摘要： 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.

摘要： 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.

摘要： 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.
