    • An apparatus (100) includes a buck and boost conversion circuit (110), and a control unit (120, 200) for controlling operations of the buck and boost converter. The buck and boost converter includes a buck conversion circuit having a first set of switches (SW3, SW4), and a boost conversion circuit having a second set of switches (SW5, SW6). The buck conversion circuit and the boost conversion circuit may be controlled independently from each other. The control unit is configured to control delivery of power from the power converter to a load (20) via the buck conversion circuit in a buck conversion mode by controlling switching operations of the first set of switches, and to control the delivery of the power from the power converter to the load via the boost conversion circuit in a boost conversion mode by controlling switching operations of the second set of switches.

    • The invention relates to a position determining apparatus (6) for determining the position of an interventional instrument (1) within a subject(4). A spatial relation between positions of a second part(3) of the interventional instrument outside the subject and a first part (2) of the interventional instrument within the subject is determined based on an actual image of the interventional instrument within the subject being preferentially an x-ray image and a provided position of the second part. Once the spatial relation has been determined, the position of the interventional instrument within the subject can be determined, while the interventional instrument is moved within the subject,based on the determined spatial relation and a determined actual position of the second part outside the subject, without necessarily acquiring a further actual image. This can allow for a reduction of a radiation dose, if x-rays are used for acquiring the actual image.

    • The present invention provides a method and apparatus for tracking hand and/or wrist rotation of a user performing exercise. An aspect of the present invention proposes a method of tracking hand and/or wrist rotation of a user performing an exercise, wherein the user wears a marker on his/her hand, the method comprising the steps of: acquiring a first image and a second image of the marker by means of a camera when the hand is in a first posture and a second posture respectively; deriving the angle change of the hand and/or wrist from the change from the first posture to the second posture, based on the first image and the second image and the type of the exercise that the user is performing; and outputting the angle change of the hand and/or wrist, wherein the marker approximates a rectangular block, the marker has an opening for accommodating the palm(s) of the user and the side of the marker along the direction perpendicular to the palm is substantially shorter than two other sides. In this way, a single hand-worn marker is adequate for hand/wrist rotation tracking, so that the system implementation may be simplified and the cost for markers or other accelerometers can be saved.
    • 本发明提供一种用于跟踪执行运动的用户的手和/或腕的旋转的方法和装置。 本发明的一个方面提出了一种跟踪执行锻炼的用户的手和/或腕部旋转的方法,其中用户在他/她的手上佩戴标记,该方法包括以下步骤:获取第一图像和第二图像 当手分别处于第一姿势和第二姿势时借助于照相机的标记的图像; 基于第一图像和第二图像以及用户正在执行的运动的类型,将手和/或手腕的角度变化从第一姿势的变化导出到第二姿势; 并且输出手和/或手腕的角度变化,其中标记近似矩形块,标记具有用于容纳使用者的手掌的开口和标记沿垂直于手掌的方向的侧面是 基本短于两侧。 以这种方式,单手佩戴的标记对于手/腕旋转跟踪是足够的,从而可以简化系统实现,并且可以节省标记或其他加速度计的成本。
