Abstract: There is a need for providing a finger vein image inputting device that can miniaturize and thin a finger vein authentication apparatus and provide high authentication accuracy. The finger vein image inputting device according to the present invention includes a body, a band pass filter for transmitting only light of a specific wavelength, a light source for applying light to a finger placed over the band pass filter, and an imaging means for imaging transmitted light from the finger. A gradient index lens is provided between the band pass filter and the imaging means and causes refractive-index distribution around an optical axis. A polarizing filter is provided at least one of between the light source and the finger and between the finger and an imaging device.

Abstract: A personal authentication apparatus, being small/thin and also enabling to position a vital body with high accuracy, comprises: a first light source and a second light source, each of which is configured to irradiate infrared rays; and detector portion, which is configured to detect the infrared rays irradiated from the first and second light sources upon a vital body, whereby detecting a picture having characteristic information of the vital body from the infrared rays detected by the detector portion and executing a personal authentication, wherein irradiation is made from the first and second light sources upon the vital body, and position information of the vital body is detected from the infrared rays detected by the detector portion, thereby executing non-contacting positioning of the vital body.

Abstract: In a non-invasive glucose monitor is configured to, by using a heat conductive member having a body surface contacting part for contacting a surface of a human body at its one end, measures a first temperature adjacent to the body surface contacting part and a second temperature adjacent to the other end apart from the body surface. The computing device takes in data of the first and second temperature, environmental temperature, radiation heat from the body surface, reflection light caused by reflecting the light of the two different wavelength at the body surface contacting part. The computing device stores a relationship between parameters and blood glucose levels in advance, thereby converts the above-mentioned data to parameters, and calculates a blood glucose level by applying the parameters to the relationship.

Abstract: A biometric identification apparatus that can accurately and rapidly perform liveness detection with a simple structure. 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.

Abstract: A machine having a vertical main spindle include a bed having a bottom portion and a pair of walls arranged uprightly from both ends of the bottom portion, the sidewalls having horizontal upper mounting surfaces thereon. A first slider is slidably horizontally mounted on the upper mounting surfaces for movement along a first axis. A second slider is slidably horizontally mounted on the first slider and guided by a pair of guide rails arranged on the first slider for movement along a second axis perpendicular to the first axis. A jig apparatus is mounted on the bed for clamping a workpiece at a position lower than the first slider. A spindle head that vertically supports a main spindle is mounted on the second slider so that the main spindle is moved along the third axis perpendicular to the fist and second axes between the guide rails.

Abstract: A process time estimating apparatus is disclosed for estimating the process time for manufacturing an object such as a metal die. The apparatus includes a process time estimating section, a process occupancy time measurement section and a process program scheduling section. The process time estimating section includes a neural network device as an estimating device. An estimation input factor extracting section extracts input factors such as drawing information for an object to be manufactured. A storing section stores input factors for later neural network learning to improve the estimation capability of the system. The process occupancy time measurement section reads the process code and automatically measures the actual time involved in performing the process for a particular object being manufactured. A selecting section selects a measured process time for neural network learning.
