Patent number: 11323155Abstract: A near field communication (NFC) reader module is provided for mounting over a metal panel of a vehicle. A housing of the module is configured to mount adjacent the metal panel. The housing contains a planar array of non-magnetic RF filter elements in the housing proximate to the metal panel. The housing contains a planar antenna coil configured to couple with an external NFC device carried by a user, wherein the array of RF filter elements is disposed between the planar antenna coil and the metal panel to magnetically decouple the planar antenna coil from the metal panel. The housing further contains receiver circuitry configured to decode NFC signals from the external NFC device.Type: GrantFiled: September 15, 2020Date of Patent: May 3, 2022Assignee: FORD GLOBAL TECHNOLOGIES, LLCInventors: Ali Attaran, Nevin Altunyurt, John F.

Patent number: 10622593Abstract: A power module includes a packaging structure having a pair of side-by-side spaced apart busbars, each connected to a corresponding switch. The power module includes a conductive pad, between and electrically isolated from the busbars and the switches, and configured to, responsive to flow of current through the busbars generated by the switches and resulting in power loop magnetic flux between the busbars, generate magnetic flux that partially cancels the power loop magnetic flux.Type: GrantFiled: June 5, 2018Date of Patent: April 14, 2020Assignee: Ford Global Technologies, LLCInventors: Zhuxian Xu, Guangyin Lei, Nevin Altunyurt, Chingchi Chen

Patent number: 10361147Abstract: A power module has upper and lower transistor dies carried by a lead frame assembly. The assembly has a positive DC paddle for the upper die and an AC paddle for the lower die. An upper plate interconnects a second side of the upper die with the AC paddle, and a lower plate interconnects a second side of the lower die with a negative power bar. Current flowing via positive and negative power bars defines a power loop creating a main magnetic flux with a first direction in a central region and a return direction outside the central region. The upper and lower plates have outer edges having respective notches to concentrate respective portions of a return magnetic flux. Each die has a gate pad connected in a gate loop, wherein the gate loops each overlap a respective concentrated return flux thereby enhancing a common source inductance for each transistor.Type: GrantFiled: June 28, 2018Date of Patent: July 23, 2019Assignee: FORD GLOBAL TECHNOLOGIES, LLCInventors: Zhuxian Xu, Nevin Altunyurt, Chingchi Chen

Patent number: 9515031Abstract: In accordance with one aspect of the present description, a transmission line such as a microstrip or stripline transmission line, has stub-shaped projections adapted to compensate simultaneously for both far-end crosstalk (FEXT) induced by inductive coupling between the transmission line and an adjacent transmission line, and also far-end crosstalk induced by inductive coupling between the vertical electrical interconnect at the far end of the transmission line and an adjacent vertical electrical interconnect electrically connected to the adjacent transmission line. In another aspect of the present description, a microstrip transmission line may have multiple stubby line sections having different resistances and impedances to more gradually transition from to the typically low impedance characteristics of vertical interconnects such as the PTH vias and socket connectors. Other aspects are described.Type: GrantFiled: December 29, 2011Date of Patent: December 6, 2016Assignee: INTEL CORPORATIONInventors: Nevin Altunyurt, Kemal Aygun, Kevin J. Doran, Yidnekachew S.
