  • Patent number: 11302856
    Abstract: The present invention relates to an inductive dipole element for a superconducting microwave quantum circuit. The dipole element comprises a DC-SQUID formed by a pair of Josephson junctions shunted by an inductance, wherein the Josephson junctions have equal energy, and the Josephson junctions and the inductance are arranged such that each of the junctions forms a loop with the inductance. The two loops are asymmetrically threaded with external magnetic DC fluxes ?ext1 and ?ext2, respectively, such that ?ext1=? and ?ext2=0, wherein parametric pumping is enabled by modulating the total flux ??=?ext,1+?ext,2 threading the dipole element, thereby allowing even-wave mixing between modes that participate in the dipole element with no Kerr-like interactions.

  • Patent number: 11076264
    Abstract: A mobile device that is able to locate itself in a topological map using a combination of visual and radio information is provided. The mobile device captures an image of its environment, detects receivable radio transmitters and builds an observation vector that defines visual words and radio words that are present at the current location of the mobile device. It then compares this observation vector to reference vectors corresponding to reference location and identifies, based on correlations between visual words and radio words, the location of the mobile device among reference locations.

  • Patent number: 10859378
    Abstract: An iterative method for determining scattering coefficients of the cavity of a laser gyro in operation supporting two counter-propagating modes, comprises steps of: determining a set of variables dependent on characteristic physical quantities of the laser gyro, one reference variable per dependency relationship being selected from the variables; measuring values of the characteristic physical quantities of the laser gyro in operation; determining measured values of the variables; estimating, via an iterative method, estimated values of the coefficients minimising a discrepancy between the measured values of the reference variables and estimated values of the reference variables, which are estimated from the values of the coefficients and the measured values of the variables other than the reference variables; and determining estimated values of the scattering coefficients from the estimated values of the coefficients.

  • Patent number: 10301602
    Abstract: Production of virus occlusion bodies that occlude virions comprising genomes of different species of baculoviruses that can be used to combat insect pests. A method is presented for the production of occlusion derived virions (ODVs) that simultaneously comprise genomes of different baculovirus species, occluded in a viral occlusion body (OB) with the structural and morphological features characteristic of baculoviruses. Mixed genome ODVs and OBs can be produced by co-infecting insect cells or insect hosts using two or more different baculoviruses species. Co-infection may be achieved by simultaneous inoculation of the different baculoviruses or with a time interval between inoculations, which results in different proportions of each species' genomes in the ODVs and OBs that are produced. The produced OBs can be used either directly for preparing an insecticide, or to infect susceptible insects to produce larger quantities of mixed genome ODVs and OBs, also useful for combating pest insects.
