    • A bearing includes an inner race having a rotational axis and an outer race sharing the rotational axis of the inner race. Rolling bearing members are constrained between the inner race and the outer race. A retention lip is provided which is adapted to maintain a peripheral opening of a constant gauge distance between and prevent relative axial movement of the inner race and the outer race. The gauge distance of the peripheral opening is adapted to allow free passage of the rolling bearing members, upon wear on the rolling bearing members reaches a predetermined level. The bearing provides a pass or fail indication, by falling apart when the rolling bearing members have exceeded the predetermined level of wear.
    • 轴承包括具有旋转轴线的内圈和与内圈的旋转轴线共享的外圈。 滚动轴承构件被限制在内圈和外座圈之间。 提供了一种保持唇缘,其适于保持恒定的距离的周边开口,并且防止内圈和外圈的相对轴向运动。 周向开口的距离适于允许滚动轴承部件自由通过,因此滚动轴承部件上的磨损达到预定水平。 当滚动轴承部件已经超过预定的磨损水平时,轴承提供通过或失效指示。

    • A variable load circuit (2) is provided for use with a dimmer (1). A low wattage load such as a LED (3) is provided in series with the dimmer and the variable load circuit is provided in parallel with the LED. The variable load circuit has two different load characteristics: when the applied voltage from the dimmer is below a threshold, the variable load circuit presents a fixed load (24), and when the applied voltage is above a threshold the variable load circuit presents a variable load so as to act as a constant current sink. The variable load is provided by a secondary load portion (25) which may or may not act in combination with the fixed load (24), and the secondary load portion (25) is switched in or out of the variable load circuit by a trigger circuit portion (26).
