    • A measuring device (11) for measuring the cone angle corresponding to a portion of a curved surface at a selected datum location. The device (11) is deformable to conform to curved surfaces and includes means such as surface indicia and a cursor to measure cone angle at that location. In the preferred form the device is in a circular sheet form including a first measuring zone portion (21) to measure spherical surfaces having cone angles of less than 360 degrees, and a second measuring zone (22) for measuring complex hyperbolic surface regions having cone angles of more than 360 degrees. The invention also relates to a method of using the device (11) to create two dimensional patterns for the measured three dimensional form.
    • 测量装置(11),用于测量与选定的基准位置处的曲面的一部分对应的锥角。 装置(11)可变形以符合曲面并且包括诸如表面标记和光标的装置以测量该位置处的锥角。 在优选的形式中,所述装置为圆形片形式,其包括用于测量具有小于360度的锥角的球形表面的第一测量区部分(21)以及用于测量具有锥体的复杂双曲面区域的第二测量区(22) 超过360度的角度。 本发明还涉及使用该装置(11)为测量的三维形式创建二维图案的方法。

    • A vehicle wheel alignment system and method is provided for performing a rolling wheel axis of rotation and wheel spindle point calculation every time an alignment is performed. Embodiments include an aligner having a target fixedly attachable to a wheel of the vehicle; a camera for viewing the target and capturing image data of the target; and a data processor. The data processor receives the image data from the camera, and determines a vector pointing from the target origin to a wheel spindle point based on the captured target image data, when the vehicle is rolled while the wheel is on a substantially flat surface such that the wheel and target rotate a number of degrees. The data processor is further adapted to calculate an alignment parameter for the vehicle based at least in part on the wheel axis of rotation and the coordinates of the wheel spindle point.
