Techniques and systems for analysis, diagnosis and debugging fabricated hardware designs at a Hardware Description Language level are described. The present invention also relates to a cosmetic treatment process for artificially tanning or browning the skin and to the use of at least one derivative or a mixture of derivatives of 1,7-bisphenyl heptane-3,5-dione of particular structure for improving the coloration andor stability of a self-tanning agent. The invention also relates to a method of manufacturing such a supercapacitor. In embodiments, the feed rod is embedded at a threshold distance inside the reservoir to provide an increased surface area for transfer of a metallic ink suspension. Release of the securing legs captures the coiled portion on the clip. The portable terminal includes a housing disposed beneath a touch screen display, such that the housing is configured to impact the touch screen display in response to a user input impressed by touch on at least a portion of the touch screen display, the housing including at least one magnetic device configured to collide with the housing.
