Provided is a method for the synthesis of an aralkyloxyadenosine or an alkoxyadenosine. The first device receives linking information from said second device and provides that information to the third device. In an aspect, the variably engageable coupling may include a biasing mechanism and a coupling member, wherein the biasing mechanism automatically resets or releases upon reaching a force or tension threshold. Further, embodiments of the present invention may initialize the cache memory to a specified pattern.
