Publication number: 20200027018Abstract: In general, embodiments of the present invention provide systems, methods and computer readable media for automated dynamic data quality assessment. One aspect of the subject matter described in this specification includes the actions of receiving a data quality job including a new data sample; and, if the new data sample is determined to be added to a reservoir of data samples, sending a quality verification request to an oracle; receiving a new data sample quality estimate from the oracle; and adding the new data sample and estimate to the reservoir. A second aspect of the subject matter includes the actions of receiving, from a predictive model, a judgment associated with a new data sample; analyzing the new data sample based in part on the judgment to determine whether to send a new data sample quality verification request to an oracle; and, if a new data sample quality estimate is received from the oracle, determining whether to add the new data sample and the judgment to the reservoir.Type: ApplicationFiled: June 6, 2019Publication date: January 23, 2020Inventors: Mark Thomas Daly, Shawn Ryan Jeffery, Matthew DeLand, Nick Pendar, Andrew James, David Alan Johnston

Publication number: 20190378044Abstract: In general, embodiments of the present invention provide systems, methods and computer readable media for an adaptive oracle-trained learning framework for automatically building and maintaining models that are developed using machine learning algorithms. In embodiments, the framework leverages at least one oracle (e.g., a crowd) for automatic generation of high-quality training data to use in deriving a model. Once a model is trained, the framework monitors the performance of the model and, in embodiments, leverages active learning and the oracle to generate feedback about the changing data for modifying training data sets while maintaining data quality to enable incremental adaptation of the model.Type: ApplicationFiled: August 21, 2019Publication date: December 12, 2019Inventors: Shawn Ryan Jeffery, David Alan Johnston, Jonathan Esterhazy, Gaston L'Huillier, Hernan Enrique Arroyo Garcia

Patent number: 10410225Abstract: Systems, apparatus, and methods for determining unique contacts from a collection or pool of merchant data are discussed herein. Some embodiments may provide for an apparatus including circuitry configured to determine programmatic match results indicating whether different instances of merchant data match (e.g., describe the same contact). The circuitry may further determine probabilities of precision or recall errors with the programmatic match results. Programmatic match results having a high probability of error may be annotated by a user to generate user match results. The user match results may be used to generate a more reliable contacts database including unique contacts, as well as to train and/or update the match scoring algorithm. As such, the accuracy of machine-implemented binary classification is improved.Type: GrantFiled: June 30, 2015Date of Patent: September 10, 2019Assignee: Groupon, Inc.Inventors: David Alan Johnston, Matthew DeLand, Shawn Jeffrey, Taylor Raack

Patent number: 9820416Abstract: A shielding cage with an improved construction is disclosed that permits such cages to be more closely spaced together when a plurality of them are arranged in side-by-side arrays of cages. The cage is formed from a sheet metal blank that is stamped and formed to define sidewalls, top wall, bottom wall and a rear wall. In one embodiment, the ends of the blank are formed with interengaging elements in the form of tabs and slots that interfit within the plane of one of the cage walls, thereby eliminating the need for projections disposed on the sidewalls of the cage.Type: GrantFiled: March 18, 2014Date of Patent: November 14, 2017Assignee: Molex, LLCInventors: Richard Miklinski, Kenneth Janota, Michael Alan Johnston

Publication number: 20130062071Abstract: A technique facilitates controlling flow in a wellbore with a simplified valve. The design of the valve also enables reduction in the overall length of the valve to improve spatial considerations. The valve comprises a valve component, e.g. a flapper, movable between a closed position and an open position. A flow tube is designed to selectively open the valve component with reduced travel, thus enabling a shortened flow tube. The short flow tube enables use of valve housings, springs, and other valve components having a reduced length.Type: ApplicationFiled: September 14, 2011Publication date: March 14, 2013Applicant: SCHLUMBERGER TECHNOLOGY CORPORATIONInventors: Gary L. Rytlewski, Stephen Dennis Parks, Russell Alan Johnston, David James Biddick

Patent number: 8300632Abstract: The system and method described herein allows for full monitoring and recording of SIP calls by using standard SIP messages. During the call set up between a first SIP device and a second SIP device, information is derived from a first SIP INVITE message from a first SIP device. Information is then derived from a response message from the second SIP device. The monitor/recorder receives one or more SIP INVITE messages to set up a first media stream from the first SIP device and a second media stream from the second SIP device to the monitor/recorder. The monitor/recorder receives the first and/or second media stream. The monitor/recorder then records the first and/or second media stream. In addition, the system and method provide for recording on demand, required recording, and pause-and-resume recording of SIP calls.Type: GrantFiled: September 16, 2008Date of Patent: October 30, 2012Assignee: Avaya Inc.Inventors: Sheldon Davis, Alan Johnston, Valentine Matula

Publication number: 20110253392Abstract: A technique enables control over flow in a wellbore with a flow control system. The flow control system combines a flow reduction mechanism with a flow control device, such as a valve. The flow reduction mechanism comprises a closure member which can be selectively moved between an unactuated and actuated position, allowing relatively greater flow through the flow control device in the unactuated position. The flow reduction mechanism actuates prior to or in conjunction with the flow control device to reduce flow and thus reduce the loading forces that would otherwise act against the flow control mechanism upon closure of the flow control device.Type: ApplicationFiled: June 28, 2011Publication date: October 20, 2011Applicant: SCHLUMBERGER TECHNOLOGY CORPORATIONInventors: Dwayne May, David McCalvin, Paul Gordon Goughnour, David James Biddick, Russell Alan Johnston

Patent number: 7845412Abstract: A technique for subsea intervention operations enables pressure control to be accomplished at the surface while borehole fluid control is exercised at the seabed. A compliant guide extends between a subsea well installation and a surface location, such as a surface intervention vessel. A buffer fluid is deployed within the compliant guide to maintain the borehole fluids proximate the seabed. The buffer fluid also enables pressure control over the buffer fluid and the borehole fluid to be performed from the surface. Additionally, a flexible conveyance can be used to move intervention tools through the compliant guide.Type: GrantFiled: February 6, 2007Date of Patent: December 7, 2010Assignee: Schlumberger Technology CorporationInventors: Andrea Sbordone, Eric Smedstad, Rene Schuurman, Alan Johnston, Axel Destremau, Yves Le Moign

Patent number: 7835110Abstract: A micro-electromechanical systems (MEMS) disc drive includes high-precision and integrated components to allow for increased functionality, robustness and reduced size as compared to currently produced disc drives. Integrating multiple subcomponents of the disc drive using batch processing provides low manufacturing costs. Furthermore, using MEMS techniques, new features can be added to disc drives. For example, an environmental control component, an accelerometer and/or a thermometer may be integrated into the housing of the disc drive.Type: GrantFiled: January 23, 2007Date of Patent: November 16, 2010Assignee: Seagate TechnologyInventors: Alan Johnston, Roger Hipwell, Hans Leuthold, Song S.

Patent number: 7826171Abstract: In general, the invention is directed to techniques for integrated interconnects with a set of disc drives. The interconnects allow for a set of disc drives to be positioned in an array; for example, as set of disc drives may be stacked to communicate with a device through a single interface of the device. The interconnects may be formed as vias within the housing of the disc drives. Vias may produced using MEMS techniques, e.g., electroplating, as part of the manufacturing processes of the disc drive itself.Type: GrantFiled: January 23, 2007Date of Patent: November 2, 2010Assignee: Seagate Technology LLCInventors: Alan Johnston, Roger Hipwell, Hans Leuthold, Song S.
