Abstract: : Methode et dispositif d'acquisition de signaux par un ensemble d'amplification, d'échantillonnage et de numérisation, adaptés à contrôler en permanence la stabilité du gain appliqué à chacun des cycles successifs d'échantillonnage effectués sur les signaux. A chaque cycle, on pratique une première numérisation d'un échantillon de signal non amplifié puis au moins une seconde numérisation d'un échantillon de signal amplifié. On mesure chaque gain réellement appliqué en faisant le rapport entre les valeurs obtenues respectivement à l'issue de chaque seconde numérisation et de la première numérisation, et l'on corrige éventuellement le gain de l'amplificateur si le (ou chaque) gain réel appliqué s'est écarté de sa valeur nominale. Application à la numérisation de signaux sismiques par exemple.

Abstract: The tank-level gauge comprises an outer tube sealed at its lower end and adapted for attachment to the top wall of a tank. The gauge also comprises two telescoping rods axially movable within the outer tube. A float encircles the outer tube. Magnets respectively attach to the float and to the lower end of the inner gauge rod, whereby a rising level causes such inner rod to rise as well. When the liquid level reaches a predetermined level, the inner gauging rod becomes disconnected and a magnet on the outer gauging rod becomes coupled to the float magnet, whereby the outer gauging rod continues to rise. Indicia on the inner gauging rod provide information on the height of the liquid in the tank from its empty condition to a partly full condition. Indicia on the outer gauging rod provide information on the quantity of liquid in the tank from its partly full condition to its full condition.

Title: In-register data manipulation in reduced instruction set processor
Inventor: SITES RICHARD L
IPC: G06F9/308
Filed: 1991-06-26
Abstract: IN-REGISTER DTA MANIPULATION          IN REDUCED INSTRUCTION SET PROCESSOR                 ABSTRACT OF THE DISCLOSURE    A high-performance CPU of the RISC (reduced instruction set) type employs a standardized, fixed instruction size, and permits only simplified memory access data width and addressing modes.  The instruction set is limited to register-to-register operations and register load/store operations.  Byte manipulation instructions, included to permit use of previously-established data structures, include the facility for doing in-register byte extract, insert and masking, along with non-aligned load and store instructions.  The provision of load/locked and store/conditional instructions permits the implementation of atomic byte writes.  By providing a conditional move instruction, many short branches can be eliminated altogether.  A conditional move instruction tests a register and moves a second register to a third if the condition is met; this function can be substituted for short branches and thus maintain the sequentiality of the instruction stream. Performance can be speeded up by predicting the target of a branch and prefetching the new instruction based upon this prediction; a branch prediction rule is followed that requires all forward branches to be predicted not-taken and all backward branches (as is common for loops) to be predicted as taken.  Another performance improvement makes use of unused bits in the standard-sized instruction to provide a hint of the expected target address for jump and jump to subroutine instructions or the like.  The target can thus be prefetched before the actual address has been calculated and placed in a register.  In addition, the unused displacement part of the jump instruction can contain a field to define the actual type of jump, i.e., jump, jump to subroutine, return from subroutine, and thus place a predicted target address in a stack to allow prefetching before the instruction has been executed.  The processor can employ a variable memory page size, so that the entries in a translation buffer for implementing virtual addressing can be optimally used.  A granularity hint is added to the page table entry to define the page size for this entry.  An additional feature is the addition of a prefetch instruction which serves to move a block of data to a faster-access cache in the memory hierarchy before the data block is to be used.

Title: Immunologically active proteins from borrelia burgdorferi, related test kits which contain these proteins and are suitable for detecting antibodies in test fluids, and the use of these proteins as vaccines against infections caused by borrelia strains
Inventor: FUCHS RENATE
IPC: A61K38/00
Filed: 1990-12-21
Abstract: Various immunologically active proteins from Borrelia burgdorferi have been prepared by genetic manipulation in microorganisms. To do this, the specific DNA sequences were selected from a B. burgdorferi gene bank using suitable screening methods, or were prepared directly by DNA amplification using selected hybridiza-tion probes, and were placed under the control of inducible promoters such as, for example, the lac promoter. It has been possible, owing to description of efficient purification methods for the expressed antigens, to provide the proteins in a suitable way.      These proteins can be used to produce specific and sensitive diagnostic assay kits. The specific combina-tion of the immunologically active proteins makes pre-cise diagnosis possible. Furthermore, monoclonal anti-bodies have been generated and are used as reagents for detecting pathogens directly in test samples or after cultivation. The Borrelia burgdorferi-specific DNA sequences can be employed for direct detection of the pathogen in patients' samples (for example by means of the PCR reaction).
