  • Patent number: 8794970
    Abstract: This disclosure describes novel aircraft control systems for propeller-driven training aircraft, and methods for their use. In an aspect of some embodiments, a control system might comprise an integrated power control that takes a single power input from the pilot and translates that input into controls for a throttle, a propeller pitch setting, and a fuel/air mixture. In another aspect of some embodiments, a glass cockpit may be provided, with computer displays emulating the instruments of the aircraft for which the pilot is training. Advantageously, this allows a pilot in training to learn, from the beginning, the power controls and/or instrumentation for the aircraft for which the pilot is training, instead of having to learn one power control and instrumentation system, only to later have to learn another system. In a specific embodiment, the instrumentation displays may be reconfigurable, allowing the displays to emulate those of a variety of jet aircraft.

  • Patent number: 7119789
    Abstract: A user can selectively engage some part or all of the haptic display of a haptic interface device to produce an enhanced interaction with an environment with which the user interacts using the haptic interface device. Further, the haptic interface device can be implemented so that the part of the haptic display that is engaged can be engaged to varying degree. The degree of engagement with the haptic display (together with whether part or all of the haptic display is engaged) determines the manner in which the haptic display is experienced by the user. The selective engagement with the haptic display is enabled by adding a haptic clutch model to the underlying haptic model used to produce the haptic display, the haptic clutch model engaging some part or all of the haptic model in response to user input. The addition of a haptic clutch model to the haptic model used to produce a haptic display provides a richer user interaction than is provided by a haptic display produced by the haptic model alone.

  • Patent number: 6443733
    Abstract: Enhanced realism of a real-time simulator having multiple computer-controlled units results from making the units capable of reacting to only those other units that each of them can be aware of because of their spatial relationships to the unit. Awareness is based upon probabilities; it can persist after a relationship changes; and it can be influenced by a unit's designation of a target. Each unit selects a target based upon a score incorporating multiple aspects of its tactical situation, and can change targets when the situation changes. A unit selects a strategy in response to which of a set of tactical configurations exist between the unit and its target; the strategy can change short of completion when the configuration changes. A plan produces guidance commands from the high-level strategy. The guidance commands are converted into control settings for guiding the subject unit using a physics engine for simulating the physical dynamics of the unit.

  • Patent number: 6281651
    Abstract: A haptic pointing device includes a plurality of rigid, elongated proximal members, each connected to a separate rigid, elongated distal member through an articulating joint. The other end of each proximal member is coupled to an actuator such as a motor, causing that member to swing within a separate plane perpendicular to the shaft of the motor in response to a control signal. An end-effector is interconnected to the second end of each distal member through an articulating joint, such that as the actuators move the proximal members, the end-effector moves in space. In a preferred embodiment, the device includes at least three proximal members and three distal members, and the end-effector is coupled to a user-graspable element such as a stylus which retains a preferred orientation in space as the members are driven by the actuators.

  • Patent number: 6094188
    Abstract: A method and apparatus is disclosed for transmitting data about an object within a defined field and using the transmitted data to generate a virtual object on the display screen of a computer. In one embodiment of the present invention the object used to transmit input data is a wireless glove assembly. The glove assembly supports a transmitting device which transmits data bursts, containing position and gesture information, in the radio frequency wavelength to four stationary receivers. The received signal is converted to a digital signal and input to a microprocessor control unit. The software used in the microprocessor control unit uses an averaging method to generate a virtual object on the computer display screen. The position of the virtual object is calculated based on the strength of the signal received. The movement of the virtual object on the computer display screen is in the same direction as and is proportional to the glove movement.

  • Patent number: 5678889
    Abstract: A modular assembly of theater seats aligned in a row. Each of the seats in the row moves with an identical motion in response to a coordinated sequence to create seat motions which can complement a scene being protrayed on a movie screen. Three or more rotatable shafts run along the row under the seats. The shafts are caused to rotate by hydraulic cylinders coupled to the shafts through bell cranks. Each seat is supported by three legs which are also coupled to the shafts by bell cranks. Rotation of the shafts causes vertical motion of the legs, and by coordinating the motions of the individual legs, in the presently preferred embodiment of the invention, the seats can be made to move with linear vertical motion, or to rotate either side to side or fore and aft in the vertical plane. Linear fore and aft motion of the seats may be provided by a fourth rotatable shaft running along the row under the seats.
