Abstract: The invention concerns the processing of audio data. The invention is characterized in that it consists in: (a) encoding signals representing a sound propagated in three-dimensional space and derived from a source located at a first distance (P) from a reference point, to obtain a representation of the sound through components expressed in a spherical harmonic base, of origin corresponding to said reference point, (b) and applying to said components compensation of a near-field effect through filtering based on a second distance (R) defining, for sound reproduction, a distance between a reproduction point (HPi), and a point (P) of auditory perception where a listener is usually located.

Abstract: A vehicle liquid dispensing system having a dispenser which may be retracted or concealed within the dashboard, a thermoelectric liquid heat exchanger for heating or cooling the liquids, an esthetically pleasing liquid reservoir and a pump: all components are disposed within the structure of the vehicle and do not take up passenger compartment space. In embodiments, an on/off switch may be provided to prevent dispensing, a switch may be provided at the dispenser to activate the pump, the pump may be electrical, and the fluid connections between the components of the system may be provided with connectors allowing easy cleaning.

Abstract: An improved process for the preparation of 4-hydroxy-3-(5-methyl-3-isoxazolylcarbamoyl)-2-methyl-2H-1,2-benzothiazine 1,1-dioxide (I), a known anti-inflammatory agent, is described. The process involves the reaction of a solution of alkyl 2,3-dihydro-3-oxo-1,2-benzisothiazole-2-acetate 1,1-dioxide (II) in dimethylformamide, with an alkali metal alkoxide using the specific portions of reactants and carefully controlled reaction conditions. Acidification of the reaction mixture precipitates out alkyl 4-hydroxy-2H-1,2-benzothiazine-3-carboxylate 1,1-dioxide (III) in substantially pure form in high yields, without recrystallization. Product III is methylated on the sulfonamide nitrogen and reacted with 3-amino-5-methylisoxazole to obtain crude I. A further improvement in the process of the invention involves a more efficient method for purifying crude product I by solubilizing in dimethylformamide with heating to 125.degree. C. to 148.degree.
