Publication number: 20240134850Abstract: The present disclosure is related to techniques for converting a natural language utterance to a logical form query and deriving a natural language interpretation of the logical form query. The techniques include accessing a Meaning Resource Language (MRL) query and converting the MRL query into a MRL structure including logical form statements. The converting includes extracting operations and associated attributes from the MRL query and generating the logical form statements from the operations and associated attributes. The techniques further include translating each of the logical form statements into a natural language expression based on a grammar data structure that includes a set of rules for translating logical form statements into corresponding natural language expressions, combining the natural language expressions into a single natural language expression, and providing the single natural language expression as an interpretation of the natural language utterance.Type: ApplicationFiled: May 21, 2023Publication date: April 25, 2024Applicant: Oracle International CorporationInventors: Chang Xu, Poorya Zaremoodi, Cong Duy Vu Hoang, Nitika Mathur, Philip Arthur, Steve Wai-Chun Siu, Aashna Devang Kanuga, Gioacchino Tangari, Mark Edward Johnson, Thanh Long Duong, Vishal Vishnoi, Stephen Andrew McRitchie, Christopher Mark Broadbent

Publication number: 20210288532Abstract: A permanent magnet rotor core includes a plurality of rotor poles circumferentially-spaced about a central axis and including a first rotor pole and an adjacent second rotor pole that each include an outer wall, and wherein the rotor core includes a rotor diameter. The rotor core also includes a plurality of radial apertures alternately-spaced with the plurality of rotor poles. The rotor core also includes a first protrusion extending from the first rotor pole into a first radial aperture of the plurality of radial apertures positioned between the first rotor pole and the second rotor pole. The rotor core further includes a second protrusion extending from the second rotor pole into the first radial aperture such that a circumferential opening is defined between the first protrusion and the second protrusion. The opening extends a first length of between approximately 0.052% and approximately 0.058% of the rotor diameter.Type: ApplicationFiled: March 12, 2020Publication date: September 16, 2021Inventors: Mark Thiele, Greg Heins, Subhash Brahmavar, Steve Long, Lester Benjamin Manz, Kerry Shelton

Patent number: 9845773Abstract: An engine system having a flowpath between a junction upstream of a turbocharger and an intake manifold that includes an ejector and an aspirator connected in parallel relative to one another within the flowpath is disclosed. The motive flow through the ejector is in the opposite direction relative to the direction of the motive flow through the aspirator, and both the ejector and the aspirator have a suction port fluidly coupled to a device requiring vacuum. The engine system also includes a first check valve disposed in control of the motive flow through the ejector and a second check valve disposed in control of the motive flow through the aspirator and may also include a control valve in fluid communication within the flowpath upstream or downstream of the ejector and the aspirator that controls the flow into and/or out of both thereof.Type: GrantFiled: July 17, 2014Date of Patent: December 19, 2017Assignee: Dayco IP Holdings, LLCInventors: David E. Fletcher, Brian M. Graichen, Matt Gilmer, Andrew Niedert, Steve Long

Patent number: 9145824Abstract: An engine system having a compressor coupled to an engine and supplying air to an intake manifold, a throttle controlling the supply of air from the compressor to the intake manifold, a vacuum reservoir, an aspirator having its motive section in fluid communication with the air intake system upstream of the compressor and its discharge section in fluid communication downstream of the compressor and a suction port in fluid communication with the vacuum reservoir, a compressor recirculation valve having a pneumatic control chamber in fluid communication with downstream air from the compressor and in fluid communication with the vacuum reservoir, a gate valve controlling the fluid communication of the pneumatic control chamber of the compressor recirculation valve with the downstream air and the vacuum reservoir, and a bleed line having a bleed valve in fluid communication with the vacuum reservoir and the pneumatic control chamber of the compressor recirculation valve.Type: GrantFiled: June 13, 2014Date of Patent: September 29, 2015Assignee: DAYCO IP HOLDINGS, LLCInventors: Dave Fletcher, Brian M. Graichen, Keith Hampton, Matt Gilmer, James H. Miller, Steve Long

Patent number: 9133852Abstract: An engine system having a compressor coupled to an engine and supplying air to an intake manifold, a throttle controlling the supply of air from the compressor to the intake manifold, a compressor recirculation valve (CRV) having a pneumatic control chamber, and a throttle aspirator having its motive section in fluid communication with an inlet of the throttle and its discharge section in fluid communication with an outlet of the throttle and its suction port in fluid communication with the pneumatic control chamber of the CRV. Such an engine system automatically minimizes surge during boost without a control system activating the CRV. Here, the CRV operates purely on the changes in pressure within the system forming a loop that resets itself. In another embodiment, a gate valve and a vacuum canister may be included rather than having the throttle aspirator directly connected to the CRV's pneumatic control chamber.Type: GrantFiled: June 13, 2014Date of Patent: September 15, 2015Assignee: DAYCO IP HOLDINGS, LLCInventors: Dave Fletcher, Brian M.

Publication number: 20150020524Abstract: An engine system having a flowpath between a junction upstream of a turbocharger and an intake manifold that includes an ejector and an aspirator connected in parallel relative to one another within the flowpath is disclosed. The motive flow through the ejector is in the opposite direction relative to the direction of the motive flow through the aspirator, and both the ejector and the aspirator have a suction port fluidly coupled to a device requiring vacuum. The engine system also includes a first check valve disposed in control of the motive flow through the ejector and a second check valve disposed in control of the motive flow through the aspirator and may also include a control valve in fluid communication within the flowpath upstream or downstream of the ejector and the aspirator that controls the flow into and/or out of both thereof.Type: ApplicationFiled: July 17, 2014Publication date: January 22, 2015Applicant: DAYCO IP HOLDINGS, LLCInventors: David E.
