This invention relates to a vehicle comprising an antihydroplaning system, particularly for improving the wheel adhesion despite the presence of a sheet of water on the road. Output signals from sensors for detecting body and chassis vibrations, ambient temperature and other parameters are analyzed to determine when hydroplaning is occurring or about to occur, and to activate antihydroplaning measures.

In an NMR apparatus with a system of gradient coils for the production of a magnetic field gradient within a measurement volume (1) within a field coil, the transverse gradient coils are constructed unsymmetrically with respect to the z=0 plane dividing the measurement volume (1), however largely mirror symmetric to a x=0 or y=0 plane containing the z axis, and possess only two partial coils (20', 20''; 40', 40'') whose windings each exhibit the same winding direction. The axial gradient coils are cylindrically symmetric with respect to the z axis and totally unsymmetric with respect to the z=0 plane, and consist of at least two partial coils which are arranged on differing sides of z=0 plane, whereby the partial coils on one side largely exhibit the opposite winding direction than the coils on the other side, and whereby the number of coils with a particular winding direction is not equal to the number of coils with the opposite winding direction. In each case, it is thereby achieved that the measurement volume (1) is displaced to a, relative to the z axis, axial end of the apparatus so that access to the measurement volume (1) is substantially improved.

A method of identifying a control element of a telecommunication system as well as a telecommunication system and a control element for executing this method. The telecommunication system has a plurality of control elements, wherein the control element are connected via respective predefined ports with respective predefined Ethernet switches of a communication network connecting elements of the telecommunication system. The control element sends a request for determining its identification to an Ethernet switch. The Ethernet switch determines the position of the control element in the communication network based on the position of the Ethernet switch within the communication network and based on the port, the control element is connected with the Ethernet switch. It replies position information to the control element. The control element uses an identification based on the received position information for identifying the control element against other elements of the telecommunication system.

The present invention pertains to a supply unit for accommodating medical instruments. A middle part, which is located at an instrument (12) and is equipped with lateral guide surfaces (3), engages a height-adjustable middle part of the supply unit (1) with side cheeks (2) in an accurately fitting manner. So-called end position sensors (4), e.g., photoelectric cells, which send a signal to an evaluating and control unit when the height-adjustable middle part of the supply unit (1) has been moved upward to the extent that pins (14) arranged there are completely accommodated by complementarily designed pin mounts (15) at the middle part of the instrument (12), are provided at the middle part of the supply unit (1). The evaluating and control unit now releases a plug-type connection for the power supply (6, 7), for the data transmission (8, 9) and for the pneumatic supply (10, 11).

The invention concerns a method of identifying a control element (31 to 40) of a telecommunication system as well as a telecommunication system and a control element (31 to 40) for executing this method. The telecommunication system has a plurality of control elements, wherein the control element (31 to 40) are connected via respective predefined ports (63 to 67; 73 to 77) with respective predefined Ethernet switches (21, 22) of a communication network (1) connecting elements (3, 31 to 40) of the telecommunication system. The control element (31) sends a request for determining its identification to an Ethernet switch (21). The Ethernet switch (21) determines the position of the control element (31) in the communication network (1) based on the position of the Ethernet switch (21) within the communication network and based on the port (63), the control element (31) is connected with the Ethernet switch (21). It replies position information to the control element (31). The control element (31) uses an identification based on the received position information for identifying the control element (31) against other elements (3) of the telecommunication system.

摘要:
A gradient coil system comprises a gradient coil for generating a rapidly changing magnetic gradient field in a working volume of a magnetic resonance apparatus, with a current path guided in windings on the surface of a geometric body, the geometry of which results in the desired spatial dependence of the magnetic field of this gradient coil in the working volume. N current power supplies (NG1, NG2) can be controlled with an analog or digital control signal to each generate a time-dependent controlled electric current (i1, i2) proportional to the control signal. The current path is divided into several parallel conductor paths which are electrically insulated from one another, and which form a doubly or multiply wound transformer, wherein the inductances of the various conductor paths with respect to one another as well as the mutual inductances with respect to one another have approximately the same value L. The ends of each conductor path are each connected to one respective current power supply (NG1,NG2), and the current power supplies (NG1, NG2) can be controlled with control signals in such a manner as to supply the same current (i1, i2) to the conductor paths at all times. This enables operation of a gradient coil with several current power supplies in such a manner that, should the dependencies of the currents of the current power supplies not be precisely identical, generation of disturbing magnetic fields having a geometry which differs considerably from the desired geometry for the gradient coil is prevented.
