    • A deep insertion vented earpiece system is described including resilient earpieces shaped to a wearer's ear canal for a conformal fit. A receptacle is provided within the outer surface of each earpiece for releasably receiving an audio plug. The audio plugs include a miniature loudspeaker and a pair of external ribs for mating with a corresponding pair of grooves formed along the periphery of the receptacle. This rib and groove feature provides for a secure retention of the audio plugs while enabling a simple removal operation. Each earpiece includes an audio passage to conduct the audio signal from the loudspeaker and a vent passage to enable continuous venting of the wearer's ear to atmosphere.
    • 描述了深插入式耳塞系统,其包括成形为佩戴者的耳道的适形配合的弹性耳机。 插座设置在每个耳机的外表面内,用于可释放地接收音频插头。 音频插头包括微型扬声器和一对外部肋条,用于与沿插座周边形成的相应的一对凹槽配合。 这种肋和凹槽功能提供了音频插头的安全保持,同时实现简单的移除操作。 每个听筒包括用于传导来自扬声器的音频信号的音频通道和一个排气通道,以使佩戴者的耳朵能连续排放到大气中。

    • An arcuate spring is coupled between a fixed vehicle member and a movable vehicle member with a pivot connection between the members interposed between the ends of the spring such that, as the movable member is moved from a first position, the axis of the pivot connection is located outside of a line intersecting the ends of the spring, thereby holding the movable member in a first position. When the movable member is moved to a second position, the pivot connection lies between the spring and a line connecting the end points of the spring to provide a bias force which holds the movable member in a second position. In one embodiment, the over-center spring is integrated with a grab handle for holding the grab handle in a deployed or retracted position. In another embodiment, the spring is associated with a vehicle panel.
    • 弧形弹簧联接在固定车辆构件和可移动车辆构件之间,其间插入在弹簧的端部之间的构件之间的枢转连接,使得当可动构件从第一位置移动时,枢转连接的轴线为 位于与弹簧的端部相交的线的外侧,从而将可动构件保持在第一位置。 当可移动部件移动到第二位置时,枢转连接位于弹簧与连接弹簧的端点的线之间,以提供将可动件保持在第二位置的偏压力。 在一个实施例中,过中心弹簧与抓握手柄集成,用于将抓握手柄保持在展开或缩回位置。 在另一个实施例中,弹簧与车辆面板相关联。
