  • Patent number: 6543570
    Abstract: A steering gear (12) has a rack bar (36) and a housing (22). The rack bar (36) is movable linearly relative to the housing (22) for turning steerable wheels (68) of the vehicle. Movement of the rack bar (36) relative to the housing (22) is resisted by friction. An electric motor (14) is connected with the rack bar (36) and causes linear movement of the rack bar (36) relative to the housing (22). A controller (16), in response to a vehicle speed signal and a torsion signal, generates a motor control signal for controlling the electric motor (14). The controller (16) stores data indicative of the friction resisting movement of the rack bar (36) relative to the housing (22) of the steering gear (12). The controller (16) modifies the motor control signal to compensate for the friction.

  • Patent number: 6540652
    Abstract: A cushioning conversion machine (20) for converting sheet-like stock material (22) into a three-dimensional cushioning product (P) including a device (400; 400′; 500; 600; 600′; 700) which controls the width of the strip and which may be selectively adjusted to change the width of the strip. By selectively setting the device (400, 400′, 500; 600; 600′; 700), a cushioning product of a desired width may be produced. For more sophisticated packaging needs, the stock material may be converted into a first portion of a certain width, the device adjusted, and then the stock material may be converted into a second portion of a different width whereby the cushioning product will have continuous portions of different widths.

  • Patent number: 6536550
    Abstract: A mounting assembly for adjustably securing an axle and a brake carrier to a front monofork of a motorcycle. The axle is received within an eccentric axle carrier and extends through a lower end of the brake carrier. An opposite end of the brake carrier includes an opening through which a carrier mounting device extends. The carrier mounting device is secured to the monofork and guides or aligns the brake carrier relative to the monofork. When the axle carrier is rotated to adjust the attitude of the motorcycle front end, the mounting device moves relative to the brake carrier while the brake carrier is maintained in a relatively fixed relationship to the wheel.

  • Patent number: 6494476
    Abstract: A method and apparatus for controlling the steering of a trailing section of a multi-sectioned vehicle is described. The trailing section follows the path of the first section. Data is acquired by a controller from sensors on the various sections. The controller then processes this data, generating a configuration needed for the controller-steered wheels to follow a path approximately equivalent to the path taken by the first steered section. Power is then applied by some means to steer these controller-steered wheels, forcing them into the desired configuration. The complexity of the control system can be varied with different algorithms providing alternative steering patterns as desired. This system can be extended with more trailing sections without necessitating more than minor changes to the control algorithms.
