Abstract: The present invention discloses a contactless 3D biometric feature identification system and the method thereof. The system comprises of a fixed-viewpoint image capturing means, a lighting module capable of producing different illuminations on the object of interest and a microprocessor configured to execute a biometric identification algorithm. The algorithm starts with capturing a plurality of images with different illuminations. The captured images are then utilized to reconstruct a three dimensional surface model. Different features, for instance 2D and 3D coordinates and orientations of the biometric feature, surface curvature of the object and the local surface orientation of the object, are extracted from the captured images and the reconstructed 3D surface model. Different matching scores are also developed based on the aforesaid features to establish the identity of the biometric features.

Abstract: The present invention provides a site-specific pegylated arginase conjugate and method for producing thereof. The site-specific pegylated arginase is homogeneous in molecular weight and shows therapeutic effect for treating cancers and viral infections. The method for producing the arginase conjugate comprises genetically modifying the gene encoding an arginase so that the PEG moiety can be attached to the enzyme at a predetermined, specific intended sites. This is achieved by removing the PEG-attaching amino acid residue(s) at undesirable site(s) while keeping or adding cysteine(s) at the desirable site(s) of the enzyme. Two exemplary embodiments of the pegylated arginase conjugate are directed to human arginase I (HAI) where a polyethylene glycol (PEG) moiety is site-specific covalently bonded to Cys45 of the enzyme and Bacillus caldovelox arginase (BCA) where a polyethylene glycol (PEG) moiety is site-specific covalently bonded to Cys161 of the enzyme.

Abstract: A system using a three-coil topology for wireless power transfer is disclosed. The system comprises a primary resonator coupled to a power source, a repeater resonator and a receiver resonator. The primary resonator has a primary coil, and the repeater resonator has a repeater coil adjacent to the primary coil. The repeater coil and the primary coil are separated by a distance selected, and the repeater coil is configured, to amplify a primary-coil current by inductively generating a repeater-coil current that is substantially greater than the primary-coil current. A magnetic field contributed from both the primary-coil current and the repeater-coil current is generated while the power source needs not provide a terminal voltage across the repeater coil, thereby discouraging occurrence of voltage stress at the power source. The receiver resonator has a receiver coil, which receives the magnetic field to inductively generate a receiver-coil current for feeding to a load.
