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 3 of the sensor 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 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.

摘要翻译：解决的问题：提供能够以高检测概率稳定地检测脉波的脉波传感器1。
解决方案：脉波传感器1包括检测部分2和传感器的主体3，它们通过专用带10和14分别固定在手腕的后侧。因此，可以使检测部分变小，并且可以使身体运动的影响较小，从而可以确保优异的S / N比。此外，与检测部2的半透明板8的人体的皮肤接触的表面侧由凸面构成。由此，能够提高透光板8与皮肤表面的密合度，能够防止来自皮肤表面的反射光或干扰光等的噪声光入侵，从而能够检测出高概率的脉波传感器可以实现。此外，将海绵或凝胶型的缓冲材料15插入在检测部2的顶部叠置的传感器的主体3和检测部2之间。由此，施加到主体3的力传感器的主体3的运动或传感器的主体3的移动不容易地传递到检测部2.版权所有（C）2005，JPO＆NCIPI

摘要： PROBLEM TO BE SOLVED: To provide a spygmographic sensor which can stably give a sphygmo gram and detect with high sensibility. SOLUTION: The pulse wave sensor 1 has a detecting section 2 and a sensor body 3 and both are respectively fixed to the back side of the wrist by means of belt 10 and 14 to be exclusively used. As a result, the mispositioning of the detecting section may be made small and the influence of the body movement may be made small and therefore a good signal-to-noise ratio may be assured. A light transmission plate 8 of the detecting section 2 is composed of a concavely curved surface on a front surface side which comes into contact with the human skin. As a result, the degree of the tight adhesion of the light transmission plate 7 to the skin surface is improved and therefore the infiltration of the reflected light quantity from the skin surface and the noise light, such as disturbance light, may be prevented. The pulse wave sensor of the high detection probability may be consequently realized. Further, sponge or buffer material 15 of a gelatinous type is inserted between a sensor body 3 arranged in superposition on the upper part of the detecting section 2 and the detecting section 2. As a result, the transfer of the force acting on the sensor body 3 and the movement of the sensor body 3 to the detecting section is made difficult.

摘要： PROBLEM TO BE SOLVED: To separate disturbance caused by the body movement included in the biological data detected by a sensor 2. SOLUTION: The biological signal detecting device 1 comprises an A/D converter 3, a separation matrix calculating means 4, a signal separation calculating means 5, and an outer output means 6. The separation matrix calculating means 4 revises the value of the separation matrix W(n) in a memory at the present time by ΔW(n) by using a digital signal at the present time sent from the A/D converter 3. The signal separation calculating means 5 calculates the product of the separation matrix sent from the separation matrix calculating means 4 and the digital signal, finds a vector y(n) consisting of a biological signal without disturbance caused by the body movement and a body movement signal indicating the disturbance caused by the body movement, and sent the vector to the outer output means 6. The outer output means 6, synchronized to a sampling frequency 100 Hz, outputs the biological signal from which the disturbance caused by the body movement is separated and the body movement signal to the outside.

摘要： PROBLEM TO BE SOLVED: To display an excellent stereoscopic video image independently of a position deviation of a viewer under a bright viewer image by photographing a viewer image not via a video display liquid crystal display panel while ensuring accurate self-tracking to the viewer. SOLUTION: A time division lighting position variable light source 10 allows both left right adjacent light source sections among a plurality of light source sections 11 to emit left and eight eye visual lights to both eyes of a viewer M through a Fresnel lens 20, a liquid crystal display panel 30, and a beam splitter 40. An image sensor 60 receives a near infrared ray of a lighting light source 70 reflected from the face of the viewer M via the beam splitter 40 and a Fresnel lens 50. Both left right adjacent light source sections 11 to be turned on in the time division lighting position variable light source 19 corresponding to the position of the viewer M are decided by using the result of light reception.

摘要： PROBLEM TO BE SOLVED: To more properly support driving according to a driver. SOLUTION: A driving environment determination part 11 selects driving environment determination cluster distribution based on distribution selection information (identification information ID, weather information W, time zone information TB), and when defining specified manipulated variables Hsb based on a vehicle speed V, steering manipulated variables S and brake manipulated variables B as a parameter for determination, estimates a driving environment by collating the parameter for determination with the selected environment determination cluster distribution. A target value setting part 15 sets target values OD and OT of an inter-vehicle distance and the time to collision suitable for the current driving environment or a driver, weather, and time zone by using an estimation model prepared for each driving environment. A driving situation estimation part 16 outputs the degree of deviation of actual detection values D and TTC corresponding to the target values OD and OT as an estimation value showing the driving situations of the driver.

摘要： PROBLEM TO BE SOLVED: To provide an image identifying device for accurately identifying an image to be extracted at high speed even when the feature of the image to be extracted varies.
SOLUTION: An identifying apparatus selection application section 22 appropriately selects an identifying apparatus from a weak identifying apparatus group, applies it to an object image, and outputs an identification result y(t). A likelihood value calculation section 23 calculates a likelihood value L(t) by multiplying the identification result y(t) by the weight w(t) of the object identifying apparatus. A likelihood value accumulation section 24 calculates accumulated likelihood value AL(t) by accumulating the likelihood values L(1) to L(t) calculated for the object image. A positive determination expected value calculation section 25 calculates positive determination expected value EP(t) by summing the weights of weak identifying devices that are not applied to the object image, of the weak identifying apparatus group for an object class. A likelihood expected value calculation section 26 calculates a likelihood expected value EL(t) by adding the positive determination expected value EP(t) to the accumulated likelihood value AL(t). Based on the likelihood expected value EL(t), a continuation control section 27 determines whether to continue the processing to the object image.

摘要： PROBLEM TO BE SOLVED: To provide a highly precise ellipse detection method and an image recognition device for executing the detection method and a controller for executing various control using an ellipse detected from an input image.
SOLUTION: A candidate graphic as the graphic(i.e., pupil) of an ellipse candidate is extracted from image data, and the intersections of a straight line(straight line C in figure) passing the central point of a candidate graphic at a set angle θ as shown by a graphic 3(b) and the outline point of the graphic of the ellipse candidate are set as a point A and a point B, and a first distance between the point A and the central point of the candidate graphic and a second distance between the point B and the central point of the candidate graphic are calculated. Then, when the first distance is equal to the second distance, the point A and the point B used in calculating the first distance and the second distance are stored as the outline formation points of the ellipse. Afterwards, the positions of the stored outline formation points are read, and the ellipse equation is solved by using a Gaussian Newton's method so that an ellipse parameter can be calculated, and that an ellipse can be restored.

摘要： PROBLEM TO BE SOLVED: To provide an ellipse detection method for detecting an ellipse in an input image with small processing quantity and an image recognition device for executing the detection method and a controller for executing various control using an ellipse detected from the input image with a small time lag from the photographing of the image.
SOLUTION: One target graphic in image data is extracted, and the center of gravity of a parallelogram inscribed in the target graphic with A point, B point, C point and D point as vertexes while a first distance and a second distance are matched is detected. Then, count at the position corresponding to the position of the center of gravity of the parallelogram of a central point candidate map preliminarily set on a memory having a coordinate system corresponding to the pixel positions of the image data is increased, and the position of the central point whose count is large on the central point candidate map is extracted as the central point of the target graphic. Furthermore, an ellipse equation is solved by using the vertex positions of a plurality of parallelograms having the center of gravity at the same position as the position of the central point of the target graphic, and the restored ellipse is compared with the candidate graphic so that the ellipse can be detected.
