Latest Patents

Jacques Attal holds a patent for a device and method designed for the determination of physical parameters for a two-phase mix by the propagation of an acoustic wave in the continuous phase of the two-phase mix. This device measures the propagation time for an acoustic wave in a continuous phase that comprises both a continuous phase and a dispersed phase forming droplets. The device includes an electro-acoustic transducer capable of emitting acoustic waves and outputting a reception signal of reflected acoustic waves. Additionally, it features a signal pulse generator that determines propagation time based on signals from the transducer, along with an acoustic lens for focusing acoustic waves. The frequency of the acoustic waves is adjusted to ensure reflection on the droplets of the dispersed phase, which are primarily located within a focusing area.
