    • A method for controlling an injector is described, where the trigger signal for the actuator is controlled as function of the amplitude and the duration. The actuator, using an hydraulic coupler, actuates a control valve which, at a low voltage, operates in a ballistic mode and opens up an opening cross-section to an inlet channel. The opening cross-section becomes smaller with increasing trigger voltage, and the fuel quantity to one injected increases. The control valve is brought from ballistic mode to nonballistic mode via the amplitude and duration of the trigger voltage. The delivery duration and the amplitude of the trigger voltage are tuned to each other so that one or several jumps may occur, during which a switch is made from one voltage value to another voltage value, and from one delivery duration to another delivery injection. A piezoelectric element is preferably used as an actuator.
    • 描述了用于控制喷射器的方法,其中致动器的触发信号被控制为幅度和持续时间的函数。 使用液压联动器的致动器致动控制阀,该控制阀在低电压下以弹道模式操作并且向入口通道打开开口横截面。 随着触发电压的增加,开口横截面变小,一次喷射的燃料量增加。 控制阀通过触发电压的幅度和持续时间从弹道模式转为非球形模式。 触发电压的传送持续时间和振幅彼此调谐,使得可能发生一个或多个跳变,在此期间,从一个电压值到另一个电压值,以及从一个传送持续时间到另一个传送注入。 优选使用压电元件作为致动器。

    • The present invention proposes a digital camera and a corresponding method for capturing and deblurring images which remove several disadvantages of the prior art. In particular, the hardware limitation as well as the motion restriction of the known conventional MIP approach have been overcome. According to the proposed approach, image frames are electronically moved by an electronic frame shifting means. This allows a frame shifting in any type or fashion, wherein no complicated hardware arrangement is needed, as this has been required according to the known conventional MIP approach. The proposed deblurring approach is not limited to any type of frame shifting pattern, and it is furthermore not limited to a one-dimensional motion of the frames, as it also works for the case of a two-dimensional frame motion. Similar as in the conventional Motion Invariant Photography approach, the frame shifting results in a motion-invariant blurred image which can be deconvoluted by a single deconvolution.
    • 本发明提出一种用于捕获和去除图像的数字照相机和相应的方法,其消除了现有技术的若干缺点。 特别地,已经克服了已知的常规MIP方法的硬件限制以及运动限制。 根据所提出的方法,图像帧由电子帧移位装置电子地移动。 这允许以任何类型或方式移动帧,其中不需要复杂的硬件布置,因为根据已知的常规MIP方法已经需要。 所提出的去模糊方法不限于任何类型的帧移动模式,并且其不限于帧的一维运动,因为它也适用于二维帧运动的情况。 类似于常规运动不变摄影方法,帧偏移导致运动不变模糊图像,其可以通过单个去卷积去卷积。
