Abstract:
1. A medical examination or treatment apparatus, comprising: a controlling system for controlling one or more apparatus elements in a first examination or treatment apparatus located in a first room; at least one mobile operating element assigned to the controlling system and configured to communicate wirelessly with the controlling system for operating the first examination or treatment apparatus by transmitting operating signals; and at least one processing device configured to operate direction-selectively and/or frequency-selectively for modifying the operating signals transmitted by the operating element such that a second controlling system of a second examination or treatment apparatus arranged in a second room adjacent to the first room is not activated by the modified operating signals, wherein the direction-selective and/or frequency-selective device is a scrambler integrated into a building wall between the first and the second rooms, wherein the scrambler is configured to receive at least one of the following signals: a first operating signal intended just for operation of the first examination or treatment apparatus yet capable of causing an unintended operation of the second examination or treatment apparatus, the first operating signal passing through the building wall from the first room to the second room, and a second operating signal intended just for operation of the second examination or treatment apparatus yet capable of causing an unintended operation of the first examination or treatment apparatus, wherein the scrambler is further configured to modify a received first operating signal and a received second operating signal as each respective one of the first and second operating signals passes through the building wall so that the modified first operating signal is disabled from operating the second examination or treatment apparatus as said modified first operating signal propagates to the second room, and further so that the modified second operating signal is disabled from operating the first examination or treatment apparatus as said modified second operating signal propagates to the first room.
