Abstract: L'invention concerne un dispositif et un procédé permettant de corriger les erreurs de façon améliorée dans la mesure de la pression de traitement. Le dispositif et le procédé peuvent corriger les déformations (décalages) de diaphragme faire varier les constantes diélectriques présentes dans un environnement de champ d'exécution. Le détecteur de pression (56), rempli par du fluide diélectrique de remplissage (95), comprend au moins trois plaques de condensateur (144, 146, 148, 150), arrangées autour du diaphragme (102). Au moins deux plaques de condensateur (148, 150) sont disposées sur un côté d'un diaphragme conducteur (102), et une plaque de condensateur (148, 150) est disposée sur l'autre côté du diaphragme (102). Le procédé de la présente invention corrige les décalages et les variations du diaphragme dans la constante diélectrique du fluide de remplissage (95). La mesure de pression différentielle d'une erreur corrigée dépend du taux de déflexion du diaphragme détecté dans la région de bord (194) soustrait du taux de déflexion du diaphragme détecté dans la région centrale (140). Une façon de mesurer la déflexion du diaphragme est de mesurer les variations de capacitances de deux conducteurs de chaque côté du diaphragme (102), et de combiner les valeurs afin d'exécuter un rapport (R) d'erreur corrigée correspondant à la pression différentielle appliquée.

Abstract: The present invention relates to a cap which can form an essentially leak-proof seal with a vessel capable of receiving fluid specimens for clinical analysis and diagnosis. To minimize potentially contaminating contact between the fluid specimen and humans or the environment, the present invention features a cap which is penetrable by a plastic pipette tip or other fluid transfer device, and may include a plurality of striations which were discovered to further improve penetrability of the cap. In this way, substances can be dispensed into or withdrawn from the vessel without having to physically separate the cap from the vessel. Also featured are fluid transfer devices having rib structures which aid in improving the penetration and/or strength characteristics of standard fluid transfer devices (e.g., pipettes) and which aid in creating air gaps for venting air from the interior of a collection device to prevent or minimize the release of fluid sample in the form of an aerosol or bubbles.

Abstract: The disclosure relates to an apparatus for sterilizing a sealed enclosure (1) comprising a fan (8) for circulating a gas through a preparation circuit (11) and through the enclosure. The preparation circuit includes an evaporation chamber (10) for dispensing a decontaminant gas and water vapour mixture into the circulating gas to flow therewith through the enclosure and to reach a concentration in the enclosure above the dew point for the ambient temperature in the enclosure and thereby to condense onto surfaces in the enclosure to sterilise such surfaces. A monitor (15) measures gas temperature and dew point/condensation are monitored (17, 18) in the enclosure and the resulting signals led to a control module (19) for controlling the rate of dispensing of the decontaminant gas and water vapour into the gas in the preparation circuit in response to the levels determined by said monitoring to provide a required level of condensation of the decontaminant gas and water vapour in the enclosure.

Filed: 2000-11-01
Abstract: The present invention relates to a financial portfolio risk modeling system.  The system operates in a collaborative computing environment between the user and the portfolio development system.  The portfolio generating system models the user's personal investment parameters into a user profile in terms of the user risk tolerance level, user investment style and user bull/bear attitude. The system further calculates Value At Risk (VAR) values for the user. The system filters various securities based on their VAR and Beta values and present two lists of filtered securities, with opposing Beta values, matching the user profile. The present invention enables the user to swap securities in and out of his existing portfolio and receive an analysis of the effect of the swap on his portfolio. The model also generates an ideal portfolio based on the user profile. The present invention presents the user with an estimated value of his portfolio, based on a regression formula as well as a possible best and worst scenario based on statistical formulas.

Filed: 2001-05-02
Abstract: The present invention concerns fusion of Fc domains with biologically active peptides and a process for preparing pharmaceutical agents using biologically active peptides. In this invention, pharmacologically active compounds are prepared by a process comprising: a) selecting at least one peptide that modulates the activity of a protein of interest; and b) preparing a pharmacologic agent comprising an Fc domain covalently linked to at least one amino acid of the selected peptide. Linkage to the vehicle increases the half-life of the peptide, which otherwise would be quickly degraded in vivo. The preferred vehicle is an Fc domain. The peptide can be selected, for example, by phage display, E.coli display, ribosome display, RNA-peptide screening, yeast-based screening, chemical-peptide screening, rational design, or protein structural analysis.

Title: Algorithmic determination of connectrons
Inventor: FELDMANN RICHARD J
IPC: G16B20/30
Filed: 2001-05-31
Abstract: An algorithm has been developed to identify four DNA sequences of 20 bases or more that form a structure called a connectron. Two sequences C1 and C2 are expressed as RNA in the 3'UTR of some genes in many prokaryotic, archea and eukaryotic genomes. The other half of a connectron is two DNA sequences T1 and T2 that are 1kb to 105kb apart on the same chromosome. The C1 sequence is identical to the T1 sequence and the C2 sequence is identical to the T2 sequence. C1/C2 and T1-T2 can be on different chromosomes. The C1/C2 RNA  sequence of the gene transcript forms a triple-stranded Hoogsteen helix with the double-stranded T1 and T2 DNA sequences. The formation of connectrons blocks expression of genes between T1 and T2.
