    Abstract: An articulating joint includes a linkage and a pin. The linkage includes a surface defining an opening. The pin extends along a pivot axis, and is disposed, at least in-part, in the hole. The pin has a core component made of a first material, and an outer component that at least partially circumferentially surrounds the core component and is made of a wear resistant material. The outer component includes a gradated sub-surface depth extending in a radial direction.

    Abstract: A wastegate actuator assembly includes a regulating rod, an arm, and a shaft. The regulating rod includes a proximate end region and a distal end region wherein the proximate end region of the regulating rod may be connected to an actuator. The arm includes a first end region and a second end region. The first end region is pivotally coupled to the distal end region of the regulating rod via a crank pin, a first cup spring, and a second cup spring wherein the first and second cup springs retain a solid lubricant substantially around the crank pin. The regulating rod may move in a linear fashion causing the arm and the shaft to rotate so as to move a wastegate cover connected to the shaft from a closed wastegate duct position (toward the wastegate duct) to an open wastegate duct position (away from the wastegate duct).

    Abstract: Presented are electrochemical devices with in-stack reference electrodes, methods for making/using such devices, and battery cells with stacked electrodes segregated by electrode separator assemblies having built-in reference electrodes. An electrochemical device includes a protective outer housing that contains an ion-conducting electrolyte. A stack of working electrodes is packaged inside the device housing in electrochemical contact with the electrolyte. At least one electrode separator assembly is located inside the housing, interposed between a neighboring pair of these working electrodes. The electrode separator assembly includes an electrically insulating separator sheet with a reference electrode. A tab pocket, which projects from an end of the separator sheet, includes a tab chamber with a chamber opening. An electrode tab is formed with an electrically conductive material and attached to the tab pocket. One end of the electrode tab is disposed in the tab chamber and the other end projects out from the chamber opening.

    Abstract: A solid-state battery cell includes an anode electrode comprising an anode current collector and an anode coating. A cathode electrode comprises a cathode current collector and a cathode coating, wherein the anode electrode and the cathode electrode exchange lithium ions. A separator layer is arranged between the anode electrode and the cathode electrode. A first capacitor electrode is arranged at least one of between the anode coating and a first side of the separator layer, between the anode coating and the anode current collector, between a second side of the separator layer and the cathode coating, and between the cathode coating and the cathode current collector.
