  • Publication number: 20210126804
    Abstract: A power source device coupled to a power device includes an output port and a controller. When the output port is coupled to a connection cable, the controller is activated to generate a handshake signal, so as to communicate with the power device. When it is determined that the power device is able to be powered according to the handshake signal, the controller controls the power supply device to power the power device through the connection cable. When the connection cable is not coupled to the output port, the controller is deactivated and thus the handshake signal is not generated.

  • Patent number: 10990534
    Abstract: Techniques and mechanisms for capturing an image of processor state at one node of multiple nodes of a multi-processor platform, where the processor state includes some version of data which the node retrieved from another node of the platform. In an embodiment, a disruption of power is detected when a processor of a first node has a cached version of data which was retrieved from a second node. In response to detection of the disruption, the data is saved to a system memory of the first node as part of an image of the processor's state. The image further comprises address information, corresponding to the data, which indicates a memory location at the second node. In another embodiment, processor state is restored during a boot-up of the node, wherein the state includes the captured version of data which was previously retrieved from the second node.
