As illustrated in FIGS. 7 and 8, electrical component 595 may be connected via electrical members 601 (e.g., DC wires) to a contact 602 that may be a DC pick-up spring contact.
[0053]Returning to FIG. 7, base cover assembly 575 may also include a bearing 615 (e.g., a center bearing such as an internal bearing plate). Bearing 615 may be supported by a plurality of support members 618 (e.g., bearing retainers that may include a base bearing clamp 617 and an upper bearing clamp 619 as illustrated in FIG. 8). Returning to FIG. 7, base cover assembly 575 may also include a plurality of cavities 620 that may be tree stand cavities (e.g., valleys). The plurality of cavities 620 may be configured to receive 3-legged stands, 4-legged stands, and/or any other suitable configuration of stands. FIG. 7 illustrates cavities 620 having housing bottoms forming the cavities that extend toward the viewer (e.g., as viewed by the viewer). Base cover assembly 575 may also include a wall member 625 (e.g., vertical lip) forming an exterior wall of base cover assembly 575. Additionally, system 500 may include a Wi-Fi/Bluetooth system having a communication component 635 such as a receiver (e.g., a Wi-Fi/Bluetooth receiver) that may be similar to communication component 435 and an audio component 640 (e.g., a speaker of an audio system) that may be similar to audio component 440. Communication component 635 and audio component 640 may be connected to electrical component 595 and/or directly to each other.
[0054]FIG. 8 illustrates a cross-sectional view of sections A-A labeled in FIG. 6 and B-B labeled in FIG. 7. As illustrated in FIG. 8, a bottom of base cover assembly 575 (e.g., as illustrated in FIG. 7) may be disposed on (e.g., mated on) a top of base assembly 505 (e.g., as illustrated in FIG. 6).
[0055]FIG. 9 schematically illustrates a circuit diagram of an exemplary disclosed circuit of system 500 of FIGS. 6-8, including base assembly 505 and base cover assembly 575 (e.g., forming a rotary artificial stand base). As illustrated in FIG. 9, the exemplary disclosed circuit of system 500 may include electrical component 545 that may be connected to a bottom of base assembly 505 and may be in electrical contact with one or more contacts 530 (e.g., attaching to circular conductor surfaces having spring-loaded contactors) carrying current to electrical component 595. Electrical component 595 may include an electronics box where the AC electricity con
