A linear actuator comprises a motor for producing a bi-directional rotational output. A casing is connected to the motor at a proximal end, the casing having an inner cavity defining a joint surface. A shaft is within the inner cavity of the casing and actuated by the motor for rotation. A sliding tube is at least partially in the inner cavity of the casing for moving in translation in an axial direction relative to the casing. One or more travelling nut is connected to the sliding tube assembly for moving with the sliding tube in the axial direction, the travelling nut being operatively engaged to the shaft for converting a rotational motion of the shaft into a translation of the sliding tube. A liner is between the sliding tube and the joint surface of the inner cavity, an inner surface of the liner defining longitudinal contact surfaces separated by longitudinal grooves, the longitudinal contact surfaces contacting the sliding tube.

A portable theater includes a plurality of individual panels assembled together to form a theater enclosure, a plurality of audience seats installed within the assembled theater enclosure, and a projection screen mounted within the assembled theater enclosure. The projection screen has a partial toroidal shaped reflective surface configured to reflect, toward the plurality of audience seats, a moving image as projected by a projector.

The invention relates to a multisensory case comprising at least one odor-diffusing device consisting of at least one odor-diffusing support and a ventilator as well as a device for generating an air flow. The odor-diffusing device and the device for generating an air flow are arranged one above the other. The invention also relates to an immersive device comprising a screen and at least two multisensory cases, each case comprising at least one device for generating air flows and a sound-generating device, and to a control device designed to manage the emission of sound and air by independently controlling each of the cases.

Provided is an information processing apparatus that gives a rendition effect using an artificial intelligence function while a user is viewing and listening to content. The information processing apparatus that controls an operation of an external device of a display with use of an artificial intelligence function includes an acquisition unit that acquires a video image or an audio output from the display, an estimation unit that estimates the operation of the external device synchronized with the video image or the audio with use of the artificial intelligence function, and an output unit that outputs an instruction of the estimated operation to the external device. The external device is a rendition device that outputs a rendition effect on the basis of the estimated operation.

Light emitting displays can be used in cinemas for cinema presentations that integrate a sound system to achieve immersive conditions in cinema theatres. The cinema screen can include a matrix of light emitters and a diffuser sheet. The matrix of light emitters is configured to form a light-emitting area of the cinema screen. The diffuser sheet includes one or more perforations, and can be positioned between the matrix of light emitters and an audience area in the theatre. The diffuser sheet is positioned with respect to the matrix of light emitters such that the one or more perforations are configured to prevent light outputted by the light emitters from being viewable in the audience area.

A motion simulator for an entertainment system has a movable platform with one or more viewing positions and a supporting element for spectators to lean against. The platform is mounted on a support so as to have limited movability. A drive for moving the movable platform relative to the support has a cable drive fastened on the one hand to the support and on the other hand via at least one attachment point to the platform. An energy storage device is fastened between the support and the platform. The drive device pivots the platform about a pivot axis oriented substantially orthogonally to a central axis. The attachment point of the energy storage device and the point(s) of the cable drive device to the platform are arranged between the first pivot axis and the front face. The energy storage device pushes against the bottom face of the platform.

The interactive theater system is executed on an interactive gaming computer (IG PC) configured to execute an interactive multi-player video game. The IG PC outputs a video stream to a display system, such as a projector and screen, which allows the players to view the multi-player video game. Each player sits in a multi-sensory seat for providing multi-sensory feedback to each player during execution of the interactive multi-player video game. The player provides input using an input device having an infrared camera and motion sensors. The infrared camera is used to image an infrared light arrangement positioned above-the multi-sensory seats. Infrared camera data and motion sensor data is used by the IG PC to accurately determine the real time position of each input device. Players in a first interactive theater system can compete with players in a second interactive theater system in real time.
