[Problem] A biometric identification apparatus that can accurately and rapidly perform liveness detection with a simple structure.

[Solution] The apparatus includes a plurality of light sources 102, 103, 106, and 107, each having a wavelength different from one another, for emitting light to a finger 200 as an object to be identified, and receivers 104 and 105 for detecting the light passing through the finger. The ratio of the light emitted from the light sources to the light detected with the receivers is obtained as transmittance. Determination in liveness detection is made by comparing the transmittance with a previously-set threshold of transmittance.

An imaging apparatus consists of multiple miniaturized microscopes arranged into an array capable of simultaneously imaging respective portions of an object. A continuous linear translation approach is followed to scan the object and generate multiple image swaths of the object. In order to improve the quality of the composite image produced by concatenation of the image swaths, the performance of each microscope is normalized to the same base reference for each relevant optical-system property. Correction factors are developed through calibration to equalize the spectral response measured at each detector, to similarly balance the gains and offsets of the detector/light-source combinations associated with the various objectives, to correct for geometric misalignments between microscopes, and to correct optical and chromatic aberrations in each objective.

A method of automatic labeling using an optimum-partitioned classified neural network includes searching for neural networks having minimum errors with respect to a number of L phoneme combinations from a number of K neural network combinations generated at an initial stage or updated, updating weights during learning of the K neural networks by K phoneme combination groups searched with the same neural networks, and composing an optimum-partitioned classified neural network combination using the K neural networks of which a total error sum has converged; and tuning a phoneme boundary of a first label file by using the phoneme combination group classification result and the optimum-partitioned classified neural network combination, and generating a final label file reflecting the tuning result.

A multi-electrode mapping catheter for endocardial contact mapping of a heart chamber includes an expandable basket movable between a contracted configuration and a pre-shaped deployed configuration, the expandable basket including a plurality of flexible splines. Each spline includes a flex circuit and an electrode for mapping. A catheter shaft extending from the basket includes a lumen formed therethrough for receiving an ablation catheter for placement within the expandable basket. Each flex circuit includes a conductor that directly connects the proximal end of the catheter shaft to an electrode as a single continuous piece. In another embodiment, a shaft flex circuit extends along the length of the shaft and is electrically connected to a basket flex circuit. The expandable basket maintains the electrodes in direct contact with the wall of the heart while accommodating wall motion of the beating heart during mapping and can continually map while ablating.

Methods and systems for an engine system including an exhaust gas sensor are disclosed.

A positioning mark (20) has a shape by which a position and a direction can be identified when moved together with a separator (10) along a plane. In other words, the positioning mark (20) is formed, for example, in a cross shape so that a position on the X-axis and a position on the Y-axis and the tilt in the θ direction of the positioning mark (20) can be identified. The positioning mark (20) is optically read by, for example, a sensor, and the positions on the x-axis and the Y-axis of the positioning mark (20) are calculated by, for example, image analysis processing. Based on the calculation result, positioning of the separator (10) is performed.
