Abstract: A paired simplex fiber optic connector assembly comprises a clip that holds two simplex LC connectors together to yield a duplex connector that can be plugged into a duplex adapter. In some embodiments, the two simplex connectors are held in place by rails formed on both sides of the clip. In other embodiments, a side arm is formed on each side of the clip, the side arm comprising a hub that extends from the clip and a non-circular flange formed on the end of the hub. The flange is configured to engage with channels formed on the sides of the simplex connectors, thereby holding the simplex connectors in place. The simplex connectors are attached to the clip by rotating the connectors about the flange, thereby engaging the channels with the flanges.

Abstract: Multi-pole and single-pole circuit breakers include a housing and a reset lockout mechanism disposed within the housing. The reset lockout mechanism disables electrical communication between line and load terminals of the circuit breaker if a predefined condition exists. Some circuit breakers include a single actuator, transition between ON and OFF states, and are capable of performing test functions.

Some circuit breakers including a reset lockout mechanism may be powered only on its line side. Some circuit breakers provide an electrical indication when they are in the OFF state.

Abstract: Two-wire dimmer operation includes controlling conduction of power to a lighting load. In one aspect, based on a conduction angle adjustment, power supply voltage is monitored and a maximum conduction angle is established based thereon. In another aspect, a dimming level signal is received and a dimming level for a dimmer is set based on the received dimming level. The dimming level signal indicates a desired dimming level for a dimmer, and a maximum value for the dimming level signal is based on a dimmer power supply voltage. In yet another aspect, based on detecting an adjustment to increase a conduction angle of a dimmer, the conduction end angle is increased and the conduction start angle is also increased. This results in a net increase in the conduction angle for controlling operation of the dimmer.

Abstract: A wall-mounted enclosure assembly utilizes insertable door mounting components that allow the enclosure door to be easily mounted to the enclosure main housing without the use of tools and in a manner that easily sets the door installation depth to match the depth of the surrounding drywall. After the enclosure main housing is mounted in the wall, insertable mounting components that serve as hinges and latches for the door are inserted into slots formed on the vertical sides of the main housing. The insertable mounting components can be inserted to a desired depth but cannot be withdrawn from the slots until a release tab is pressed. The installation depth of the hinges and latches is correctly set to match the thickness of the drywall merely by inserting the insertable mounting components until a stopping surface on the components abuts the drywall.

Abstract: A hermaphroditic connector for use in single or multiple twisted-pair connectivity applications is constructed using a small number of parts having a simple but durable assembly. The connector housing comprises an elongated form factor that, when mated with a similar hermaphroditic connector, forms a rigid overlapping shield around the electrical contacts of the two connectors. While unmated, the conductive tines within the connector have a default curved profile that facilitates reliable connectivity with tines of a mating connector. When the connector is mated with a similar connector, the tines are deformed to a flatter profile by support plates within the connectors, yielding a shape more conducive to high-frequency signal applications. The shape of the tines also yields multiple in-line redundant contact points to ensure reliable connectivity without adding to the width of the connector.
