Abstract: A method for detecting a vital sign of a subject (102) comprises: receiving (302) a reflected radio frequency signal from the subject (102), the reflected signal being based on a transmitted signal, which is Doppler-shifted due to mechanical movements corresponding to the heart rate and/or the respiratory rate; dividing (304) a baseband signal into a sequence of sliding windows (200), each sliding window (200) representing a time interval; estimating (306) a vital sign parameter in at least one sliding window (200); determining (308) whether a vital sign parameter may be reliably estimated in at least one sliding window (200); on condition that the vital sign parameter may not be reliably estimated in a sliding window (200), determining (310) a vital sign parameter of the sliding window (200) based on vital sign parameters estimated in a plurality of windows representing time intervals close to the time interval of the window (200).

Abstract: The present disclosure relates to a memory hierarchy for a system-in-package. An example memory hierarchy is connectable to a processor via a memory management unit arranged for translating a virtual address sent by the processor into a physical address. The memory hierarchy has a data cache memory and a memory structure having at least a L1 memory array comprising at least one cluster. The memory structure comprises a first data access controller arranged for managing one or more banks of scratchpad memory of at least one of the clusters of at least the L1 memory array, comprising a data port for receiving at least one physical address and arranged for checking at run-time, for each received physical address, bits of the physical address to see if the physical address is present in the one or more banks of the at least one cluster of at least the L1 memory array.

Abstract: The present disclosure describes methods and devices relating to electrode holding arrangements for bioelectric use. An example electrode holding arrangement includes a piece of flexible material configured to be fixed to a body part and at least one electrode spring element. The at least one electrode spring element is created by cutting out a certain geometric profile from the piece of flexible material. When the piece of flexible material is fixed to the body part having a body tissue surface, and an electrode is attached to the at least one electrode spring element and is positioned on the body tissue surface so that the body tissue surface generates a first force that makes the electrode spring element protrude outside a horizontal plane of the piece of flexible material, the at least one electrode spring element generates a second force that presses the electrode against the body tissue surface.
