摘要： Operating an electrical load controller includes, in one aspect, detecting zero-crossings of an AC waveform, determining periods each corresponding to a full cycle of the AC waveform, determining a frequency of the AC waveform based on the determined periods, and controlling a supply of AC power to a load based thereon using the determined frequency to fire a switching circuit of the electrical load controller. In another aspect, a method includes maintaining a minimum on-time for which a control signal to the switching circuit is to remain in an ON state to fire the switching circuit; based on a desired load level setting of the electrical load controller, setting a corresponding control signal turn-on time to turn the control signal to the ON state to conduct the supply of AC power to the load.

摘要： An illuminated electrical load control is provided for controlling electrical power to a light-emitting diode (LED) lighting load. The load control includes a wall-box mounted housing, and an electrical switch assembly disposed at least partially within the housing. The switch assembly includes an actuator coupled to transition the switch assembly between an ON state, where AC current flows to the LED lighting load, and an OFF state, where current is interrupted from flowing to the LED lighting load. Further, the load control includes an illumination assembly with an indicator light to illuminate, at least in part, the load control when the switch assembly is in OFF state, and a current-limiting circuit connected across terminals of the switch assembly, and configured to limit leakage current through to the LED lighting load to below an activation current of the LED lighting load when the switch assembly is in the OFF state.

摘要： A fiber optic connector assembly incorporates features that improve structural rigidity and the integrity of transmitted signals. These features also allow the connector assembly to be accessed easily in high density connectivity environments. These features also facilitate a technique for reversing polarity of the connector assembly with little or no risk of twisting the optical fibers and without requiring the housing assembly to be disassembled. The connector assembly is constructed using a small number of parts, thereby maintaining low maintenance costs while yielding a sturdy structure. A puller can be added to the connector assembly to improve access in congested connectivity applications without increasing the size profile. Chamfered front faces afford a degree of alignment tolerance when plugging the connector assembly into an adapter. Features of the connector assembly can be implemented in both a duplexed housing version as well as a paired simplex clipped version.
摘要翻译：光纤连接器组件结合了改善结构刚性和传输信号完整性的特征。这些功能还允许在高密度连接环境中轻松访问连接器组件。这些特征也促进了用于反转连接器组件的极性的技术，而几乎没有扭曲光纤的风险并且不需要拆卸壳体组件。连接器组件使用少量部件构造，从而维持低维护成本，同时产生坚固的结构。拔出器可以添加到连接器组件中，以改善拥挤连接应用中的访问，而不会增加尺寸配置文件。将连接器组件插入适配器时，倒角正面可提供一定程度的对齐公差。连接器组件的特点可以在一个双联壳体版本以及一个配对的单工夹紧版本中实现。

摘要： A socket assembly includes a rotor, a housing, and first and second conductors. The rotor includes a channel formed therein and defines an axis of rotation. The channel has a length about perpendicular to the axis of rotation and defines first and second ends. The housing receives the rotor such that the rotor is rotatable about its axis of rotation between first and second positions when secured therein. The housing includes a notch. The channel of the rotor aligns with the notch of the housing when in the first position such that first and second lamp pins can be received through the notch of the housing and into the channel of the rotor. The first conductor has first and second ends each disposed on opposite sides of the rotor. The first end of the conductor contacts the first lamp pin when the rotor is in the second position and the second end of the conductor contacts the second lamp pin when the rotor is in the second position. The second conductor is electrically isolated from the first conductor when the rotor is in the first position and is in electrical communication with the first conductor when the rotor is in the second position.
