Abstract: A Christmas tree decorative enhancing system provides a lighting display that is choreographed to an audio file and respective output. Each of a series of light strands are in signal communication with a respective output port on a controller. The controller integrates a storage device reader, a digital audio decoding integrated circuit, an operational controller data file decoding circuit, an output controller circuit, and a power regulation circuit. An audio data file is merged with an operational controller data file and stored in a portable digital data storage device. The controller decodes the merged file, generates an audio output signal, and drives the output controller circuit to illuminate one or more light strands in a choreographed manner in concert with the audio output. Two or more systems can be in wireless, signal communication to operate in tandem. The system can be provided using the light strands to form a tree-shape, or the lights can be placed into an existing tree.

Abstract: A pipe coupling assembly includes a pair of casing members each having a first end including a first continuous exterior surface edge defined by a first radius, and a second end including a second continuous exterior surface edge defined by a second radius. The first radius is smaller than the second radius so that a tapering, continuous, exterior surface extends therebetween. A gasket is to be positioned adjacent first and second pipe sections, and within the pair of casing members. A sleeve has a tapering interior surface to be positioned over the tapering, continuous, exterior surfaces of the pair of casing members. The second end of at least one of the pair of casing members includes a sleeve locking tab extending outwards from the second continuous, exterior surface edge so that the sleeve is lockable in position surrounding the pair of casing members by engagement with the sleeve locking tab.
