  • Publication number: 20230336207
    Abstract: The present disclosure provides a method (400) for facilitating Antenna Calibration, AC. The method (400) includes: identifying (410) a leakage signal from a signal received at an AC signal receiver and resulted from a reference signal originated from an AC signal transmitter passing through an AC signal path from the AC signal transmitter to the AC signal receiver; and cancelling (420) an influence of the leakage signal on an AC process.

  • Patent number: 10186793
    Abstract: A light cap electrical connection structure includes a driving board, a light cap body and a first electrode pin. The light cap body is a shell structure. One end of the first electrode pin is fixed on the light cap body and further including a socket. The socket is set on the driving board and includes a connection base and a first electrode. The first electrode is set on the connecting base and has a fixed end and a connecting end. The connecting end of the first electrode is an elastic structure. The other end of the first electrode pin is inserted into the light cap body and becomes an electrical connection in elastic contact with the connecting end of the first electrode. The light cap electrical connection structure has advantages of a simple structure and being easy to automate.
