Patent number: 11934361Abstract: A method for the automatic generation of a data model from an SQL statement includes receiving a single SQL statement in a user interface to a data analytics application, parsing the single SQL statement and extracting from the SQL statement different table references. The method also includes, for each one of the table references, directing a selection of all fields available in a corresponding table and storing the available fields in a collection of fields implicated by each table referenced by the table references. Finally, the method includes generating a data model with the fields in the collection of fields and displaying a view of the data model in a user interface of the data analytics application.Type: GrantFiled: July 7, 2022Date of Patent: March 19, 2024Assignee: Google LLCInventors: Colin Zima, Jonathan Swenson, Jamie Davidson, Julian Hyde

Patent number: 10310003Abstract: This application relates to methods and apparatus for fault protection in a DC power transmission network or grid that aid in determining the location of a fault in the network. The method involves, in the event of a fault, controlling at least one current limiting element of the network so as to limit a fault current flowing to below a first current level which is within the expected current operating range of the network in normal operation, i.e. a safe level. The fault current is then controlled to maintain a non-zero level of fault current flow and the characteristics of the fault current flow at different parts of the network are determined by fault current detection modules. The location of the fault is then determined based on the determined characteristics.Type: GrantFiled: February 18, 2015Date of Patent: June 4, 2019Assignee: General Electric Technology GmbHInventors: Colin Davidson, David Reginald Trainer, Carl Barker, Oleg Bagleybter
