Title: Extracting soft information in a block-coherent communication system
Inventor: JIN HUI
IPC: H03M13/31
Filed: 2004-04-02
Abstract: Data communication over a block-coherent channel in a communication system is described. Low-complexity demodulation techniques that allow good performance are described. A dwell syn signal (323), e.g., a set of block coherent symbols transmitted including a known symbol, e.g., a pseudo pilot symbol, are received, demodulated (204) and decoded by a joint decoder/demodulator (311 and 313) employing soft inputs, soft outputs, and interleaving of messages.  Low-complexity SISO demodulator (204) is suitable for processing pseudo-pilot modulated information corresponding to each of one or more dwells (323). The low-complexity method achieves good performance when turbo equalization is used. Some decoding and demodulation embodiments include independent phase estimates and updated independent phase estimates following the extrinsic principle to generate soft symbol values and soft bits.

Abstract: An exhaust gas recirculation control device in a diesel engine, capable of suppressing NOx and smoke discharged. A first temperature sensor (11) is provided at a portion more on the upstream side than a portion where a suction air path (3) joins an exhaust gas recirculation path (4), and a second temperature sensor (12) is provided on the downstream side.  Further, an engine load detection sensor (6) and an engine speed detection sensor (7) are arranged. The exhaust gas recirculation control device also has memory means where the temperature of suction air before it is mixed with an exhaust gas and a temperature value at a second temperature sensor installation position are previously memorized, the temperature value corresponding to an appropriate exhaust gas recirculation amount that is uniquely defined by an engine load and an engine speed. Further, judging means is provided. The judging means compares the corresponding temperature value memorized in the memory means and a value detected by the second temperature sensor. When the detected value is within a predetermined range relative to the temperature value, a circulation exhaust gas amount is determined to be appropriate, and when the detected value is not within a predetermined range relative to the temperature value, a circulation exhaust gas amount is determined to be abnormal.

Title: Clamping well casings
Inventor: VAN BILDERBEEK BERNARD HERMAN
IPC: E21B19/00
Filed: 2004-11-23
Abstract: A clamp for clamping two concentric tubes, typically two concentric tubes in an oil or gas well. The clamp has two axially movable tapered components which can be pulled over one another in an axial direction to provide a contraction of internal diameter which grips the smaller diameter tube. In one embodiment, a spacer is fitted to allow the tapered components to be held apart until the tubes have been correctly positioned. The spacer is then removed, and the tapered components are drawn together to effect the clamping. A hydraulic ram can be provided to separate the tapered components should readjustment be required. In another embodiment, the larger diameter tube is made with a relatively thin wall, so that it can be distorted inwards to grip the smaller tube.

Inventor: KONJEVIC LISAC BOZIDAR
IPC: H02M3/158
Filed: 2004-01-29
Abstract: The invention relates to a method and device for supplying a charge with electric energy recovery. According to the invention, an electric current, which circulates from the battery (UB) through the electric motor (M) and the diode (D1), charges capacitors (CA and CB) which are connected in parallel.  Once charged, said capacitors are connected in series, thereby producing a voltage difference in relation to the battery and causing half of the charge from the capacitors to be returned through the diode (D2) to the battery.  Moreover, once reconnected in parallel, the capacitors are re-charged, said charge being equal to that which was previously conveyed from the capacitors to the battery. In this way, as the capacitors are connected cyclically in parallel and in series, the energy is conveyed from the battery to the capacitors and from the capacitors to the battery, thereby considerably prolonging the autonomy of the battery and the operation of the motor.
