Patent number: 9645875Abstract: The disclosed embodiments provide a system that analyzes telemetry data from a computer system. During operation, the system obtains the telemetry data, which includes first information containing telemetric signals gathered using sensors in the computer system and second information that indicates one or more transaction latencies of software running on the computer system. Upon detecting an upward trend in the one or more transaction latencies, the system analyzes the telemetry data for a correlation between the one or more transaction latencies and one or more environmental factors represented by a subset of the telemetric signals. Upon identifying the correlation between the one or more transaction latencies and an environmental factor, the system stores an indication that the environmental factor may be contributing to the upward trend in the one or more transaction latencies.Type: GrantFiled: March 16, 2015Date of Patent: May 9, 2017Assignee: ORACLE INTERNATIONAL CORPORATIONInventors: Dustin R. Garvey, Kenny C. Gross, Kalyanaraman Vaidyanathan, Debabrata Sarkar

Publication number: 20130270257Abstract: A planar device includes a heating circuit that is disposed between ceramic layers in a planar device and co-fired with the ceramic. The heating circuit material and geometry are controlled so as to provide a targeted resistance characteristic as a function of temperature that allows interchangeability in an engine management system that was designed for a heater circuit based on a material system that cannot be co-fired with the planar device.Type: ApplicationFiled: June 6, 2011Publication date: October 17, 2013Applicant: DELPHI TECHNOLOGIES, INC.Inventors: Debabrata Sarkar, Walter Thomas Symons, Eric P. Clyde, David E. Lemaster, Gerardo I. Hernandez

Publication number: 20130264203Abstract: A planar device includes a heating circuit that is disposed between ceramic layers and co-fired with the ceramic. The heating circuit comprises palladium, and the co-firing of the palladium and ceramic is performed in an oxidizing atmosphere. The formation of defects in the planar device that would otherwise be induced as a result of the palladium oxidizing during the co-firing process is prevented by control of the firing profile, by the geometry of the pattern of the heating circuit, and/or by modifying the palladium to reduce its tendency to oxidize.Type: ApplicationFiled: June 4, 2011Publication date: October 10, 2013Applicant: DELPHI TECHNOLOGIES, INC.Inventors: Oscar Gamboa, Walter T. Symons, Eric P. Clyde, Kaius K. Polikarpus, Debabrata Sarkar

Patent number: 6731031Abstract: A heat sink device for retaining a heat dissipating object includes a substrate having an aperture configured therethrough to receive the object and an extruded portion extending from a surface of the substrate defining the aperture. The extruded portion is configured to receive the object and increase a surface area available for heat transfer from said object in said aperture relative to without said extruded portion.Type: GrantFiled: October 8, 2002Date of Patent: May 4, 2004Assignee: Delphi Technologies, Inc.Inventors: Debabrata Sarkar, Michael Duane Bradfield, Olen L. Phillips

Patent number: 6727612Abstract: A plastic fastener is disclosed. The fastener may be employed in a vehicle generator. The fastener has a plastic body extending through an aperture of a first component and through an aperture of a second component. The body has a first distal head that retainingly abuts the opening of the aperture of the first component. The plastic body also has a second distal head that retainingly abuts the opening of the aperture of the second component. The configuration of the body secures the first component to the second component. The invention further provides a method of fastening components of a vehicular generator. A plastic body with first and second studs is over molded about a first generator component. At least one stud may be extended through an aperture of a second generator component. The studs are then formed into distal heads to secure the first component to the second component.Type: GrantFiled: October 8, 2002Date of Patent: April 27, 2004Assignee: Delphi Technologies, Inc.Inventors: Michael L. Hull, Debabrata Sarkar, Steve J. Shields

Publication number: 20030071528Abstract: A through-bolt for use with an AC generator has a housing including a drive-end portion and a mounting-end portion. A stator is mountable between the drive-end portions. A rotor is mounted for rotation within the housing. One of the end portions includes a plurality of circumferentially spaced ears having first apertures therein and the other end portion includes a corresponding plurality of circumferentially spaced ears having threaded apertures therein. The through-bolt is inserted through one of the first apertures and received in one of the threaded apertures to bolt the housing ends together against the stator. The through-bolt is subject to bending stress since it does not operate on a solid stack up, regardless of alignment. The through-bolt comprises a head portion, an elongated shank portion, and a threaded portion extending from the elongated shank portion.Type: ApplicationFiled: October 12, 2001Publication date: April 17, 2003Inventors: Steve J. Shields, Debabrata Sarkar

Patent number: 5845330Abstract: A database management system incorporating an intermediate level of storage medium. Software of the DBMS controls the transfer of data between a primary, secondary and intermediate storage mediums. This transfer is under control of the DBMS and is not transparent to the DBMS. The intermediate storage medium has an access time that is shorter than the access time of the secondary storage medium. During operation of the DBMS, data is read from the secondary storage medium and held in the primary storage medium until the storage medium is full. Thereafter, as additional data is read by the DBMS from the database stored on the secondary storage medium, data is transferred to the intermediate storage medium under control of the DBMS, thus preserving the benefit of having the data read into the primary storage medium.Type: GrantFiled: July 3, 1996Date of Patent: December 1, 1998Assignee: Sun Microsystems, Inc.Inventor: Debabrata Sarkar
