    • A toy vehicle comprises a lift mechanism which allows the toy vehicle to be lifted from a support surface in a lifting motion and roll end over end over end. The lift mechanism includes a lift arm pivotally mounted to a housing of the toy vehicle. A lift arm actuating motor is coupled to a lift arm drive screw that is in threaded engagement with a lift arm drive nut. A strut is coupled between the drive nut and the lift arm. In operation, the lift arm actuating motor drives the lift arm drive screw and causes the lift arm drive nut to drive the strut and move the lift arm into an extended position, causing the lift arm to engage a support surface to lift the toy vehicle. In the extended position, the toy vehicle is sufficiently rounded to permit the vehicle to roll end over end over end.
    • 一种玩具车包括提升机构,该提升机构允许玩具车在提升运动中从支撑表面升起并且在端部端部上方滚动端头。 提升机构包括枢转地安装到玩具车辆的壳体上的提升臂。 提升臂致动马达联接到与提升臂驱动螺母螺纹接合的提升臂驱动螺钉。 支柱联接在驱动螺母和提升臂之间。 在操作中,提升臂致动马达驱动升降臂驱动螺钉,并使提升臂驱动螺母驱动支柱并将提升臂移动到延伸位置,使提升臂接合支撑表面以提升玩具车辆。 在延伸位置,玩具车辆足够圆形,以允许车辆在端部端部上端滚动。

    • A patterned electret structure (21) on a substrate (10) comprises a dielectric structure comprising at least one non-patterned dielectric layer (22), and a charge pattern (14) in the dielectric structure and/or at a surface of a dielectric layer that is part of the dielectric structure and/or at an interface between dielectric layers that are part of the dielectric structure. By the presence of the non-patterned dielectric layer (22), the influence of the presence of a conductive substrate (10) on the charges (14) of the electret structure (21) is alleviated, hence increasing the charge stability over time. Moreover, in embodiments of the present invention, the charge stability is substantially independent of the width (W1, W2, W3) of the charge pattern. A method for manufacturing such patterned electret structure (21) is also provided.
    • 衬底(10)上的图案化驻极体结构(21)包括介电结构,其包括至少一个非图案化电介质层(22)和电介质结构中的电荷图案(14)和/或电介质的表面 层,其是电介质结构的一部分和/或作为介电结构的一部分的介电层之间的界面。 通过非图案化电介质层(22)的存在,导电基板(10)的存在对驻极体结构(21)的电荷(14)的影响被减轻,因此随时间增加电荷稳定性。 此外,在本发明的实施例中,电荷稳定性基本上与电荷图案的宽度(W1,W2,W3)无关。 还提供了制造这种图案化的驻极体结构(21)的方法。

    • A method of evaluating the condition of a laminated core of an electric machine including positioning a magnetic flux injection excitation yoke extending between a pair of teeth of the laminated core, and the excitation yoke being wound with an excitation winding defining an electrical circuit for producing a magnetic flux excitation. Power is supplied to an excitation winding wound around the yoke to produce a magnetic flux in the yoke and to form a magnetic circuit through the yoke and the laminated core. A characteristic of the electrical circuit of the excitation winding is measured to identify a fault in the magnetic circuit corresponding to an eddy current between individual laminations in the laminated core.
