Abstract: A weld inspection system is adapted to inspect a weld of a work product via thermographic technology. The weld inspection system includes a heat source assembly, a thermal imaging camera, and a controller. The heat source assembly is adapted to sequentially direct a plurality of heat pulses upon the work product from varying perspectives and within a pre-determined time period. Thea thermal imaging camera is configured to thermally image the weld over the pre-determined time period and collect thermal imaging data of heat dissipation from the work product. The thermal imaging data is associated with the weld and the plurality of heat pulses. The controller is configured to control the heat source assembly and the thermal imaging camera. The controller includes a processor configured to receive and transform the thermal imaging data into a binary image for evaluation of the weld.

Abstract: A stack assembly having a battery tab with a localized weld and method of making the same is disclosed. The assembly is made by a process including the steps of arranging a plurality of battery tabs into a stack assembly; providing a resistive coating on at least one of the interior surfaces and the exterior surfaces of the battery tabs; and resistive heating the stack assembly. The resistive coating is a nickel-phosphorous (Ni—P) alloy containing 5 to 7 weight percent phosphorus. Resistive heating includes reacting the Ni—P alloy with an electric current to generate concentrated heat localized between adjacent battery tabs such that the Ni—P alloy undergoes solid-state bonding with the Cu in the first batter tab.

Abstract: A functionalized adhesive and systems and methods employing the same are disclosed. The functionalized adhesive is configured to form an adhesive joint between a first substrate and a second substrate. The functionalized adhesive comprises a neat adhesive selected to have a bonding strength above a predetermined bonding threshold and a filler selectively dispersed within the neat adhesive. The filler is selected to modify electrical properties of the neat adhesive such that the functionalized adhesive is electrically conductive with a tailored resistivity and such that a resistance of the adhesive joint is greater than a resistance of the first substrate and the second substrate.

Abstract: A transmission range selection sensor includes a housing defining a bore extending along a central axis. A piston is slideably disposed within the bore. A magnet carrier is attached to and moveable with the piston. A magnet is supported by and moveable with the magnet carrier. A first magnetic sensor and a second magnetic sensor are supported by the housing and are spaced from each other along the central axis. A position of the magnet carrier along the central axis is determinable from a sensed magnetic flux from the first and second magnetic sensors. The sensor includes at least one magnetic flux concentrator attached to one of the magnet carrier or the housing. The flux concentrator is operable to concentrate the magnetic flux toward at least one of the first magnetic sensor or the second magnetic sensor depending upon a position of the magnet along the central axis.

Abstract: A method of analyzing the quality of a battery cell includes performing a high-throughput quality check on the battery cell with a quality control system, assessing a quality score to the battery cell, with quality score identifying the battery cell as low-quality or high-quality, and performing a comprehensive quality check on the battery cell if identified as low-quality. The method further includes assessing an enhanced quality score to the battery cell superseding the quality score of the quality control system identifying the battery cell as confirmed low-quality or confirmed high-quality and providing revised production instructions for manufacturing successive battery cells if confirmed low-quality.

Abstract: A method of forming a separator for a lithium-ion battery includes arranging a polymer film in contact with a sacrificial layer to form a cutting stack. The method includes disposing the cutting stack between a first vitreous substrate and a second vitreous substrate. The method includes applying an infrared laser to the cutting stack through the first vitreous substrate to generate heat at the sacrificial layer. The method also includes transferring heat from the sacrificial layer to the polymer film to thereby cut out a portion of the polymer film and form the separator. A method of cutting a polymer film and a cutting system are also explained.

Abstract: An electronic transmission range selection (ETRS) system for a motor vehicle transmission includes an ETRS housing disposed on the transmission, the ETRS housing having a magnetic field sensor in communication with a transmission controller; and a magnetic field source including a magnet component and a high magnetic permeability component. The magnetic field source disposed on a transmission selector shaft, the magnetic field source detectable by the magnetic field sensor at a plurality of predetermined positions along a movement path of the transmission selector shaft; and the magnetic field sensor detecting magnetic flux generated by the magnetic field source, and communicating magnetic field source position information to the controller. The high magnetic permeability component homogenizes the magnetic flux generated by the magnet component and the controller generates an electronic transmission mode signal based on the magnetic field source position information.

Abstract: A method of forming a rotor includes isolating a bridge area of an electrical steel lamination. The bridge area is disposed between a first portion of the electrical steel lamination and a second portion of the electrical steel lamination that is adjacent to the first portion. Each of the first portion, the second portion, and the bridge area has an initial hardness, and the electrical steel lamination has an initial magnetic permeability. After isolating, the method includes hardening only the bridge area so that the bridge area has a treated hardness that is greater than the initial hardness. Concurrent to hardening, the method includes decreasing the initial magnetic permeability at only the bridge area.
