The equipment testing the measurement accuracy of measurement points beneath vehicle frames is applicable to vehicle distortion measurement and alignment. At least four measurement heads (18), from various possible sites, are fixed in stable alignment with the vehicle raised. The centres of the two measurement traverses (12,14) are aligned w.r.t. their measurement heads as required, e.g. centrally, by transversely adjusting the heads. The measurement traverses are also aligned by vertical adjustment of their measurement heads w.r.t. themselves and horizontal adjustment of the heads w.r.t. each other. When satisfactory alignment is achieved, the vehicle is lowered and measurements made w.r.t. the established alignment.

A measurement device 1 for measuring a circumferential surface profile of a wheel 6 comprises a base 2 mounted at a position axially and radially fixed relative to the rotation axis of the wheel 6 and a probe 8a-c ending in a measurement head 10a-c. Measurement head 10a-c measures the radial position of a location on the surface profile relative to the rotation axis. Rotation of probe 8a-c relative to the wheel 6 allows it to detect variation in the measured radial position with distance around the surface profile. Base 2 may be removable such that the device can measure surface profiles of different wheels. Measurement head 10a-c may measure surface profiles of different diameters and/or may move in the axial direction relative to the base 2. Measurement head 10a-c may be contactless or may be a contact head biased to keep it in contact with the surface profile. There may be a reference probe 8b which measures the radial position of a location on the surface profile relative to the rotation ...

A golf ball having a plurality of recessed dimples on the surface thereof claim 1 , wherein at least a portion of the recessed dimples have a surface defined according to the method of . The present invention relates to a golf ball dimple cross-sectional profile based on the envelope of the response of an under damped harmonic oscillator.Golf ball dimples are known to have a significant effect on the aerodynamic forces acting on the ball during flight. For example, the dimples on a golf ball create a turbulent boundary layer around the ball. The turbulence energizes the boundary layer and helps it stay attached further around the ball to reduce the area of the wake. This greatly increases the pressure behind the ball and substantially reduces the drag. Based on the significant role that dimples play in golf ball design, manufacturers continually seek to develop novel dimple patterns, sizes, shapes, volumes, cross-sections, etc. Thus, the present invention provides a novel dimple cross-sectional profile having unique aesthetic and aerodynamic characteristics.In one embodiment, the present invention is directed to a method for defining a golf ball dimple surface.

The method and equipment relates to the measurement of deflections of filter sectors in a disc filter. The filter discs in the disc filter are constituted by a number of filter sectors, and the distance between a position fixed relative to the filter, most commonly the scraper itself, and the filter surface is conventionally measured by manual measurement methods. The equipment is instead used that has a measuring head with a quick-release coupling for its mounting fixed in the filter, and a position sensor in the measuring head that measures the distance between the measurement arrangement and the surface of the filter disc in order to form momentary measurement results. The momentary measurement results are transferred by a data transfer link from the measurement arrangement to a data collection unit PC that has a memory.

An apparatus for measuring feet, for the purpose of gathering measurements for custom shoes, is disclosed. The apparatus is shaped like a shoe, and has an opening where the shoe lace opening is normally present on the shoe, in addition to openings near the big toe and the little toe. Each opening has holes for laces that are tightened so that the gap, or overlap, of the openings can be measured. Additionally, mats of known thickness can be used to measure the distance between the heel of the shoe and the heel of the foot. Furthermore, markings are used to identify the different shoe lace holes so measurements can be taken at multiple places along the top of the foot.
