Abstract: To recognise a speech signal, it is necessary to carry out an analysis of the speech signal with the aim of extracting characteristic features. The extracted features are represented by so-called spectral feature vectors which are compared with the reference feature vectors stored for the speech signal to be recognised. The reference feature vectors are determined during a training phase in which a speech signal is recorded several times. The result of the recognition essentially depends on the quality of the spectral feature vectors or reference feature vectors. It is therefore proposed to provide recursive high-pass filtering of the spectral feature vectors. This reduces the influence of interference variables on the result of the recognition and provides for a high degree of speaker-independence of the recognition. This makes it possible to use the circuit arrangement for speech recognition even in systems which presuppose speaker-independent speech recognition.

Abstract: In the natural production of human speech, the instant of closure of the vocal cords occurs usually at well defined instants. These instants are used for speech processing, such as glottal synchronous processing or speech synthesis with observed natural vocal cord excitation signals. To detect the instants of glottal closure from an observed speech signal, the observed speech signal is high pass filtered, and a temporally localized aggregate of the number and amplitudes of peaks in the high pass filtered signal is determined for possible instants of glottal closure. The instants of glottal closure are determined as instants where the aggregate takes maximal values.

Abstract: A face classification system comprises means (3) for extracting a face from a two dimensional representation of a three dimensional scene. The input signal is applied to a homomorphic filter (2) to eliminate the effects of lighting changes in the scene. A rotation, scaling, and translation invariant representation of the face is produced (7) by means of recursive second order sub-division of moments to produce a feature vector representative of the face. The positions of the eyes and mouth are located (6) to enable two sub-divisions, one on a line joining the eyes and the other on a line perpendicular to the first line and passing through the nose. The recursive second order sub-division of moments is constrained to act first to sub-divide on these lines which reduces the effect of noise on the feature vector. The feature vector is then applied to a classifier 8, which may take the form of a multilayer perception, where it is compared with one or more previously stored faces to determine whether there is a match. 
     Such a system may be used in security systems, for example for allowing access to secure areas or for computer workstations.

Abstract: The present invention relates to a process for the production of alkali metal hydroxides, such as caustic soda, and elemental sulfur, characterized in that to an electrochemical cell an aqueous solution of an alkali metal sulfide, e.g., sodium sulfide, is fed in order to cause the following reations to take place:
     * at the anode Na₂S ---> 2Na⁺ + S + 2e⁻   * at the cathode 2H₂O + 2e⁻ ---> 2OH⁻ + H₂    with the overall reaction being thus the following: 
 
 
 
        Na₂S + 2H₂O ---> 2NaOH + S + H₂. 
 
 

     Elemental sulfur, which is insoluble, is recovered from the anodic solution by filtration. The NaOH solution is extracted from the cathodic compartment by means of the addition of water. 
     The concentration of the solution of alkali metal hydroxide obtained is a function of the characteristics of the membrane used. 
     In the disclosed process, the standard potential of the anodic reaction: 
 
 
 
        S²⁻ - 2e = S⁰ 
 
 
 
is lower than of the corresponding processes which lead to the development of gases (Cl₂, O₂), thereby an adavantageous decrease in cell voltage being made possible.

Abstract: Ink jet printhead primer apparatus includes an elongated bellows assembly (50) compressible along its length and having upper and lower end caps (101, 103). The upper cap includes an opening at which negative pressure is produced when the upper and lower end caps are relatively displaced away from each other. A capper (119) having an opening is supported by the upper end cap of the bellows assembly for selectively engagement with the nozzle array (58) of the cartridge (570)being primed to form a seal therewith so that the negative pressure produced in the opening of the upper end cap is communicated to the nozzles of the nozzle array. Displacement of the lower end cap is controlled by cam surfaces (95) formed on the inner opposing surfaces of parallel plate-like gear sectors (65) of a rotatable cam assembly(60) having gear teeth (75) that drive a flywheel (83). The gear sectors of the cam assembly further include cam edges (74a, 74b) for moving a sliding cam member (70) that moves the upper end cap between a retracted position and an extended position, wherein movement of the upper end cap from the retracted position to the extended position is away from the lower end cap. Pursuant to rotation of the cam assembly in one direction and then in the opposite direction, negative pressure is produced at the capper opening as it is engaged with the nozzle plate of the cartridge to be primed, ink suctioning negative pressure is then produced, and the capper is disengaged from the nozzle plate of the cartridge while negative pressure continues to be maintained at the opening of the capper. In this manner, negative pressure is provided at the capper opening at all times that the capper is engaged against the nozzle plate.

Abstract: Overbased sulfurized alkaline earth metal alkylphenate having excellent water tolerance properties in lubricant formulations is prepared by charging into a reactor a preheated (280-380°F) mixture of alkaline earth metal base and alkylphenol (preferably in oil), while simultaneously, but separately, charging a promoter solvent such as a glycol. Then a controlled amount of molten sulfur is charged at a rate that controls the reaction exotherm and off-gas evolution, while maintaining the 280-380°F temperature. Upon completing the sulfur charge, the reactor contents are allowed to interact at 280-380°F long enough to form the sulfurized alkylphenate. While keeping the temperature at 280-380°F, the sulfurized alkylphenate is overbased by charging the reactor simultaneously with controlled amounts of alkaline earth metal base, promoter solvent, and carbon dioxide gas, at a controlled charge rate not much greater or less than the rate at which the reactants undergo reaction to form the overbased phenate. Upon completing the charging of the alkaline earth metal base and promoter solvent, the carbon dioxide charge is continued until completion of the carbonation reaction. Unreacted alkylphenol and promoter solvent are stripped off under vacuum with inert gas purge at 400-480°F, and the resultant reaction product is filtered and the filtered product recovered. The reaction cycle time is no more than about 6 hours, and the filtered product has water tolerance properties normally associated with a batch preparation of the same product requiring a reaction cycle time of at least 8 hours.
