Abstract: A racking for storing articles having guiding tracks and a rail vehicle, which may be moved on the guiding tracks for storing and retrieving the articles, wherein the guiding tracks merge in an intersection area. Within the guiding tracks there are formed current bars and at the rail vehicle there are formed current receivers engaging with the current bars and supplying the rail vehicle in the guiding tracks with energy. The intersection area is free of current bars. The rail vehicle has an intersection sensor, which is configured to detect whether the rail vehicle is within the intersection area. The vehicle control is configured to switch the rail vehicle, on the basis of the signals of the intersection sensor and the voltage in the guiding tracks, into different operation modes.

Abstract: A method of installing a software application image, for a software upgrade, within a remote and embedded target device includes the step of storing both a current and an upgraded software application image within an EEPROM within the target device. The set of instructions embodied within the current application image is maintained within the target device, while a validation operation is performed with respect to a set of instructions embodied within the upgraded software application image. Only once complete installation and successful execution of the upgraded application image have been validated is the upgraded application image designated as a current application image, and the previously installed application image discarded. Accordingly, the risk of the target device being a rendered unbootable as a result of the installation of a software upgrade is reduced.
