  • Patent number: 5341680
    Abstract: A driver measure system aids in determining the physical requirements of a disabled driver in order to modify a van or other vehicle to his or her specific needs. The driver measurement system comprises a frame including tracks for positioning a wheelchair and a control assembly which includes a steering wheel and hand controls. Force adjustment and measurement mechanisms for the steering wheel and hand controls enables a trained technician to evaluate the functional driving ability of the disabled driver. The simulator also provides a structural reference framework for taking anthropometric measurements. The measurements obtained are used to prepare a specification or "mobility prescription" for modifications and adaptive driving equipment needed to customize a vehicle.

  • Patent number: 5265686
    Abstract: A steering mechanism for a remotely-controlled golf caddie having a drive motor coupled to a steering assembly by a non-positive coupling. The non-positive coupling between the drive motor and the steering assembly allows the steering assembly to disengage from the drive motor when the caddie runs into an obstruction. Also, the steering mechanism uses a potentiometer assembly for allowing the caddie to center itself after receiving a command to turn left or right.
