A motion base device for simulators is disclosed. In the motion base device, an upper plate is positioned above a base plate with a simulating cabin being carried on the upper plate. Three cylinder actuators are positioned between the base and upper plates so as to heave, pitch and/or roll the upper plate relative to the base plate. Of the three cylinder actuators being respectively placed at apexes of a regular triangle, the first one is fixedly mounted to the base plate and is jointed to the upper plate using a universal joint. Each of the second and third cylinder actuators is jointed to the base and upper plates using a universal joint and a joint block. A hydraulic pressure supply unit supplies pressurized oil to the three cylinder actuators so as to allow the three cylinder actuators to be independently operated.

A pneumatic motion platform is disclosed, adapted to allow an open center to handle shear stress without the need for a central support. In an embodiment, the platform comprises a deck; a base; a plurality of inflatable actuators, each actuator attached to the deck at a predetermined location intermediate the base and the deck, the plurality of inflatable actuators adapted for use as an active motive force with respect to the deck in a plurality of planes; a plurality of compliant stabilizers disposed intermediate the deck and the base, at least one portion of each stabilizer disposed proximate a predetermined one of the plurality of inflatable actuators; a fluid controller in fluid communication with the plurality of inflatable actuators; and a source of fluid in fluid communication with the fluid controller. A ride vehicle may comprise a cabin attached to a deck attached to the motion platform attached to a rotator such as a turntable. It is emphasized that this abstract is provided to comply with the rules requiring an abstract which will allow a searcher or other reader to quickly ascertain the subject matter of the technical disclosure. It is submitted with the understanding that it will not be used to interpret or limit the scope or meaning of the claims.

A riding device includes an intermediate base pivotally assembled on a bottom base and having the opposite ends respectively provided with a front and a rear vertical spindle. The front spindle has each end fixed with a crank, and the rear spindle has each end movably connected with a swing arm. The cranks and the swing arms have their upper ends respectively connected with four feet of a seat plate. A transmission unit fixed on the intermediate base includes a motor for driving a first, a second and a third gear to rotate. The third gear is secured on the front spindle. A pull rod has its upper end connected with the second gear by a universal bearing and its lower end connected with the bottom base. When the motor started, the seat plate can be actuated by interaction to swing back and forth, up and down and left and right.

A positive-feedback go/no-go control system for an electric-vehicle ride (10) at an amusement park reliably communicates motion commands, vehicle-presence signals, and vehicle-status signals in the presence of high electrical noise and does so without the addition of expensive add-on equipment. The railway electric-vehicle ride includes an outbus (16) and an inbus (18) running along a railway (14). The positive-feedback go/no-go control system comprises a wayside control board (22) that provides a bipolar pulse-width-modulated command signal (26) to the outbus. A control circuit (24) onboard the electric vehicle receives the bipolar pulse-width-modulated command signal, amplitude modulates it at different frequencies that represent the electric vehicle's intended action, and provides the processed bipolar pulse-width-modulated command signal (30, 32) to the inbus. The wayside control board receives the processed bipolar pulse-width-modulated command signal, bandpass filters the frequency components, and compares the filtered frequency components to predetermined thresholds to detect the presence and intended action of the vehicle.

A new interactive simulator ride for providing an entertaining interactive visual, audio, and motion simulation. The inventive device includes a guidance track comprised of a plurality of laterally spaced guidance rails, a simulator vehicle housing having an interior and having lateral side walls having a plurality of support wheels mounted thereon for supporting the simulator vehicle housing on the spaced guidance rails. A seat for seating by a person is provided within the interior of the simulator vehicle housing. A viewing screen is provided within the simulator vehicle housing interior for providing a computer generated visual image for viewing by a person located in the simulator housing. The invention also includes a projection means for projecting a computer generated visual image on the viewing screen, a means for providing computer generated visual images to the projection means, and a user input device. The input device provides input data from a person within the simulator vehicle housing to the computer generated visual images providing means. The input data represents a reaction to the visual images which the computer generated visual images providing means uses to modify the displayed visual images accordingly. Preferably, the projection means, the computer generated visual images providing means are provided within a multimedia computer included within the simulator vehicle housing.
