摘要:
The present invention relates a mechanical differential actuator for interacting with a mechanical load. The mechanical differential actuator comprises first and second semi-active sub-actuators, a velocity source and first and second mechanical differentials having three interaction ports each. The first mechanical differential includes a first interaction port coupled to the velocity source, a second interaction port and a third interaction port coupled to the first semi-active sub-actuator. The second mechanical differential includes a first interaction port coupled to the velocity source, a second interaction port and a third interaction port coupled to the second semi-active sub-actuator. Finally, the second interaction ports of the first and second mechanical differentials are coupled together to form an output which is configured so as to be coupled to the load.
摘要:
A method for producing a solid and/or porous film comprising the following steps - preparing a suspension of solid particles in a solvent and spreading (13) this suspension as a uniform layer of powder particles on a high melting point support (12), - eliminating the solvent so as to dry the uniform layer of powder particles into a dried porous uniform layer (14), - surface melting/sintering (15, 15') of the dried uniform layer by direct contact with a concentrated heat source having a controlled gas composition so as to melt/sinter this layer into a solid/porous film.

Assay supports, such as microarrays and similar devices, and methods of use and manufacture thereof, are described. The assay support is capable of assaying binding and/or activity of a bioactive entity, such as a bioactive molecule or a cell. Analytical and diagnostic uses of the supports are also described.
摘要:
A sensing device for characterizing a substance by modifying modes of resonance of surface plasmons is described. The sensing device (2) comprises: a photo-emitting substrate layer (4) for generating a luminescence signal; a dielectric adaptive layer (6) applied onto the photo-emitting substrate layer; and a sensing layer (8) applied onto the dielectric adaptive layer, the sensing layer having a sensing surface for coupling with the substance to be characterized. The luminescence signal generates surface plasmons having modes of resonance at the interface of the sensing layer and the substance to be characterized. The substance to be characterized, when coupled to the sensing layer, characteristically modifies the modes of resonance of the surface plasmons.
