摘要： The embodiments relate to an image reconstruction to be carried out on a base unit of a MRI system, where data is formed by reception signals obtained by a local coil unit. Provisions are made for an alternating magnetic field, modulated in accordance with a reference clock, the alternating magnetic field to be used by the local coil unit for obtaining electric energy for supplying local electronics of the local coil unit and the reference clock to be retrieved from the received alternating magnetic field by the local electronics, a radio signal containing MRI information representing the reception signals and clock information representing the retrieved reference clock to be produced by the local electronics and transmitted to the base unit, and the received radio signal to be processed by the base unit such that the data and the clock information are retrieved therefrom and provided for the image reconstruction.

摘要： A method and an arrangement for determining the delay of a signal between a first station and a second station of the arrangement, with the aim of determining the spatial distance between the stations. A first series of first signal pulses is generated in the first station at a first pulse repetition rate f1. A second and a third series of second and third signal pulses is generated in the second station, comprising a second f2 and third pulse repetition rate f3, where f2=f1+Δf and f3=f1−Δf. The second and third series of second and third signal pulses are transmitted to the first station, where the series are correlated with the first series of first signal pulses. The delay of the signal can be determined from the time elapsed between two successive pulses of the signal arising from the correlation.

摘要： An arrangement for detecting bending deflection of a wind turbine blade is provided. The arrangement for the wind turbine includes a radio transmitter and a linear antenna array assigned to the radio transmitter. The radio transmitter is mounted on the blade tip and emits a signal. The antenna array is mounted on the rotor of the wind turbine in a co-rotating manner and receives the signal. On the basis of the transit times of the signal from the rotor to the individual antennas of the array, the position of the radio transmitter relative to the array is determined. In the event of blade deflection, for example when a high wind load is present, the relative position changes which is detected by the arrangement.
