A haze-filled bubble device and method for producing haze-filled bubbles are provided that encapsulates a haze inside a rapidly emitted, continuous flow of bubbles, without permitting significant amounts of the haze to escape the device outside of the bubbles. Bubble solution is pumped into a bubble wand and a wiper cycles across its face to form a meniscus of bubble solution over the bubble wand's outer face. Additionally, a haze generating assembly can selectively pump fog fluid to a heater and a resultantly generated haze is provided to an enclosed chamber. A fan in the enclosed chamber forces the haze from the chamber into a conduit that channels the haze into the bubble wand and to the miniscus, where the air flow created by the fan is used to form haze-filled bubbles.

A projection apparatus includes a plurality of two-fluid nozzles, a projection-apparatus-side-gas-flow-path, a gas valve, a projection-apparatus-side-liquid-flow-path, a liquid valve, a projector, a mist concentration measurer, and a controller. The controller starts and stops spraying of a mist by controlling the gas valve and the liquid valve on the basis of an image or a video projected onto a screen from the projector. The controller receives a signal indicating a mist concentration from the mist concentration measurer, starts and stops spraying of the mist by controlling the gas valve and the liquid valve on the basis of the received signal, and thus controls the mist concentration.

An apparatus for monitoring and controlling a haze and/or particulate level in the air is disclosed. The apparatus comprises a detecting unit (sensor) and a controller. The detecting unit is configured to detect the haze and/or particulate level in real time. The controller in communication with the detecting unit is configured to receive data related to a haze level from the detecting unit. The apparatus further comprises a display and a control switch. The display in communication with the controller is configured to display data related to the haze level monitored by one or more sensors. The sensors are laser based particulate sensors. The control switch in communication with the controller is configured to send a signal to control a haze generator, thereby monitoring the haze level in real time and controlling the haze generator at predetermined time periods using the control switch for attaining and maintaining a desired haze level.

A special effects communication system may include a camera system at a first location that generates a first dataset based on one or more images or impressions of a first user at the first location. The special effects communication system may also include a control system communicatively coupled to the camera system and a special effects system. The control system may receive a second dataset corresponding to a second user present at a second location or to one or more users at one or more locations while the first user is present at the first location. The control system may also provide one or more control signals to cause the special effects system at the first location to generate special effects to present a visual and/or auditory likeness of the second user using special effects material and/or mediums.

The utility model discloses a bubble machine, comprising a housing and a film forming device, a liquid storage device, an air supplying device and a control device provided in the housing, therein the liquid storage device is provided with a first liquid storage chamber and a second liquid storage chamber, the second liquid storage chamber is provided below the first liquid storage chamber and is in communication with the first liquid storage chamber, the horizontal section of the second liquid storage chamber is smaller than the horizontal section of the first liquid storage chamber. The utility model fully utilizes the limited bubble liquid, avoids the waste of the bubble liquid, and increases the time of the single use of the bubble machine; in addition, the diffusion path of the bubble is more diversified and the retention time is longer.

The invention proposes an apparatus for generating three-dimensional visual effects, characterised in that it comprises, in combination: a controlled smoke generator (10) comprising a synthetic smoke source and a means for directionally propelling the smoke produced by the generator in order to form a plume of smoke extending in a certain direction, and a controlled light generator (20), suitable for generating one or more light beams in the plume of smoke and in the direction in which it extends, the light beam or beams being essentially contained in said plume of smoke. Application in particular to the production of lightsaber visual effects, and more generally to varied three-dimensional light effects.

The present invention relates to a spray apparatus and a method for controlling the spray apparatus in a system for controlling special effects in a 4D movie theater that are configured to spray water therefrom to provide rain and wind special effects, and more particularly, to a spray apparatus and a method for controlling the spray apparatus that are configured to drain the residual water remaining therein to the outside just after driving stops, while being engagedly operated with a content reproduced in a movie theater to provide rain and wind special effects for customers.

For the vehicles of an interactive fairground ride, in particular a rollercoaster, control consoles are proposed which are equipped with a control button and a display unit and are assigned to each passenger. These control buttons and, if appropriate, the display units of all the control consoles, are connected by means of a transmitter, by radio or by cable, to an evaluation and control unit which detects the reaction times for all passengers and calculates a mean value, the collective reaction time, therefrom. A signal for starting the vehicle is not generated until after the expiry of the collective reaction time. In a fairground ride of this kind, the emphasis is on the interaction between all the passengers of a vehicle.

An aerial show system for leveraging downwash and other forces to use an unmanned aerial vehicle (UAV) as a creative element in a show. UAVs in the aerial show system each include a propulsion and lift mechanism, which generates downwash as it moves the UAV about a show's airspace. The aerial show system also includes one-to-many show effect devices adapted to make use of the downwash to activate or animate one or more movable components to generate a desired show effect, e.g., a spinning propeller or fan on an object carried or tethered beneath the UAV chassis/body. The movable component would otherwise be static or passive and relies on the potential and/or kinetic energy created by the UAV in airspace for actuation or animation.
