Disclosed is a wireless headset role switching method, relating to the technical field of portable listening devices, wherein a main wireless headset is a headset currently establishing a connection with a terminal, and a slave wireless headset is a headset not currently establishing a connection with the terminal. The method includes: when receiving an in-place instruction, a main wireless headset sending connection information of the main wireless headset and a terminal to a slave wireless headset, so that the slave wireless headset initiates a connection request to the terminal according to the connection information and establishes a connection with the terminal, thereby completing wireless headset role switching. Also disclosed are a wireless headset, a wireless connection device role switching method, a TWS headset and a computer-readable storage medium, having those beneficial effects.

A method for adjusting an openable angle of display screens, and a multi-screen terminal. The method includes: detecting, by a multi-screen terminal, an intensity of ambient light and a corresponding light incident angle of each display screen, and obtaining a currently used display screen as well as a viewpoint angle between the currently used display screen and a user; judging, by the multi-screen terminal, whether the intensity of ambient light corresponding to a light incident angle having the smallest difference with the viewpoint angle is greater than a preset value, and adjusting, under the condition that the viewpoint angle is greater than the preset value, an openable angle between the display screens until the multi-screen terminal judges that the intensity of ambient light corresponding to the light incident angle that is closest to the current viewpoint angle is less than or equal to the preset value.

A photographing method, device and system, and a non-transitory computer-readable storage medium are disclosed. The photographing method may include: sending a first image or a feature thereof to a cloud server, where the first image is acquired through a built-in camera of the mobile terminal (100); and receiving a third image from a cloud server, which is determined by the cloud server, in response to meeting a first preset condition based on a second image captured by a camera arranged on-site, and performing detail enhancement on the first image according to the third image which meets the first preset condition, where the first preset condition includes: a capture time interval between the third image and the first image being less than or equal to a preset time interval, and the third image being able to be utilized to enhance the first image partly or entirely (101).

Monitoring and locating tracked objects using audio/video (A/V) recording and communication devices in accordance with various embodiments of the present disclosure are provided. In one embodiment, a method for monitoring an object using a smart-home hub device in network communication with A/V recording and communication devices is provided, the method comprising: associating a tag having tag data compatible for use in a low-power wide-area network (LPWAN) with at least one tracked object to be located when missing; activating the smart-home hub device to monitor the at least one tracked object on a premises by listening for the tag data transmitted by the tag; determining when the at least one tracked object has been removed from the premises using the tag data; and transmitting to a first client device, an alert upon a determination that the at least one tracked object has been removed from the premises.

An adsorbable electrical coupling device having charging and data backup functions is provided. An adsorbable coupling component is detachably coupled to a coupling component of an electronic device, such that the adsorbable electrical coupling device is adsorbed on and electrically coupled to the electronic device. When the adsorbable electrical coupling device is electrically coupled to the electronic device, the electronic device receives power from a power supply device of the adsorbable electrical coupling device. A data storage component may backup data of the electronic device or provide data stored in the data storage component to the electronic device. When one or both of power and data are transmitted between the adsorbable electrical coupling device and the electronic device, a user is allowed to manipulate the electronic device to execute other programs.

A voice information processing apparatus sequentially converts an utterance of a user into text during a voice reception period that is a period in which an uttered voice to be converted into text is received from a user, and in a case where it can be regarded that the utterance of the user has been interrupted, the voice information processing apparatus automatically causes utterance content already uttered by the user to be output by a voice during the voice reception period. As a result, the voice information processing apparatus can cause the user to recognize a content of a sentence that has been uttered by the user so far and converted into text, when it can be regarded that the utterance of the user has been interrupted.
