An apparatus for generating a data structure containing at least one field corresponding to a setting of a product includes a memory storing a plurality of queries corresponding to various configuration settings of the product. The first electrode and the second electrode provide for capacitive drive of the resonator body and capacitive sense of the resonator body. A state manager includes a plurality of states, wherein a state includes a second list of a subset of objects of the plurality of objects and determines a display appearance and a display action of the subset of objects. Based on this reason, appropriate error resolution and recovery operations are performed and the transaction is resubmitted only to those software resources that were unable to commit. The invention also relates to a method for tapping signals of the electric potential of the heart and the pulse value and applying saved frequency information by means of a device according to the invention.
