Abstract: A fuel cell power controller tracks load current and fuel cell output voltage, and alerts on excessive fuel cell ramp rate, so another power source can supplement the fuel cell and/or the load can be reduced. A power engineering process makes efficient use of available fuel cell power by ramping up power flow rapidly when power is available, while respecting the ramp rate and other power limitations of the fuel cell and safety limitations of the load. Power flow decreases after an alert indicating an electrical output limitation of the fuel cell. Permitted power flow increases in response to a power demand increase (actual or requested) from the load in the absence of the alert. Power flow may increase or decrease in a fixed amount, a proportional amount, or per a sequence. A power controller relay may trip open on a low fuel cell output voltage or high load current.

Abstract: Embodiments of recovering data in computing devices and associated methods of operations are disclosed therein. In one embodiment, a method includes receiving a failure notification indicating that a core of a main processor is experiencing a catastrophic failure causing the core unable to execute instructions. In response, a flush command can be issued to an uncore of the processor via a debug port instructing the uncore to copy any data currently residing in a processor cache of the main processor to a volatile memory. The method further includes issuing a self-refresh command causing the volatile memory to enter a self-refresh mode in which the data copied from the processor cache is maintained and unmodifiable by the main processor during a reset of the main processor.

Abstract: Technologies are described which permit kernel updates or firmware fixes, and include re-initialization of kernel data structures, without losing user context information that has been created by services, virtual machines, or user applications. Tailored code in a server or other computing system sets a kernel soft reset (KSR) indicator and saves the user context to non-volatile storage. When a KSR is underway, boot code skips the power on self-test and similar initializations (thereby reducing downtime), loads a kernel image, initializes kernel data structures, restores the user context, and passes control to the initialized kernel to continue computing system operation with the same user context. Device drivers may also be re-initialized. The loaded kernel may use newly fixed firmware, or may have a security patch installed, for instance. The non-volatile storage may operate at RAM speed, e.g., it may include NVDIMM memory. The kernel may be validated before receiving control.

The method further includes maintaining the accumulated number of memory blocks in the main memory below a threshold corresponding to an energy capacity of the auxiliary power source and copying all of the stored data in the memory blocks of the main memory to the persistent storage using power from only the auxiliary power source when the main power supply suffers an unexpected power failure.

Abstract: A computing device may comprise a volatile memory and a non-volatile storage device. Upon system shutdown, contents of the volatile memory may be preserved by memory transfer operations from the volatile memory to the non-volatile storage device. During memory preservation, the computing device may enter a low-power state. The low-power state may comprise suspension of power to a core of a processor while maintaining power to the processor's uncore, and disablement of interrupt signals not related to memory transfer operations. Power delivery to the core of the processor may be periodically resumed to initiate additional memory transfer operations.
