Abstract: A display substrate and a display device are provided. The display substrate includes a base substrate, at least one group of contact pads, a plurality of first light-emitting elements, a plurality of first pixel driving circuits, a plurality of connecting traces, a plurality of data lines and a plurality of leads. The display area includes a first display area and a second display area; the first light-emitting elements are located in the first display area; the first pixel driving circuits are located in the second display area; the leads are located in the first display area and the peripheral area, and connect the data lines and the at least one group of contact pads; orthographic projections of the first light-emitting elements on a substrate surface of the base substrate are at least partly overlapped with orthographic projections of the leads on the substrate surface of the base substrate.

Abstract: The present invention provides a technical solution for an easy, highly reliable and secure out-of-band management of a remote computer with low cost of facilities. The present invention comprises a webcam which is used as a lightweight video sniffer, an emulator of keyboard and mouse, a mirror of remote disk which contains software resources and writable data file, a mirrored agent which runs on the computer which will be controlled remotely and render output of captured screen shot, and an assistant device which connects to a remote console and bridges an out-of-band management for the controlled computer. In the present invention, the controlled computer can be diagnosed remotely by a keyboard or a mouse with a mirror of remote software resources when the computer suffers from various kinds of problem, even when the whole Local Area Network (LAN) where the computer resides in is isolated from the remote console.

Abstract: A method, device, and system for detecting the occurrence of a disaster event and providing a disaster warning to users is disclosed. In one embodiment, the method includes receiving a warning notification with an out-of-band (OOB) processor of a computing device. The warning notification may be received by the OOB processor while an in-band processor of the computing device is in a reduced-power state. The method also includes generating a user alert on the computing device in response to receiving the warning notification. The method may additionally include detecting the occurrence of a disaster event and transmitting data to a remote server in response to detection of the event.
