摘要： Local maxima values and local minima values are derived from eyelid openness time series data in a segment in which a continuous closed eye period of extracted blinks is a specific time duration (for example 1 second) or longer. When plural local minima values are present in the segment of continuous closed eye period of 1 second or longer, blinks are extracted passing over and back through each variable closed eye threshold value of a variable closed eye threshold that is slid in a direction from the derived local maxima value towards the local minima value in set steps to a low value, and a inter-blink interval derived. Determination is made that a blink burst has occurred when the derived inter-blink interval is 1 second or less, and say greater than 0.2 seconds, thereby detecting a blink burst. Blink bursts can be detected with good precision, and the state of drowsiness can be assessed with good precision.

摘要： An image is captured of a region including an eye of a driver using an image capture device 12, and the degree of eye openness is detected with a degree of eye openness detection section 24. A standard closed eye threshold value, a large value closed eye threshold value and a small closed eye threshold value stored in the threshold value storage section 28 are employed by the feature amount extraction section 30 to extract plural types of blinking feature amount from the detected degree of eye openness time series data. Threshold value determination is performed for each of the plural types of blinking feature amount by the threshold value determination section 32, and determination of the state of drowsiness of the driver is made by the drowsiness determination section 34 based on the threshold value determination results for the plural types of blinking feature amount. Accordingly, respective threshold values appropriate to the types of blinking feature amounts are employed in extracting blinking feature amounts, enabling determination of state of drowsiness to be performed with good precision.

摘要： An open-eye or closed-eye determination apparatus is provided with: an image capture section 11 for capturing an image of a region including the eye of an investigation subject; a width of eye opening measurement section 12 for detecting top and bottom eyelids of an investigation subject from the image captured by the image capture section 11 and measuring the width of eye opening between the edges of the top and bottom eyelids; a filter section 13 for subjecting the width of eye opening measured by the width of eye opening measurement section 12 to filter processing; and an open-eye or closed-eye determination section 14 for determining closed-eye when a value of the width of eye opening obtained by the filter section 13 minus the width of eye opening measured by width of eye opening measurement means is greater than a threshold value, and determining open-eye when this difference is a threshold value or less. According to this open-eye or closed-eye determination apparatus, open-eye or closed-eye determination can be made with good precision, without being influenced by image capture conditions and distance to the face.

摘要： An apparatus for easily drawing blood from arm or leg, which is provided with an inflatable air bag to be wound around the arm or leg and to intermittently squeeze a part of the arm or leg in a fixed length. Control over inflation and contraction of the air bag by means of an electronic circuit permits free and precise change of a length of time for inflating or contracting the air bag as well as pressure in the air bag. An apparatus according to this invention for drawing blood from swollen vein extending within a part between the air bag and the tip of arm of leg can increase a quantity of blood to be drawn. Therefore, this apparatus is generally used together with an extracorporporeal blood circulation and treating apparatus.

摘要： A blood collecting apparatus for collecting and reserving blood lost from the patient during or after operation, wherein thrombus contained in the collected blood is removed, and it is possible to prevent the new generation of the thrombus. The apparatus may readily be used safely. The apparatus includes a blood collecting container, a suction pipe having a branched pipe provided with a sterilizing filter, a collecting pipe provided with a port for supplying a blood anti-coagulant and a blood filter, and a discharge pipe having a blood filter. These pipes are connected to an upper part of the container. A suction unit is connected to an end portion of the suction pipe. A catheter or the like is connected to the end of the collecting pipe. The section unit is operated to suck and collect the blood from the incision during or after the operation.
