    摘要: The invention relates to a method for localizing and tracking acoustic sources (101) in a multi-source environment, comprising the steps of recording audio-signals (103) of at least one acoustic source (101) with at least two recording means (104, 105), creating a two- or multi-channel recording signal, partitioning said recording signal into frames of predefined length (N), calculating for each frame a cross-correlation function as a function of discrete time-lag values (τ) for channel pairs (106, 107) of the recording signal, evaluating the cross-correlation function by calculating a sampling function depending on a pitch parameter (f0) and at least one spatial parameter (φ0), the sampling function assigning a value to every point of a multidimensional space being spanned by the pitch-parameter and the spatial parameters, and identifying peaks in said multidimensional space with respective acoustic sources in the multi-source environment.

    摘要: It is provided a method for determining whether a velocity of an object is below a predetermined threshold value, the method comprising: measuring a plurality of accelerations (337) of the object within a time interval (m*dt) from a point in time (t) to a later point in time (t + m*dt); deriving information indicative of a plurality of velocities (341) of the object within the time interval based on the measured accelerations; and determining whether the velocity is below the predetermined threshold value at the point in time by applying a criterion (C*) based on the derived information indicative of the plurality of the velocities. Also a system for carrying out the method is provided as well as a method and a system for determining a coordinate of an object.

    摘要: An apparatus for noise suppression having a linear prediction analysis circuit having an LP error filter (LFF), which takes a first, noisy voice signal y(n) = x(n) + ε(n) as a basis for producing an LP-error-filter output signal e(n), having a coefficient calculation unit (KBE), which updates the coefficients of the LP error filter on the basis of the internal signals (including the input and output signals y(n) and e(n)) in the LP error filter, and having a subtraction unit, which subtracts the LP error filter output signal e(n) from the first voice signal y(n) in a subtractor and, following the subtraction, outputs the remainder as a second voice signal x(n) = y(n) - e(n) in which the noise is suppressed, where a noise estimation unit (GSE) is provided which takes the internal signals of the LP error filter as a basis for producing a noise power signal σn2 and a voice power signal σx2, these signals are applied to the coefficient calculation unit (KBE) and said signals are used by the latter for the purpose of optimizing the noise suppression.

    摘要: The invention relates to a method which makes use of the Zeeman effect for measuring magnetic fields, by way of dark resonances. According to said method, a measuring cell (14) is exposed to the magnetic field (B) to be measured and contains the atoms of a measuring medium in a buffer gas, a radiation source (11) being provided for exciting the atoms by radiation and being connected to the modulation frequency generator and emitting electromagnetic radiation with different frequencies. A frequency detector (17) is mounted downstream of the measuring cell (14) and comprises a control loop (18) for the frequency tuning to a dark resonance frequency. The invention is characterized in that at least one modulator (22) for modulating a comparatively high first modulation frequency with a lower second modulation frequency, thereby producing a double sideband structure, is mounted downstream of the modulation frequency generator (24) to couple a plurality of dark resonances using the electromagnetic radiation (12) modulated therewith, substantially only one frequency being detected according to the magnetic field-dependent frequency shift.
