Problem: To suppress the occurrence of damage to fuel cell units caused by oxidation shrinkage of fuel electrodes. Electrode combination parameters that support cardiac function consistent with a prescribed therapy are evaluated for each of a plurality of electrode combinations. The method may further include generating Doppler spectrum data or Doppler sound based on the data of the filled I and Q component signals. The reference signal may be generated by a signal generator within the base station; by a mobile station hardwired to the base station; or by a mobile station proximate the base station, sending the reference signal over the air interface. A VIVR session can coordinate the delivery of visual information and the delivery of telephony-based information such that the user hears an audible message on the telephone that corresponds to the information displayed on a networking device. Ideally, the same metal as the metal which is deposited is used for constituting the counter electrodes.
