An enzymatically treated pasta dough having superior workability and machinability is provided by is prepared by treating pasta dough with an enzyme system consisting essentially of one or more pentosanase enzymes which are essentially free of both proteolytic and amylase activities. The floor mat is constituted by a series of small square sections and are connected together with connectors that permit easy deployment and removal of the mat system by detaching segments of the mat from each other. As a result, there is generated a measuring program that measures changes in the operating state of software in real time while reducing the effect on the operation of the software. The controller is programmed such that, when the operating request signal is present and the hatch is open, the controller outputs a pivot command to a closing system for closing the hatch only if the presence of an obstacle is not detected by the monitoring device for the hatch opening.
