Abstract: A method for manufacturing a plastic composite uses recycled thermoplastic material comprising the steps of (1) providing flakes of thermoplastic materials to be recycled; (2) mixing the thermoplastic flakes, thereby forming a thermoplastic matrix having a first melting temperature; (3) forming or providing a web-structure of a predetermined thickness from fibers having a second melting temperature higher than the first melting temperature; (4) evenly distributing the thermoplastic matrix of thermoplastic flakes over the web-structure; (5) optionally forming or providing a second web-structure and placing it over the thermoplastic matrix; (6) optionally repeating steps (4) and (5); and (7) heating the web at a temperature between the first and second temperature using a thermoforming process.

Abstract: A method of determining alignment characteristics of a tire and wheel assembly mounted on a vehicle comprises projecting a light plane onto the tire and wheel assembly to form a reference illumination line, receiving a reflected image of the reference illumination line with a photo electric device, and determining a reference distance from the reference illumination line to a noncontact wheel alignment sensor including the photo electric device. The method also includes projecting a plurality of light planes onto the tire and wheel assembly to form a plurality of generally parallel illumination lines, receiving a reflected image of at least some of the generally parallel illumination lines with the photo electric device, and identifying which generally parallel illumination lines are imaged at the receiving step using the reference distance, and determining the orientation of the tire and wheel assembly based on the reflected image of the generally parallel illumination lines.

Abstract: A sensor and method of determining the orientation of an object, such as the alignment characteristics of a tire and wheel assembly mounted on a vehicle, includes projecting a plurality of light planes from a first light projector onto a tire and wheel assembly to form a plurality of generally parallel illumination lines on a tire of the tire and wheel assembly, receiving a reflected image of at least some of the illumination lines with a photo electric device reflected from the tire at an angle relative to a projecting angle of the first light projector, and determining a plane defined by spatial coordinates from a selected point located on each illumination line imaged by the photo electric device, with the plane representing the orientation of the tire and wheel assembly.

Abstract: The motion of a pedestrian is evaluated by determining at least one position of at least one identified portion of the pedestrian, projecting the positions(s) on at least one plane, and deriving the motion from the position(s) projected on the at least one plane. Typically the position(s) are determined in three-dimensions, e.g. of the feet. It is possible to project on two different planes to provide three-dimensional navigation information.
