Patent number: 10713867Abstract: A method and system for predicting, detecting, and storing vehicle dynamics information. The method comprises receiving a series of consecutive signals indicating speed of a vehicle and additional data associated with the signals over a vehicle bus for a configurable period of time, comparing the consecutive speed signal with the previous speed signal to identify deceleration and acceleration of the vehicle, calculating a deceleration rate based on the sum of decelerations and accelerations, and storing the signals and additional data associated with the signals in a vehicle memory when the calculated deceleration rate is greater than or equal to a configurable event detection threshold deceleration rate. This configuration does not require the use of vehicle sensors, but instead utilizes pre-existing vehicle infrastructure, which allows for more precise analysis of vehicle dynamics information during an event like a collision, for all vehicles, in a cost-effective manner.Type: GrantFiled: April 24, 2018Date of Patent: July 14, 2020Assignee: Flex, Ltd.Inventors: Sandor Zsombory, Behnam Rezvannia

Patent number: 10687421Abstract: A conductive fabric includes a fabric with one or more electrically conductive wire braids woven into the fabric. The one or more wire braids are woven into the fabric such that one or more portions of each wire braid are exposed at one or more surfaces of the fabric, the exposed portions of the wire braid forming connection pads. Each connection pad provides an electrical connection point for attachment to a complementary electrical connection point on an electronic component, such as a bond pad, solder bump, or connection lead. A single wire braid can be used to electrically interconnect multiple electronic components. Multiple wire braids can be arranged, with appropriate spacing and alignment of exposed portions, to electrically interconnect multiple electronic components with multiple electrical interconnects between one or more electronic components. Each electrically conductive wire braid includes a plurality of individual electrically conductive wires braided together.Type: GrantFiled: April 4, 2018Date of Patent: June 16, 2020Assignee: Flex Ltd.Inventors: Weifeng Liu, William Uy, Jie Lian, Zhen Feng, Robert Pennings, Anwar Mohammed, Murad Kurwa

Patent number: 10650946Abstract: A circuit and method provide improved trimming of a DCR sensing circuit where a sensing element is sensitive to self-heating or having a large tolerance. The circuit includes a resistive divider circuit coupled to a sensing element. The resistive divider circuit includes a trim resistor and two test points. Prior to trimming the trim resistor, an actual resistance of the sensing element is determined. A target voltage across the trim resistor to be trimmed is calculated according to the determined sensing element resistance and a known small trim current that is to be injected into the circuit during the trimming process. This injected trim current has a low current value so there is no self-heating of the sensing element. Then, the trim resistor is trimmed while injecting this small trim current into the resistive divider circuit and the voltage across the trim resistor is monitored.Type: GrantFiled: August 8, 2018Date of Patent: May 12, 2020Assignee: Flex Ltd.Inventors: Mikael Appelberg, Andreas Larsson

Patent number: 10653010Abstract: Attaching electronic components to a substrate can be challenging in certain applications. By utilizing printed conductive ink to fill vias, one or more conductive layers may be provided, which allow for fine pin pitches or other crowded substrates to utilize multiple layers for traces connecting the contact pad to the pins of an electronic component. By applying a substrate with conductive ink and then selectively applying a solderable ink on the conductive ink, and with conductive ink filling the vias, electronic components may be attached to a substrate that provides mechanical attachment and electrical connectivity which may also be formable or flexible.Type: GrantFiled: September 9, 2019Date of Patent: May 12, 2020Assignee: Flex Ltd.Inventors: Weifeng Liu, William L.

Patent number: 10499500Abstract: A metal pallet is integrated within a circuit board using a process similar to a multilayer PCB, which integrates the metal pallet into the circuit board at the same time as the supporting layers are fabricated. The use of B-stage material provides a bonding mechanism for the metal pallet to be embedded within the circuit board, creating a cohesive integrated part. Embedding the pallet during the fabrication process, pre-lamination, generates a more robust construction and connection not impacted by post fabrication process in assembly. After assembly the circuit board with embedded metal pallet can be mounted directly on a heat sink, cool ribbon or other feature required to help remove heat. The planar back side surface provides a more robust mounting of the metal pallet than a post fabricated assembly as used in conventional techniques.Type: GrantFiled: November 3, 2017Date of Patent: December 3, 2019Assignee: Flex Ltd.Inventors: J H Berkel, Todd Robinson, Joan K.
