Abstract: A touch frame assembly and an interactive white board are provided. The touch frame assembly includes: an infrared touch frame, including a frame body and a PCB assembly arranged in the frame body; a glass cover plate, located on an inner side of the PCB assembly; a fixing structure configured to fix the glass cover plate to the infrared touch frame, wherein the glass cover plate controls an inward concave of the glass cover plate through a curvature of the frame and/or the fixing structure.

Abstract: The present disclosure disclosed a method for projecting a device screen, apparatus, device, and storage medium. The method includes: when a screen projection instruction is received, determining the number of device screens to be projected; based on at least one of the principle of equal distribution and/or a principle that a first display screen is projected first, and the previously-acquired number of projected device screens on each display screen and the number of device screens to be projected, determining a target display screen of each device screen to be projected; and projecting and displaying each device screen to be projected on a corresponding target display screen.

Abstract: The present disclosure provides a camera device, including a housing assembly, and a camera module. The housing assembly includes a front housing, a rear housing, a housing body, and a first installation pin. The housing body is equipped with a first positioning hole. The first installation pin passes through the first positioning hole, and two opposite ends of the first installation pin are fixed to the front housing and the rear housing respectively to fix and connect the front housing and the rear housing. The housing body is tightly clamped by and fixed between the front housing and the rear housing. An installation space is surrounded by the front housing, housing body, and rear housing. The camera module is located in the installation space and fixed to the housing assembly. The camera device has a housing body clamped tightly by and fixed between the front housing and the rear housing.

Abstract: Embodiments of the present disclosure discloses a method and a device for connecting apparatuses, apparatuses and storage medium, which relates to the field of communication. The method includes: determining whether the first apparatus stores an identifier of a target-type apparatus; when the first apparatus stores the identifier of the target-type apparatus, transmitting triggering information to a second apparatus, wherein the triggering information is used to trigger the second apparatus to transmit a connection request, a type associated with the second apparatus is the target type, and the second apparatus is connected with the first apparatus through a wired input line; receiving the connection request transmitted by the second apparatus; and establishing a wireless connection with the second apparatus based on the connection request. Therefore, the embodiments of the present disclosure can automatically connect apparatuses and improve an efficiency of connecting apparatuses.

Abstract: This application provides a data transmission method and a data transmission device. The data transmission device is provided with a microcontroller, a power supply, and a vibration sensor. When the vibration sensor detects that the user moves the data transmission device, the microcontroller controls the power supply to supply power to the data transmission module, so that the data transmission module starts to activate before the data transmission device is connected to the electronic device, thereby improving the response speed and work efficiency of the data transmission device. Meanwhile, the power supply does not need to supply power to the data transmission module constantly, which reduces the capacity and volume of the power supply.
