  • Publication number: 20220196539
    Abstract: The present application discloses a nanoparticle recognition device and method based on detection of scattered light with electric dipole rotation. According to the scattering model of nanoparticles, the in situ detection of particle morphology in an optical trap is realized by the methods of particle suspension control and scattered light detection and separation. Specifically, two linearly polarized laser beams are used, wherein the first laser beam suspends nanoparticles and rotates nanoparticles by adjusting the polarization direction; the polarization direction of the second linearly polarized light is unchanged, and scattered light in a specific dipole direction is excited; the change of the polarizability of the nanoparticles is deduced by monitoring the change of the light intensity of the scattered light excited by the second laser beam at the fixed position, so that particle morphology recognition is realized.

  • Patent number: 10652156
    Abstract: When a Real-Time Transport Protocol (RTP) packet receiving manner of a user equipment (UE) is switched between a unicast transmission manner and a multicast transmission manner, a group communication service application server (GCS AS) obtains a time difference between a time at which the UE receives a first RTP packet before the switching and a time at which the UE receives a second RTP packet after the switching. The GCS AS calculates a delay difference, according to the time difference, of RTP packet transmissions in different transmission manners, and adjusts, according to the delay difference, timing for RTP packet transmission in the unicast transmission manner.

  • Patent number: 10448348
    Abstract: Embodiments of the present disclosure provide an RTP packet transmission method and apparatus. A GCS AS or a BM-SC provides synchronization source information of the GCS AS and synchronization source information of the BM-SC for UE, so that the UE can continuously receive RTP packets. On one hand, the GCS AS (or the BM-SC) may provide the synchronization source information of the GCS AS (or the synchronization source information of the BM-SC) for the UE by sending an RTP packet. On the other hand, the GCS AS (or the BM-SC) further provides the synchronization source information of the BM-SC (or the synchronization source information of the GCS AS) for the UE. Therefore, when being in a unicast (multicast) transmission mode, the UE can obtain both of the synchronization source information of the GCS AS and the synchronization source information of the BM-SC.
