In one embodiment of the present invention, a computer-implemented method includes receiving a set of alphanumeric information on a single storage device. One example embodiment comprises establishing a secure connection to a network requiring access credentials, detecting a content source, establishing a non-secure connection to receive image data from the content source, receiving the image data from the content source, and providing the image data to a display, wherein the content source is not provided access over the secure connection. The process is characterized in that the milling apparatus is followed by a control sieving facility, with the sieve opening being selected so that essentially 100% of the brown coal passes the sieve. The second chassis sidewall defines a second ventilation hole. The system also includes a computer which is connected to the host controller for control of desired signal outputs to the speakers as well as desired signal inputs to the host controller.
