Abstract: A method for detecting the state of the proximity sensor, applied to a terminal including the proximity sensor and an antenna, includes: sending a predetermined instruction to the proximity sensor; determining whether the proximity sensor is abnormal based on a feedback result of the proximity sensor to the predetermined instruction; and maintaining the antenna transmitting power at a low power if the proximity sensor is abnormal. Through the feedback of the proximity sensor to the request to obtain the capacitance value, it is determined whether the proximity sensor can work normally, and in a case that the proximity sensor cannot work normally, the antenna transmitting power is reduced to avoid the continuous high antenna transmitting power due to the inability of the proximity sensor to work normally, which reduces the radiation to the human body.

The method can include: encoding a data file to be sent to obtain an encoded file; and modulating the encoded file and sending it in the form of radar wave via the radar wave sensor. A wide range of data transmission can be performed in the form of radar wave, by providing the radar wave sensor in the mobile terminal, thereby enabling the data transmission more conveniently without network environment and complicated steps. One-to-many data transmission can be performed efficiently and conveniently in public multi-user scenarios.

Abstract: The present disclosure provides a control method and device for a home device and a storage medium. The control method for the home device can include monitoring an action of a user through a radar wave emitted from the radar wave sensor, and controlling the home device to perform a function corresponding to the action of the user in response to monitoring that the action of the user matches a preset action.

Abstract: The present disclosure relates to a brightness adjustment method and device, and a storage medium. The method can include detecting a brightness of an environment where a mobile terminal is located to acquire a brightness value. When a decrease of the brightness value acquired at a present moment relative to the brightness value acquired at a previous moment reaches a first preset value, a radar wave is transmitted, and an echo of the radar wave is detected. The method determines whether there is an occlusion causing the decrease of the acquired brightness value according to a transmitting parameter of the radar wave and an echo parameter of the echo. When there is no occlusion, display brightness of the mobile terminal is adjusted according to the brightness value acquired at the present moment. When the occlusion is present, the display brightness of the mobile terminal at the present moment is maintained.

Abstract: Various methods and systems are provided for an integrated arm of an imaging device. In one example, an imaging system may comprise: a base unit; a C-arm coupled to the base unit and including an x-ray source and detector positioned on opposite ends of a C-shaped portion of the C-arm; and a display monitor attached to the C-arm via an integrated arm, wherein the display monitor is movable between a first position on a first side of the C-arm, to a second position on a second side of the C-arm by traveling over a top of an upper half of the C-shaped portion. In this way, the integrated arm may provide a simplified means of orienting the display monitor while promoting better performance of the imaging system.
