Abstract: The invention relates to a data processing system with a first 1 and a second system unit 2, with a data transfer connector 4 provides a connection between the first and the second system unit, where the first system unit comprises an energy storage device 10 as a power supply and a monitor for monitoring a state of charge 11 of the energy storage device. The monitor is adapted to initialize the disconnection of the connection between the first and the second system unit when the state of charge falls below a threshold value.

Abstract: A method and system for the minimization of conflicting activities with respect to an object stored within a data processing system are disclosed. An object within a data processing system may be the subject of multiple activities by users of that system. A temporary record of all current activities with respect to an object is stored within a state mask which has been established in association with that object. Thereafter, prior to permitting a proposed activity, the state mask is utilized to automatically determine if the proposed activity represents a conflict with an existing activity.
