Shaker control device
First Claim
1. A device for generating simulated environmentally caused vibrations in a steering wheel, which comprises:
- a steering wheel;
a frame attached to the steering wheel;
an electric motor mounted on said frame, said motor having a rotor;
an electrical circuit for driving the motor when the vibration is to be simulated;
a first shaft connected to said rotor so as to be rotationally driven by said motor; and
a first weight disposed on said first shaft in a radially asymmetric configuration with respect to the longitudinal axis of the shaft so that the asymmetric weight configuration vibrates the shaft when the shaft is rotationally driven by the motor to thereby simulate environmentally caused vibrations in said steering wheel.

Abstract
A device for causing the steering wheel of a video-based vehicle simulator to selectively vibrate during predetermined periods of the video sequence includes a frame which is rigidly attached to the steering wheel. A cylindrical electrical motor is mounted on the frame, and a first shaft is attached to one base of the motor and extends outwardly from the motor. Also, a second shaft is attached to and extends outwardly from the other base of the motor, and the second shaft is coaxial with the first shaft. The two shafts can be rotated by the rotor of the motor. Each shaft has a weight attached to the shaft. These weights are attached to their respective shafts radially asymmetrically with respect to the axis of the shafts. One weight is attached to its shaft on one side of the axis of the shafts, and the other weight is attached to its shaft on the side of the axis which is opposite from the first weight. A microprocessor is electrically connected to the motor to selectively energize the motor during predetermined periods of the game sequence. When the motor is energized, the rotation of the weights causes the motor to vibrate. The vibration of the motor is transferred through the frame to the steering wheel.
