Patent number: 11969844Abstract: A method for detecting and compensating CNC tools being implemented in an electronic device, receives from a detector first parameters and second parameters in respect of a first tool. Such first parameters include at least one of service life, blade break information, and blade chipping information of the first tool, and such second parameters include at least one of length extension information, length wear information, radial wear information, and blade thickness wear information of the first tool. Based on the first parameters, instructions to process the workpiece are transmitted or not. Upon receiving the second parameters, instructions to adjust operation of the first tool are transmitted, to compensate for deterioration in normal use.Type: GrantFiled: April 12, 2021Date of Patent: April 30, 2024Assignee: Fulian Yuzhan Precision Technology Co., LtdInventors: Hsing-Chih Hsu, Zhao-Yao Yi, Lei Zhu, Chang-Li Zhang, Er-Yang Ma, Chih-Sheng Lin, Feng Xie, Ming-Tao Luo

Publication number: 20240126764Abstract: Techniques support graph pattern matching queries inside a relational database management system (RDBMS) that supports SQL execution. The techniques compile a graph pattern matching query that includes a bounded recursive pattern query into a SQL query that can then be executed by the relational engine. As a result, techniques enable execution of graph pattern matching queries that include bounded recursive patterns on top of the relational engine by avoiding any change in the existing SQL engine.Type: ApplicationFiled: October 13, 2022Publication date: April 18, 2024Inventors: VLAD IOAN HAPRIAN, LEI SHENG, LAURENT DAYNES, ZHEN HUA LIU, HUGO KAPP, MARCO ARNABOLDI, ANDREW WITKOWSKI, SUNGPACK HONG, HASSAN CHAFI

Each fin structure includes a first region proximate to the semiconductor substrate and a second region distal to the semiconductor substrate. An electrically conductive layer is formed between the first regions of a first adjacent pair of fin structures. A gate electrode structure is formed extending in a second direction substantially perpendicular to the first direction over the fin structure second region, and a metallization layer including at least one conductive line is formed over the gate electrode structure.Type: ApplicationFiled: November 7, 2023Publication date: February 29, 2024Applicant: Taiwan Semiconductor Manufacturing Company, Ltd.Inventors: Hung-Li CHIANG, Chih-Liang CHEN, Tzu-Chiang CHEN, I-Sheng CHEN, Lei-Chun CHOU

Patent number: 11915785Abstract: A request to perform a write operation at a memory device is received. Current wordline start voltage (WLSV) information associated with a particular memory segment of the plurality of memory segments is retrieved. The write operation is performed on the particular memory segment. In a firmware record in a memory sub-system controller, information is stored indicative of a last written memory page associated with the particular memory segment on which the write operation is performed. The firmware record is managed in view of the information indicative of the last written memory page associated with the performed write operation. Each entry of the firmware record comprises one or more identifying indicia associated with a respective memory segment, at least one of the identifying indicia being a wordline start voltage (WLSV) associated with the respective memory segment.Type: GrantFiled: January 26, 2021Date of Patent: February 27, 2024Assignee: Micron Technology, Inc.Inventors: Jiangang Wu, Lei Zhou, Jung Sheng Hoei, Kishore Kumar Muchherla, Qisong Lin

Patent number: 11151134Abstract: Described is an approach for performing an efficient processing of table functions/polymorphic table functions. The approach does not create additional cursors for processing a table or polymorphic table function invoked within a SQL statement. Instead, the approach handles the SQL statement that invokes the table/polymorphic table function as a single cursor.Type: GrantFiled: June 13, 2018Date of Patent: October 19, 2021Assignee: Oracle International CorporationInventors: Atif Chaudhry, Lei Sheng, Shashaanka Agrawal

Patent number: 10635671Abstract: Techniques herein optimize sort-merge join method for a band join. In an embodiment, for a query comprising a query block specifying a join between a first table and a second table, a band join condition is detected between the first table and the second table. Once the band join condition in detected, an execution plan is generated and executed. The execution of the execution plan includes: for a first row of at least a subset of first sorted rows, scanning second rows from a set of second sorted rows, joining each of said second rows with said first row, and ceasing to scan when encountering a row from the second sorted rows that falls outside a bound of said band join condition. Techniques also include parallelizing a workload by overlapping the distribution of rows to the same slave process and computing cost and cardinality estimation for enhanced band join.Type: GrantFiled: October 5, 2017Date of Patent: April 28, 2020Assignee: Oracle International CorporationInventors: Lei Sheng, Rafi Ahmed, Andrew Witkowski, Sankar Subramanian

Publication number: 20200125569Abstract: Disclosed is an approach to define non-SQL functions as a SQL macro, which is then processed inline with SQL statements. By inlining the macro into SQL, this approach avoids cross-engine context switches as well as making it possible for a SQL query optimizer to generate better plans that execute more efficiently.Type: ApplicationFiled: September 13, 2019Publication date: April 23, 2020Applicant: Oracle International CorporationInventors: Atif CHAUDHRY, Chandrasekharan IYER, Lei SHENG, Agrawal SHASHAANKA

Patent number: 8041731Abstract: Techniques are described herein for supporting efficient evaluation of pivot operations. In an embodiment, a pivoting query on a data table is received. The query identifies pivot columns, measure columns, and grouping columns. In response to receiving the query, a staging table that comprises new pivot columns, aggregated columns, and new grouping columns may be created. For each particular unique combination of values of the grouping columns and the pivot columns in the data table, stored values in the measure columns in the data table are aggregated for certain rows in the plurality of rows in the data table. Each row of the certain rows comprises the each particular unique combination of values of the grouping columns and the pivot columns in the data table. Results of aggregating are stored in the staging table. Data that has been populated in the staging table is transposed into a result set.Type: GrantFiled: July 21, 2008Date of Patent: October 18, 2011Assignee: Oracle International CorporationInventors: Srikanth Bellamkonda, Lei Sheng, Sankar Subramanian
