摘要： The invention relates to a laser alignment device (1), comprising holding means (2) for holding a laser and alignment means (3) for adjusting the holding means (2). According to the invention, the holding means (2) comprise a torsion body (4) and pulling and/or pushing means (15) by means of which at least two sections of the torsion body (4) can be deformed relative to each other by the application of a force such that the torsion body (4) can be twisted about an imaginary alignment axis (17).

摘要： The invention relates to an apparatus for measuring the pressure of a tire on a moving vehicle, comprising measuring means (14, 18, 24) which are provided on or inside a floor or ground so as to interact with the tire and which generate an electronically analyzable measurement signal in reaction to the tire driving over the measuring means, and analysis means (22, 40) which output a tire pressure signal corresponding to the tire pressure in reaction to the measurement signal. The measuring means include optical capturing means (18) for acquiring a tire width as the width of a tire footprint forming when the tire drives over the floor/ground. The analysis means are designed to determine a footprint length from a series of tire width data generated by the optical capturing means and/or from a pattern of a pressure measurement signal generated by the measuring means and to determine the tire pressure from a footprint area calculated as a function of the length and width of the footprint and from a force applied to the footprint area by the tire.
