Abstract: A gas spring-powered fastener driver includes a cylinder, a moveable piston positioned within the cylinder, a driver blade attached to the piston and movable therewith between a ready position and a driven position, a lifter to move the driver blade from the driven position to the ready position, and a transmission including an output shaft operatively coupled to the lifter to provide torque to the lifter. The fastener driver also includes an input to provide torque to the transmission and a clutch positioned downstream of the input and operably coupled to the output shaft to limit an amount of torque transferred to the output shaft and the lifter. In response to an application of a reaction torque to the output shaft above a predetermined threshold, torque from the input is diverted from the output shaft via the clutch.

Abstract: Embodiments described herein identify hot pages associated with a virtual machine that is selected for hibernation or for migration from one computing system to another. For example, before migrating a virtual machine, a hypervisor monitors the entries in a page table (e.g., a virtual translation table) to see what data pages have corresponding entries in the page table. If a data page has a corresponding entry in the page table, the hypervisor may designate that page as hot. A source computing system may transmit the hot data pages to a target computing system which loads the pages into memory. After loading the hot pages into memory, the source computing system may cease executing the virtual machine while the target computing system begins to execute the virtual machine. The rest of the data pages associated with the virtual machine may be transmitted to the target computing system subsequently.

If a data page has a corresponding entry in the page table, the hypervisor may designate that page as hot. In one embodiment, the hypervisor may update a page map that lists the data pages associated with the virtual machine and whether those data pages are designated as hot. The page map may then be stored during the hibernation process. Before the hibernated virtual machine is resumed, the hypervisor may use the page map to load the hot pages into memory and begin executing the virtual machine.

Abstract: Exemplary methods, systems, and products are described for executing an overall quantity of data processing within an overall processing period that include executing repeatedly through a series of iterations a portion of the overall quantity of data processing that can be completed in a set processing period, wherein each iteration includes the set processing period and a variable delay period and calculating the variable delay period for an iteration in dependence upon the set processing period, a portion of the overall quantity of data processing performed during the set processing period of the iteration, the overall quantity of data processing, and the overall processing period.

Abstract: Methods, systems, and media for timed power-on in a logically partitioned environment are disclosed. Embodiments may disclose determining a time period based upon a time to launch a partition and a time of day associated with the next partition to launch. After determining the time period, a timer is set to boot the system based upon the time period. More specifically, embodiments allow the timed power-on (TPO) and time of day (TOD) of logical partitions to be modified by clients independently of other partitions by determining the system TPO based upon TPOs and TODs of logical partitions as well as the TOD of the system. Some embodiments include initiating a transaction like an interrupt in response to a change in a TPO or TOD of logical partition or the system. Several of such embodiments incorporate adjusting or re-calculating the system TPO in response to the transaction.
