Abstract: Processing of baled material includes a bale opening stage, a separation stage, and a decortication stage. The bale opener features a conveyor moving incoming bales toward a toothed extractor with an array of teeth driven on a revolutionary path moving upwardly past the adjacent end of the conveyor to rake through the bale and extract material therefrom. The conveyor tilts upward reduce a working angle between the conveyor and the toothed extractor to urge the shrinking bale toward the moving teeth. A separation stage features multiple sets of vertically stacked, counter-rotating rollers with different characteristics from one set to the next. A decorticator has an external container, an internal drum rotatably supported therein, and an array of teeth on the drum. Driven rotation of the internal drum spins the fibrous stalks around the internal drum and impacts the fibrous stalks against surrounding interior wall surfaces of the external container.

Abstract: Disclosed are a method for identifying a connection, mobile station and base station. The method comprises the steps of: assigning a MS ID to the mobile station when the mobile station enters into the coverage area of the base station; and assigning a connection ID to a connection when the connection is established between the base station and the mobile station. With the proposed solution, the data overhead could be reduced due to short Connection ID instead of 16-bit CID in 802.16e, especially for VoIP traffic. In addition, due to adjustable bit-length of Connection ID, the tuple <MS ID, Connection ID> could flexibly support different numbers of connections while keeping overhead in minimal.
