Abstract: This application provides a wearing detection method for a wearable device and the wearable device. The wearable device includes a main body, a wrist strap, and a blood pressure detection component. The blood pressure detection component includes an airbag and an air pump. The method includes: detecting that a preset condition is met, and inflating the airbag; detecting a volume expansion rate of the airbag; determining a wearing detection result of the wearable device based on the volume expansion rate; and displaying a first interface, where the first interface includes the wearing detection result.

Abstract: A wearable device and an airbag preparation method. The wearable device includes a watch body, an airbag, and an airbag cover. The airbag is detachably connected to an end of the watch body, so that a coverage area of the airbag for the watch body is small, thereby reserving space for installing another module on the watch body. The airbag includes a first layer structure and a second layer structure that are superposed. The first layer structure has a first cavity, the second layer structure has a second cavity, and the first cavity communicates with the second cavity.

Abstract: Example optical devices are described. One example optical device includes a receiver. The receiver includes a photodetector, a first amplifier, a second amplifier, and a controller, where the photodetector is coupled to the first amplifier, the first amplifier is coupled to the second amplifier, and the first amplifier and the second amplifier are separately coupled to the controller. The controller is configured to control a gain of the first amplifier and a gain of the second amplifier based on a preset arrival time of an optical signal and a gain intensity corresponding to the optical signal. The photodetector is configured to receive the optical signal and convert the optical signal into a current signal. The first amplifier is configured to convert the current signal into a first voltage signal. The second amplifier is configured to convert the first voltage signal into a second voltage signal.
