20150332106 | METHOD FOR EVOLUTIONARY BIOMETRIC RECOGNITION HAVING SPEED AND SECURITY FEATURES SUITABLE FOR POS/ATM APPLICATIONS - A method quickly recognizes a person by identification codes derivable from biometric data and includes registering a user, and recognizing a registered user, out of multiple registered users, through a recognition event. Each registration event includes acquiring biometric data of the user; then, encoding the biometric data into a respective registration identification code associated with the user; and registering the user and the associated registration identification code. Each recognition event includes acquiring the biometric data; then, encoding the biometric data into a respective recognition identification. Based on said registered registration identification codes, a comparison set of comparison identification codes is prepared. The recognition identification code is compared with each comparison identification code; and for each comparison, a respective matching level is estimated. The user is recognized or refused recognition based on the estimated matching levels. Each comparison includes a processing operation carried out by applying a trained algorithm. | 11-19-2015 |
20150332274 | BIOMETRIC RECOGNITION METHOD WITH SPEED AND SECURITY FEATURE SUITABLE FOR POS/ATM APPLICATIONS - A method quickly recognizes a person by identification codes derivable from biometric data includes registering and recognizing at least one user from multiple registered users by a recognition event. Each user registration event includes acquiring from biometric data correlated to a configuration of the user's blood vessels. Acquired biometric data is encoded into a respective registration identification code associated to the user. The user is registered the associated registration identification code is registered. Each recognition event includes acquiring the biometric data correlated to the user's blood vessels. The acquired biometric data is coded into a respective recognition identification user code. Based on the registered identification codes, a comparison set of comparison identification codes is prepared. Then the recognition identification code is compared with each comparison identification code. A respective matching level for each comparison is estimated. The user is recognized or refused recognition based on the estimated matching levels. | 11-19-2015 |
20150332275 | METHOD FOR BIOMETRIC RECOGNITION WITH CLUSTERING OF REGISTERED DATA FOR POS/ATM APPLICATIONS - A method quickly recognizes a person by identification codes derivable from biometric data includes registering a user, and recognizing a registered user, through a respective recognition event. Each registration event includes acquiring at least one biometric datum related to blood vessels of the user. The acquired biometric datum is encoded into a respective registration identification code and associated with the user. The user and the associated registration identification code are registered. Each recognition event includes acquiring biometric datum related to the user's blood vessels and encoding the acquired biometric datum into a respective recognition identification code. Based on the registered registration identification codes, a comparison set of comparison identification codes is prepared and compared. For each comparison, a matching level is estimated and the user is recognized or refused recognition based on the estimated matching levels. | 11-19-2015 |

20100150512 | WAVEGUIDE FOR PROPAGATING RADIATION - A low-loss waveguide that can be curved aggressively, that is, curved with a radius of curvature that is substantially zero, in the plane of propagation, without radiating, is formed by a slab of dielectric material having four metal plates, two on each opposite surface of the slab and mutually spaced to define in the dielectric slab between the four metal plates a confinement zone. In use, electromagnetic radiation injected in one end of the zone by suitable input means will propagate throughout the zone to an extraction means. Lower loss and better confinement of the radiation may be obtained by providing plugs of dielectric material adjacent the inwardly-facing edge of each of the metal plates. Embodiments of the invention can be used to implement integrated optical devices and circuits for routing or processing light signals. | 06-17-2010 |
20150162462 | METAL-INSULATOR-SEMICONDUCTOR DEVICES BASED ON SURFACE PLASMON POLARITONS - Apparatus and techniques are presented such as can be used for electro-optic modulation and detection or other applications. For example, an optical metal grating is disposed on a thin metal film to couple light from broadside to the metal film as surface plasmon-polariton waves; below the metal film is located a thin insulating layer and a doped semiconductor region forming a metal-insulator-semiconductor structure. The device can be configured to operate as a reflection or transmission modulator, or as a photodetector, for example. Modulating the voltage applied to the metal-insulator-semiconductor structure modulates the carrier concentration in the semiconductor near the insulating layer, which modulates the refractive index of the semiconductor in this region, thus modulating the coupling efficiency to the surface plasmon-polaritons, thus modulating the reflectance and transmittance of the device. Modulated incident light produces a modulated photocurrent under bias which may be detected using electronics. | 06-11-2015 |
