Abstract: The present invention generally relates to articles for masking internal components of a motor vehicle steering column from the view of an occupant when the steering wheel is titled, or extended. Some embodiments relate to methods for making or using masking articles, or to methods for masking the internal components of a motor vehicle steering column when the steering wheel is titled, or extended.

Abstract: A method and apparatus for determining and removing the error in the SPS measurement of the Global Positioning System due to ionospheric delay. The disclosed technique utilizes semi-codeless technique to provide high accuracy GPS measurements. The delay of the P code is varied and the signals are cross correlated until a maximum value is reached. When the cross correlation of the L1 and L2 signals is at a peak value, the relative delay between the L1 and L2 signals is proportional to the ionospheric delay. The derived ionospheric delay may be accounted for in measurement analysis of the L1 signal to provide for a high precision position solution. The semi-codeless correlator also provides the L1-L2 carrier phase measurement for wide-lane applications.
