IPC: H04J11/00
Filed: 2000-06-16
Granted: 2010-06-30
Abstract: An optimized synchronization (SYNCH) symbol sequence to be used in orthogonal frequency division multiplexing (OFDM) transmission systems, is disclosed. The synchronization symbol is constructed using specially designed OFDM symbols with an optimized sequence, which is mapped onto the modulated subcarriers. The resulting synchronization symbol consists of several repetitions in the time domain. Using the proposed sequence the resulting synchronization symbol achieves a high timing detection and frequency offset estimation accuracy. Furthermore the burst is optimized to achieve a very low envelope fluctuation (low Peak-to-Average Power Ratio) and a very low dynamic range to reduce complexity on the receiver and to save time and frequency acquisition time in the receiver. The proposed sequence is furthermore optimized with respect to all other synchronization symbols that are used to construct the synchronization and training preambles for the BCCH-DLCHs.

Abstract: An apparatus detects the addition of fuel to a fuel tank of a stopped motor vehicle under conditions of a cut off or running engine. The apparatus detects whether or not the vehicle engine is running and whether or not the tank is closed by a fuel filler cap when a tank is being filled. Vehicle speed is also measured. A first measurement of the level of fuel in the fuel tank is taken when the engine is cut off, or when the fuel filler cap is removed and the vehicle engine is running. A second measurement is taken when the vehicle engine is started up, or when the fuel filler cap is fitted onto the tank and the vehicle engine is running. The addition of fuel to the vehicle fuel tank is detected from the first and second measurements.

The second information is thus dispersed and arranged in the first information. The information may be changed in accordance with the second information and third information respectively indicating the different changing methods by each of the respective groups.  The second information (further, the third information) is extracted from the first information and is decoded.

Abstract: An artificial airway device for use in unconscious patients comprises a laryngo-pharyngeal mask including an expandable masking ring. The expandable mask sealingly surrounds the laryngeal inlet when expanded to obstruct communication between the laryngeal inlet and oesophagus. One or more airway tubes connected to the mask provide for fluid flow to a portion of the mask facing the laryngeal inlet when said mask sealingly surrounds the laryngeal inlet. A gastro-tube connected to the mask provides a fluid flow-path to the mask when the mask sealingly surrounds the laryngeal inlet. The distal end of the gastro tube passes through the masking ring at its narrower distal region where, when installed in a patient, it abuts against the oesophagus; and the distal portion of the gastro-tube flattens when the mask is deflated to facilitate smooth passage behind the larynx during insertion through the mouth and throat of the patient.

Abstract: A method and mechanism for performing branch prediction. A processor is configured with a branch prediction cache which is configured to store branch prediction information corresponding to a group of instructions. Branch marker bits are stored, each of which correspond to a different byte range of a group of instruction bytes. Each branch marker bit provides an indication as to whether or not a predicted branch instruction ends within the corresponding byte range. In response to receiving a fetch address, a corresponding branch marker bit is selected. A determination is made as to whether the selected bit indicates the presence of a predicted branch instruction. A plurality of branch prediction information entries are also maintained. If the selected branch marker bit indicates a predicted branch, the position of the selected branch marker bit relative to other branch marker bits may be used to select a corresponding entry from the branch prediction information entries.
