A retention arrangement for a circuit interrupter to ensure that ensures the retention of the circuit interrupter in its mounting. The heat conducting member includes a heat absorbing section contacting with the first heat sink, and first and second heat dissipating sections extending inwards from upper ends of first and second connecting sections extending upwardly from two ends of the heat absorbing section, respectively. higher than the release temperature of the thermal release adhesive tape so that the thermal release adhesive tape with the bottom graphene layer can be removed, obtaining a metal foil with a top graphene layer sample, andtransferring the top graphene layer onto a substrate via a sacrificial protective layer. Some embodiments include transferring the appropriate data to temporary latchesregisters, in preparation for programming, concurrently with the evaluation of whether to program or skip the programming. These methods can further involve identifying other bank cards used at the common point of compromise. The clip and fastener preferably are bioabsorbable.
