  • Publication number: 20210213189
    Abstract: A blood purification apparatus capable of performing pre-substitution and post-substitution simultaneously is provided. A patient's blood flows through an arterial blood circuit and reaches a dialyzer. The blood purified by the dialyzer flows through a venous blood circuit and returns into the patient. A first substitution pump delivers substitution fluid through a substitution line to a branching point. A pre-substitution line connects the branching point and the arterial blood circuit to each other and is provided with a second substitution pump at a halfway position thereof. A post-substitution line connects the branching point and the venous blood circuit to each other and is provided with a check valve at a halfway position thereof. When the two pumps are activated simultaneously, the substitution fluid is supplied to the arterial blood circuit (pre-substitution). When only the first substitution pump is activated, the substitution fluid is supplied to the venous blood circuit (post-substitution).

  • Patent number: 10427603
    Abstract: In a display control device, a viewpoint conversion unit converts the viewpoint of images captured by cameras to obtain viewpoint converted images as viewed from above the own vehicle. A steering determination unit determines whether the steering angle of a wheel of the own vehicle is equal to or greater than a predetermined value. When the steering angle is equal to or greater than the predetermined value, an image correction unit creates a corrected image by processing a viewpoint converted image of the wheel in the viewpoint converted image so that the image of the wheel is prevented from being displayed. The image synthesis unit combines the corrected image and the other viewpoint converted images to create a synthesized image. The display control unit displays the synthesized image and an image of the own vehicle on a display device.

  • Patent number: 10160462
    Abstract: A driving support apparatus mounted to a vehicle includes: a parking space identifier that identifies a parking space by using an imaging process based on a captured image taken by an imaging device, which is mounted to the vehicle and takes an image of the surrounding of the vehicle; an overlapping degree identifier that identifies an overlapping degree of the vehicle towards the parking space based on the captured image and the parking space identified by the parking space identifier; and a speed limiter that limits a vehicle speed to be less than or equal to a maximum value, which is predetermined, when the overlapping degree identified by the overlapping degree identifier is larger to or equal to a predetermined value.

  • Patent number: 10063788
    Abstract: An image processing apparatus includes an image acquirement section, a correction section, and an image production section. The image acquirement section acquires an image signal representing an image, the image signal is generated by light receiving elements that receive lights from a specific space preliminarily defined in a vicinity of a vehicle via a near infrared passing filter mainly transmitting near infrared lights and a visible light passing filter transmitting visible lights and near infrared lights, respectively. The image includes multiple areas and indicates the specific space projected onto a plane. The correction section corrects each area of the image by amplifying intensity of near infrared lights with an increasing amplification factor when a difference between the intensity of near infrared lights and intensity of visible lights and near infrared lights becomes smaller. The image production section produces a new image based on the corrected areas of the image.

  • Patent number: 9497395
    Abstract: A night-vision device is provided with a projection unit, an image pickup unit, a luminance ratio determining unit, and a projection control unit. The luminance ratio determining unit determines whether a determination luminance ratio in a set region is within a predetermined luminance range as a luminance ratio at which a subject to be detected forms an emphasized image, said set region having been set at least in a part of an image obtained by means of the image pickup unit. In the cases where the determination luminance ratio is out of the predetermined luminance range, the projection control unit controls the intensity of near-infrared light emitted from the projection unit such that the determination luminance ratio is within the predetermined luminance range.

  • Patent number: 8926543
    Abstract: The invention provides a way of producing a natural immunologically active state in a person by subjecting him to an apheresis procedure with bioincompatible biomaterials for about one hour. To safely control the immunological shock induced by this procedure, the person is put under general anesthesia for about six hours, including the apheresis time and at least an additional five hours thereafter. This immunological activation is useful for treating malignant tumors and diseases related to immunosuppression, such as AIDS. The invention also provides for the use of an apheresis column containing a blood perfusion filter with bioincompatible materials for treating malignant tumors and infectious diseases.

  • Patent number: 8405912
    Abstract: A reflection unit reflects an image indicated on an indicator and projects the image on a combiner to indicate a virtual image of the image at a position viewable for a user. A stepping motor rotates the reflection unit to move the virtual image continuously in a predetermined section of the combiner. A control unit controls a driving power of the stepping motor such that a smoothness parameter becomes less than a predetermined value. The smoothness parameter is defined by a division of a difference between the maximum speed of the virtual image and an average speed of the virtual image, when the virtual image moves continuously in the predetermined section, by the average speed.

  • Patent number: 8368341
    Abstract: A head up display device for a vehicle includes a display; an optical system having a reflecting mirror; a stepping motor; and a control system having a determining device, a micro-step control device, and a forcible control device. The determining device determines whether an adjustment command for micro-step control is given. The micro-step control device performs the micro-step control as long as the determining device determines that the command for the micro-step control is given. The forcible control device forcibly controls a drive signal such that an electrical angle changes to a stabilizing point. When determination made by the determining device switches from determination that the command is given to determination that the command is not given, the forcible control device forcibly controls the drive signal, provided that the electrical angle as of the time of the determination that the command is not given is shifted from the stabilizing point.
