    Abstract: A track-based swing ride system providing passengers a unique swinging ride experience. The ride system includes a ride track that supports a moving bogie coupled to the ride track that includes a drive assembly driving the bogie along a ride path defined by the ride track. The ride apparatus includes a pendulum arm pivotally coupled at a first end to the bogie, whereby the pendulum arm is suspended below the ride track and moves along the ride path with the bogie. The ride apparatus includes a passenger vehicle coupled to a second end of the pendulum arm opposite the first end of the pendulum arm. To provide the swinging sensation, the ride apparatus includes a roll driver rotating, concurrently with the drive assembly of the bogie, the pendulum arm about a roll axis extending through the first end of the pendulum arm.

  • Patent number: 9914262
    Abstract: A print method for printing three dimensional (3D) objects that are difficult to copy by use of a 3D scanner and 3D printer. The printer includes a print head with an extrusion nozzle with a heated portion and a print bed with a surface for receiving material extruded from the extrusion nozzle. The printer includes a print material supply spool loaded with an anti-scanning filament. The method includes operating the print head to draw the anti-scanning filament into the heated portion for heating and to extrude the heated filament from the extrusion nozzle to form a 3D object. The printed 3D object includes one or more scan protected exterior surfaces on at least one element of the 3D object. The scan protected exterior surfaces are either light absorbing or reflect light in unconventional directions. The anti-scanning filament is a plastic mixed with an anti-scanning additive such as a retroreflective material.

  • Patent number: 9656428
    Abstract: A method for operating a three dimensional (3D) printer to limit unauthorized copying and provide authentication of 3D objects printed from authorized models fabricated on 3D printers. The method includes providing a digital file defining a 3D model of an object to the 3D printer. The 3D model includes a model of an identification (ID) element. The method includes processing the digital file to define print layers of the 3D model, and a number of the print layers include layers of the model of the ID element. The method involves operating the 3D printer to print the layers to form a 3D object with an integrally formed ID element. The ID element is embedded within object elements of the 3D object. The integrally formed ID element may be a radio frequency ID (RFID) tag providing identification data when read by an RFID reader scanning the 3D object.

  • Publication number: 20160067740
    Abstract: A three dimensional (3D) for printing a 3D object without the need for printing support structure for overhanging or cantilevered portions of the 3D object. The 3D printer includes a print head with a nozzle for extruding print material and a build plate with an upper surface receiving the print material extruded from the nozzle, whereby the 3D object is formed on the upper surface of the build plate. The 3D printer includes a tilt adjustment mechanism tilting the build plate about at least one axis to orient the upper surface and the 3D object relative to the nozzle during the extruding of the print material. The tilting can be performed such that a previously extruded portion of the print material is vertically aligned with the nozzle to receive the print material extruded to form an overhanging element of the 3D object.

  • Publication number: 20160067922
    Abstract: An apparatus for building a three dimensional (3D) object using volumetric addition. The apparatus includes a print chamber containing a volume of a curable resin. The apparatus includes a first and second curing energy sources outputting first and second beams of energy. The apparatus includes a controller operating targeting mechanisms to align the beams of energy to sequentially intersect at a plurality of curing positions associated with build volumes of a digital model of the 3D object. The energy sources may be lasers generating a desired amount of heat when their beams are crossed. The curable resin may be a heat-curable fluid curing when heated into a curing temperature range, and the amount of heat provided by intersected pairs of the first and second beams heats volumes of the heat-curable fluid, proximate to each of the curing positions only, to a temperature in the curing temperature range.

  • Patent number: 9174704
    Abstract: A passenger boat configured for interactively shielding passengers from incoming water. The boat includes a hull with seats for receiving passengers and a rider interactive assembly with an input element for receiving input from the passengers. The boat also includes a water shield supported on the hull and an actuation system operating in response to the input from the passengers to move the water shield from a first position to a second position relative to the seats. In some cases, the water shield is mounted on the hull to travel within a channel extending about a perimeter of the hull located on an outboard side of the seats. Then, the water shield may include a wall that extends substantially vertically from the channel.

  • Patent number: 9120021
    Abstract: An interactive system adapted for lean-based control of ride or video game experiences. The system includes a vehicle seat and a motion base with a vehicle base upon which the vehicle seat is mounted. The system includes an actuator assembly moving the vehicle base and seat. A control system interprets sensor input signals and generates control signals to operate the actuator assembly to move the vehicle base and seat. Force sensors positioned in the vehicle seat sense forces applied by the passenger to the vehicle seat and transmit sensor data signals to the control system. The control signals operating the driver assembly are generated based on the sensor data, which is output from left and right sensors provided in a bench of the vehicle seat as well as in a front and a back support to provide X and Y-axis values based on passenger leaning in the vehicle seat.

  • Patent number: 8890892
    Abstract: A computer-implemented method for generating images. The method includes receiving first and second target images. The method further includes computing a delta image based on a difference between the first target image and the second target image and a technique for multiplexing a first display image with the delta image, where the first display image multiplexed with the delta image, when viewed by a person in an ambient setting, is perceived as the second target image. Advantageously, a hidden image is obscured from an ambient observer, while still providing the ambient observer with a target image that is intended to be perceived.

  • Patent number: 8858351
    Abstract: A ride or show control apparatus using visual recognition to provide a more interactive experience to guests or participants. The apparatus is adapted for operating a ride or show element, such as a robotic character. The apparatus includes a mechanized or robotic element with movable components positioned near a guest traffic area. The apparatus includes an imaging assembly capturing images of the traffic area and outputting digital image data. A controller is provided that includes a processor using an object recognition module to process the image data to determine whether an object is in the traffic area. In response to the object recognition, the control system operates movable components of the mechanized element such as to cause it to speak or move in the direction of the recognized object such as a visitor's face or a badge, hat, or other item worn or carried by a guest or participant.

  • Patent number: 8831255
    Abstract: An augmented reality (AR) audio system for augmenting environment or ambient sound with sounds from a virtual speaker or sound source positioned at a location in the space surrounding an AR participant. The sound from the virtual speaker may be triggered by an action of the listener and/or by the location or relative orientation of the listener. The AR audio system includes stereo earphones receiving an augmented audio track from a control unit, and binaural microphones are provided to capture ambient sounds. The control unit operates to process trigger signals and retrieve one or more augmentation sounds. The control unit uses an AR audio mixer to combine the ambient sound from the microphones with the augmentation sounds to generate left and right ear augmented audio or binaural audio, which may be modified for acoustic effects of the environment including virtual objects in the environment or virtual characteristics of real objects.
