Abstract: The present technology provides an extendable pillar having a lower section with a base column, and an upper section with an upper column. The base column includes a ratchet mechanism that operates with a fastener rod in the upper column. When the ratchet mechanism is in a locked position, the position of the upper section is fixed. When the ratchet mechanism is in an open position, the upper section can slide along the base column to extend or compress the length of the pillar. In certain embodiments, the upper column and the base column include friction connection mating components. The friction connection mating components cooperate to allow the upper section to slide along the base column when a sufficient force is applied to the upper section, while supporting the upper column at a fixed position when the force is removed.

Abstract: A remote-controlled decoration includes a decorative main body and a remote controller. The decorative main body includes an internal chamber, and a base mounted to a lower open end of the chamber. The base is provided with a circuit board connected to a power source, at least one LED light, and a receiver. The remote controller includes a signal transmitter for remotely transmitting a control signal to the receiver on the decorative main body, so as to control the LED light to light or extinguish.
