Abstract: A mixed, virtual and augmented reality headset having a front casing (2) with a housing receiving a smartphone (19) facing the holographic display (5); a curved holographic display (5) in the front portion of the headset reflecting a projected image (11) via the display of a smartphone (19) and simultaneously allowing the user to see through same; a motorised mirror (14) positioned in a withdrawn position or in an extended position in front of the holographic display (5) reflecting the projected image (11) via the smartphone (19); two motorised lenses (15) positioned in a withdrawn position or in an extended position in front of the pupils (13) of the user; a mirror system (16) reflecting a real external image (10) with respect to the headset (1) towards a camera of the smartphone (19); and a control unit (50) controlling the position of the motorised lenses (15) and mirror (14).

Abstract: A method and system for etching a hafnium containing material using a boron tri-chloride (BCl3) based process chemistry is described. A substrate having a hafnium containing layer, such as a layer of hafnium dioxide (HfO2) is subjected a dry etching process comprising BCl3 and an additive gas including: an oxygen-containing gas, such as O2; or a nitrogen-containing gas, such as N2; or a hydrocarbon gas (CxHy), such as CH4; or a combination of two or more thereof.

Abstract: Use of previously inactivated viral particles of the avian influenza virus or of previously purified antigenic components thereof, alone or in combination with carriers of biological origin in a composition administered via the respiratory system in order to prevent and to treat avian influenza, and also the composition mentioned. The product inhibits the coupling of said pathogenic virus, occupying the cell receptors for viral haemagglutinins.

Abstract: A rowing apparatus is provided for connection to a vessel and includes an oar direction-of-motion reversal assembly, fulcrum stabilizing means connected to the oar direction-of-motion reversal assembly, and vessel-to-oar-apparatus connection means connected to the fulcrum stabilizing means for connecting the apparatus to the vessel. Preferably, the oar direction-of-motion reversal assembly includes an oar handle portion, an oar blade portion, and a casement assembly for supporting the oar handle portion and the oar blade portion. A pair of oar direction-of-motion reversal assemblies are provided which provide a pair of oar handle portions and a pair of oar blade portions. The apparatus provides that a rower faces in the direction that the vessel is propelled when the rower pulls on the oar handle portions.
