Abstract: A computer-implemented method for generating a representation for a fingerprint includes receiving, by a computer processor, an image of a given fingerprint. The method extracts particular attributes for the given fingerprint from the image using a first neural network. The first neural network is trained to identify particular attributes in fingerprints and constructs a first feature vector from the extracted particular attributes, where the first feature vector has a first fixed length. The method includes extracting textural features of the given fingerprint from the image using a second neural network, where the second neural network is trained to identify textural features that are not limited to particular attributes and constructing a second feature vector from the extracted textural features, where the second feature vector has a second fixed length. The method includes concatenating the first feature vector with the second feature vector to form a representation for the given fingerprint.

Abstract: A system links data objects associated with a common entity and includes at least one processor. The system compares data objects within one or more source systems to identify candidate data objects associated with a corresponding common entity based on information within those data objects. The candidate data objects are analyzed based on supplemental temporal information within the one or more source systems pertaining to the candidate data objects to determine resulting data objects associated with the corresponding common entity. The resulting data objects are linked to form a set of data objects for the common entity. Embodiments of the present invention further include a method and computer program product for linking data objects associated with a common entity.

Abstract: Fingerprint recognition and matching systems and methods are described that utilize features at all three fingerprint friction ridge detail levels, i.e., Level 1, Level 2 and Level 3, extracted from 1000 ppi fingerprint scans. Level 3 features, including but not limited to pore and ridge contour characteristics, were automatically extracted using various filters (e.g., Gabor filters, edge detector filters, and/or the like) and transforms (e.g., wavelet transforms) and were locally matched using various algorithms (e.g., the iterative closest point (ICP) algorithm). Because Level 3 features carry significant discriminatory and complementary information, there was a relative reduction of 20% in the equal error rate (EER) of the matching system when Level 3 features were employed in combination with Level 1 and Level 2 features, which were also automatically extracted. This significant performance gain was consistently observed across various quality fingerprint images.

Abstract: A substantially planar fan-out circuit that receives a set of signals at one end and conducts the signals via a set of waveguides to an opposite end of the circuit. The intensity of at least one of the optical signals is detected with an optical detector integrated into the optical circuit. The detected optical signal is attenuated with a variable optical attenuator integrated into the optical circuit. The variable optical attenuator effects an attenuation level based upon an output of the optical detector. The optical signals are delivered from the second end of the optical circuit, so that the optical signals are either more or less dispersed at the second end of the optical circuit than at the first end.

Abstract: An optical multiplexer and demultiplexer for dense wavelength division multiplexed (“DWDM”) fiber optic communication systems is disclosed. As a multiplexer, the device functions to spatially combine the optical signals from several laser sources (each of which is a different wavelength) and launch the spatially combined laser beams into a single optical fiber. As a demultiplexer, the device functions to spatially separate the different wavelengths of a wavelength division multiplexed optical link and launch each of the different wavelengths into a different optical fiber. In either embodiment, the device includes both bulk optic and integrated optic components. The spatial separation or spatial combination of laser beams of different wavelength is achieved with the use of bulk diffraction gratings.

Abstract: An ultraviolet radiation monitor is disclosed. The monitor includes an aluminum gallium nitride-based detector, such as a Schottky junction fabricated with aluminum gallium nitride and a Schottky layer containing palladium, and a processor. The composition of the detector is tailored so that the detector is responsive substantially only to radiation of certain wavelengths, such as UV-B. The processor is adapted to receive user input of the user's skin type and ultraviolet-blocking power of any sunscreen the user is wearing. The processor is also adapted to read the signal generated by the detector and calculate the intensity of the ultraviolet radiation received by the detector. The processor is further adapted to calculate the maximum length ultraviolet exposure time for the user, based on the radiation intensity, skin type and sunscreen information.
