Abstract: Example configuration methods and apparatus are described. In one example method, a first baseband unit (BBU) updates a first line rate, and sends a data frame to the second BBU at an updated first line rate after each update. The first BBU receives a data frame that is sent by the second BBU at an updated second line rate after each time the second BBU updates a second line rate. When the first line rate is equal to the second line rate, the first BBU sends networking relationship information of the first BBU to the second BBU at the first line rate, and receives networking relationship information of the second BBU that is sent by the second BBU at the second line rate. The first BBU establishes a bidirectional upper-layer communication channel with the second BBU based on a communication address of the second BBU allocated by the first BBU.

Abstract: A non-contact precision pneumatic injection valve includes a cylinder, a needle disposed inside the cylinder, and an adjustable stroke limiting component. The adjustable stroke limiting component includes a thread-toothed column threadedly engaging an upper end of the cylinder; a spring-limiting column disposed inside and fixedly attached to the thread-toothed column, the spring-limiting column having a first protrusion ring; a spring column axially movably disposed inside the spring-limiting column and having a second protrusion ring, a lower end of the spring column defining a stroke of the needle; and a spring. One end of the spring fixedly engages the first protrusion ring and the other end of the spring fixedly engages the second protrusion so that the spring keeps the spring column at least partially inside the spring-limiting column. The spring biases the lower end of the spring column toward the needle.

Abstract: Provided are methods, systems, and apparatus related to a gas detector (100, 402, 802) and a gas detector calibration cap (200, 300, 404, 703, 804). The gas detector calibration cap includes a cap body (202, 302), a first cap wing (204, 304), a second cap wing (206, 306), and an extended strip (216, 316) for opening the gas detector by inserting the extended strip in a groove (106, 707, 808) of the gas detector. The extended strip allows a worker to easily open the gas detector housing, thus improving the speed and reliability of servicing the gas detector while eliminating the potential additional cost on a separated tool for opening the gas detector housing.

Abstract: A charging connector support structure includes a fixing frame, a transmission mechanism, and a rotatable support arm assembly. The fixing frame is disposed on an inner side of a vehicle body ski. The rotatable support arm assembly and the transmission mechanism are disposed on the fixing frame. An input side of the transmission mechanism is connected to a charging cap covering a charging socket. An output side of the transmission mechanism is connected to the rotatable support arm assembly. The rotation of the charging cap is transmitted to the rotatable support arm assembly through the transmission mechanism to drive the rotatable support arm assembly to switch back and forth between an initial state and a support state. The rotatable support arm assembly can support the charging connector inserted into the charging socket when the rotatable support arm assembly is in the support state.

Taking the common public radio interface (CPRI) standard as an example, by carrying multiple CPRI links on limited physical links (CPRI-MUX), generally one high-speed physical link, physical bandwidth is used more efficiently and the number of interconnected interfaces and the system cost are reduced without compromising with the CPRI standard is maintained. When the bandwidth provided by the high-speed physical link is insufficient, more physical links can be adopted.
