Abstract: A clip separating system (1) is for separating a clip (3) from an accumulation of clips (3) contained within a feeding assembly (5). The clip separating system (1) includes a separating assembly (7) having an inlet (9) and an outlet (11), the inlet (9) of the separating assembly (7) being operatively connected to an outlet (15) of the feeding assembly (5) for receiving the clip (3) to be separated therefrom. A path (10) is defined between the inlet (9) and the outlet (11) of the separating assembly (7). The clip (3) to be separated is positively driven along the path (10) via a corresponding driving component (19) of the clip separating system (1). The outlet (11) of the separating assembly (7) is vertically offset (21) with respect to the outlet (15) of the feeding assembly.

Abstract: A networked lighting control device may include a switching device to control power to a load, a communication interface to couple the relay module to a control module at the relay panel, revenue-grade metering circuitry to monitor power flowing to the load, and a controller to control the switching device in response to inputs received at the communication interface and to transmit metrology data to the control module. A control module may include a mounting interface to mount the control module to a relay panel, a first communication port to receive first control inputs using a first protocol, a second communication port to receive second control inputs using a second protocol, a third communication port to control one or more relay modules mounted to the relay panel using the local communication format, and logic to translate the first and second control inputs to the local communication format.

Abstract: A captive panel fastener is manufactured by first overmolding a plastic cap around the head of a screw, the cap having a cylindrical plastic skirt extending downwardly beyond the base of the screw head and formed with a circular opening at the bottom. After a compression spring is placed around the shank of the screw, the screw is pressed against a top surface of a ferrule to a point where the capped-skirt extends downwardly below a ferrule flange. At that point, heat and pressure are applied radially inwardly around the periphery of the plastic skirt along its bottom edge until it is permanently deformed to a point where the bottom of the skirt is smaller in diameter than the ferrule flange. The screw is thereby captivated to the ferrule between extended and retracted positions.

Abstract: The computational resources of a digital power meter can be reduced by utilizing an interrupt requested in anticipation of interrupt latency to perform real-time tasks, an approximation of a root mean square load current at an earlier time to compensate for a phase shift between the load current and the current transducer output, and an amplitude that is neither zero nor maximum to distinguish the cycles of a harmonically distorted waveform.

Abstract: The data storage and processing resources required for an electric meter are reduced by basing the selection and application of phase error correction on a root mean square load current flowing through the meter.
