  • Patent number: 11200401
    Abstract: The invention concerns a method and a biometric acquisition device for biometric vascular recognition and/or identification. The method comprising a step of capturing a plurality of veins images (116, 117, 118) of supposed subcutaneous veins (21) of a same inspecting portion (20) of a presented entity (2) from various converging orientations (113, 114, 115). The method further comprises a step of determine if said entity is a spoof based on estimated likelihood that said supposed subcutaneous veins within said plurality of veins images (116, 117, 118) are likely projections of solid veins (120).

  • Patent number: 11108309
    Abstract: A squirrel cage rotor, is made up of a shaft, a rotor laminated core with rotor bars which are arranged in the interior, and short-circuiting rings with clearances through which the bar ends of the rotor bars extend out of the rotor laminated core. The rotor bars, on their surface, at least partially have an electrical insulation layer, wherein the electrical insulation layer is cohesively connected only to the surface of the rotor bars. The squirrel cage rotor is intended, in particular, for use in an asynchronous machine.

  • Publication number: 20190264980
    Abstract: A ceramic crucible having an Al2TiO5 body with face layers of non-reactive ceramic and a method of making the crucible. The ceramic crucible is made by utilizing a plaster mold and forming a crucible body as backing material in the plaster mold with a slurry. The slurry is fired to form the crucible body of aluminum titanate. Non-reactive ceramic slurry is applied to the interior of the crucible body to a predetermined thickness, wetting the crucible body and then fired forming a non-reactive layer as the interior surface of the ceramic crucible. The non-reactive layer forming the interior surface of the ceramic crucible is more dense than non-reactive layers in prior art crucibles. The dense non-reactive layer forms a stronger bond with the crucible body, reducing the potential for delamination of the non-reactive layer when a reactive alloy is melted in the crucible by vacuum induction melting.

  • Patent number: 7372984
    Abstract: When the studied motion is periodic, such as for a beating heart, it is possible to acquire successive sets of two dimensional plus time data slice-sequences at increasing depths over at least one time period which are later rearranged to recover a three dimensional time sequence. Since gating signals are either unavailable or cumbersome to acquire in microscopic organisms, the invention is a method for reconstructing volumes based solely on the information contained in the image sequences. The central part of the algorithm is a least-squares minimization of an objective criterion that depends on the similarity between the data from neighboring depths. Owing to a wavelet-based multiresolution approach, the method is robust to common confocal microscopy artifacts. The method is validated on both simulated data and in-vivo measurements.

  • Patent number: 5472602
    Abstract: An evertable drum centrifuge has a drum with a generally cylindrical and perforate outer wall and having an axially forwardly open front end. An end wall of the drum can move axially between a closed position fitting in the front outer-wall end and an open position spaced axially forward of the outer wall and is centrally formed with a fill opening. An annular liner of a flexible foraminous filter medium has a front edge attached to the outer-wall end and a back edge attached to a rim of extension structure fixed on the end wall. When the end wall move between the closed and open positions, the liner moves from a normal position inside the drum and extending backward from the front end to the rim to an everted position substantially outside the drum and extending forward in the solids compartment from the front end to the rim. An axially displaceable fill tube carries an axially nondisplaceable fill head complementarily engageable in the fill opening and having an annular seal engageable with the fill tube.
