Patent number: 10955880Abstract: An electronic device has a foldable display. First and second portions of an electronic device housing for the device may be joined using a hinge. A flexible display may overlap the first housing portion and the second housing portion and may bend along a bend axis as the first and second housing portions are rotated relative to each other using the hinge. The hinge may include toothed members such as gears and a rack member. The rack member may have a surface with curved portions. The gears may include rotating gears that walk along the curved portions of the rack member as the electronic device is folded and unfolded.

Patent number: 9844809Abstract: A forming tool stamps sheet metal blanks into a desired shape. A contoured surface is defined for the forming tool so that respective portions of the metal blank flow over the contoured surface during forming. An intrinsic material flow pattern resulting from the contoured surface is compared to a desired flow in order to identify regions of the contoured surface having an insufficient flow that creates areas in the formed metal blank receiving less than a desired amount of metal. A surface microtexture is applied onto the contoured surface in a pattern selected to increase metal flow along the identified regions by providing a coefficient of friction in the identified regions that is reduced relative to adjacent regions of the contoured surface.Type: GrantFiled: March 22, 2016Date of Patent: December 19, 2017Assignees: FORD GLOBAL TECHNOLOGIES, LLC, THE BOEING COMPANY, NORTHWESTERN UNIVERSITYInventors: Zhiyong Cedric Xia, Jian Cao, Qian Wang, Rajesh Talwar, Donald J.

Patent number: 8831914Abstract: The stamping of a metal sheet within a stamping die is simulated. The die includes a drawbead running perpendicular to a draw direction. A plurality of successive states are generated for iteratively representing the metal sheet from a blank shape to a final stamped shape. The drawbead is represented as a two-dimensional flat band within a model of the stamping die. Forces acting on the metal sheet are calculated at each successive state to define a next successive state. The calculating step includes a restraining force of the drawbead acting on the metal sheet calculated in response to a predetermined function of a length of the metal sheet engaged in the flat band in respective states. The particular width and location of the flat band achieve improved accuracy of estimating the restraining force.Type: GrantFiled: April 4, 2012Date of Patent: September 9, 2014Assignee: Ford Global Technologies, LLCInventors: Yinong Shen, Feng Ren, Zhiyong Cedric Xia

Patent number: 8706282Abstract: In one or more embodiments, a weldability of a stack-up for use in vehicle part production may be determined. The determination may include receiving general stack-up information, welding standards data for forming a stack-up, and one or more inputs defining one or more stack-up design variables. Additionally, standardized stack-up information may be generated based on the general stack-up information, the one or more design variables, and the welding standards data. Furthermore, historical welding data may be received for predicting a weldability of the stack-up. Predictive logic may be applied to the standardized stack-up information based on the historical welding data to obtain one or more weldability predictions for the stack-up. The one or more weldability predictions may be transmitted for use in vehicle part production.Type: GrantFiled: January 12, 2010Date of Patent: April 22, 2014Assignee: Ford Global Technologies, LLCInventors: Raja Shekar Sohmshetty, Theodore Coon, Saravanan Subramanian, Zhiyong Cedric Xia
