20080249740 | Device to Determine the Road Followed By a Person on Foot - Device to determine the road followed by a person on foot, comprising at least three inertia sensors attached to the body of the person, one sensor to the torso and one sensor to each leg respectively, and which measure the absolute orientation of the part of the body concerned to which they are attached; a device which make it possible to determine the instant at which the person concerned takes a step; an arithmetic unit with which the sensors and the above mentioned means are connected, with arithmetic unit comprises a first algorithm which makes it possible, on the basis of a number of body dimensions of the person concerned and on the basis of the signals coming from the above mentioned sensors, to determine at least the step distance for every step as well as the cumulative step distance as of a certain starting point. | 10-09-2008 |
20080273194 | NON CONTACT WHEEL ALIGNMENT SENSOR AND METHOD - 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. | 11-06-2008 |
20110102779 | NON CONTACT WHEEL ALIGNMENT SENSOR AND METHOD - 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. | 05-05-2011 |
20120092654 | NON CONTACT WHEEL ALIGNMENT SENSOR AND METHOD - 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. | 04-19-2012 |
