  • Patent number: 10728978
    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: 20200136324
    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.

  • Patent number: 10591143
    Abstract: Employing capacitors as shunts in a decorative light string can prevent the circuit from being opened when a lamp burns out or becomes loose in the socket. But manually assembling such a light string is costly and the quality of the resulting string is not assured to be high. The present disclosure introduces a shunted light string, and a method of assembling that light string that is able to be automated to ensure a consistent quality level by reducing or eliminating human workmanship issues.

  • Patent number: 10375091
    Abstract: A method, device and assembly are disclosed herein. Each of the method, device and assembly, in an embodiment, is operable to perform multiple steps for protecting a network, including adding resources to a blocklist if the resources satisfy a blockage condition. After a maturation period expires, the steps include determining whether the blocked resource is listed on a blacklist. The addition to the blocklist corresponds to a precautionary event, and the presence on the blacklist corresponds to a threat event. The steps include determining a correlation of the precautionary events to the threat events, and changing or adjusting the blockage condition as a result of the correlation outcome differing from a correlation target factor by a designated amount.
