  • Patent number: 7530929
    Abstract: A motion platform system includes a support and a motion platform supported by the support and rotatable about a plurality of bearing axes The motion platform is further rotatable with respect to the support about at least one axis that is offset from the plurality of bearing axes. The motion platform may include an intermediate frame supported by the support, where the intermediate frame is rotatable about a first bearing axis with respect to the support. The motion platform may further include an inner frame supported by the intermediate frame, where the inner frame is rotatable about a second bearing axis with respect to the intermediate frame. Rotations of the inner and intermediate frames about the first and second bearing axes facilitate rotation of the inner frame with respect to the support about at least one axis offset from the bearing axes.

  • Patent number: 7331226
    Abstract: A force measurement system includes an effector device with a hollow interior, an inner support secured within the hollow interior of the effector device, and at least one sensor secured at a selected location to the inner support and configured to measure a force applied to the inner support. At least one outer surface portion of the inner support is coupled with at least one interior surface portion of the effector device such that forces applied to the effector device are at least partially transferred to the inner support for measurement by the sensor.

  • Patent number: 7121982
    Abstract: A computer interactive isometric exercise system includes an effector, a sensor coupled at a selected location on the effector to measure a force applied by a user to the effector, where the applied force effects a strain on the effector, and control circuitry. The control circuitry includes a processor that receives and processes data corresponding to applied force information measured by the sensor for transference to a host computer. The processed data is transferred in a format compatible with the host computer and facilitates user interaction with the host computer in response to effector manipulation by the user. A plurality of effectors may further be combined together to form a system frame that provides a variety of isometric exercises for the user in combination with user interaction with the host computer.
