Abstract: L'invention concerne un approximateur non linéaire contraint utilisé dans la commande d'un processus empirique. L'approximateur contraint le comportement du dérivé d'un modèle empirique d'un sujet sans porter atteinte à la capacité du modèle de représenter des relations non linéaires génériques. Le développement de l'approximateur non linéaire contraint comprend trois étapes. La première étape consiste à spécifier la forme générale de la trajectoire de gain ou fonction non linéaire de base qui est spécifiée graphiquement, algébriquement ou génériquement et qui sert de base aux fonctions de transfert utilisées dans la seconde étape. La seconde étape consiste à interconnecter les fonctions de transfert de manière à obtenir une approximation non linéaire. L'étape finale consiste enfin à optimiser par contrainte les coefficients du modèle de façon que la forme générale des mises en correspondance d'entrée/sortie (et leurs dérivés correspondants) soit conservée.

Granted: 2013-07-02
Abstract: A method and apparatus are provided for effecting multiple mass selection or analysis steps. Fundamentally, the technique is based on moving ions in different directions through separate components of a mass spectrometer apparatus. To effect different steps, a precursor ion is selected in a first mass selector, and then passed into a collision cell, to effect fragmentation or reaction with a gas, to generate fragment or product ions. The generated product ions are then passed back into the first mass selector, and preferably back into an upstream ion trap. The product ions then pass through the first mass selector again, to select a desired product ion, for further fragmentation and analysis. These steps can be repeated a number of times. A  final mass analysis step can be effected in either a time-of-flight section or other mass analyzer. The invention enables conventional triple quadrupole mass spectrometers and QqTOF mass spectrometers to effect multiple MS steps.

Abstract: The invention relates to an anchoring rod (6) for rock anchoring (self-drilling injection bolts), comprising an outer thread (9) for connecting the anchoring rod (6) to a drilling tool (1) via a coupling sleeve (5). The end of the anchoring rod (6), which is screwed into the coupling sleeve (5), comprises a section (12) which has a reduced diameter in comparison with the outer diameter of the anchoring rod (6). The free end of the section (12) of the anchoring rod (6) with the reduced diameter comprises a bevel (11). An open space (23) is thus formed between the inner surface of the coupling sleeve (5) and the reduced diameter end of the anchoring rod (6). Said space stops the anchoring rod (6) from becoming stuck in the coupling sleeve, even when the end of the rod is plastically deformed during the drilling process, so that the anchoring rod (6) can be unscrewed from the coupling sleeve (5) without applying significant force.

Abstract: An implantable infusion apparatus has a medication reservoir for storing a medication and a carrier reservoir for storing a carrier. The entire apparatus, including both reservoirs, is typically located in a housing made of stainless steel, titanium, or any other strong corrosion resistant biocompatible material. The medication and carrier reservoirs are accessed through a medication access port and a carrier access port, respectively. The access ports are covered with a medication compound septum and a carrier compound septum, respectively.  The carrier reservoir is larger, and thus holds a larger volume, than the medication reservoir. To reduce the size of the implantable infusion apparatus, the medication is highly concentrated ,to many times the dosage required. The concentrated medication is then diluted with the carrier, to the proper dose, before it is discharged to the patient.

Abstract: A human power amplifier assist device (10) includes an end-effector (14) that is grasped by a human operator and applied to a load (25). The end-effector (14) is suspended, via a line (13), from a take-up pulley (11), winch or drum that is driven by an actuator (12) to lift or lower the load (25). The end-effector (14) includes a force sensor (31) that measures the vertical force imposed on the end-effector (14) by the operator and delivers a signal to a controller (20). The controller (20) and actuator (12) are structured in such a way that a predetermined percentage of the force necessary to lift or lower the load (25) is applied by the actuator (12), with the remaining force being supplied by the operator. The load (25) thus feels lighter to the operator, but the operator does not lose the sense of lifting against both the gravitation and inertial forces originating in the load (25).
