Abstract: The invention describes system and method for generation a derivative document from a patent document, which provide value, enhanced representation of the document and facilitate comprehension of information contained in the patent document. A segment of the patent document is selected and transformed into a value added dorm by extracting at least two portions of information from the selected segment and converting them into different forms. Conveniently, the converted forms include respective elements where the required correspondence is established between the elements. Depending on customer needs and requirements to the system, a customized selection of the elements can be provided with optional display, storage and/or delivery of the selected data over a network. Beneficially, generation of the derivative is performed by using distributed processing of the document in a network, where two or more computers are involved. Corresponding method of generation a database of the derivative documents is also provided.

Abstract: An apparatus for separating fibrous material such as wool, wood, paper, cellulose, rockwool, fiberglass, etc., which is conveyed by and suspended in air. The separator can be used with pneumatic vacuum systems and pneumatic pressure conveying systems for separating fibrous material used for insulation. The apparatus includes a housing having an inlet, an air outlet and a fibers outlet. An air lock is provided at the fibers outlet for allowing fibrous material to exit but generally restricting the air from exiting therethrough. A screen supported on a support fixture located at the air outlet allows air to pass but generally restricts fibrous material from exiting. The fibrous material is allowed to accumulate on the screen thereby forming a fibrous filter mat for filtering smaller fibrous particles.  Scalping blades travel over and at a distance from the screen thereby removing accumulated fibrous material and retaining the fibrous filter mat at a desired thickness for allowing air to pass but filtering smaller fibrous particles. The distance between the screen and scalping blades is selectively adjustable by selectively moving the screen for thereby selectively adjusting the thickness of the filter mat. A pressure transducer senses the differential pressure between the housing and the air outlet and increases the thickness of the filter mat in response to decreasing pressure differential and decreases the thickness of the filter mat in response to increasing differential pressure.

Abstract: A signalling method in a wireless digital telecommunication system, where the signals between a base station and a terminal comprise bursts generated from symbols. The symbols comprise at least one stealing symbol indicating, if necessary, the use of a traffic channel for signalling. The symbols are generated from several bits by modulating and the stealing symbol is used for transmitting various signalling messages. A signalling message to be transferred is coded into a code word which is placed into one or more stealing symbols. The code word may be interleaved into the stealing symbols of several bursts. The method can be used, for example, for controlling the transmission power of the mobile station and the base station.

Abstract: A method and device for gating the transmission of dedicated control channels in a CDMA communication system is disclosed. In the device and method, if a base station (mobile station) determines whether there is no data to transmit to a mobile station (base station) for predetermined period of time, the base station (mobile station) gates transmission of control information according to a predetermined pattern on a dedicated control channel, which is used for transmitting control information to the mobile station (base station). Control information transmitted from the base station to the mobile station includes Transport Format Combination Indicator (TFCI), Transmit Power Control (TPC), and a pilot symbol. Control information transmitted from the mobile station to the base station includes TFCI, TPC, a pilot symbol, and FeedBack Information (FBI) for information about a transmit diversity antenna system. In a downlink DPCCH, transmission of the TFCI, TPC and pilot symbol of the predetermined n slots out of total slots of frame can be transmitted discontinuously during gated transmission. Alternatively, transmission of a pilot symbol of the predetermined nth slots and TFCI and TPC of (n+1)th slots can be transmitted discontinuously. In an uplink DPCCH, transmission of all the TFCI, TPC, FBI and pilot symbol of a specific slot are transmitted discontinuously during gated transmission. In addition, transmission of TPC for power control can be continuously transmitted for full rate power control when the traffic data is for transmission.
