  • Patent number: 12111042
    Abstract: Certain embodiments of the disclosed technology include a decorative lighting system that can be integrated with an artificial tree. The decorative lighting system may include a white light emitting diode (LED) light string and a variable-color LED light string. The variable-color LED light string may employ LED lamps having embedded Red, Green, and Blue (RGB) LEDs. The RGB LED lamps may include an embedded integrated circuit (IC) configured to communicate with and control the energizing of each of the corresponding RGB LEDs to create a multitude of colors and color combinations that can vary with time to create a light show. An electronic controller in communication with the LED lamps may allow a user to select the mode for the light show and further may provide a periodic reset signal to restart or re-synchronize the light show.

  • Publication number: 20240266789
    Abstract: A power transfer system to facilitate the transfer of electrical power between tree trunk sections of an artificial tree is disclosed. The power transfer system can advantageously enable neighboring tree trunk sections to be electrically connected without the need to rotationally align the tree trunk sections. Power distribution subsystems can be disposed within the trunk sections. The power distribution subsystems can comprise a male end, a female end, or both. The male ends can have prongs and the female ends can have voids. The prongs can be inserted into the voids to electrically connect the power distribution subsystems of neighboring tree trunk sections. In some embodiments, the prongs and voids are designed so that the prongs of one power distribution subsystem can engage the voids of another power distribution subsystem without the need to rotationally align the tree trunk sections.

  • Publication number: 20240191532
    Abstract: Disclosed is a container, such as an above-ground pool, with an improved porthole. The container can include a base, a side wall joined to the base, and at least one porthole. The porthole can comprise an aperture in the side wall and a generally transparent window sheet attached to the side wall and completely covering the aperture in the side wall. Such a design can be stronger and more durable than conventional portholes. The pool can also have portability and storability characteristics that are superior to those of conventional pools.

  • Patent number: 11901684
    Abstract: A connection system to facilitate the mechanical coupling, and the transfer of electrical power between, trunk sections of an artificial tree is disclosed. The connection system can include a mechanical coupling system having a guiding surface and a guiding slot on a first trunk section and a guiding protrusion disposed inside a second trunk section. Insertion of the first trunk section into the second trunk section and thus contact of the guiding protrusion against the guiding surface can cause the first trunk section to rotate relative the second trunk section until a predetermined rotational alignment is reached, aligning electrical contacts of first and second electrical connectors, each of which is attached to an outer wall of a respective trunk section. The electrical contacts of the first and second electrical connectors can establish electrical communication between the first and second electrical connectors, and thus between the first and second trunk sections.
