Abstract: An actuated support frame for transmitting motion to a seat with respect to a ground as a function of motion signals associated with video output, comprises a frame. The frame is expandable/retractable along translational degrees of freedom. Support surfaces are provided on the frame. The support surfaces are displaceable with respect to one another by expansion/retraction of the frame so as to be sized to support a seat. Actuators are provided between the frame and the ground. The actuators receive signals and selectively displace the frame with respect to the ground in synchronization with a video output, whereby a seat supported on the frame is displaceable within the frame. A method for installing a seating system of a motion simulator system is also provided.

Abstract: A motion simulator for transmitting motion with respect to a floor as a function of motion signals associated to a video output. The motion simulator comprises a seating portion for accommodating a viewer viewing the video output. Actuators each have a first member and a second member interrelated by a degree of freedom. Each of the actuators has a degree of actuation connected to the seating portion for displacing the first member with respect to the second member along the degree of freedom as a function of actuation from the actuators in relation to the motion signals. The first member of each of the actuators is secured to the seating portion The second member of each of the actuators comprises a leg supporting the motion simulator on the floor, whereby the seating portion is movable as a function of actuation from the actuators.

Abstract: The system produces movements in a home entertainment chair. It has a motor controller and a plurality of movement generator units for generating small amplitude and low frequency movements in the viewers chair according to desired effects. A synchronization is achieved using an audio/video stream.

Abstract: The system produces movements in a home entertainment chair. It has a motor controller and a plurality of movement generator units for generating small amplitude and low frequency movements in the viewer's chair. The system is intended for home use and can be easily installed under each leg of a chair or of a sofa or at the corners of a platform. The source of movement control signals can be derived from a video presentation soundtrack, and directional movement sensations can be created by inducing controlled movements in each leg of the viewer's chair.

Abstract: The present invention is concerned with a method for the extraction of magnesium from magnesium-containing materials such as magnesite, dolomite and silicates materials like serpentine residues, products from the amphibole or pyroxene group. The magnesium-containing material is first leached in at least one leaching reactor, and subsequently submitted to a series of neutralizing steps in separate reactors under controlled pH and oxydo-reduction potentials. The slurry produced is filtered to produce a substantially pure magnesium chloride solution containing less than 1 ppm of each contaminant present therein.
