Abstract: The invention relates to a shoe (1), in particular a sports shoe, having an upper (2) and a sole (3) connected to said upper (2). In order to achieve good resilience properties of the sole of the shoe together with excellent wearing comfort, at least some areas of the sole (3) consist of a number of hollow bodies (4) embedded in a carrier material (5), wherein said carrier material (5) consists of a foamed plastic material.

Abstract: The invention relates to a method for producing a shoe (1), comprising a shoe sole (2) and an upper (3).

Abstract: An article of footwear is provided that includes a sole structure and an upper attached to the sole structure. The upper includes an exterior layer and a base layer, and the exterior layer includes a biodegradable layer and a biologically active agent capable of biodegrading the biodegradable layer.

Abstract: A shoe includes a sole structure that defines a first supporting structure, a second supporting structure, and a third supporting structure, the first supporting structure being disposed within a forefoot region, the second supporting structure being disposed within a midfoot region, and the third supporting structure being disposed within a heel region. Each of the first supporting structure, the second supporting structure, and the third supporting structure define at least one curved surface, against which a plurality of plastic bodies are disposed. The plurality of plastic bodies comprise foamed plastic, define spheres or ellipsoids, are between 1 mm and 13 mm in the three spatial directions, and are arranged loosely within the sole structure without connection to one another. The plurality of plastic bodies are compressed against the first supporting structure, the second supporting structure, and the third supporting structure.

Abstract: The invention relates to a method for producing a shoe (1), comprising a shoe sole (2) and an upper (3).

Abstract: A method for producing a shoe sole. To be able to produce the shoe sole in an economical fashion and with easily selectable spring and damping characteristics, the invention has the following steps: a) extruding a plastic hose and feeding the plastic hose into a blow mold; b) blow molding the plastic hose into a sole hollow body, wherein recesses are introduced on mutually opposing walls of the sole hollow body during the blow molding process, such that parts of the walls are brought into contact with one another and form a supporting structure between the mutually opposing walls; c) removing the blow-molded sole hollow body from the blow mold; d) at least partially filling the blow-molded sole hollow body with plastic bodies, wherein the plastic bodies are added through a first opening in the sole hollow body.

Abstract: A charging device and a method for charging an electrical energy storage device of a vehicle, with a DC converter for converting an input DC voltage into an output DC voltage. A winding of an electrical machine is part of the DC converter. The winding has at least two coils. A control unit is designed for the purpose of switching the at least two coils electrically in series for the charging of the electrical energy storage device. The at least two coils form an inductance of the DC converter.

Abstract: Packaging that includes a first layer of bubbles, wherein each of the bubbles comprises an outer shell that defines an interior cavity, and a first element and a second, different element provided within the interior cavity of at least one bubble. The at least one bubble is configured to inflate or degrade over time.

Abstract: An article of footwear is provided that includes an insole member. The insole member includes a base layer, an intermediate layer having a plurality of cavities, and a microbial layer having a plurality of microbial mediums with one or more microorganisms therein. Further, the cavities receive the microbial mediums of the microbial layer.

Abstract: A bioindicator assembly for determining a level of CO2 in a surrounding environment includes an article and a bioindicator component applied to the article. The bioindicator component includes a composite fabric that has a substrate, wherein a biodegradable material is applied to the substrate, a membrane that is coupled with the composite fabric to define an interior cavity, the membrane being semi-permeable, a bioindicator that changes color, form, shape, or texture when exposed to CO2, and an attachment mechanism coupled to a rear side of the composite fabric.

Abstract: A drive device, having a first electric machine operable as a generator and a second electric machine operable as a motor, which are electrically connected to one another, so that the second electric machine is operable using electric energy provided by the first electric machine, wherein an energy accumulator for temporarily storing electric energy is electrically connected to the first electric machine and the second electric machine. It is provided in this case that the first electric machine and the second electric machine are electrically directly connected to one another via an intermediate circuit, wherein the energy accumulator is electrically connected to the intermediate circuit via a switch arrangement both directly and also indirectly via a voltage converter. The disclosure furthermore relates to a method for operating a drive device.
