A mobile terminal for use in a cellular communications network the terminal being adapted to: i) if the terminal transmits signals at a power below the maximum uplink transmission power, distributing the available uplink transmission power between different channels according to a first scheme; and ii) if the terminal transmits signals at a power exceeding or about to exceed the maximum uplink transmission power, distributing the available uplink transmission power between different channels according to a second scheme different from said first scheme.

Communication signal equalization methods and systems are disclosed. A CDMA signal having a data portion and a known portion including a known or repeated data sequence and received over a multipath communication channel represents a linear convolution between the multipath channel and a transmitted CDMA signal. A channel estimate of the communication channel is determined from the known portion, and the CDMA signal is translated into a new CDMA signal which is a cyclic convolution with the channel estimate. A frequency domain representation of the new CDMA signal is adjusted using the channel estimate to produce a frequency domain representation of an equalized signal.

Methods and apparatus are disclosed for applying successive multi-rank beamforming strategies (e.g., successive preceding strategies) for the design of precoders over a set of parallel channels. Successive beamforming is applied to a narrow band channel model and is also applied for finer quantization of a single beamforming vector (e.g., recursive beamforming). A first embodiment provides the optimal approach with high complexity. An alternative embodiment provides successive beamforming for near optimal preceding selection with medium complexity. A low complexity method for precoder selection is also provided wherein a channel representative matrix for the set of parallel channels is determined and successive beamforming on the calculated channel representative is applied.

A reduced bitline precharge level has been found to increase the SRAM Beta ratio, thus improving the stability margin. The precharge level is also supplied to Sense amplifier, write driver, and source voltages for control signals. In the sense amplifier, the lower precharge voltage compensates for performance loss in the bit-cell by operating global data-line drivers with increased overdrive. In the write driver, the reduced voltage improves the Bitline discharge rate, improves the efficiency of the negative boost write assist, and decreases the reliability exposure of transistors in the write path from negative boost circuit.

The use of turbulent contactors to simultaneously absorb selected acid gas components from a gas stream and flash off hydrocarbons entrained in a liquid stream which include a solvent or reagent for the selected gas component. In particular, the method comprises feeding the gas stream and liquid stream into a first contactor where they are contacted co-currently and subjected to turbulent mixing conditions, and passing the multi-phase flow from the first contactor to a second contactor. The multi-phase flow from the second contactor is subsequently separated into a gas phase and a liquid phase.

The present invention relates to a technique for accessing memory units in a data processing apparatus. The data processing apparatus comprises of plurality of memory units for storing data values, a processor core for issuing an access request specifying an access to be made to the memory units in relation to a data value, and a memory controller for performing the access specified by the access request. Attribute generation logic is provided for determining from the access request one or more predetermined attributes verifying which of the memory units should be used when performing the access. However, the memory controller does not wait until such determination has been performed by the attribute generation logic before beginning the access. Instead, prediction logic is arranged to predict the one or more predetermined attributes, and clock generation logic is responsive to the predictive predetermined attributes from the prediction logic to select which one of the memory units is to be clocked during performance of the access, and to issue a clock signal to that memory unit. Checking logic is then provided to determine whether the predetermined attributes generated by the attribute generation logic agree with the predicted predetermined attributes, and if not, to reinitiate the access, in which event the clock generation logic is arranged to reselect one of the memory units using the predetermined attributes as determined by the attribute generation logic. This approach enables high speed processing of access requests, whilst achieving significant power savings over prior art systems where multiple memory units are clocked speculatively in parallel.

The turbojet has a bearing which supports, in rotation and in thrust, a low-pressure compressor shaft of axis Z-Z of the engine. The bearing is lubricated with oil by means of two nozzles. A feed tube is fastened to the nose cone of the engine. This tube connects the low-pressure compressor shaft to the engine nose cone. A skin lines the wall of the engine nose cone, leaving a passage for the circulation of oil. A plurality of radial oil return tubes are placed between the most eccentric part of the skin relative to the Z-Z axis and the bearing, for returning the oil to the bearing. The return of the oil into the bearing is located at a distance R from the Z-Z axis larger than the radius r of the feed tube.
