A technique for handling hardware errors in a computing system, such as a data storage facility, while avoiding a system crash. A locking element carrier extends in the circumferential direction around the rotational axis and comes at least one first locking element which extends away from this carrier toward the first element in a first circumferential direction. In one embodiment, patterning may be performed within microfluidic channels by flowing a solution of crosslinking agent that can crosslink a portion of an ionotropic polymer in contact with the solution. In response to a query from a client, at least a portion of the stored detected events is stored. An action script is then executed based at least partially on the matching template which may include the contacting of a responding party.
