Abstract: A multi-channel echo canceller comprises a set of subtractors connected respectively in communication channels for respectively receiving a signal from a respective microphone and cancelling an echo contained in it with a cancelling signal, and a set of adaptive filters associated respectively with the subtractors. Each adaptive filter has a set of vectors of filter coefficients. A time difference between propagation delays of the received signals is estimated, and a signal having the largest content of echo components is selected and applied to the adaptive filters. One of the coefficient vectors is identified according to the estimated time difference and the selected signal. Each adaptive filter varies its filter coefficients of the identified vector with a correction term proportional to the output of the associated subtractor for filtering the selected signal using the coefficients of the identified vector to derive an echo replica, which is supplied to the associated subtractor as the cancelling signal.

Abstract: The present invention is a method for determining human expiratory flow rate, comprising a peak flow meter (36) and a zone calculator (49). The peak flow meter (36) is used to determine what the user's peak expiratory flow rate is in conjunction with medical data compiled on the zone calculator. The individual's peak expiratory flow rate and predetermined sub-optimal values ate applied to the peak flow meter as color zone settings (38, 40, 42). The peak flow meter (36) thus set is ready for the individual to use to determine whether he is functioning in the peak expiratory flow rate color zone, or one of the sub-optimal expiratory flow rate color zones. The color zones correspond to specific remedial measures to be followed by the individual in case of sub-optimal expiratory flow rate.

Abstract: A piezoelectric pressure sensor includes a generally elongate housing, a pressure receiving plate at a first end of the housing with first surface arranged to receive a pressure applied from outside the housing, a pressure transmission member in the housing with a first end in contact with a second surface of the pressure receiving plate, and a tubular piezoelectric element in the housing with a first end in contact with a second end of the pressure transmission member. A pair of electrodes are formed on the external and internal surfaces of the piezoelectric element.  An external member is in contact with the external electrode for collecting a charge on the external electrode and is encircled by a heat-shrinkable tube, while an internal member is in contact with the internal electrode for extracting a charge therefrom.  A screw is threaded into the housing for holding the piezo-electric element and the pressure transmission member against the pressure receiving plate.  During assembly of the sensor, the heat-shrinkable tube undergoes thermal shrinkage upon application of heat thereto, thereby compressing the external member radially inwardly against the external electrode.

Abstract: The invention relates to a process for the optical sorting of bulk material in a colour-sorting machine while it is conveyed over a transport belt and moves past an observation head with a light source and a product signal receiver arranged in the vicinity of the light source, whereby the reflected light of the image points of the examination material is broken down into . several spectral ranges by various colour filters of detection elements lying next to one another of a line of the receiver and the examination material is sorted on the basis of the colour values (measured value of the intensity in the colour in question). According to the invention, it is provided in order to improve the detection rate that, in the case of examination material mixed with reject parts, in each case the colour values of the product are studied in several selected sub-ranges, while, in every sub-range, a classifier ascertains connected areas of image points with colour values falling into the pertinent sub-range and carries out a classification according to preset criteria from the geometry and the size of these detection areas.

Abstract: Disclosed is a process for making soft tissue paper which includes providing a dry tissue web and then applying a sufficient amount of a chemical papermaking additive from a thin film to the dry web. The chemical papermaking additives are added to the surface of the tissue paper to enhance properties of the paper such as strength, softener, absorbency, and/or aesthetics. The chemical papermaking additive application process includes the steps of diluting the chemical papermaking additive with a suitable solvent, applying the diluted chemical solution to a heated transfer surface, evaporating the solvent from the dilute solution to form a film, and then transferring the film to the tissue by contacting the dry tissue web with the heated transfer surface. Preferably, the tissue web is dried to a moisture level below its equilibrium moisture content before application of the papermaking additive.

Abstract: In a waveguide lens (1) for primarily circularly or linearly . polarized electromagnetic radiation there is one or several rotationally symmetrical rings (5), arranged concentrically about a lens axis (3), for focusing of the incoming part of an electric magnetic wave, which has a polarization parallel to the rings (5), to a focus (11).      For a still more efficient reception one or more plates (29, 29') arranged radially are designed so that the radial component of the electromagnetic wave is focused to the same focus (11). Alternatively there is instead of rings (5) one or more spiral arms (37) extending from the lens axis (3). The lens (1) eliminates the problem of existing lens types that they only receive waves having a predetermined polarization which must be adapted to the orientation of the lens plates and the phase shifting elements. It makes for instance the reception of satellite signals more difficult, where the satellite signal is polarized in relation to the earth axis and the latitude where the satellite is located. The lens (1) focuses all polarizations equally much which is especially favourable for circularly polarized waves but is also valid for plane polarized waves.

Abstract: Sampled signals SPS of a spread-spectrum received signal are fed to matched filters 12 1 to 12 4, wherein they are despread. A spreading code of a desired signal is used as a despreading code in the matched filter 12 1, and a plurality of spreading codes which are orthogonal to the spreading code of the desired signal and orthogonal to one another are used for despreading in the matched filters 12 2 to 12 4.

A coefficient control part 37 is supplied with the signals x1 to x4 to be multiplied by the weighting coefficients w1 to w4 and the combined signal DCS and determines the weighting coefficients w1 to w4 by an algorithm that minimizes the average power of the combined signal DCS under a constraint on the weighting coefficients w1 to w4.
