Abstract: A vehicle diagnostic display unit including a case, a display screen disposed within a front portion of the case, and a main support coupled to a side of the case and having a finger compartment for receiving a user's fingers to allow the user to lift the vehicle diagnostic display unit using one hand. A navigation pad is disposed on a front surface of the main support and the main support is configured to allow a user to simultaneously lift the diagnostic display unit and access the navigation pad with a thumb. The unit also includes a fingerprint identification system including a scanner for scanning an image of a fingerprint of the user. The scanner is fitted on the navigation pad so that the user's thumb naturally rests on the fingerprint scanner when the user lifts the diagnostic display unit and accesses the navigation pad with the thumb.

Abstract: A method of determining a type of corrective weight for application to an edge of a rim of a wheel for correcting imbalance of the wheel, including measuring dimensions of an edge of a rim of a wheel to produce measured dimensions, comparing the measured dimensions to actual dimensions of different types of rim edges, determining a type of rim edge the wheel has based upon the comparison between the measured dimensions and the stored dimensions, and indicating a type of corrective weight appropriate for application to the edge of the rim of the wheel based upon the type of rim edge determined.
