An unfolding springing apparatus comprises a base, an apparatus linkage comprising cranks and coupler links connected to the base, a biasing element, a drive motor, a transmission, and a prop mount. The apparatus linkage includes one or a plurality of opposed pairs of cranks, each pair of cranks being connected to each other at their respective ends by a pair of pivotally connected coupler links. The biasing element is operative to bias the apparatus linkage to fold or unfold. The drive motor is operative to unfold or fold the apparatus and to reenergize the biasing element. The transmission includes a linear extension module. When engaged, the transmission transmits displacement of the drive motor to the apparatus linkage to unfold or fold the linkage. When disengaged, the transmission releases the apparatus linkage to be folded or unfolded by the biasing element. The transmission includes a motorized clutch module.

Disclosed is a method and device for directing a lighting effect that induces dynamic effects by using a masking layer. The method and device for directing a lighting effect may selectively control emission of a plurality of light emitting devices based on a masking layer, thereby inducing dynamic imaging effects such as moving images in a direction object, and may achieve the direction having a high degree of freedom by directing the direction position, size, or rotation of an object during a performance direction in a performance hall.

Disclosed is a method for controlling digital content playback and a wireless lighting device. The method controls playback of the media data, and controls transmission of the lighting control data to the wireless lighting device based on a relevant event of the media data playback.

Systems and methods herein are directed to providing a visual effect background that may be added behind a transparent holographic projection screen (e.g., of a Pepper's Ghost Illusion system) that provides for greater scenic depth behind the holographic projection, regardless of the amount of actual physical space behind the transparent screen. The background, which may be used for projection-based holographic projections or video panel display projections, generally establishes an optical illusion of depth behind the holographic images (producing a depth perception or “perspective” that gives a greater appearance of depth or distance behind a holographic projection).

An instantaneous heater (51) is mounted in a casing (20) of a smoke machine (10). The instantaneous heater (51) includes a heating rod (52), a flow guiding member (131) mounted around the heating rod (52), and an outer tube (64) mounted around the flow guiding member (131). The flow guiding member (131) includes an inner periphery (137) abutting an outer periphery (58) of the heating rod (52). A shallow, rectilinear heating passage (151) is defined in the inner periphery (137) of the flow guiding member (131) to permit a small amount of oil to pass therethrough. The oil can be directly and completely heated and vaporized by the heating rod (52) into smoke.

A wind direction indicator for hunters includes a smoke generator, a housing, an electrical power source, an air pump and a switch all arranged such that the indicator may be actuated by a hunter using a single hand. The smoke generator may be a cartomizer as an example.

A three-dimensional display system includes a first display and a second display spaced apart from the first display having one or more light sources configured to emit light and to illuminate the first display, where the first display is at least partially transparent such that the second display is visible through the first display. The three-dimensional display system includes a special effect system disposed at least in part between the first display and the second display and is configured to be activated to cause a special effect to be visible through the first display. The three-dimensional display system includes a controller communicatively coupled to the first display, the second display, and the special effect system.
