Title: Spectrometre a deux peignes
Inventor: PARRIAUX ALEXANDRE
IPC: G01J3/433
Filed: 2021-11-16
Granted: 2024-01-12
Abstract: Un spectromètre à deux peignes (P1, P1’) comprend un guide d’onde (19) dans lequel sont propagés chacun des deux peignes, selon des modes propres distincts dudit guide d’onde. Une telle utilisation de modes propres distincts permet de réduire un mélange et des interactions entre les deux peignes. De cette façon, des signaux de détection qui sont produits par le spectromètre possèdent un rapport signal-sur-bruit qui est augmenté. Le guide d’onde peut avoir une fonction d’étalement spectral pour les deux peignes. Dans divers modes de réalisation possibles, les modes propres peuvent être différenciés par des directions de polarisation linéaire lorsque le guide d’onde est à maintien de polarisation, par des répartitions spatiales de champ à l’intérieur de sections transversales du guide d’onde lorsque ledit guide d’onde est multimode, ou par des répartitions de champ entre plusieurs cœurs du guide d’onde lorsque ledit guide d’onde est à cœurs multiples.Figure d’abrégé : Figure 1a

Abstract: A ski binding front jaw has a support member and a slide member which are independently supported for movement longitudinally of the ski. The support member has a pair of two-arm sole holder levers supported for pivotal movement about vertical axes, a first arm of each sole holder being adapted to engage a ski boot and the second arm engaging the slide member. A spring engages the support member and slide member and urges them rearwardly and forwardly, respectively, the slide member in turn urging the sole holders pivotally so that the second arms thereof are urged against the ski boot. Respective stops limit forward and rearward movement of the slide member and support member, respectively. A forward force exerted on the support member moves it forwardly relative to the slide member against the force of the spring, so that the first arms of the sole holders become spaced from the slide member and the second arms of the sole holders can pivot freely outwardly.

Abstract: The current invention presents a system for detection of bacteria combined with decontamination by means of phage administration, the so called SID (See, Identify, Destroy) system. SID is characterized by a procedure where A)Surfaces W are scanned for microbial presence, B) in case of unwanted microbial presence the micro-organism is identified up to its genome, and Cl the found contamination is eliminated with the use of bacteriophages. SID works by combining phage administration techniques with detection methods for contamination search and rapid DNA, RNA and mRNA sequencing for bacterial identification and classification. Through directed sequencing characteristic genes of the contaminating organism are identified enabling apt, immediate and automatic action by means of lytic bacteriophage decontaminants.
