Abstract: An air mouse mode implementation method includes establishing, by an electronic device, a communication connection to a stylus through BLUETOOTH, sending, by the electronic device, notification information to the stylus through the communication connection when detecting a screen casting event of the electronic device, where the notification information instructs to enter an air mouse mode, receiving, by the electronic device, a determining instruction from the stylus through the communication connection, entering, by the electronic device, the air mouse mode based on the determining instruction, and modifying, from an arrow icon to a dot icon and by the electronic device, an indication icon corresponding to the stylus.

Abstract: A Bluetooth connection method and a related apparatus are disclosed, and relate to the field of short-range wireless communications technologies. A first electronic device establishes a BLE connection to a second electronic device, and exchanges data with the second electronic device based on a first connection interval. The first electronic device further establishes a BR/EDR connection to a third electronic device. When device class information of the second electronic device is the same as device class information prestored in a memory, the first electronic device exchanges data with the second electronic device based on a second connection interval. The second connection interval is greater than the first connection interval. In this way, a throughput speed of exchanging data by the third electronic device can be increased.

Abstract: An air mouse mode implementation method and a related device are provided. The method includes: An electronic device establishes a communication connection to a stylus through Bluetooth (S301); sends notification information to the stylus through the communication connection when detecting a screen casting event of the electronic device, where the notification information is used to indicate whether the stylus is to enter an air mouse mode (S302); receives a determining instruction sent by the stylus through the communication connection (S303); and enters the air mouse mode based on the determining instruction, and modifies, from an arrow icon to a dot icon, an indication icon corresponding to the stylus (S304). According to this method, operation convenience can be improved.

Abstract: A fully automatic ultrasonic scanner and a scan detection method is provided. The fully automatic ultrasonic scanner comprises: an ultrasonic probe (4); a driving system (5) for driving the ultrasonic probe (4) to move; and a flexible structure on which the ultrasonic probe (4) is mounted, wherein the flexible structure enables the ultrasonic probe (4) to be always along a curve of a skin surface and keep perpendicular to the skin surface during scanning. The flexible structure of the fully automatic ultrasonic scanner has self-adaptive effect, can adjust the scan trace and the probe angle in real time according to different curves of the human body, and ensure that the ultrasonic probe (4) scans against the skin surface and keeps perpendicular to the skin surface, which improves the quality of the scanned images, so as to enhance the detection rate and accuracy rate of early screening, and reduces the probability of missed diagnosis.
