    • The present invention relates to reducing backflow in an electrowetting element for modifying a radiation beam characteristic. The electrowetting element comprises a first and a second fluid which are immiscible with each other and are switchable between a first configuration and a second configuration by application of a voltage across at least one of the first and second fluids. There is a tendency for backflow of the second fluid from the first configuration to the second configuration when the second fluid is switched to be provided in the first configuration. The electrowetting element comprises a backflow reducer arranged for reducing the backflow of the second fluid from the first configuration to the second configuration when the second fluid is switched to be provided in the first configuration.
    • 本发明涉及减少用于修改辐射束特性的电润湿元件中的回流。 电润湿元件包括彼此不混溶的第一和第二流体,并且可以通过在第一和第二流体中的至少一个上施加电压而在第一构型和第二构造之间切换。 当在第一配置中切换第二流体时,存在从第一配置到第二配置的第二流体的回流的趋势。 电润湿元件包括回流减流器,其设置成当第一流体被切换以在第一构造中被设置时,减少第二流体从第一构型向第二构造的回流。

    • A maskless lithography system is described having a programmable mask to allow performing several lithographic steps using the same mask. In every lithographic step, the corresponding pattern is obtained by providing a digital pattern to the programmable mask. The programmable mask includes an array of pixels which are based on the electro-wetting principle. According to this principle, every pixel has a transparent reservoir containing a first, non-polar, non-transparent fluid and a second, polar, transparent fluid which are immiscible. Applying a field to the reservoir allows to displace the fluids with respect to each other. This allows to make the pixel either transparent or non-transparent. This lithographic programmable mask allows high resolution and fast setting and refreshing. A corresponding method for performing maskless optical lithography also is described.
    • 描述了具有可编程掩模的无掩模光刻系统,以允许使用相同的掩模执行几个光刻步骤。 在每个光刻步骤中,通过向可编程掩模提供数字图案来获得相应的图案。 可编程掩模包括基于电润湿原理的像素阵列。 根据这个原理,每个像素都有一个透明的容器,它含有不混溶的第一,非极性,不透明的流体和第二个极性透明的流体。 将场施加到储存器允许流体相对于彼此移位。 这允许使像素透明或不透明。 该光刻可编程掩模允许高分辨率和快速设置和刷新。 还描述了用于执行无掩模光学光刻的相应方法。

    • The automatic candle snuffer is a mechanical timer driven device that extinguishes a candle in a jar after a user selectable time interval. A clamp mounts the candle snuffer to the mouth of the jar. The snuffing mechanism is a spring driven gear housing shaped to cover the mouth of the jar in the closed position, but which rotates around a stationary pin to uncover the jar. The gear housing contains a spring-driven timer, which drives a plurality of gears. Rotating the upper portion of the gear housing relative to the lower portion winds a timing spring, while rotating the entire housing around the pivot pin uncovers the mouth of the jar and winds a return spring. When the timer spring is unwound, a release mechanism frees the gear housing allowing the return spring to rotate the gear housing until the mouth of the jar is covered.
    • 自动蜡烛吸嘴是一种机械定时器驱动装置,可在用户可选择的时间间隔后熄灭罐中的蜡烛。 夹具将蜡烛鼻塞安装到瓶子的嘴部。 吸气机构是弹簧驱动的齿轮壳体,其被成形为在关闭位置覆盖罐的口部,但围绕固定销旋转以露出罐。 齿轮箱包含驱动多个齿轮的弹簧驱动定时器。 相对于下部旋转齿轮壳体的上部,使定时弹簧旋转,同时使整个壳体围绕枢转销旋转,从而露出罐的口并且​​卷绕复位弹簧。 当定时弹簧被释放时,释放机构释放齿轮壳体,允许复位弹簧使齿轮壳体旋转,直到盖子的口部被覆盖。
