  • Patent number: 11185337
    Abstract: The present invention relates to a tourniquet (1) comprising: • a support (2) for surrounding a first portion of a limb, • an elastic sleeve (4) to be held in a stretched position around the support (2), the support (2) preventing contraction of the elastic sleeve (4), • a grip element (8) which is movable relative to the support (2), • a drive element (6) for driving the elastic sleeve (4), when the grip element (8) is moved manually relative to the support (2), from its stretched position around the support to a blood vessel constricting position wherein the elastic sleeve (4) surrounds a second portion of the limb, adjacent to the first portion of the limb but not surrounded by the support (2), in such a way that the elastic sleeve (4) can contract by resilient return, and thus compress the second portion of the limb.

  • Patent number: 11080523
    Abstract: Disclosed is a method for pattern recognition in a plurality of received time signals of different types, the method includes: b) for each received signal, creating an asynchronous time signal including events; c) for each created asynchronous signal, creating an activity profile of the asynchronous signal which decreases as a function of the time elapsed since the last event of the asynchronous signal; d) for a given time t0: d1) determining a context defined as the set of activity profiles of the created asynchronous signals, d2) determining a standard context among predetermined standard contexts, having a minimum distance to the context determined in step d1, d3) determining the pattern as a function of the determined standard context.

  • Patent number: 10955654
    Abstract: Disclosed is an imaging device including a light source arranged so as to generate an optical signal, an optical support coupled to the light source and arranged so as to project a luminous excitation signal with a substantially constant light intensity, from the light source to a body to be observed during the use of the device, and an asynchronous camera coupled to the optical support and designed so as to generate a signal including, for each pixel of a first pixel matrix, a signal sequence representing asynchronous events corresponding to variations of the light backscattered by the body to be observed for the pixel.
