Disclosed are compositions and a method for amplification of nucleic acid sequences of interest. An illustrative power generation module disposable within the interior space of an implantable medical device includes a module body that defines an interior cavity as well as a flexible diaphragm that spans the interior cavity. The LEDs therein may be overdriven by power for increased light output. The first object type includes non-water-based objects that do not absorb electromagnetic radiation and the second object type includes objects that absorb electromagnetic radiation. The transmitter codes the first parity packets at the physical layer to obtain second parity packets. The system also may include one or more tension members attached diagonally between adjacent compression members to keep the system in the deployed configuration.
