Abstract: A demodulator (310) for a microwave radio link transceiver (110, 300), comprising an input port (311, 312) arranged to receive a radio signal (Din, Sin), a slicer module (313) arranged to detect an information signal (Sdet, 201) comprised in the received radio signal, an interference detection module (314) arranged to determine a difference signal as a difference between the received radio signal (Din, Sin), and the detected information signal (Sdet), wherein the interference detection module (314) is arranged to detect one or more interference signals (202, 203, 204) by identifying signal content comprised in the difference signal, the signal content being associated with a signal power (230) above a pre-determined threshold level (260, 261), wherein the interference detection module (314) is further arranged to associate at least one of the detected interference signals (202, 203, 204) with one or more respective identification features, and wherein the demodulator (310) comprises an output port (315) arran

Abstract: A multitube collimator for a camera, especially a scintillation camera, whose sensitivity and resolving power may be varied by changing the length, slope, dimension or shape of the tubes (10). This is achieved by that the grid at least at two opposed limiting sides is surrounded by guiding means (11) which are arranged to, by parallel movement and/or by moving towards or apart from each other, influence the collimator tubes (10) collectively referred to the positions of the tubes relative to the guiding means (11) and/or the dimension of the tubes in the longitudinal and/or transverse direction.
