摘要： In an apparatus for measuring an oxygen saturation in blood, a plurality of light emitters irradiate a living tissue with a plurality of light beams having different wavelengths. A light receiver receives the light beams reflected from or transmitted through the living tissue to generate pulse wave signals in accordance with pulsations of the blood in the living tissue. A separator separates each of the pulse wave signals into a plurality of amplitude signals each of which is associated with one frequency, thereby generating pairs of amplitude signals each of which is associated with one of a plurality of frequencies. A first processor calculates a ratio between the amplitude signals in each of the pairs of the amplitude signals. A selector selects one of the pairs of the amplitude signals. A second processor calculates the oxygen saturation from the ratio of the selected pair of the amplitude signals.

摘要： The sensor mounting time period informing apparatus is provided with the detecting part, the timer part, the discriminating part, and the informing part. The detecting part detects whether or not the sensor is mounted on the living body for measuring biological information. The timer part counts the elapsed time period during which the sensor is continuously mounted on the living body based on the detection results of the detecting part. The discriminating part discriminates whether or not the elapsed time has reached the specified standard time. The informing part issues a notification when the elapsed time has reached the standard time based on the discrimination result of the discriminating part.

摘要： According to an emergency brake device for an elevator, a brake body is capable of coming into and out of contact with an outer periphery of a sheave which is rotatable, and is capable of being displaced to a rotation direction of the sheave while maintaining a contact with the outer periphery of the sheave. Further, the brake body is arranged between the sheave and a gripper metal. The gripper metal includes an inclined portion which is caused to incline with respect to the outer periphery of the sheave. When the brake body is displaced in the rotation direction of the sheave, the brake body is meshed between the outer periphery of the sheave and the inclined portion. To the brake body, a connecting portion capable of being displaced with respect to the sheave is connected. The connecting body is displaced in a direction in which the brake body comes into and out of contact with the outer periphery of the sheave by a brake drive device.
