Abstract: In this invention, a channel estimation value of data symbols of a data channel is calculated by weighting and averaging pilot symbols in a parallel time multiplexing method. Also, a channel estimation value of data symbols during each data symbol interval is calculated by dividing data symbols in a slot into a plurality of data symbol intervals, selecting pilot symbols suitable for calculation of a channel estimation value of data symbols during each data symbol interval and weighting and averaging that pilot symbols. Also, a fading frequency is detected based on an inner product value of pilot symbols. Weighting factors are changed based on the detected fading frequency. Also, a channel estimation value is calculated by weighting and averaging pilot signals using a plurality of weighting sequences. The calculated channel estimation value is used to demodulate received data. The output data with the highest quality is selected by judging reliability of these plurality of demodulated data. It is also possible to select some weighting sequences based on the result of the reliability judgment of the demodulated data for predetermined period of time. In this case, after the selection, demodulation is performed by using these selected weighting sequences only.

Abstract: An electrostatic fluid acceleration and method of operation thereof includes at least two synchronously powered stages with final or rear-most electrodes of one stage maintained at substantially the same instantaneous voltage as the immediately adjacent initial or forward-most electrodes of a next stage in an airflow direction. A single power supply or synchronized and phase controlled power supplies provide high voltage power to each of the stages such that both the phase and amplitude of the electric power applied to the corresponding electrodes are aligned in time. The frequency and phase control allows neighboring stages to be closely spaced at a distance of from 1 to 2 times an inter-electrode distance within a stage, and, in any case, minimizing or avoiding production of a back corona current from a corona discharge electrode of one stage to an electrode of a neighboring stage. Corona discharge electrodes of neighboring stages may be horizontally aligned, complementary collector electrodes of all stages being similarly horizontally aligned between and horizontally offset from the corona discharge electrodes.

Abstract: A frequency modulated continuous wave (FMCW) radar is described that comprises a frequency sweep generator (42) for producing a swept frequency signal. A discriminator (52) receives a portion of the swept frequency signal and produces a reference difference-frequency signal. The discriminator 52 comprises an optical delay means, which may comprises a laser diode (72), an optical fibre (74) and a detector (76) for producing a time displaced frequency swept signal from which the difference-frequency signal is derived. A transceiver (50) is also described that generates the signal to be transmitted by the radar from the swept frequency signal and produces a target difference-frequency signal. An analogue-to-digital converter (80) samples the target difference-frequency signal at a rate derived from the frequency of the reference difference-frequency signal. Use of the radar in various applications, such as detecting foreign object debris on airport runways and perimeter security, are also described.

Abstract: On examine des structures et des méthodes pour empêcher la déformation de pièces moulées pendant la densification. De tels dispositifs et de telles techniques peuvent aider à atténuer les contraintes qui tendent à se traduire en partie par une déformation pendant la cuisson, le frittage ou autres procédés de densification. Elles réduisent ainsi le besoin dopérations secondaires de redressement post-densification. Dans certains cas, une structure de support est utilisée pour orienter une ébauche crue moulée dans une direction préférée pour réduire la déformation pendant la cuisson (p. ex., orienter une mince section de queue dans un plan parallèle à la direction de la gravité). La structure de support peut également faire partie, ou constituer la totalité, dune masse thermique pour aider à atténuer les contraintes qui mènent à une déformation partielle. Bien que de telles structures et méthodes puissent être utilisées pour toute pièce moulée, elles peuvent être utilisées en particulier pour créer une partie, ou la totalité, dun dispositif médical comme une mâchoire dun instrument chirurgical.
