    摘要： Disclosed is a weighing device (1) which comprises at least one weight preparation table (16, 17) and a weighing pan (14) functionally connected to a load cell. The at least one weight preparation table (16, 17) and the weighing pan (14) are displaceable relative to each other along at least two linear axes (x, z), wherein a first one of the at least two linear axes is a horizontal axis (x) and a second one of the at least two linear axes is a vertical axis (z), and wherein displaceability is restricted to purely linear translational displacement along the at least two linear axes. A horizontal displacement is such that the at least one weight preparation table is positionable at at least two different positions relative to the weighing pan (14). In a first one of the at least two different positions, the at least one weight preparation table is laterally offset from a centre (18) of the weighing pan in a vertical view. In a second one of the at least two different positions, the at least one weight preparation table is overlapping the centre of the weighing pan in the vertical view. The weighing pan and the at least one preparation table are enclosed within a weighing chamber (11) of the weighing device, wherein the weighing device is configured to restrict any motion of the at least one weight preparation table, if any, and of the weighing pan, if any, to within the weighing chamber. Further disclosed are a system comprising the weighing device and a method for weight determination.

    摘要： The present invention relates to a method for diagnosing erroneous distance measurement of a laser rangefinder unit 1, 105-109 due to pollution, in particular in the field of product dimensioning. The method comprises a step of transmitting a continuous laser light beam 7 onto a detection surface 20 by operation of a laser transmitting unit 4 of the laser rangefinder unit, a step of receiving by a radiation sensor unit 5 of the laser rangefinder unit a superposition of laser light reflected from the detection surface 20 and laser light reflected from a polluted region 30 in the path of the laser light beam 7, a step of determining a phase difference between a reference phase and a phase of the laser light received to thereby derive a signal indicative of an influence of the laser light reflected from the polluted region 30 on the phase difference, and a step of diagnosing erroneous distance measurement due to pollution when said signal is in fulfillment of a failure criterion. The invention relates further to a laser rangefinder unit and a computer program for carrying out said method.
