Abstract: Various marking apparatuses are provided that incorporate a soluble component and a marking component. The soluble component dissolves in the presence of a solute and the marking component is left as a residue that can be used, for example, to designate a boundary for a recreational activity. In one example, the marking apparatus may be a marking tape that can be utilized to apply a temporary mark on a surface. The marking tape can be affixed to the surface by, for example, inserting a stake through one or more apertures of the marking tape. The user may also utilize measurement guides provided on the marking tape to accurately measure distances without the use of extra equipment. When exposed to a solute such as water, the soluble component of the marking tape dissolves and leaves behind the marking component. Both the soluble component and the marking component may be biodegradable and the marking tape may require little to no upkeep after deployment.

Abstract: A method for dynamically (i.e., upon boot) rewriting, in a failure resistant manner, of part of, or the entirety of, the flash memory for a device allows for a changing of location for logical blocks of execute-in-place code. Conveniently, the rewriting results in a randomization, of varying degree, of the address space layout upon each boot up cycle.
