Abstract: A dual function mobile station is constructed with first input and first display, which are used in the first functional mode, and second input and second display that are used in the second functional mode. The orientation of the mobile station in the second mode of operation is transverse to the orientation of the mobile station in the first mode of operation.

Abstract: The objective of the invention is a mobile station (30) that is used in a communication system. According to the invention the mobile station comprises first input means and first display means (23), which are used in the first functional mode, and second input means (31, 32) and second display means (33) that are used in a second functional mode. The mobile station has additionally a first part (201) and a second part (202), which can be moved relative to each other. The first input means and display means (23) and the second input means (31, 32) and display means (33) are situated in the first part (201) and the second part (202) in the following way: In the first functional mode the user surface of the mobile station comprises the first input means and the first display means (23) and in the second functional mode the user surface of the mobile station comprises the second input means (31, 32) and the second dislay means (33).

Abstract: The invention relates to a controlled source of current (1) having an inductive load (3), particularly a gradient coil adaptable to a nuclear spin imaging assembly. In order to cut down the reversal time of a current flowing in the load, the circuit is provided, according to the invention, with controlled energy storage instruments (2) connected in series with source of current (1) and inductive load (3) for increasing the rate of conversion of energy stored in said inductive load (3). Said instruments (2) preferably comprise capacitor means (C1, C2) and switch means (F1 . . . F4) for controlling the capacitors, facilitating a quick transfer of energy into or out of load (3). Said switch means (F1 . . . F4) are controlled by means of instruments (6) sensing a current flowing in inductive load (3), the conversion of energy being thus accurately controlled.
