Abstract:
Method for placing two submerged elements in a relative determined position, particularly in view of their mutual connection, comprising a first step of controlling the relative displacement of said elements on the basis of the measurement of electric values so as to ensure the alignment of a central point of one end of one element with the longitudinal axis of the other and a second step of progressively bringing the two elements in contact with each other by their relative displacement controlled on the basis of the measurement of their relative distance and mutual inclination angle, by means of acoustic emitters-receivers.
Abstract:
The invention concerns the field of microfluidics and in particular that of electrophoresis on a micro- or nanofluidic device. More particularly, the invention concerns the use of a reactive polymer coating adapted to be submitted to a phase separation under the influence of an external stimulation of chemical or physical type, to modulate the electrokinetic flows (electroosmotic or electrophoretic flows during electrophoresis for example) in a micro- or nanofluidic device. The invention also concerns a method for varying the electrokinetic flows in such a device using said coating, as well as the micro- or nanofluidic devices comprising at least one channel or one capillary tube whereof the inner surface is covered at least partly with such a coating.
Abstract:
The invention relates to an end tool for a surgical instrument, comprising a tool-holder support (1) made from a rigid material including a flat face (2) or base layer adapted to support a tool, and a surgical tool (11) formed by a stack of elementary layers adapted to be firmly joined to one another so as to form a functional tool unit that can be positioned on and firmly joined to the base layer (2) of the tool-holder support. The surgical tool includes at least one electronic layer (20) which is made using electronics and microelectronics technology and incorporates integrated connections to an electronic and/or light and/or fluid power source, and at least one electronic component (21, 22, 23) for measuring and/or actuating and/or supplying power, and an upper functional layer (33) having a form which is designed to ensure the operation of the tool.
Abstract:
A miniature valve for filling the reservoir of an apparatus for the transdermal administration of a medicine including a) a substrate, b) a fuel charge arranged on the substrate opposite the passage to be opened through it, and c) an electric resistor placed in contact with the fuel charge so that the supply of this resistor with a predetermined electric energy ensures the combustion of the charge and the opening of the passage by local rupture of the substrate under the pressure of the fuel gases of the charge. The device is useful for filling a medicine reservoir for the transdermal administration medicine aided by inophoresis.
Abstract:
A superconducting quantum-bit device based on Josephson junction has a charge as a first principal degree of freedom assigned to writing and a phase as a second principal degree of freedom assigned to reading. The device comprises a Cooper-pair box comprising first and second Josephson junctions defining a charge island of the Cooper-pair box closing up onto a superconducting loop. A read circuit comprises a read Josephson junction JL inserted into the superconducting loop and having a Josephson energy Ej at least 50 times greater than the Josephson energy of each of the first and second Josephson junctions.
Abstract:
A device for permitting the relatively precise positioning of two geometrical axes respectively of two elements at least one of the elements being associated with means capable of assuring its displacement characterized in that it comprises in combination at least two acoustic emitters-receivers disposed in a first plane substantially perpendicular to one of said geometrical axes, said axis being defined as the first axis, and capable of emitting toward said axis, said two emitter-receivers not being located on a same line passing through said first axis and in that it comprises a third emitter-receiver situated outside of said plane.
