The subject invention concerns platinum complexes that exhibit antitumor cell andor antiparasitic activity. In one embodiment, the launch monitor is capable of being transported and used in any desired location. The FET M21 constitutes a current bleeding circuitry and the other components except for the two inductors L1 and L2 constitute a so-called Gilbert cell mixer. The process and system preferably uses a special sulfur tolerant catalysts and hardware designs that enable the conversion in an energy efficient manner while maintaining desirable performance characteristics such as rapid start-stop and fast response to load change capabilities. The circuitry is further configured to block a flow of electrical current from any one of the storage devices to any of the other storage devices, thereby avoiding flow of currents that could otherwise circulate among the electrical energy storage devices due to electrical imbalances that may occur in one or more of the electrical energy storage devices.
