length where the first N-gram corresponds to a prefix of the second N-gram. A set of fingerprints are generated for the data value based on the set of N-grams. The set of fingerprints include a first fingerprint generated based on the first N-gram and a second fingerprint generated based on the second N-gram and the first fingerprint. A pruning index that indexes distinct values in each column of the source table is generated based on the set of fingerprints and stored in a database with an association with the source table.

  • Patent number: 11593379
    Abstract: A query directed at a table organized into a set of batch units is received. The query comprises a predicate for which values are unknown prior to runtime. A set of values for the predicate are determined based on the query. An index access plan is created based on the set of values. Based on the index access plan, the set of batch units are pruned using a pruning index associated with the table. The pruning index comprises a set of filters that index distinct values in each column of the table. The pruning of the set of batch units comprises identifying a subset of batch units to scan for data that satisfies the query. The subset of batch units of the table are scanned to identify data that satisfies the query.
