Abstract: A system and method for maximizing data compression by optimizing model selection during coding of an input stream of data symbols, wherein at least two models are run and compared, and the model with the best coding performance for a given-size segment or block of compressed data is selected such that only its block is used in an output data stream. The best performance is determined by 1) respectively producing comparable-size blocks of compressed data from the input stream with the use of the two, or more, models and 2) selecting the model which compresses the most input data. In the preferred embodiment, respective strings of data are produced with each model from the symbol data and are coded with an adaptive arithmetic coder into the compressed data. Each block of compressed data is started by coding the decision to use the model currently being run and all models start with the arithmetic coder parameters established at the end of the preceding block. Only the compressed code stream of the best model is used in the output and that code stream has in it the overhead for selection of that model. Since the decision as to which model to run is made in the compressed data domain, i.e., the best model is chosen on the basis of which model coded the most input symbols for a given-size compressed block, rather than after coding a given number of input symbols, the model selection decision overhead scales with the compressed data. Successively selected compressed blocks are combined as an output code stream to produce an optimum output of compressed data, from input symbols, for storage or transmission.

Abstract: In mask-configured integrated circuits which are pin compatible substitutes for user-configured logic arrays, mask-defined routing lines having resistive/capacitive characteristics simulating those of user-configurable routing paths in the user-configurable logic array are used to replace the user-configurable routing paths. Scan testing networks are formed in the metal-configured substitutes to test the operability of logical function blocks formed on such chips. The scan testing networks comprise a plurality of test blocks each including three field effect pass transistors formed of four adjacent diffusion regions. Proper connection of the gates of these pass transistors to control lines controlling the transistors is tested by transmitting alternating high/low signals through serial conduction paths including the gate electrodes of these transistors.

Abstract: A process database includes a plurality of types of data blocks. Each block type uses categories of routines for processing data in blocks of that type, including a category of routines that are specific to the block type and a category of routines that are generic to at least two of the block types. A table contains a record of information concerning the category of routines that are specific to an individual block type. A separate table contains a record of information about the generic category of routines. This arrangement allows new types of data blocks to be added or existing block types modified (e.g., by changing routines or adding new routines) simply by creating or changing the table for that block type, without having to change the separate table for the generic routines.

Abstract: The stress wave activity produced in a surface (12) by a writing instrument (13) during the generation of a given piece of handwriting is detected by a transducer (16) and is electrically processed. The stress wave activity is compared with a stress wave activity, produced during at least one previous generation of the given piece of handwriting, held in a store (26), by a processing unit (24) in order to determine whether the detected and stored handwriting pieces have a common author. If the detected and stored handwriting pieces are determined to have a common author a weighted average of the stored stress wave activity and the detected stress wave activity is produced. The weighted average includes a weighted average of the amplitudes and a weighted average of times of events. This weighted average stress wave activity then replaces the stored stress wave activity in the store (26). This allows natural variations in the way an individual writes a given piece of handwriting to be accommodated without false indications of inauthenticity.

Abstract: A method is specified for the determination of the sand/clay component of underground layers, in which seismic data having components in at least two directions are obtained from seismic reflection measurements with the use of a source generating at least compression waves, and with partial conversion into shear waves. The invention provides that the P wave components and the shear wave components are converted into pseudo impedance/log sections, and that the data thus obtained are divided in sample fashion to determine the Vp/Vs ratio, so that it is possible from this to represent a location/depth or location/time section and interpret it as an uncalibrated pseudo gamma-ray/log section. In an improved embodiment, the ratio of Vp/Vs to prescribed values of the porosity and of the sand/clay content of the underground to be investigated is standardised, and thus represents pseudo gamma-ray/log sections which can otherwise be obtained only by borehole measurements in bore holes.

Abstract: Forms of magnesium hydroxide and/or of basic magnesium salts and also of titanium(IV) oxide which have a large surface area are mixed with potassium hydroxide solution or aqueous alkali-metal carbonate solution in a weight ratio of between approximately 1:0.5 and 1:2, or 1:1.5 and 1:4.5 to make it possible to prepare pastes of almost dry to wet consistency. Because these have a conductivity  kappa  of the order of magnitude of 10<-1> S/cm, they make it possible to manufacture alkaline primary and secondary cells having immobilised electrolytes and high power density. The specific surface area of the solids is preferably in the range 25 to 50 m<2>/g and over. The paste electrolyte can be used in the temperature range from -50 DEG C up to near the boiling point of the pure electrolyte, and its conductivity hardly differs from that of additive-free KOH electrolytes.
