  • Patent number: 12345583
    Abstract: A motor vehicle control case includes an outer shell with several control areas, each of the control areas assigned to a specific function of the vehicle, a printed circuit board supporting elementary sensors to generate an electrical signal in response to an action such as an approach movement, a contact or a pressure exerted by a user by having his fingers on at least one of the control areas. The elementary sensors are connected to an electronic control unit, the electrical signal generated by the elementary sensors being transmitted to the electronic control unit to be analyzed therein and converted into a control of a function of the vehicle. Each elementary sensor includes at least one insulating substrate on which are deposited conductive tracks forming a capacitive sensor and an assembly of conductive or semi-conductive nanoparticles in colloidal suspension in an electrically insulating ligand, the assembly forming a force sensor.

  • Publication number: 20230294516
    Abstract: A control device to control a motor vehicle function, includes a touch screen element having an external surface equipped with one or more control zones assigned to a specific function of the vehicle, the touch screen element supporting one or more elementary sensors positioned in line with one of the control zones. The elementary sensor(s) being capable of generating at least one signal in response to an action performed by the user on at least one of the control zones, - at least one actuator configured to provide a user with haptic feedback through a translational movement of the touch screen element, and in just-one direction of travel, - a control unit configured to receive the signal generated by the elementary sensor(s) and to control the actuator in response to the signal, wherein the control device has components to keep the touch screen element aligned in the vibration plane.

  • Patent number: 11366029
    Abstract: A compensated pressure or force sensor, especially for temperature, includes a substrate and on one side of the substrate, a first assembly of multilayer nanoparticles between the first pair of electrodes. On the same side of the substrate, near the first assembly, a second assembly of monolayer nanoparticles between the second pair of electrodes. The sensor additionally includes an electronic circuit configured to measure the variation of an electrical property of the first and second nanoparticle assemblies and to combine the measurements. A touch screen utilizing such sensor is provided.

  • Patent number: 11041147
    Abstract: The present invention relates to a bacteriophage strain capable of producing a lytic infection in the Escherichia coli ST131-025b:H4 clone. The burden of ST131-025b:H4 Escherichia coli clonal complex in human community and hospital-acquired infections is increasing worldwide, going along with a worrying and growing resistance to betalactams and fluoroquinolones. Bacteriophage LM33_P1 infects exclusively (100% specificity) 025b E. coli strains with 70% coverage on the two major antibiotic resistant pandemic clonal complexes ST131-025b:H4 and ST69-025b. The inventors evaluated the in vivo activity of bacteriophage LM33_P1 using three different extraintestinal virulence murine models and showed that it infects bacteria in several organs.

  • Publication number: 20190120838
    Abstract: The present invention relates to methods and kits for the rapid detection of the Escherichia coli O25b-ST131 clone. The inventors have isolated a podoviridae bacteriophage (LM33_P1) infecting the E. coli strain LM33 isolated from ventilator associated pneumonia and which belongs to clone STI3I-025b. By testing different strains of E coli belonging to 129 others various distinct serotypes (including twelve O25a) the inventors found that bacteriophage LM33_P1 is able to infect exclusively O25b strains (none of non-O25b strains could be infected by LM33_P1). The inventors have determined that the specificity displayed by bacteriophage LM33_P1 to infect only 025b serotype strains is based on a very specific polypeptide (Gp17) used by LM33_P1 to attach the bacterial cell via LPS molecule. In particular, the present invention relates to a polypeptide comprising an amino acid sequence having at least 80% of identity with the amino acid sequence set forth in SEQ ID NO:1.
