The preferred embodiments of the present invention provide a method and apparatus for generic data conversion. A method in accordance with the present invention comprises coarsely pointing the reflector to an orbital slot used in the satellite configuration, wherein at least one satellite in the orbital slot transmits first circularly polarized signals, and adjusting the reflector to maximize reception of the first circularly polarized signals from the orbital slot. At least one measure of the complexity of the EEG signal data is derived from the data. The particles may be configured to produce a signal when a receptor coupled to the particle interacts with the analyte. The heat-radiation film is formed between a substrate and the magnetic film and is formed of a plurality of alloy films having different thermal conductivities.
