Abstract: Wireless local area network (WLAN) device testing that includes acquiring a data flow feature value used in testing a WLAN device, generating a WLAN simulation environment based on an interference environment index feature of the WLAN, controlling a data transmitter in the WLAN simulation environment to transmit a data packet based on the data flow feature value, acquiring a reception status of the data receiver device for the data packet, and based on the reception status of the data receiver device for the data packet, testing the network performance in the simulation environment.

Abstract: This application provides a method for accessing a wireless network performed by an electronic device acting as a station (STA). The method includes: determining interference information of a target channel, the target channel being a channel currently connected between the STA and an access point (AP); determining a target network access parameter group corresponding to the interference information; disconnecting the target channel between the STA and the AP; and accessing the AP via a new channel established between the STA and the AP according to the target network access parameter group.

Abstract: A head-mounted display device assembly and an external adjustment module are provided. The head-mounted display device assembly includes a head-mounted display device and the external adjustment module. The head-mounted display device has a first lens and a second lens corresponding to both eyes, and also has a driven mechanism. The first lens and the second lens are respectively coupled to the driven mechanism. The external adjustment module is used for assembling and electrically connecting to the head-mounted display device, and includes a driving element and a transmission element. In a coupling state, the transmission element is coupled to the driving element and the driven mechanism, and the driving element drives the driven mechanism via the transmission element to adjust a distance between the first lens and the second lens. In a separation state, at least one of the driving element and the driven mechanism is separated from the transmission element.

Abstract: A BLUETOOTH reconnection method is used in a BLUETOOTH connection system that includes a first device and a second device. The method includes that the first device sends a BLUETOOTH Low Energy (BLE) advertising signal to the second device after a BLUETOOTH connection between the first device and the second device is disconnected. If the second device determines that the received BLE advertising signal is a first BLE advertising signal, the second device does not page the first device, and waits to receive a page packet sent by the first device. If the second device determines that the received BLE advertising signal is a second BLE advertising signal, the second device actively pages the first device, and the first device waits to receive a page packet sent by the second device.

Abstract: An apparatus and method for processing semiconductor substrates provides a substrate stage being a rotatable disc with a solid surface and a terraced edge with upper, intermediate and lower portions of increasing diameter. A hollow edge ring rests on the intermediate edge portion and a substrate disposed on the rotatable disc is lifted and transported by robot blades positioned beneath the edge ring and which lift the edge ring which holds the substrate around its edges. The rotatable disc and edge ring find application in MOCVD and other semiconductor manufacturing tools.
