The present invention discloses a modified computer architecture which enables an applications program to be run simultaneously on a plurality of computers. A temperature condition of a readwrite head in a storage device is ascertained and it is determined whether the temperature condition is within a predetermined range of temperature conditions in which the readwrite head exhibits instability. The one or more radio head interface modules adapted to communicate with the call processing software module, wherein the call processing software performs modulation and demodulation of voice and data streams using one or more air interface protocols. The stowage bin may be integrated into the craft. A further advantage of the compressible bolt carrier extension system is the reduction of felt recoil as the system fully loads during the recoil stroke as it pushes against the buffer absorbing additional recoil energy. An optical device such as a lens or mirror provides a Fourier transform of image information from the image production device onto the image capture device.
