  • Patent number: 10551610
    Abstract: Gravitational Janus microparticle having, a center-of-mass, a center-of-volume, and a non¬uniform density, wherein: the center-of-mass and the center-of-volume are distinct. When suspended in a fluid, the microparticle substantially aligns with either: i) the gravitational field; or ii) the direction of an acceleration, such that the Janus microparticle is in substantial rotation equilibrium. After perturbation from substantial rotational equilibrium, the Janus microparticle reversibly rotates to return to substantial rotational equilibrium. The gravitational Janus microparticle may comprise at least two portions, each having distinct physical and/or chemical characteristics, wherein at least one portion provides a detectable effect following rotation and alignment of the microparticle.

  • Patent number: 10551164
    Abstract: A technique for acquiring target's coordinates for industrial dimensional metrology involves a target that serves both as a 2D contrast target and a 3D contact target, and a metrology tool. The target has proximal and distal surfaces, at least some of which being primarily flat and facing a common normal direction. At least 3 mm separate the proximal and distal surfaces in the normal direction. Reflectivity factors of the distal and proximal surfaces differ by at least 20%. Risers connecting pairs of the proximal and distal surfaces are sufficiently undercut so that none of the risers are in view at nominal viewing angles. At least two reference edges are defined where risers meet proximal surfaces. The tool has meeting features for registration with the edges and primarily flat surfaces, in at least two registered positions, to permit a retroreflector of the tool to acquire coordinates the target centre.

  • Publication number: 20200010808
    Abstract: Disclosed is a new process for the production of recombinant proteins, by transient transfection of suspension-grown human embryonic kidney cells (293 cell line and its genetic variants) with an expression vector, using polyethylenimine (PEI) as a transfection reagent. In a preferred embodiment, the process uses 293E cells expressing the Epstein-Barr virus (EBV) EBNA 1 protein, in combination with an oriP-based episomal expression vector having an improved cytomegalovirus expression cassette comprising the CMV5 promoter. The process combines in a single step the cell growth, transfection and protein expression, is carried out without changing the culture medium, and allows to achieve high expression levels in a short period of time. The process may be carried out in a serum-free, low-protein culture medium, is easily scalable, compatible with continuous production processes, and fully adapted to high-throughput production of milligram quantities of recombinant proteins.

  • Publication number: 20190359667
    Abstract: Recombinant transforming growth factor (TGF)-? monomers modified to inhibit dimerization and block TGF-? signaling are described. The recombinant TGF-? monomers lack the ability to bind and recruit TGF-? type I receptor (T?R1), but retain the capacity to bind the high affinity TGF-? type II receptor (T?RII), and in some instances, include mutations that increase their affinity for T?RII. Nucleic acid molecules and vectors encoding the recombinant TGF-? monomers are also described. Isolated cells, such as T cells, can be re-programmed with a TGF-? monomer-encoding nucleic acid or vector to secrete the monomer. Use of the recombinant TGF-? monomers and/or cells producing the recombinant TGF-? monomers, to inhibit TGF-? signaling, such as to treat disorders associated with aberrant TGF-? signaling, are also described.

  • Publication number: 20190351486
    Abstract: A substrate has a body defined at least in part by a single piece of aluminum or aluminum alloy material having a cavity and a pinch-off or other feature area and further having a metal-matrix composite (MMC) layer formed integrally in the body at the pinch-off or other feature area. A process of producing a substrate involves machining a single piece of material to provide a body having a surface and a feature area, the feature area being of smaller dimension than required for the piece, integrally forming a metal-matrix composite layer in the feature area to build up the feature area to at least a dimension required for the piece. The metal-matrix composite comprises an aluminum-nickel alloy matrix (e.g. Al-12Si alloy alloyed with Ni) having WC particles embedded therein or a aluminum matrix (e.g. Al-12Si alloy) having TiC particles embedded therein and has greater wear resistance, greater strength, greater toughness or any combination thereof than the material.

  • Publication number: 20190346370
    Abstract: A method for characterizing an aggregate sample involves using a first laser pulse to create a crater on the surface of a sample, using a second laser pulse to produce a plasma emission spectrum on the prepared crater surface, and detecting the emission spectrum to collect spectral data. Laser application, and detecting spectral emission are repeated on different points on the sample, then non-representative spectral data is discarded based on a ratio of ions to atoms in the data. Finally a calibration loading is used to determine a property characteristic of the aggregate sample. The sample may be an oil sands sample, and the properties detected may be percentages of bitumen, water, and solids. A laser-based system is provided for carrying out the characterization method.

  • Patent number: 10449676
    Abstract: Determining deviation of a multi jointed robot under load using a tribological contact between an end of the robot and any available hard constraint near the robot, involves pressing the end against the constraint, and then soliciting a movement of the end relative to the constraint in a tribologically resisted direction to apply a force that does not overbear the resistance. By measuring the force and a position encoded by the robot, a deviation of the robot under the corresponding load is determined. Correction terms may be required for deformation of the tribological surface and/or constraint. The constraint may be tooling or parts subjected to an intended process. The deviation at many measurement poses of the robot, each in multiple resisted directions, within the ordinary operating space of the robot, was used to derive compliances of the robot, and a kinetostatic model.
