Abstract: A method and apparatus are provided for aligning the wheels of a vehicle equipped with an electro-mechanical power steering system having a steering angle sensor, a torque sensor, and a torsion bar linking the steering angle sensor and the torque sensor. Embodiments include moving a steering wheel of the vehicle to a level position such that there is substantially no torque applied to the torsion bar; adjusting the toe of a first one of the front wheels of the vehicle after the steering wheel is moved to the level position; and moving the steering wheel substantially back to the level position, then re-adjusting the toe of the first one of the front wheels, when the steering wheel has moved more than a predetermined angle from the level position while adjusting the toe of the first one of the front wheels.

Abstract: A system and method for processing an acoustic input signal and providing at least one output acoustic signal to a user of a hearing-aid system. The hearing-aid system includes first and second channels with one of the channels having an adaptive delay. The first channel includes a directional unit for receiving the acoustic input signal and providing a directional signal; a correlative unit for receiving the directional signal and providing a noise reduced signal by utilizing correlative measures for identifying a speech signal of interest in the directional signal; and, a compensator for receiving the noise reduced signal and providing a compensated signal for compensating for a hearing loss of the user.
