Abstract: A method for preserving volatile memory across a computer system disruption includes identifying a set of volatile memory. The set of volatile memory represents a portion of data in volatile memory to preserve during a system disruption. The method includes receiving a system event. The system event indicates that a computer system disruption will occur and that the set of volatile memory is to be written to a stable storage device. The method includes writing the set of volatile memory to the stable storage device to create a stored data set.

Abstract: Example implementations relate to server node shutdown. For example, a server node shutdown can include detecting a secondary power supply integrated into a server node, receiving a primary power supply interruption signal from the secondary power supply, and initiating a sequenced shutdown of the server node in response to receiving the signal using the secondary power supply.

Abstract: Example implementations relate to load discovery. For example, a load discovery system can include a shared backup power supply controlled by a backup power control module, and a node coupled to the shared backup power supply, wherein the node supports a plurality of loads, and the shared backup power supply powers the plurality of loads when the node is powered off, and a baseboard management control (BMC) unit coupled to the node, the BMC unit to discover the plurality of loads.

Abstract: A non-invasive motion and respiration monitor receives impulses from a subject's movement, heartbeat, and respiration. The raw signal is biased and digitized, and a signal processor applies a Fast Fourier Transform to the signal. The transformed signal is filtered to isolate the component representing heart rate from the component representing respiration. An Inverse Fast Fourier Transform is then applied to the component signals, which are sent to a processor. The processor is programmed to detect irregularities in the respiration and heart rate. If severe irregularities or complete cessation is detected in either signal, a mechanical stimulator is actuated to try to stimulate the subject, and an alarm is sounded to alert a caregiver such as a parent or nurse.
