  • Publication number: 20190274482
    Abstract: A machine (1) for stirring a liquid food substance has: a container (10) delimiting a cavity (11) with a bottom (12) and a peripheral wall (13) for containing said liquid food substance to be stirred, the cavity (11) extending generally along a generally upright central container axis (14) and having a mouth (15) for removing from the container (10) said liquid food substance upon stirring; and an impeller (20) comprising an impelling member (21) which is configured to be rotated in the cavity (11) against said liquid food substance about an impeller axis (22) that is generally identical or generally parallel to the container axis (14). The impelling member (21) is configured to be spaced above the cavity's bottom (12) by: a maximum stirring distance (H) when the impelling member (21) is rotated at at a maximum stirring speed about the impeller axis (22); and a resting distance (h), smaller than the maximum stirring distance (H), when the impelling member (21) stands still.

  • Patent number: 9036970
    Abstract: A coupling device for an optical fiber used in optical tomography examination of a medium includes a mass of diffusing material for a wavelength guided by the optical fiber. This mass includes a bearing surface to be applied against the surface of the medium. At least one housing is provided in the mass to receive the end of the optical fiber.

  • Patent number: 8906268
    Abstract: A phantom for medical imaging instrumentation, the phantom including a first hydrogel matrix, said matrix containing additives for simulating the optical and acoustic properties of a living organ or tissue. In the phantom, the additives include Indian ink or haemoglobin, silica powder and titanium dioxide powder. The phantom may contain a tumor simulator in solid or liquid form. It may also comprise several hydrogel matrices, each matrix including additives in different concentrations depending on the organ or tissue simulated. A method of producing the phantom includes one or more freeze-thaw cycles for optimizing the characteristics of the phantom.

  • Patent number: 8357915
    Abstract: Method and device for measuring the multi-dimensional distribution of optical characteristics of an object, by carrying out the following operations: illumination of the object by means of a pulsed light source; and acquisition of an image by modulated detection of light rays coming from the object consecutively to the illumination, the detection being modulated according to an acquisition modulation function G(t) which is continuous, non-sinusoidal and temporal, the acquisition taking place outside the phase of illumination by the light source.

  • Patent number: 8120784
    Abstract: An optical device intended for the analysis of a scattering medium, including at least one light source distant from the scattering medium and capable of providing an incident light beam intended to illuminate the scattering medium; at least one sensor capable of detecting a radiation emitted by the scattering medium; a support of the scattering medium at least partially non-absorbing for the incident light beam and the scattered radiation. All or part of the support is formed of a scattering material having a decreased scattering coefficient greater than 0.1 cm?1 and smaller than 700 cm?1.
