Abstract: A hearing aid includes a first microphone for providing a first audio input signal, a second microphone for providing a second audio input signal, a signal processor configured for generating a hearing loss compensated audio output signal based at least in part on the audio input signals, and a receiver for converting the audio output signal into an output sound signal, wherein the signal processor is configured to perform directional processing, based on the first and second audio input signals, in a first frequency range and substantially omni-directional processing in a second frequency range, at least a part of the first frequency range being higher than the second frequency range, and wherein a lower cutoff frequency of the first frequency range is adjustable.

Abstract: In a hearing aid with a signal processor for signal processing in accordance with selected values of a set of parameters ?, a method of automatic adjustment of a set z of the signal processing parameters ?, using a set of learning parameters ? of the signal processing parameters ? is provided, wherein the method includes extracting signal features u of a signal in the hearing aid, recording a measure r of an adjustment e made by the user of the hearing aid, modifying z by the equation z=u?+r, and absorbing the user adjustment e in ? by the equation ?N=?(u,r)+?P, wherein ?N is the new values of the learning parameter set ?, ?P is the previous values of the learning parameter set ?, and ? is a function of the signal features u and the recorded adjustment measure r.

Abstract: The present invention relates to a method for automatic adjustment of signal processing parameters in a hearing aid. It is based on an interactive estimation process that incorporates user feedback. The method is capable of incorporating user perception of sound reproduction, such as sound quality over time. The user may fine-tune the hearing aid using a volume-control wheel or a push-button on the hearing aid housing, which is linked to an adaptive parameter that is a projection of a relevant parameter space. For example, this new parameter could control simple volume, the number of active microphones, or a complex trade-off between noise reduction and signal distortion. By turning the “personalization wheel” in accordance with user preferences and absorbing these preferences in the model resident in the hearing aid, it is possible to absorb user preferences while the user wears the hearing aid device in the field.

Abstract: A television camera tube comprising an evacuated envelope enclosing an electron gun. The electron gun has, in the direction of propagation of the generated electron beam, a cathode, a grid, an anode and a cylindrical electrode. The cylindrical electrode has a diaphragm. The anode has a portion that extends substantially perpendicularly to the electron beam and includes an aperture. A first metal foil is provided on the side of the anode toward the target. The metal foil covers the aperture of the anode, but has an aperture for the electron beam. The diameter of the aperture in the foil is no more than 0.15 mm and no less than the diameter of the electron beam. A second metal foil is provided on the anode on the other side thereof. The second foil also covers the aperture of the anode. The second foil has an aperture for the electron beam. The diameter of the aperture in the second foil is smaller than the diameter of the aperture in the first metal foil, but is not less than the diameter of the electron beam.

Abstract: A method of making a colour display screen for a television display tube is disclosed. On the window portion of the tube an electron-absorbing layer is provided which is scanned by means of an electron beam via the shadow mask. The charge image on the layer is then developed xerographically. The layer is preferably photoconductive so as to be able to remove the charge remaining after the development by means of a uniform exposure.

Abstract: The invention relates to a method of determining variations in the previously adjusted nominal distance between the facing surfaces of a color selection electrode and a display window of a color television display tube in places situated near the corners of the display window. In this method the capacitance variations in that distance are determined by measuring a capacitor one electrode of which is formed by the color selection electrode and the other electrode is formed by a measuring electrode surrounded by a screening electrode, the measuring electrode being provided on the outer surface of the display window.

Abstract: A method of making a display screen for a color television display tube in which a photoconductive layer on the window portion of the tube is provided with a uniform charge which may be either positive or negative. A charge pattern is then formed on that layer by scanning it with an electron beam passing through an apertured color selection electrode. The energy of the beam is such that the average depth of penetration of the electrons is greater than the thickness of the photoconductive layer so that the charge disappears at the regions struck by the beam. The remaining charge pattern is developed with a suspension of charged phosphor particles. By repeating this process, patterns of red, green and blue luminescent phosphor particles can be successively provided to form the display screen. It is also possible to scan the layer simultaneously or successively by three electron beams and to develop the resultant charge pattern with a light-absorbing pigment.
