Abstract: A method for infiltrating a substance into a heterogeneous solid of a material of an elastomeric strap to form a logo that includes providing a permeating substance and a heterogeneous solid of the elastomeric strap. The heterogeneous solid comprises a first region, a second region, and an interface region interposed between the first region and the second region. The method also includes applying an energy to the heterogeneous solid with the energy of an amount sufficient to render the interface region temporarily permeable; applying a driving force configured to infiltrate the permeating substance into the interface region to form the logo; and, modifying the application of the energy, thereby rendering the interface region impermeable and causing a portion of the permeating substance to disperse into the first region.

Abstract: A flexible, stretchable, and adjustable strap that is designed to be used with most commercially available smartphone cases to assist the user in holding and using their smartphone is provided. This strap is easily installed on and removed from such cases in minutes, without adhesive, modifications to the case, or any structure permanently attaching the strap to the case, allowing the user to use the same strap on a different case or to change straps without the need to purchase a new case. The strap, consisting of a stretchy/elastic material with hook and loop fasteners on each end that enable connection to form a loop through the existing ports on the case, is positioned to lie flat and tight against the back of the case and may be stretched from this resting position to accommodate the user's fingers, hand or other objects to steadily hold the cased smartphone.
