Abstract: Battery contact with surface texturing. Exemplary battery contacts are located within a battery pack. The battery pack is operable to provide power to a device through a device contact of the device. The battery pack includes a battery pack housing, at least one battery cell located within the battery pack housing, and battery contacts including a positive terminal and a negative terminal. The battery contacts are configured to engage the device contact of the device and allow electric current to transfer from the battery pack to the device. The battery contacts define a surface having a surface texture. The surface texture includes raised portions for contacting the device contact to allow electric current to transfer from the battery pack to the device. The surface texture also includes recessed regions spaced away from the surface and for providing a space between the battery contacts and the device contact.

Abstract: Structures and methods applicable, for example, to apparel and accessories. Such a structure might, for instance, include a layer imparting rigidity. A layer might, for example, be situated above the layer imparting rigidity. Alternately or additionally a layer might, for instance, be situated below the layer imparting rigidity. Situated within one or more discontinuities might, for example, be one or more magnets. One or more platforms might, for instance, be situated above such a layer situated above the layer imparting rigidity. Alternately or additionally one or more platforms might, for example, be situated below such a layer situated below the layer imparting rigidity. One or more items placed on one or more of the platforms might, for instance, be attracted to one or more of the magnets.
