  • Publication number: 20130209079
    Abstract: A camera system includes a body defining a cavity therein, and a camera attached to the body within the cavity and including a lens. The camera system also includes a shape memory alloy transitionable between a first state and a second state in response to a thermal activation signal, and a wiper configured for wiping debris from the lens. The wiper is attached to the camera and is actuatable by the shape memory alloy. The shape memory alloy transitions between the first state and the second state to actuate the wiper so that the wiper contacts and translates across the lens and thereby wipes debris from the lens.

  • Publication number: 20130211677
    Abstract: Methods and systems are provided for suppression of steering wheel vibrations generated by periodic disturbances in a vehicle steering system. An exemplary method reducing steering wheel vibrations caused by periodic disturbances involves determining a gross torque attributable to the periodic disturbances in the steering system, identifying a desired amount of suppression of the vibrations at the steering wheel, determining an offset torque based on the gross torque and the desired amount of suppression, and generating a motor command signal in a manner that is influenced by the offset torque. The motor drive command signal is provided to an electric motor coupled the steering wheel and/or the vehicle tires, and the motor drive command signal influences the torque applied by the motor to assist steering of the vehicle tires by the steering wheel in a manner that attenuates the vibrations communicated to the steering wheel by the desired amount.
