Abstract: A device for detecting defects on at least one painted surface may include: a source configured to emit electromagnetic radiation, in at least one first spectral band, in order to project a beam of the radiation onto the at least one painted surface; a video camera sensitive in at least one second spectral band and configured to obtain images of the at least one painted surface in a zone where the beam of the radiation emitted by the source is projected; and a diffuser configured to intercept at least part of the radiation emitted by the source and to make more homogeneous a spatial distribution of radiation intensity over the at least one painted surface. A spectral working band of the device is the at least one first spectral band, the at least one second spectral band, or an intersection of the at least one first and second spectral bands.

Abstract: A device for detecting defects on at least one surface may include: a source configured to emit electromagnetic radiation in at least one first spectral band; a video camera sensitive in at least one second spectral band; and a diffuser configured to intercept at least part of the electromagnetic radiation emitted by the source and to make more homogeneous a spatial distribution of intensity of the electromagnetic radiation over the at least one surface. The source may be further configured to project a beam of the electromagnetic radiation onto the at least one surface. An intersection of the at least one first spectral band and the at least one second spectral band may determine a spectral working band. A bandwidth of the spectral working band may be less than or equal to 200 nanometers (nm). The spectral working band may be between 300 nm and 1,100 nm.

Abstract: Disclosed are compositions in the form of a bioadhesive gel that adheres to the mucous membranes, in particular the vaginal mucosa, for the application of active ingredients and/or principles, comprising hydroxyethylcellulose as the only gelling agent.

Abstract: Device for frothing and heating liquids such as milk (3) and the like, comprising a substantially cylindrical intermediate body (10) which has sealingly engaged on it an upper body (20) connected to the steam supply pipe (22a) of a machine for preparing hot drinks and provided at the bottom with a nozzle (23), the nozzle (23) being arranged above an internal constriction (10b) which is followed by a coaxial cylindrical duct (12d) in which there emerge radial holes (12a) supplying air for frothing the milk (3), wherein the intermediate body (10) has fixed to it at the bottom a cylindrical body (30) onto which there is coaxially fitted a tubular element (40), wherein said cylindrical body (30) has projections (31) extending longitudinally from its external surface and designed to be engaged with corresponding seats (41) of the tubular element (40) in order to retain the latter, and wherein the tubular element (40) has recesses (51) extending longitudinally and forming longitudinal ducts supplying the frothing a
