  • Detergent tablets having an optimized shape
    Publication number: 20060258556
    Abstract: A spatially optimized form of detergent tablets, which is provided with the greatest possible volume while being useable in the largest possible number of dosing chambers of known dishwashers available on the European market. Said detergent tablets comprise a bottom surface and a top surface. The places of the two surfaces are not parallel across at least half of the size of the smaller surface.

  • Method for monitoring information density and compressing digitized signals
    Patent number: 6531971
    Abstract: The invention relates to compressing and decompressing digitized analogue signals, such as speech or music, by continuously adjusting the sampling rate to the time-varying information density of any given signal. The invention consists of three main parts: 1) a technique for measuring the time-varying information density of the signal, utilizing a line search for the optimal time-varying rate. 2) a technique for compressing and decompressing the signal by digitally resampling the signal from a constant high rate to a time-variable lower rate that follows the measured time-varying information density in the signal, and 3) a technique for decompression by resampling back to a constant high rate. The preferred embodiment utilizes a generalization of the cardinal series reconstruction kernel which is directly expressed in terms of the varying sampling rate.
