IPC: H04N19/65
Filed: 1987-05-29

Abstract: A high efficiency coding apparatus performs the control so that the amount of generated information does not surpass a transmission capacity of a transmission path when variable-length coding for varying a word length corresponding to a dynamic range. With respect to a still block, distribution in which a movement amount is introduced is formed taking into account that frame-dropping processing is made to obtain the number of dynamic range occurrence. Not only threshold values in the level direction for defining a word length but also movement threshold values for the frame-dropping processing are changed to control the amount of generated information. As a result, the control of the amount of generated information is performed excellently without an increase in quantization errors.

Abstract: The present invention concerns a method and a device for reducing the consumption of a stepping motor by automatically adapting the duration of each drive pulse supplied to said motor to the mechanical load that its rotor is to drive. The method comprises forming each drive pulse by a series of elementary pulses separated by interruption periods, and determining the mechanical load by measuring, during said interruption periods, a parameter which is representative of the variation in the voltage induced in the winding (11a) of the motor by the rotary movement of the rotor.

Abstract: Fabric, particularly soiled fabrics containing calcium carbonate crystal growth poisons, may be washed in hard water to which has been added a detergent active material and an alkali metal carbonate if a secondary detergency builder is added after a defined critical state of the system is reached. The secondary builder may be a precipitating, sequestering or ion exchange builder, and is added in such an amount which would be insufficient, in the absence of the carbonate, to reduce the free calcium ion concentration to less than 10-5 molar. The delayed addition can be achieved by separate dosing, coating the secondary builder, dosing the composition in the form of a two-compartment sachet or forming the secondary builder material in situ. The composition may include a material, such as calcite, to promote the occurrance of the critical state.

Abstract: A DNA sequencing system and method are described to detect the presence of radiant energy emitted from different excited reporter dye-labeled species (DNA fragments) following separation in time and/or space, and the identity of the species which emit radiant energy closely spaced in wavelength. Functions of the emitted energy are obtained which vary over the wavelengths of the closely spaced spectra in different senses and the functions ratioed, whereby the ratio is indicative of the identity of the DNA fragments. The emitting portion of the reporter-labeled DNA fragment is preferably one of a family of fluorescent dyes based on 9-carboxyethyl-6-hydroxy-3-oxo-3H-xanthene. These xanthene dyes are covalently attached to the DNA fragments through the carboxylic acid functionality, preferably via an amide linkage. The dyes may be protected by including an alkoxy group at the 9-position. A spacer may be inserted between the dye and the amine. The fluorescent dye preferably is attached to the DNA chain terminators and provides many advantages. Thus only DNA sequencing fragments resulting from bona fide termination events will carry a reporter. The DNA sequencing may also be labeled using the xanthene dyes which have general utility as fluorescent labels. Also acyclonucleoside triphosphates are described as being useful as chain terminators in DNA sequencing using a modification of the Sanger method.

Abstract: Coffee aroma gases are conveyed to a cryogenic collector in which liquid nitrogen is sprayed directly into the aroma gas stream to rapidly condense the aroma gas and form finely divided particles of coffee aroma frost suspended in a stream of nitrogen gas, while minimizing contact of the cooled gas with the walls of the collector. The suspension of aroma frost particles in gaseous nitrogen is passed through a tubular porous filter to remove the aroma frost particles which collect on the outer surface of the tubular filter, with the nitrogen gas passing through the porous filter and being exhausted from the collector. The porous filter is periodically back pulsed to dislodge aroma frost particles collected on the outer surface of the tubular filter, with the particles being recovered for incorporation in soluble coffee products. <IMAGE>

Abstract: Encoding/decoding circuitry which processes data and both corrects single errors and detects multiple errors is disclosed. The circuitry is both fail-safe and self-checking in that no internal device failure can alter data without producing improperly encoded outputs and all failures quickly reveal themselves through normal usage even if they do not actually cause any data to be modified. The circuitry can be configured in two identical halves with each half operating on one half of the data so that the circuitry can be advantageously constructed with large scale integrated circuits. Error-detecting information in the form of a syndrome produced by each circuit half is combined with similar syndrome information produced by the other circuit half. The combined syndrome information is then decoded to generate error correction information which is used to modify the data bit outputs to correct detected errors. A failure in either circuit half modifies the combined syndrome information in such a way that the modification can either be detected or else causes no erroneous data bit modification.
