Abstract: Generally described, one or more aspects of the present disclosure relate to methods, systems, and devices related to forming a wound electrode assembly including a hemmed electrode and a separator, the hemmed electrode including an electrode film and a foil. The foil can include a core edge, a can edge, and a hemmed edge disposed between the core and can edges and extending from the core edge to the can edge. The electrode film can be disposed over the foil and the hemmed edge can extend beyond a top edge of the electrode film. The hemmed electrode can be wound to form a wound hemmed electrode assembly.

Abstract: Coupling devices useful for fluidly connecting components of products, such as vehicle coolant components, are described. The coupling device may be press-fit onto male barb interfaces and thereby create a robust and durable liquid-tight seal, and may allow for autonomous factory installation. The coupling device may include an internal material, an external material, flared ends connected by a cylindrical intermediary portion and a hollow interior portion, wherein a hardness of the internal material is less than a hardness of the external material.

Abstract: Coupling devices (100) useful for fluidly connecting components of products, such as vehicle coolant components, are described. The coupling device may be press-fit onto male barb interfaces and thereby create a robust and durable liquid-tight seal, and may allow for autonomous factory installation. The coupling device may include an internal material (102), an external material (104), flared ends (106) connected by a cylindrical intermediary portion (108) and a hollow interior portion (110), wherein a hardness of the internal material is less than a hardness of the external material.

Abstract: An integrated, unitary battery pack may be formed and used as part of the structural support for a vehicle frame. The unitary battery pack includes arrays cells having all positive and negative electrical terminals aligned in-plane on a common face of the product assembly. The unitary battery pack includes cooling components for passively or actively cooling the cell arrays. The unitary battery pack is encased in a potting material that allows that forms part of the structure support for the unitary battery pack. The unitary batter pack may be integrated into the vehicle with or without additional support structures.

Abstract: A foldaway stepping stool apparatus includes a backplate attachable to a cabinet and a stepping stool mountable onto the backplate. The stepping stool is configurable into deployed and folded configurations. The stepping stool includes a platform, a pivotable front leg, a pivotable rear leg, a latch, and a bracket coupling the latch and the front leg. The latch operates to lock the stepping stool in the deployed configuration and to secure and free the bracket, enabling movement of the stepping stool between the deployed and folded configurations. The backplate includes a track for removably receiving the stepping stool. The track enables the stepping stool to slide in and out thereof to attach and detach, respectively, for use at the cabinet or away from the cabinet. The track further enables the stepping stool to slide therethrough to contact a floor to support the cabinet while the apparatus is mounted thereon.

Abstract: A system for incorporating one or more individual energy cells is provided. Individual energy cells include a top surface having a center terminal and an outer terminal. The first terminal and the second terminal are configured as substantially planar electrical contacts. The cell further includes a side surface mechanically connected to the top surface and a bottom surface mechanically connected to the side surface.

Abstract: A combination hair tie and face mask assembly includes a mask panel and hair tie members for transforming the assembly between a face mask and hair tie. The mask panel includes longitudinal and lateral edges and a mask covering that spans between the edges. The hair tie members are attached to the mask panel and include a tie covering having a first end and second end separated by a gap, a cannula extending between the first end and second end, and a tie elastic that is formed into a closed loop through the cannula and exposed at the gap. The assembly is transformable into a face mask by drawing the tie elastics from the hair tie members to create an ear loop that can be donned around a user's ears and to exert tension on the face covering such that it can be donned over the user's mouth and nose.
