An adjustment mechanism including a slide positioned between two zipper tapes, an underlayer positioned adjacent the zipper tapes and the slide, and an adjustment control element coupled to the inner portion of the slider and positioned between the zipper tapes and the underlayer and also coupled to a feature of an item to be adjusted. Thus, various embodiments of the present invention provide a memory apparatus that includes a memory block comprising a plurality of memory cells, each memory cell adapted to operate with multi-level signals. Skew mitigation is low latency, low power, low area, noise tolerant and scalable. The Transmitter may be configured via the user interface to allow users seeking to transmit large, high-resolution images to first generate and transmit low-resolution preview images, thereby saving on transmission time and resources. The fruit are suitable for consumption as fresh berries and are also amenable to processing. The balloon loads onto an ureteroscope prior to insertion, rather than through the ureteroscope as do existing balloons.
