Patent number: 10260536Abstract: A method is disclosed for determining off-temperature behavior of a solenoid fluid control valve. The method comprises performing a current sweep at a first temperature. The method further comprises choosing a first and second characterization control pressure for characterizing the solenoid fluid control valve. A first current may be determined that corresponds to the first characterization control pressure based on the current sweep, and a first metric may be assigned to the solenoid fluid control valve based on the first current. A second current corresponding to the second characterization control pressure may be determined based on the current sweep, and a second metric may be assigned to the solenoid fluid control valve based on the second current. Information regarding the behavior of the solenoid fluid control valve at a second temperature may be determined based on the first and second metrics.Type: GrantFiled: May 2, 2016Date of Patent: April 16, 2019Assignee: FLEXTRONICS AP, LLCInventors: Hamid Najmolhoda, David Seid

Patent number: 9518679Abstract: A method is disclosed for determining off-temperature accuracy information of a solenoid fluid control valve. The method comprises performing a current sweep at a first temperature, and for at least one command pressure, determining an error in a control pressure based on the current sweep. The error may be determined at the first temperature. A metric may then calculated based on the current sweep, and a pressure error offset may be determined for a second temperature based on the metric. The pressure error offset may describe a difference between the error in control pressure at the first temperature and an expected error in control pressure at the second temperature.Type: GrantFiled: March 21, 2014Date of Patent: December 13, 2016Assignee: Flextronics AP, LLCInventors: David Seid, Ritchie Wycoco Baje, Hamid Najmolhoda

Patent number: 9482356Abstract: An electromagnetic solenoid having a coil wound around a bobbin between first and second flanges for generating a magnetic force is disclosed. An armature having an armature flange at a first end is within an interior portion of the tubular center section of the bobbin and is supported for axial displacement between a first position and a second position. A permanent ring magnet is placed at the first end flange with an inner radial face spaced apart from an outer radial face of the armature flange by a radial gap, with the ring magnet supported by a retainer adjacent to the first end flange and fixed against axial displacement with respect to the bobbin. The solenoid comprises an outer case having a closed bottom at a first end and an open top at a second end and a flux washer disposed in the open top adjacent to a second end of the armature.Type: GrantFiled: September 2, 2014Date of Patent: November 1, 2016Assignee: Flextronics Automotive, Inc.Inventors: David Seid, Hamid Najmolhoda, Klynt Baker, John Kovitz

Patent number: 8494931Abstract: A management application implemented in a computational device maintains priorities corresponding to a plurality of resources coupled to the computational device. Indications for actions to be performed corresponding to occurrences of events are stored to a calendar, wherein the calendar is configurable by a user. A selected indication for an action to be performed is stored to the calendar. In response to an occurrence of an event associated with a selected resource, a priority of the selected resource is determined. The action is performed, based on at least the determined priority of the selected resource and the selected indication for the action stored in the calendar, wherein different actions are performed in response to occurrences of a selected event at different times.Type: GrantFiled: July 8, 2010Date of Patent: July 23, 2013Assignee: International Business Machines CorporationInventors: Jeffrey Alan Calacaterra, Gregory Richard Hintermeister, David Bruce Lection, Alan David Seid
