Abstract: The embodiments relate to a method and to a device having at least one source, (in particular, having a source for a magnetic resonance imaging system), wherein the device is designed to select a supply voltage of the source on the basis of a load voltage of a load supplied with current and/or voltage from the source.

Abstract: A detuning apparatus for a receive coil for a magnetic resonance device includes a number of coil elements. The coil elements may be selectively connected to a receive channel of a data processing apparatus by way of a switching apparatus. Each of the coil elements includes at least one detuning assembly such as, for example, a PIN diode that may be switched between a detuning state and a receive state by way of a continuous switching signal. A controller is provided to switch the switching apparatus and to generate the switching signals. The detuning apparatus has first diplexers connected upstream of the switching apparatus for injecting switching signals for switching the detuning assembly for coil elements to be detuned dynamically. The detuning apparatus also includes detuning modules for each of the coil elements to switch the detuning assembly to the detuning state if there is no switching signal present.

Abstract: The embodiments relate to a control device for transmission of at least one command. The control device includes at least one RFID transponder unit for transmission of an identification code and a read device for reading out the identification code of the RFID transponder unit. The RFID transponder unit is disposed within a medical device and has at least one initiation device for initiating the at least one command. In one embodiment, the control device includes three alarm units for triggering different alarms, such as after initiation of the at least one command, after interruption of a transmission link, and after a charging value of an energy storage unit has fallen below a threshold value.
