  • Patent number: 12526491
    Abstract: An acquiring system including an image-acquiring device, sensitive to visible and infrared wavelengths, including a sensor; an objective configured to focus light input into the acquiring device onto the sensor, a dual-band bandpass filter being placed in front of the sensor; a processing module configured to separate, once output by the sensor, the infrared image (IIR) and the visible image (Ivis) and to define at least one signal to be servo-controlled and an associated infrared-signal control setpoint depending on which at least one artificial light source is driven; the at least one artificial light source illuminating the scene including an artificial infrared light source.

  • Publication number: 20250154311
    Abstract: THE biobased polyurethane resin composition is obtained by mixing a volume v1 of polyisocyanate phase, and a volume v2 of polyol phase, WHERE: either the polyisocyanate phase INCLUDES at least two polyisocyanates which each INCLUDE at least 25% of biobased carbons, and the polyol phase INCLUDES at least one polyol which INCLUDES at least 80% of biobased carbons, or the polyol phase INCLUDES at least two polyols which each INCLUDES at least 80% of biobased carbons, and the polyisocyanate phase INCLUDES at least one polyisocyanate which INCLUDES at least 25% of biobased carbons. Preferentially, the number of isocyanate functions in the polyisocyanate phase is equal to the number of alcohol functions in the polyol phase. A method for manufacturing such a composition advantageously involves EVALUATING the equivalent volumes of reactive function of each compound. A printed support covered at least partly with a dome of resin produced from THE composition.

  • Patent number: 11574498
    Abstract: A biometric capture device having an optical block integrating an acquisition surface, an optical acquisition system arranged so that a first light ray propagating, outside the optical block, along an optical axis of the said optical acquisition system forms at the level of the acquisition surface, an angle with respect to a normal to the acquisition surface of a value greater than a critical angle depending on the refractive indices of the optical block and of the air, the optical system also being arranged so that the optical axis forms an angle with respect to a normal to the exit face less than said critical angle, an illumination system configured to provide illumination of the acquisition surface, the illumination system generating a light beam defined by an illumination axis, a second light ray propagating along the illumination axis out of the optical block.

  • Patent number: 11328536
    Abstract: A fingerprint detection device comprising a support having a bearing surface, a sensor arranged to capture an image of a dermatoglyph of a user's finger placed on the bearing surface, and an impedance-measuring electronic circuit connected to electrodes extending on the bearing surface, conductive tracks extending on the bearing surface between the electrodes and the impedance-measuring electronic circuit. At least two of the electrodes are connected to the impedance-measuring electronic circuit by at least two conductive tracks.

  • Patent number: 11068086
    Abstract: The present invention concerns a terminal (1) comprising a frame (10), a touchscreen (11), a glass panel (12) protecting the touchscreen (11), an outer shell (13), characterized in that successively gripped between the frame (10) and the shell (13) there are: a first seal (14a), a peripheral region (120) of the glass panel (12), and a second seal (14b); and in that the touchscreen (11) is arranged between a central portion (121) of the glass panel (12) and the frame (10), the touchscreen (11) being secured to only one from among the frame (10) and the glass panel (12). The present invention also concerns a process for manufacturing the terminal.

  • Patent number: 8469640
    Abstract: This machine includes a casing (2), a tool-holder spindle (4), a motor (6), a drive mechanism (12) having positive feed which mechanically connects the motor to the spindle and which includes a first drive member (32) for rotating the spindle, a second drive member (34) for driving the spindle in translation and which is screwed onto the spindle (4) in order to advance or return the spindle, and a clutch (36) having a return configuration which disengages the second member and the motor and an advance configuration which engages them. The clutch includes a rotary engagement member (44), a first key (48) which is movable between a position for connecting the rotary member to the motor and a position for disengaging the rotary member, and a second key (50) which is movable between a position for connecting the rotary member to the casing and a position for disengaging the rotary member.
