  • Detecting and mapping of inflamed zones in a living tissue
    Patent number: 6393315
    Abstract: A method for detecting and mapping inflamed zones in living tissues and a device for implementing the method. The method includes subjecting the tissues to be analyzed to a luminous excitation with a predetermined spectral domain, acquiring at least the raw fluorescence signal of the porphyrins for a plurality of measurement points, and in determining, for each measurement point, the intensity of the fluorescence for the wavelengths characteristic of endogenous porphyrins.

  • High frequency impedance transformer
    Patent number: 5774026
    Abstract: A coupling and matching device for high frequency or microwave signal transmission includes two line sections (9, 10) with parallel, weakly coupled portions (9', 10'), where the primary section (9) forms a short circuit and is connected to a relatively low output impedance device while the secondary section (10) is connected to a relatively high input impedance device. The coupling and matching device also includes a ground plane parallel to the secondary line section (10), and a member (12) for varying the difference between the secondary line section and the ground plane.

  • Surface texture reading access checking system
    Patent number: 4677435
    Abstract: Surface texture reading access checking system. The identification information attached to each support object serving as a key is constituted by the texture of a surface portion of said object. A reader reads this information and communicates it to the processing means, which carry out a comparison between the signal read and recorded signals. Application to the production of locks or access checking means for data processing, telematic, banking and similar systems.
