The end portion (5a) is in this way fixedly held during cleaving of the fiber (5). A method is also provided for cleaving an optical fiber (5), in which the fiber (5) to be cleaved is clamped using light-radiation-curing adhesive (11), as well as use of a fiber cleaving device (1).

Abstract: A method for determining a spoiler gradient of a magnetic resonance (MR) system is provided. At least one shim parameter that defines a shim magnetic field for compensating for B0 magnetic field inhomogeneities in a measurement volume of the MR system is received. As a function of the at least one shim parameter, at least one spoiler parameter that defines a spoiler gradient for canceling out a transverse magnetization is determined. The spoiler gradient is applied together with the shim magnetic field in a measurement of the MR system.

Abstract: In a method and apparatus for generating corrected magnetic resonance measurement data in an examination region of an object undergoing examination, a magnetic resonance sequence is applied to a subject in order to acquire magnetic resonance measurement data from an examination region within a time period. A first resonant frequency of nuclear spins in the examination region is determined at a first time point within the time period. A second resonant frequency of nuclear spins in the examination region is determined at a second time point within the time period. Magnetic resonance measurement data that are acquired at a further time point within the time period are corrected, based on the first resonant frequency and the second resonant frequency.

Abstract: A steering wheel for controlling steering movement of a vehicle has a steering wheel hub for mounting the steering wheel on a vehicle, a steering wheel rim, and at least two spokes, which connect the steering wheel rim to the steering wheel hub. The spokes can be telescoped by a drive and the steering wheel rim can thereby be slid relative to the steering wheel hub toward the axis of rotation of the steering wheel. The drive has a single drive motor for controlling at least two spokes.

Abstract: An apparatus for and method of removing a protecting synthetic coating (1) from an elongated element (2) in the form of an optical fiber (3) surrounded by the coating wherein a cut (8) is created into the coating by knife edges (6). The element is displaced with respect to the knife edges in the longitudinal direction of the element for displacing coating material (17) by the knives. At least one drop of liquid (12) with wetting properties is supplied to the cut for being sucked into a space created between the coating and the optical fiber during the displacement for acting as a lubricant for sliding the coating along the fiber to remove the coating from the fiber.

Abstract: A method for MR spectroscopy includes the steps of (a) switching at least one phase coding gradient for spatial coding of a spectral information to be detected, and (b) detection of the spectral information, and repeating (a) and (b) until a predetermined raw data space has been scanned. Specific spectral information is detected in (b) when the at least one phase coding gradient respectively has a value of 0. This specific spectral information is evaluated in order to determine a property of the spectral information already detected in (b), or still to be detected in (b).

Abstract: A method for cleaving thin rods of glass or quartz with a rod cleaving blade (27) and body (28) carrying the blade, is provided. The body (28) is of material varying in length through application of electric and/or magnetic fields. Driving force (31, 33) achieves relatively steady movement of the blade (27) towards a desired cleaving point and relatively steady small-amplitude vibratory component of movement towards and away from the cleaving point superimposed to the relatively steady movement, by influencing the body (28) electrically and/or magnetically. The blade is driven to vibrate with a frequency below 1 kHz during cleaving operation.
