Abstract: This disclosure discloses signal configuration methods and apparatuses. In an implementation, a method comprises: generating at least two reference signals of a same type corresponding to at least two antenna ports indicated to a terminal device, wherein the at least two reference signals comprise a first reference signal and a second reference signal, wherein a first sequence of the first reference signal is obtained based on a first initialization factor determined based on an index of a first code division multiplexing (CDM) group, and wherein a second sequence of the second reference signal different from the first sequence is obtained based on a second initialization factor determined based on an index of a second CDM group; and transmitting the at least two reference signals.

Abstract: A circuit board detection method includes obtaining an input circuit board image, performing a detection on designated components of a circuit board in the circuit board image according to a preset detection method, determining whether a designated component in the circuit board image that fails the detection is allowed to shift within a preset angle range, and determining that the circuit board passes the detection when the designated component that fails the detection is allowed to shift within the preset angle range. The designated components include one or both of silkscreened components and non-silkscreened components.

Abstract: A card storing case includes a left plate and a right plate arranged opposite to one another. An inner side of the left plate and an inner side of the right plate are respectively provided with a plurality of guide grooves. The card storing case further includes a card bracket slidably arranged in the guide groove. When a card is transferred into the card bracket, the card bracket slides along the guide groove, such that the card is moved and stored in the guide groove. A card bracket and a guide groove are arranged in the card storing case, such that a card is moved and stored in the guide groove via the card bracket, which not only shortens a transfer path of the card in a process of storing or withdrawing the card, but also reduces operation time in storing or withdrawing the card.

Abstract: A positioning apparatus includes a sensor assembly, a moving member, and a detecting plate. The sensor assembly includes a sensor positioning and detecting assembly and a sensor location recognition assembly. The sensor assembly is mounted on the moving member, and the moving member drives the sensor assembly to move on the detecting plate. The sensor assembly moves on the detecting plate, the sensor location recognition assembly recognizes that the sensor assembly reaches a designated location, and the sensor assembly is positioned by the sensor positioning and detecting assembly. The positioning apparatus and the card issuing machine provided by the application avoid the phenomena of step lost and speed reduced, and the location of the sensor assembly can be monitored in real time through the detecting plate.

Abstract: An embodiment of the present invention provides a card issuing device, which includes a card storing mechanism, a transport mechanism, and a base. The transport mechanism is arranged in the base. The card storing mechanism is arranged above the transport mechanism. The card storing mechanism comprises a pressing block and a buckle. The transport mechanism comprises a guide rail and a card hook. The transport mechanism transports a card by cooperating of the guide rail and the card hook. The card storing mechanism fixes the card via the pressing block and the buckle. The base is configured to fix the card storing mechanism and the transport mechanism. According to the present invention, a card issuing box and a card receiving box are integrated into one body to reduce structural complexity, reduce costs, and improve space utilization rate.
