A Medical Device Application (MDA) is disclosed for an external device (e.g., a cell phone) that can communicate with an Implantable Medical Device (IMD). The MDA receives data logged in the IMD, processes that data in manners reviewable by an IMD patient, and that can control the IMD based on such processed data. The MDA can use the logged data to adjust IMD therapy based on patient activity or posture, and allows a patient to learn optimal therapy settings for particular activities. The MDA can also use the logged data to allow a patient to review details about IMD battery performance, whether such battery is primary or rechargeable, and to control stimulation parameters based on that performance. The MDA also allows a patient to enter medicine dose information, to review the relationship between medicinal therapy and IMD therapy, and to adjust IMD therapy based on the dosing information.

An object provides a power generation apparatus performing the purification of an Al alloy melt using scrap as raw material. A power generation apparatus includes: a container body with aluminum alloy melt and molten salt in a liquid junction with the aluminum alloy melt; an anode which is in contact with the aluminum alloy melt; and a cathode which is in contact with the molten salt. DC power is obtained from between the anode and the cathode by an anode reaction on the aluminum alloy melt side and a cathode reaction on the molten salt side. When the aluminum alloy melt and the molten salt are separated by a separator allowing ionic conduction between the aluminum alloy melt and molten salt, the power generation efficiency is enhanced. The amount of a reactant in the Al alloy melt is monitored by measuring the electrical quantity associated with the power generation.
