Abstract: A motion theater system includes a theater floor defining a platform opening and a motion platform disposed therein. The motion platform carries a plurality of seats on an upper platform surface and is supported by a motion apparatus operable to impart rotation, heave, pitch, and roll. A gap fill arrangement is movable between a raised position filling a gap between the motion platform and the platform opening to provide a flush boarding surface, and a retracted position allowing free motion of the platform. A recessed portion of a theater wall defines a performance area selectively concealed or revealed by a movable curtain that may also serve as a projection surface. In some embodiments, the motion platform is rotatable through 360 degrees, and pitch or roll motions are perceived differently by an audience depending on rotational orientation.

Abstract: An improved adjustable desktop that is portable and mobile, that supports current technological needs of users (e.g., computer equipment) and that provides for different ranges of height adjustment (e.g., low-to-the-floor for children and greater spacing from the floor for adults). The desktop includes a working area with an end portion, a vertically adjustable support member pivotably coupled to the end portion and a manual actuator coupled to the vertical support. The manual actuator is disposed above both the working area and the vertically adjustable portion of said vertical support member allowing for easy adjustment of the vertical height of the work surface.

Abstract: The present invention teaches, describes, enables, illustrates and claims an improved adjustable height working area that is portable and mobile, that supports current technological needs of users (e.g., computer equipment) and that provides for different ranges of height adjustment (e.g., low-to-the-floor for children and greater spacing from the floor for adults). In addition, the present invention may also be configured to accommodate all variety of chairs, including wheelchairs, for users of the table. The present invention provides an easy to reach height adjustment mechanism that imparts force to assist adjustment of the height of the working area and the imparted force is adjustable by the user so that very heavy objects placed on the table are adequately supported during adjustment of the height of the table. Finally, the improved table of the present invention is compact during shipment and delivery to the user, and is easy to assemble and operate.
