  • Patent number: 11946981
    Abstract: A cable sequence detection method and a detection system. A base station antenna includes N ports, an RRU includes M antenna ports and one calibration port, any port i of the base station antenna corresponds to a directional coupling branch Ti, and a switch circuit Ki whose connection and disconnection are controlled by an RCU is disposed on the Ti. The method includes: the RRU sends a detection signal to the base station antenna through antenna port j; the RCU controls the switch circuit Ki to be disconnected and another switch circuit to be connected; the RRU detects whether energy Qi obtained by the Ti is greater than a threshold; and the RRU determines whether the antenna port j of the RRU is connected to the port i of the base station antenna according to whether Qi is greater than the threshold.

  • Patent number: 10830431
    Abstract: A system for deriving 100% quality steam for steam assisted gravity drainage (SAGD) injection or other applications features a once through steam generator (OTSG), a steam-water separator connected downstream of the OTSG's radiant tubes to separate steam and water from a two-phase flow received therefrom, superheater tubes installed in the convection section and connected to a steam outlet of the steam-water separator in downstream relation thereto to receive and heat dried steam therefrom to a superheated state, and a desuperheater connected downstream of the superheater tubes to receive the superheated steam therefrom and use same to vaporize blowdown water from the steam-water separator, whereby the vaporized blowdown water and the superheated steam collectively form a superheated steam output for the intended application, typically after additional separation of solid particles therefrom for optimal steam quality.

  • Patent number: 10086898
    Abstract: A mounting bracket for a stepless variable speed engine of a light motorcycle includes a frame, a shock absorber, an engine holder, a power connection plate and a hanger. The engine holder includes a beam and two engine fixing rods, and one of the engine fixing rods is fixed to an end of the beam by a bolt, and the other engine fixing rod is integrally coupled to the other end of the beam. The engine fixing rod has plural installation nodes coupled with the engine, and both ends of the shock absorber are hinged with the frame and the middle of the beam. The power connection plate is coupled to the engine fixing rod and has a shaft hole corresponsive with a shaft of the engine. The bolt is provided for fixing and adjusting the structural form of the engine fixing rod to facilitate adjusting the interval of the engine holder to provide a convenient and accurate installation.
