Patent number: 9573320Abstract: A method, for repairing a discrepant weld in a workpiece arrangement including at least two workpieces, comprising positioning a mechanical intermediary adjacent the discrepant weld and inserting the intermediary through the discrepant weld and into at least a distal workpiece of the two workpieces, wherein upon insertion, a proximate surface of the intermediary is exposed at a proximate side of the workpiece arrangement. The method further includes delivering weld energy to the intermediary. The intermediary is configured, and the weld energy provided, so that energy passes through the intermediary in a pre-determined manner. Energy passing through the intermediary in the pre-determined manner generates heat in material of the workpieces causing the material to melt at an arrangement interface. The method further comprises allowing or causing the material melted to cool, wherein the melted material, when cooled, forms and/or strengthens a robust joint connecting the workpieces.Type: GrantFiled: September 3, 2014Date of Patent: February 21, 2017Assignee: GM Global Technology Operations LLCInventor: Pei-Chung Wang

Patent number: 9573194Abstract: Spherical particles of one or more elemental metals and elemental carbon are prepared from a precursor in the form of a metal oleate. The metal oleate precursor is dispersed in a liquid vehicle and aerosol droplets of the dispersed precursor are formed in a stream of an inert gas. The aerosol droplets are heated in the stream to decompose the oleate ligand portion of the precursor and form spherical particles that have a mesoporous nanocrystalline structure. The open mesopores of the spherical particles provide a high surface area for contact with fluids in many applications. For example, the mesopores can be infiltrated with a hydrogen absorbing material, such as magnesium hydride, in order to increase the hydrogen storage capacity of the particles.Type: GrantFiled: August 22, 2014Date of Patent: February 21, 2017Assignees: GM Global Technology Operations LLC, The Regents of the University of CaliforniaInventors: Qiangfeng Xiao, Mei Cai, Hiesang Sohn, Yunfeng Lu

Patent number: 9573476Abstract: A method and system for waking up a primary microcontroller of a controller in response to a change in a control pilot signal generated by an external device coupled to the controller includes coupling the external device to an input port electrically connected to the controller. A control pilot signal generated by the external device is received by the input port and outputted to a monitoring device of the controller in low power mode. The monitoring device in low power mode polls the control pilot signal and upon detecting a valid change transitions to normal power mode to output a wakeup pulse to the primary microcontroller, which in a sleep state receives the wakeup pulse and wakes up to execute instructions stored on the primary microcontroller. In an example, the system controls recharging of a battery by a charging station which outputs a pulse width modulated control pilot signal.Type: GrantFiled: June 9, 2014Date of Patent: February 21, 2017Assignee: GM Global Technology Operations LLCInventors: Thomas John Timpf, Jr., Cody D.

Patent number: 9576352Abstract: A quantitative metallographic method to measure skin layer thickness in high pressure die cast aluminum components. Because the faster-cooling skin layer region exhibits a higher volume fraction of eutectic phases than that of a slower-cooling inner region, measurements showing such higher eutectic phases can be used to quantify such layer thickness. An image at various thicknesses of a location of interest in a cast component sample is first obtained using an image analyzer, from which eutectic volume fractions within each of the received images may be determined. Comparisons of the determined volume fractions can be made against a known or predicted quantity for a particular alloy composition, and then correlated to the skin layer thickness via differences between the received or measured quantities and those of the known standard.Type: GrantFiled: April 15, 2014Date of Patent: February 21, 2017Assignee: GM Global Technology Operations, LLCInventors: Qigui Wang, Wenying Yang, James W.
