  • Fine particle sensor with cascaded microscales
    Patent number: 11841306
    Abstract: A sensor for the continuous in-situ analysis of an aerosol flow for measuring the mass of the micron/submicron particles suspended in the air flow, including an aeraulic sorter allowing the particles to be sorted according to their size with an impactor body with a cascade of one or more stages; at least one MEMS microbalance per stage, with an oscillating silicon membrane located on the impaction zone of the particles; processor connected to each MEMS microbalance to determine the mass of all the particles on the impaction zone; a system for cleaning the MEMS microbalances allowing the evacuation of the particles from the MEMS microbalances; means for driving the aerosol flow.

  • Motor starter device
    Patent number: 7268987
    Abstract: A motor starter device having an elongated base provided with power poles acted upon by a contactor part and a protection part. The base houses power current lines 15 and their control mechanism 20. Two movable linkages (30, 40) are associated with the mechanism, namely a first linkage 30 controlled by the electromagnet in the contactor part 16 and a second linkage 40 moved by the tripping device 18 in the protection part or by the manual control button 17. The linkages actuate signaling contacts 31, 32, 41, 42, 43 44 staggered on different levels, these contacts being housed in removable blocks A, B, added onto the housing in a fixed part C subjacent to the housing.
