Abstract: A system and method for bad frame indication of a speech frame includes estimating a signal-to-noise ratio (SNR) and checking a cyclic redundancy code (CRC) value of the speech frame. When the speech frame fails CRC error detection or the SNR is below a pre-specified value, a bad frame indication (BFI) flag is set. When the speech frame passes CRC error detection and the SNR is above the pre-specified value, a receive signal quality metric of the speech frame is checked against a high threshold and, if need be, a low threshold. The BFI flag and the receive signal quality metric for the previous speech frame is checked when the current receive signal quality metric is between the high and low thresholds. The BFI flag is set according to the value of the SNR, the CRC value, the current and previous receive signal quality metrics, and the previous BFI flag.

Title: Low friction face sealed reaction turbine rotors
Inventor: KOLLE JACK
IPC: E21B21/14
Filed: 2004-11-17
Abstract: Rotary jetting tool including a rotor with axially-opposed pressure-balanced mechanical face seals. Vented upper mechanical face seal enables the rotor to be operated with the relativity low starting torque achievable using reaction forces from offset jets energized with a pressurized fluid. When rotor is displaced axially due to set-down conditions, a pressure chamber exerts a pressure imbalance on the rotor, forcing the rotor to return to a normal operating position. Alternate structure to achieve low starting torque includes a volume disposed adjacent to a lower mechanical face seal, the volume being coupled in fluid communication with the pressurized fluid.  Mechanical face seal surfaces are fabricated from ultra-hard materials, such as tungsten carbide, silicon carbide, and diamond. A gage ring designed to ensure the jets remove all of the material from the gage of the protective housing before the tool can advance can be incorporated.

Title: Digital television transmitter and method of coding data in digital television transmitter
Inventor: HONG YOUNG JIN
IPC: H04N19/89
Filed: 2006-09-13
Abstract: A pre-processor pre-processes enhanced data packets by coding the enhanced data packets for forward error correction (FEC) and expanding the FEC-coded data packets. A data formatter adds first null data into first place holders within each pre-processed enhanced data packet. A first multiplexer multiplexes the main data packets with the enhanced data packets having the first null data. A holder inserter inserts second null data into second place holders within an enhanced data packet outputted from the first multiplexer. A data interleaver replaces the second null data with parity data. A data generator generates at least one known data sequence. A symbol processor replaces the first null data included in an output of the data interleaver with the known data sequence(s). A non-systematic RS encoder generates the parity data by performing non-systematic RS-coding on an output of the symbol processor, and provides the parity data to the data interleaver.

Title: Refueling assemblz having a check valve receptacle and a replaceable fuel receiver for bottom-filled fuel tanks
Inventor: MACKEY DEAN E
IPC: B65B1/04
Filed: 2005-03-17
Abstract: A fuel receiver assembly, that permits replacement of a worn fuel receiver without draining the fuel tank, includes a check valve receptacle having a male-pipe-threaded nipple which engages the female-threaded pipe coupling of the fuel tank. The check valve receptacle has a spring-biased, normally closed check valve that prevents fuel from escaping from the fuel tank. Fuel pressure from the refueling pump opens the normally-closed check valve. The check valve receptacle is designed to be a relatively permanent installation in the fuel tank, having ultra-low-wear components. The check valve receptacle also has a female-threaded socket that is coaxial with the male-pipe-threaded nipple. A  specially-designed male-threaded fuel receiver engages the female-threaded socket. Sealing between the check valve receptacle and the replaceable fuel receiver is accomplished by an O-ring seal installed on the fuel receiver.

Abstract: Multiple antenna elements of a WTRU are used to form an adaptive antenna beam pattern for receiving signals in the downlink direction. The WTRU utilizes the formed antenna beam to form a transmission antenna beam for transmitting signals in the uplink direction. In an alternate embodiment, the multiple antenna elements are used to form a plurality of fixed, predetermined antenna beams. The WTRU then selects and switches to the one of the predetermined beams that yields the best downlink reception signals. The WTRU utilizes the selected beam pattern to transmit signals in the uplink direction. In an alternate embodiment, the WTRU receives spectral arrangement information and utilizing this information to avoid transmitting in the direction of spectrally adjacent WTRUs.
