Title: Debitmetre massique a rotor unique a effet de coriolis pourvu d'un element detecteur souple
Inventor: VAN CLEVE CRAIG BRAINERD
IPC: G01F1/82
Filed: 1996-11-12
Granted: 2002-08-06
Abstract: L'invention porte sur un débitmètre à effet de Coriolis comportant un ensemble rotor placé dans un carter et présentant un axe central de rotation. Cet ensemble rotor comporte plusieurs canaux d'écoulement, situés chacun entre son pourtour extérieur et un évidement central. Le flux de matériau traverse les canaux d'écoulement à partir d'un orifice d'admission en direction d'une sortie du débitmètre. L'ensemble rotor tourne autour de l'axe central de rotation au fur et à mesure du passage du matériau par les canaux d'écoulement. Les forces de Coriolis produites par cet écoulement et la rotation simultanée de l'ensemble rotor font qu'un élément de flexion comprenant une partie de l'ensemble rotor se décale en arc. Des jauges extensométriques ou des bobines de détection ainsi que des aimants produisent des signaux de sortie représentatifs de l'ampleur de l'inclinaison angulaire et du débit massique du matériau s'écoulant. Un moteur raccordé à l'ensemble rotor peut faire s'accélérer la vitesse de rotation de celui-ci afin de faire fonctionner le débitmètre comme une pompe produisant des signaux de sortie représentatifs du débit de la pompe.

Granted: 2002-08-27
Abstract: In order to satisfy a request for a connection path having a specified capacity between two specified terminations of a telecommunications network (91), a store (90) of routings and available capacities is searched to identify a connection path to satisfy the request; and if no connection path with adequate capacity is present in the store (90), a model (96) of the network is tested to identify suitable connection paths between the requested terminations, which are then added to the store (90), and allocated so as to satisfy the request. The search for suitable connection paths can take into account the hierarchical structure of the network (91) to identify suitable links to build up a path step by step. In a preferred arrangement the path is built up from each terminal point, at each stage using the link in the network which will bring the resulting ends of the two partial paths closest together, utilising, as a measure, a distance weighted according to the hierarchical level of the link.

Title: Microparticle enhanced light scattering agglutination assay and microparticle reagents therefor
Inventor: EDA SHINICHI
IPC: C12Q1/68
Filed: 1998-07-29
Granted: 2006-03-28
Abstract: The invention relates to a new microparticle enhanced light scattering agglutination assay for determining the amount of an analyte, and a microparticle reagent for performing that assay. The microparticle enhanced light scattering agglutination tests are quasihomogeneous and do not need a separation and washing step. They thus meet the requirements for the automation with commonly used clinical chemistry analyzers or dedicated nephelometers. Such tests provide an increased sensitivity by a factor of 2 to 3 orders of magnitude (down to 10 -11 mol/l analyte) compared to direct agglutination tests not using microparticles and, in addition, less matrix interference and higher flexibility. The specification provides a microparticle enhanced light scattering agglutination assay for determining the amount of an analyte which comprises using a mixture of particles of strong light scattering properties carrying at least one binding partner of high reactivity for the analyte and particles of weak light scattering properties carrying at least one binding partner of low reactivity for the analyte. The assay of the invention shows an unexpectedly high dynamic range (DR).

Title: Method and apparatus for compression compatible video fingerprinting
Inventor: RYAN JOHN O
IPC: H04N7/081
Filed: 1997-05-29
Granted: 2002-02-26
Abstract: Fingerprinting and fingerprint detection techniques are described which, unlike typical fingerprint systems used to conceal video signals, are compatible with all conceivable forms of signal compression systems while still allowing viewing of the video signal. The fingerprint technique is based on the principle of applying very slight local spatial distortion to the pixels in a video image, and the like, by means of selected warp patterns.  Thus the technique provides means for conveying, within the video signal, selected information in the form of the fingerprint which is detectable electronically but which is not noticeable to a critical viewer who is watching the video signal. That is, the resultant fingerprinted video signal will appear to be identical to the undistorted video signal. The fingerprint detection technique provides for the recovery of the conveyed information which may comprise an instruction to prevent the fingerprinted video image from being copied, messages which allow identifying the source and date of an unauthorized copy of the video image, etc.

Abstract: A communication system typically comprises a number of interconnected broadband-narrowband interfaces (304, 402-404) that together interact to provide a communication resource (400) that can support a call across the system. At a time when the communication resource (or a portion thereof) is apparently in place, a terminating node of a broadband- narrowband interface sends a verify-request message (452) backwards across the communication resource. A connection broker (322), coupled to both ends of the communication resource in a particular broadband- narrowband interface (404), is aware of the issuance of the verify- request message, and is therefore able to assess and report, principally, on path connectivity of the communication resource (either within the broadband-narrowband interface or between adjacent interfaces). More particularly, the connection broker expects the arrival of a path connectivity message (454, 460) issued from an end of the broadband- narrowband network responsive to the verify-request message and, as such, can provide an appropriate report (458, 470, 480) upon the timely receipt, or not, of the path connectivity message. Indeed, the verify- request message may also function to confirm path continuity.
