  • Publication number: 20240056177
    Abstract: A method carried out in a UE (1) for estimation of a parameter of a communication link, such as Timing Advance, for use in communication with an orbiting satellite-based access node (141) of a non-terrestrial network (130). The method comprises determining, at repeated occasions, a time of reception (Tk) in the UE of a reference signal which is transmitted with a predetermined period (?P) from the access node. A value of the parameter is calculated based on a position (51,52) which satisfies a spatial condition for the UE, which spatial condition is given by a propagationtime difference (?k) of the reference signal between said occasions (Tk, Tk+1).

  • Publication number: 20240048667
    Abstract: Techniques are provided for x-ray onset detection for an intraoral dental sensor. A methodology implementing the techniques according to an embodiment includes calculating a plurality of superpixel values for each of a plurality of rows of detector pixels of a sensor. Each of the superpixel values is based on a sum of pixel values of a set of pixels associated with the superpixel value, the set of pixels selected from the detection row of a current frame of the sensor. The method also includes calculating a difference between each of the superpixel values and a corresponding stored superpixel value generated from a previous sensor frame and determining if the differences exceed a superpixel threshold value. The method further includes incrementing a hit counter in response to the determination and generating a detection signal if the hit counter exceeds a hit count threshold, otherwise proceeding to process the next detection row.

  • Patent number: 11895021
    Abstract: A first network device sends a border gateway protocol (BGP) message to a second network device. The BGP message includes Ethernet virtual private network network layer reachability information (EVPN NLRI) and first information. The first information indicates a first maximum rate at which the second network device sends traffic to the first network device based on the EVPN NLRI. When the second network device sends the traffic to the first network device based on the EVPN NLRI, a first-type rate is less than or equal to the first maximum rate. According to the method in this application, less public network bandwidth is occupied, and overheads of the network device can be reduced.
