Abstract: Methods for positioning an FFT-window in an OFDM-receiver are disclosed as well as electronic apparatuses and computer program products for performing the methods. The method comprises determining a position of the FFT-window in relation to one or more OFDM-symbols of a received OFDM-signal, using the position of the FFT-window to obtain a first OFDM-symbol from the received OFDM-signal, and applying an FFT to the first OFDM-symbol to produce an FFT-output signal. The method also comprises determining a frequency dependent phase rotation component of the FFT-output signal, and removing the determined frequency dependent phase rotation component from the FFT-output signal to obtain a compensated FFT-output signal. A delay spread estimate is calculated based on at least one of the FFT-output signal and the compensated FFT-output signal, and the position of the FFT-window is adjusted based on at least the determined frequency dependent phase rotation component and the calculated delay spread estimate.

Abstract: A sliding window arrangement has an upper and a lower horizontal guide rail and a vertical rectangular window which is mounted between the guide rails and displaceable along the same. The window has at each upper corner a guide means which engages the upper guide rail, and at each lower corner a guide means which engages the lower guide rail. The lower guide rail has a stop means which is positioned so that the window, when on displacement towards a displacement end position it reaches this position, abuts against the stop means in its lower front corner and, owing to its kinetic energy, is tilted to a tilted position about an imaginary tilt axis extending perpendicular to the window. In the tilted position, the guide means located in the lower rear corner of the window is disengaged from the lower guide rail.

Abstract: A wall-mounted foldable airing or carpet-beating stand comprising an attachment bracket secured to the wall to support the inner end of a bar which in position of use of the stand assumes a horizontal position, and two support legs pivotally mounted in pivot points at the outer end of the bar. The bar is mounted for pivotal movement about a horizontal shaft in the attachment bracket. The shaft is displaceable in the vertical direction along slits or channels formed in the attachment bracket from or towards a lower operational position of the bar and an upper position of rest. In this position the bar may be pivoted to a vertical position.
