Abstract: A method for detecting faults on an electrical line includes feeding a measurement signal to a first location on the line by using a measuring assembly, receiving a reflected measurement signal at the first location, and determining a fault location on the line on the basis of the period of time until the reflected measurement signal is received while considering a line attenuation. A reflection location on the line where the measurement signal is reflected is used, and the line attenuation is determined on the basis of the level of the reflected measurement signal received at the first location. A corresponding measuring assembly is also provided.

Abstract: An assistance system for a road vehicle which can be used on a roadway having one or more lanes, includes a position determination system for determining a lateral relative position of the road vehicle on the roadway. The position determination system has an electrical signal line disposed parallel to the roadway, a signal generator for generating and feeding an electrical signal into the signal line, resulting in a current flow which can be generated in the signal line, an on-vehicle sensor assembly for capturing a field strength and/or a field direction of an electromagnetic field forming about the signal line as a result of the current flow generated, and an on-vehicle evaluation unit, configured to determine, from the captured field strength and/or field direction, a lateral relative position of the road vehicle relative to the signal line. A more reliable position determination system is thus provided.

Abstract: The disclosure relates to a system for tracking the position of a target object. A marker arranged on the target object and an additional control marker are tracked by a tracking device secured to the robot arm. The control marker is arranged in a known specified three-dimensional positional relationship with the tracking device. During the tracking of the position of the target object, the specified three-dimensional positional relationship between the tracking device and the control marker is measured. In the event of a difference between the measured and the real specified three-dimensional positional relationship, a corresponding signal is generated depending on the difference.

Abstract: An apparatus checks for a presence of an electrically conductive body in the near field of charging coils of an arrangement for induced charging. At least one transmitting device provides a transmission signal in the form of a magnetic field. At least one receiving device generates a reception signal from the transmission signal and induced into the receiving device. The transmitting device and the receiving device are formed in such a way that, when the electrically conductive body is present, a first reception signal forms and, when the electrically conductive body is absent, a second reception signal, different than the first, forms in the receiving device on account of the induced transmission signal.

Abstract: A method for emitting a sequence of high frequency pulses that may have different envelopes in a magnetic resonance tomography system is provided. A digital instruction signal that specifies the envelope for the high frequency pulses that are to be emitted is received. A digital control signal is transmitted to a high frequency unit for generating high frequency pulses, depending on the instruction signal. A test signal that allows notification of a current overload situation is received. The current control signal is reduced if the test signal indicates an overload situation.

Abstract: An apparatus for checking for a presence of an electrically conductive body has at least one transmitting device and at least one receiving device. The transmitting device provides a transmission signal in the form of a magnetic field. The receiving device generates a reception signal from the transmission signal that is induced into the receiving device. The transmitting and receiving devices are configured in such a way that, when the electrically conductive body is absent, partial reception signals form in the receiving device on account of the induced transmission signal and the partial reception signals substantially cancel one another out in the reception signal.

Abstract: A two-channel magnetic resonance tomography system is provided with a regulation circuit for an amplification system in order to be able to take into account different load situations of the MRI system in a flexible and efficient manner. It is thus possible to improve the MRI measurements greatly if the MRI system is set to the respective load situation beforehand by an idle state measurement. The adaptation may optionally also be carried out during the MRI measurement. Therefore, a multiplicity of completely different load situations may be taken into account in an optimized manner by the regulation circuit.

Abstract: A network analyzer includes an n-port network with two ports for measuring wave parameters of a measurement object. Each port has a feed for a radio-frequency signal from a signal source. Signal components of the radio-frequency signal fed into the respective port are reflected at the measurement object and the signal components of one or more radio-frequency signals fed into at least one other port are transmitted through the measurement object to the respective port are measured as wave parameters. The two ports are supplied with different radio-frequency signals, wherein frequencies or frequency bands are offset with respect to one another by a frequency offset. Reflected and transmitted signal components of the radio-frequency signals are measured at the same time at the two ports.
