A spark plug configured such that a noble-metal tip is welded to each of a front end portion of a center electrode and a distal end portion of a ground electrode. Polytetrafluoroethylene film is suited as material for the band. A similarity function indicative of a likelihood that the first and second image datasets are in correspondence with one another is computed by a processor and then a ranking of each of a plurality of local maxima of the similarity function is determined. The invention further relates to a method for operating such a device. A customer may create an account on a provisioning system and manage the account options within a provisioning system which facilitates activity within an existing carrier provisioning system architecture.
