Abstract: In a method for correcting a calibration table T(n,k) of a CT apparatus that contains calibration values, the CT apparatus having a detector system with N≧2 rows of detector elements following one another in the z-direction that include a first active row of detector elements in the z-direction and a last active row of detector elements in the z-direction, for correcting the calibration values of the aforementioned first and last active rows of detector elements, a reference vector R(k) is produced, the error is determined with respect to the first and last active rows of detector elements, and the error F(n,k) of the first and last active rows of detector elements is subtracted from the corresponding calibration values of the calibration table T(n,k) for determining corrected calibration values Tcor(n,k) with respect to the first and last active rows of detector elements.

Abstract: The present invention is configured to determine the weight of a payload of a mobile machine. When the machine is in motion, a force characteristic of the machine is compared with a force characteristic threshold, or range. The payload determination is based upon the force characteristic comparison, and the pressures sensed in at least one of the struts.

Abstract: A method for downloading and managing a test tool of a test system is proposed, which is applied to the test system having a test service server and a tested machine. A test tool required for performing a test for the tested machine is available as being downloaded from the test service server through a network, which connects the tested machine and the test service server, so as to examine if the tested machine works properly. As such, the test service server acts as a reservoir for the test tools and is used to activate start-up for the test, allowing the tested machine to be initiated with test conditions and user conditions for using the test tool being inputted to the test tool.
