Abstract: A semiconductor wafer includes semiconductor dies and laser grooves formed in the scribe lines along the long edges of the semiconductor dies. A laser groove extends between the long edges of two adjacent semiconductor dies to encompass the corners of the two adjacent semiconductor dies. This prevents die cracking, for example during backgrind of the wafer. Moreover, the absence of laser grooves along the short edges of the semiconductor dies prevents die cracking, for example along short edges of dies overhanging empty space that are stressed during portions of the packaging process.

Abstract: A debugging method for a Universal Serial Bus (USB) device includes: receiving input information of a terminal through a Human Interface Device (HID) device; when report ID of the input information is a serial port ID, transmitting the input information to a buffer of a virtual serial port Teletype (TTY) device; and extracting the input information of the terminal from the buffer of the virtual serial port TTY device, executing a shell command on the input information, and returning execution result to the terminal through an original path. The method uses a USB interface to implement a HID device, thereby realizing drive-free execution. In addition, use of the endpoint of the HID device can save endpoints needed for additional debugging and driving.

Abstract: The present application discloses a media interaction method in a Digital Enhanced Cordless Telecommunications (DECT) network cluster. Communication with a DECT host is established through a DECT network cluster constructed in advance, to obtain first account information allocated by the DECT host, and information of a first call request to call a second account is sent to the DECT host, so as to make a call to the second account in a first communication manner. If no Real-time Transport Protocol (RTP) from the second account is received, information of a second call request to call the second account is sent to the DECT host, so as to make a call to the second account in a second communication manner. Embodiments of the present disclosure can solve the technical problem of a communication failure and reduce a waiting time for communication, thereby achieving optimal Voice over Internet Protocol (VOIP) call experience.

Abstract: The present disclosure relates to the field of communications technologies, and specifically, to a video conference terminal and a video conference system. The video conference terminal is provided with a content receiving module (101), an audio and video processing module (102), and a display module (103). To be specific, the video conference terminal (100) has a video conference function, so that the video conference terminal can serve as both an audio conference terminal and a video conference terminal, thereby enriching functions of the video conference terminal. Compared with a conventional conference terminal, the video conference terminal provided in embodiments of the present disclosure has easy deployment, low costs and high utilization as it can serve as a video conference terminal.

Abstract: Disclosed herein is a network encryption method for realizing encryption of a local area network at the bottom layer driver of a network card of an embedded device. By using such method, an encryption protocol is performed on the network card driver, thereby achieving encryption and decryption of all network data in the network card driver within the local area network, and achieving encryption of all data above network linking layer, so as to achieve unified encryption of all data in the local area network, resulting in enhanced safety of transmission of network data. Moreover, since encryption of the network data is performed in the network driver, developers do not need to focus on encryption situation.

Abstract: The present disclosure discloses a universal debugging method for a USB device and the USB device. In one embodiment, receiving input information of a terminal through a HID device; when report ID of the input information is a serial port ID, transmitting the input information to a buffer of a virtual serial port TTY device; extracting the input information of the terminal from the buffer of the virtual serial port TTY device, executing a shell command on the input information, and returning execution result to the terminal through the original path. Based on the teachings of this embodiment, using USB interface to implement a HID device can realize drive-free execution, and at the same time, by using the endpoint of the HID device, endpoints needed for additional debugging and driving can be saved.
