摘要： An attention calling apparatus operates in the following manner. That is, eyes distribution pattern is generated from the behavior of the eyes of the vehicle driver captured by a camera in a predetermined time, and driver's condition is estimated based on the distribution pattern. Further, concentration of the driver on driving is estimated based on the comparison between the distribution pattern and the stored information of distribution pattern. When the distribution pattern indicates that the degree of concentration on driving is high, the driving operation is stored in storage in association with the concentration degree. When the operation situation fulfills a notification provision condition, driver's attention is called depending on the concentration degree.

摘要： In einer Vorrichtung wendet eine Anwendungseinheit ausgewählte Klassifizierer der Reihe nach auf ein Objektbild an. Eine Punktzahlberechnungseinheit berechnet jedes Mal, wenn ein Klassifizierer auf das Objektbild angewandt wird, eine Summation eines Ausgangs von wenigstens einem Klassifizierer, der bereits auf das Objektbild angewandt wurde, um so eine Erfassungspunktzahl als die Summation zu erhalten. Der Ausgang des wenigstens einen bereits angewandten Klassifizierers wird mit einer entsprechenden Gewichtung gewichtet. Eine Verteilungsberechnungseinheit berechnet jedes Mal, wenn ein Klassifizierer auf das Objektbild angewandt wird, eine erwartete Verteilung der Erfassungspunktzahl, die erhalten werden würde, wenn wenigstens ein nicht angewandter Klassifizierer unter den Klassifizierern, der noch nicht auf das Objektbild angewandt worden ist, auf das Objektbild angewandt werden würde. Eine Beurteilungseinheit beurteilt auf der Grundlage der erwarteten Verteilung, ob ein Anwenden des wenigstens einen nicht angewandten Klassifizierers auf das Objektbild zu beenden ist.

摘要： PROBLEM TO BE SOLVED: To provide a new processing method for a polarizing optical element for forming portions in the polarizing optical element from which a polarizing characteristic as a 1/2-wavelength plate is eliminated. SOLUTION: In this processing method, a l/2-wavelength plate 30 and a carbon dioxide laser are prepared. By irradiating the 1/2-wavelength plate 30 with a laser beam from the carbon dioxide laser, portions 30A wherein the laser beam partially evaporates the 1/2-wavelength plate 30 and portions 31 from which disorder in molecular arrangement eliminates a polarizing characteristic as the 1/2-wavelength plate 30 are formed. Because the 1/2-wavelength plate 30 is processed by use of the laser beam from the carbon dioxide laser, a processing time can be reduced.

摘要： PROBLEM TO BE SOLVED: To execute factorization even if data originating from a plurality of objects exist in an observation data matrix (a feature-point position series), in a three-dimensional shape restoration device. SOLUTION: In factorizing the observation data matrix x showing the positions of the feature points originating from the plurality of objects, a shape matrix showing the shapes of the objects is assumed as z, a specifying matrix for specifying an object to which each feature point belongs is assumed as h, a motion matrix of an object u is assumed as W e¾u , measurement accuracy of the feature point originating from the object u is assumed as τ ¾u , a model parameter obtained by summarizing probability (mixing ratio) g in which the feature point belongs to each object u (u=1, 2, ..., U) is assumed as θ, and a variation Bayes estimation method is applied. A second test distribution q(z, h) is determined while a first test distribution q(θ) is fixed in an E step, and the first test distribution q(θ) is determined while the second test distribution q(z, h) is fixed in an M step, thereby probabilistically executing factorization calculation.

摘要： PROBLEM TO BE SOLVED: To provide a pulse wave sensor 1 which can detect a pulse wave stably with a high probability of detection.
SOLUTION: The pulse wave sensor 1 includes a detection section 2 and a main body of the sensor 3 which are respectively fixed to the back side of a wrist by exclusive belts 10 and 14. Thereby, a shift of the position of the detection section can be made small and an influence of a body movement can be made small so that an excellent S/N ratio can be secured. Also, a surface side to touch the skin of a human body of a translucent plate 8 of the detection section 2 is comprised of a convex surface. Thereby, a degree of adhesion of the translucent plate 8 to the skin surface is improved and reflected light from the skin surface or noise light such as disturbance light or the like can be prevented from intruding so that the pulse wave sensor with the high probability of detection can be realized. Moreover, a cushioning material 15 of a sponge or a gel type is inserted between the main body 3 of the sensor which is superposed on the top of the detection section 2 and the detection section 2. Thereby, the force applied to the main body 3 of the sensor or the movement of the main body 3 of the sensor is not easily transmitted to the detection section 2.
