Abstract: A first optical path pointing apparatus includes a first optical transceiver, a first position sensitive detector, and a first adjuster. The first optical transceiver is configured to transmit a first beacon light to a second optical path pointing apparatus and configured to receive the first beacon light reflected by a second prism in the second optical path pointing apparatus. The first position sensitive detector is configured to determine a first alignment angle of the first optical path pointing apparatus based on first information of a position at which the first beacon light reflected by the second prism reaches the first position sensitive detector and send the first alignment angle to the first adjuster. The first adjuster is configured to adjust the first alignment angle thereby generating an adjusted first alignment angle that satisfies a first pointing precision threshold.

Abstract: A light sensor status control method, includes: a processor (110) determines a display time period and a non-light-emitting time period in a image refresh cycle (501); and the processor (110) controls an optical transmitter of a light sensor (180G) to transmit an optical signal when pixels in a display area that is of an OLED display screen (194) and that corresponds to the light sensor do not emit light in the image refresh cycle, and the processor (110) controls the optical transmitter not to transmit an optical signal when the pixels in the display area that is of the OLED display screen (194) and that corresponds to the light sensor (180G) emits light (502). Therefore, a problem that the screen blinks because the light sensor emits infrared light is alleviated, and a display effect of the screen is improved.

Abstract: A foldable apparatus is provided. The foldable apparatus includes a first foldable part, a middle bending part, and a second foldable part that are connected in sequence. The first foldable part and the second foldable part can rotate relative to each other based on the middle bending part. A first wireless communication chip is disposed in the first foldable part. A second wireless communication chip is disposed in the second foldable part. In the foldable apparatus, wireless communication is used to replace conventional physical wiring for internal signal transmission. The loss of a communication carrier is reduced through wireless communication. This ensures that stable transmission performance between the first foldable part and the second foldable part.

Abstract: Embodiments of the present invention provide a fault diagnosis method and apparatus. A service in the fault diagnosis method relates to at least one user, and the fault diagnosis method includes: determining whether a terminal of each user allows performing fault diagnosis for the service; and performing fault diagnosis for the service if the terminal of each user allows performing fault diagnosis for the service. In the embodiments of the present invention, fault diagnosis for the user related service cannot be performed unless allowed by a user terminal or allowed by both the user terminal and a system side. Thereby, it is ensured that fault diagnosis is performed in a secure environment, which better complies with security laws and regulations.
