Patent number: 9458876Abstract: An elastically deformable alignment fastener has the form of a unitary object having a head portion and an integrally formed body portion. The body portion has an elastically deformable lobular hollow tube having a proximal end proximate the head portion and a distal end axially displaced from the head portion. The lobular hollow tube has an outer surface having one or more retention features oriented to provide a plurality of radially extending engagement surfaces along a length of the hollow tube. The head portion has a flange that circumscribes the proximal end of the lobular hollow tube. Portions of the elastically deformable lobular hollow tube when inserted into circular apertures of first and second components elastically deform to an elastically averaged final configuration that aligns the first and second components in four planar orthogonal directions.Type: GrantFiled: August 28, 2013Date of Patent: October 4, 2016Assignee: GM GLOBAL TECHNOLOGY OPERATIONS LLCInventors: Steven E. Morris, Marc J. Tahnoose, Michael E. McGuire, Jennifer P. Lawall

Patent number: 9349224Abstract: Methods and apparatus are provided for notifying a user of a condition of a vehicle. The method includes receiving sensor data from one or more sensors associated with one or more systems of the vehicle. The one or more sensors observe conditions associated with the one or more systems of the vehicle. The method includes receiving a preference for notifications from a user of the vehicle. The method further includes generating at least one notification based on the preference and the sensor data, and communicating the at least one notification to a device of the user.Type: GrantFiled: October 2, 2013Date of Patent: May 24, 2016Assignee: GM GLOBAL TECHNOLOGY OPERATIONS LLCInventors: Marc J. Tahnoose, Michael E. McGuire

Patent number: 8616944Abstract: A pressure relief valve for relieving air pressure from an automotive vehicle interior. The pressure relief valve mounts on a valve mounting location that surrounds a body opening and includes flexible interleaved flaps and a securing mechanism. The flaps cover the body opening, with each of the flaps being generally triangular in shape and having an outer end adjacent to the valve mounting location and a pair of sides extending from the outer end inward to an inner corner, with the inner corners meeting to form a peak. The interleaved flaps form a generally pyramidal-shape that angles away from the automotive vehicle interior as the interleaved flaps extend inward from the outer ends toward the peak. The securing mechanism is secured to the radially outer ends of the flaps and to the valve mounting location.Type: GrantFiled: September 4, 2009Date of Patent: December 31, 2013Assignee: GM Global Technology Operations LLCInventors: Kimberly A. Chambo, Marc J. Tahnoose

Patent number: 7742899Abstract: A method of determining steering rack rattle propensity of a rack and pinion steering assembly may comprise: simultaneously recording audio, and measuring acceleration of a rack, and right and left side tie-rod end loads; identifying rack rattle events from the audio recording; determining common characteristics of the measured rack acceleration and tie-rod end loads during the identified rack rattle events; creating a rack rattle index level; applying a predetermined force profile to a test rack and pinion steering assembly; measuring a test acceleration on the test rack and pinion steering assembly; calculating a test RMS level in a test frequency range using a test time constant; determining a rack rattle index value from the calculated test RMS level; and comparing the rack rattle index value to the rack rattle index level.Type: GrantFiled: February 12, 2008Date of Patent: June 22, 2010Assignee: GM Global Technology Operations, Inc.Inventors: Charles J. Lemont, Jr., Jose M. Lopez, David C. Pomerville, Scott R. Kloess, Robert S. Brines, Marc J. Tahnoose, Darrin S. Mallard
