  • Patent number: 11143557
    Abstract: A solution for reading detector arrays is disclosed. The solution comprises generating (400) an excitation signal, varying (402) the frequency of the excitation signal in time, supplying (404) the excitation signal to a detector array comprising a set of thermal detectors. The number of detectors corresponds to the frequencies of the excitation signal. In the solution, the signal is demodulated (406) at the output of the detector array and time-multiplexed base band signal is obtained. An analogue to digital conversion is performed (408) to the time-multiplexed base band signal and the base band signal is demultiplexed (410) to obtain a set of detector signals.

  • Patent number: 11129137
    Abstract: A method for selecting one or more resources for use from among a set of resources comprises obtaining (201) a first sub-set of the resources. The resources belonging to the first sub-set are the ones which have, according to occupancy information gathered over a long period of time, highest probabilities of matching requirements related to estimated usage time and/or needed capacity. The method further comprises selecting (202) a second sub-set from among the first sub-set of the resources on the basis of second occupancy information gathered over a short period of time. The resources belonging to the second sub-set are the ones from among the first sub-set which, according to the second information, have highest probabilities of matching requirements related to estimated usage time and/or needed capacity. The subsequent use of the long and short term occupancy information increases the probability of optimal selection.

  • Patent number: 11041540
    Abstract: A simple and robust suspension arrangement is provided for taking into account different suspension modes without the need for excessive sensoring or electronics. The novel suspension arrangement includes a first suspension element, which directly suspends the object to the frame, and a second suspension element, which suspends the object to the frame through a magnetic coupling between the object and the second suspension element. The magnetic coupling provides a magnetic coupling force (Fh) to act as a threshold such that the suspension arrangement is designed to magnetically decouple the second suspen-sion element from the object when the excitation force (Fe) transmitted be-tween the frame and the object exceeds the magnetic coupling force (Fh).
