  • Publication number: 20200396707
    Abstract: The present invention relates to a node for use in a sensor network, e.g. for use in radar systems, using the antenna elements in each separate node as antenna elements in an array antenna configuration. The node transmits and receives signals over a first and a second communication channel having non-equal speeds of propagation. When the node identifies that a reset signal has been received over the first communication channel (S10), it adjusts the internal clock (S11), transmits an acknowledgement signal (S12) and initiates an acknowledgement process (S17). When the reset signal has not been identified, the node transmits the reset signal over the first communication channel (S13) and receives a response signal from one node (S14). If the response signal is an acknowledgement signal, an acknowledgement process is initiated (S17), or if the response signal is a non-acknowledgement signal, the internal clock is adjusted (S16) and an acknowledgement process is initiated (S17).

  • Patent number: 10124684
    Abstract: An arrangement, system and method are described which enhance efficiency, reduce the stray field of wireless power transfer, and make use of special coil geometries for transmitter and receiver. The coil geometry is an approximation of a multipole current. Such currents have a faster decaying electromagnetic field compared to traditional coils. This allows higher power densities to be transferred.
