A linear actuator is configured to be connected between a platform and a structure or ground for displacement of the platform relative to the structure or the ground. The actuator comprises a base, and an output displaceable linearly relative to the base. A first plurality of idlers are on the base, and a second plurality of idlers are on the output. An actuator unit has a reciprocating rotational output. A tensioning member has a first end connected to the rotational output of the actuator unit, and a second end connected to an anchor point on one of the output and the base, the tensioning member being routed from the rotational output, through the first plurality of idlers and the second plurality of idlers and to the anchor point for converting a winding/unwinding of the tensioning member into a translation of the output.

The present disclosure provides methods and systems for synchronizing motion data with an audio/video stream. An audio/video stream, which comprises at least one timing marker, is obtained. The audio/video stream is processed to detect the at least one timing marker. Motion data associated with the audio/video stream and timing information for the motion data are obtained, the timing information including timing information regarding the at least one timing marker. The audio/video stream, with the at least one timing marker detected, and the motion data, are output with the timing information.

A joint assembly between a first component and a second component comprises a ball portion configured to be connected to the first component. A socket is configured to be connected to the second component or ground and comprises a socket base, a socket cover, and a spherical joint cavity within the assembled socket base and socket cover to receive the ball portion to form a spherical joint. At least one biasing member is in the joint assembly. A clamp clamps the socket base to the socket cover such that the at least one biasing member biases the socket base and the socket cover toward one another.

The present document describes a device and method for synchronizing a motion signal corresponding to a media content with a media signal for the media content, the motion signal being for controlling a motion feedback system. The method comprises: receiving a portion of the media signal; obtaining a fingerprint corresponding to the received portion of the media signal; from reference fingerprints associated with time positions of at least one reference media content, identifying a reference time position of the media content corresponding to the obtained fingerprint; obtaining the motion signal associated with the identified reference time position of the media content; and outputting the motion signal synchronized with the media signal using the identified reference time position of the media content for controlling the motion feedback system.

Media recognition and synchronisation to a motion signal

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 threaded shaft is within the inner cavity of the casing and actuated by the motor for rotation. A sliding tube assembly has a sliding tube in sliding arrangement with the inner cavity of the casing for moving in translation in an axial direction relative to the casing. A pair of traveling nuts is connected to the sliding tube assembly for moving with the sliding tube in the axial direction, the traveling nuts being operatively engaged to the threaded shaft for converting a rotational motion of the threaded shaft into a translation of the sliding tube, the traveling nuts being on opposite sides of a member of the sliding tube assembly connecting the traveling nuts to the sliding tube.

In a building equipped with a plurality of motion-enabled chairs such as a movie theatre, the vibration of the motion-enabled chairs adds up and may damage the foundation of the building especially at the resonance frequency. The present application describes a system and method for controlling the resulting vibration by introducing an alteration such as a delay or an inversion in the motion signals sent to the motion-enabled chairs. This delay causes the vibration of some motion-enabled chairs to be de-phased from the vibration of the other motion-enabled chairs. Whereby, the intensity (magnitude) of the resulting vibration is reduced. Control of the motion-enabled chairs may be done centrally through a central controller, or locally at selected motion-enabled chairs.

A method for synchronizing an output of a motion signal with a virtual reality program being played comprises mixing a multi-channel audio output of the virtual reality program into at least one mixed audio track. A time position of the virtual reality program being played is obtained using the at least one mixed audio track. A motion signal corresponding to virtual reality program being played and synchronized with the identified time position of the virtual reality program being played is obtained, the motion signal comprising motion platform actuator-driving instructions. The motion signal is output to an actuation system of a motion platform for producing vibro-kinetic effects in the motion platform corresponding to and synchronized with the virtual reality program being played. A motion controller for synchronizing an output of a motion signal with a virtual reality program being played is also provided.

A linear actuator comprises a motor having an output. An end block is connected to a casing and to the motor and has a counterbore at a distal end with a bearing seated and retained in the counterbore. A coupling assembly couples the output shaft of the motor to a threaded shaft for transmission of the rotational output to the threaded shaft. A sliding tube is in sliding arrangement with the inner cavity of the casing for moving in translation relative to the casing.

A system for providing motion signals indicative of a motion to be performed by the motion platforms synchronously with video images comprising an input interface for extracting a motion signal from the input signal. A server provides a network address to each motion platform. A motion platform interface has control ports connected to arrays of motion platforms. Each motion platform being connected one to another by a wired connection according to a control protocol. The motion platform interface individually actuates each of the motion platforms by providing a client motion signal to each motion platform comprising the motion signal with a respective network address. Each motion platform is managed according to a respective feedback signal comprising the provided network address of each motion platform.
