Abstract: In described embodiments, a system establishes a perimeter around an area, and mobile devices within the established perimeter communicate with a server that provides and collects personal and asset safety information. The provided information might enable users associated with the mobile devices to plan actions or take routes based on a given criteria, such as a safest route, through display on the mobile device. The collected information from the mobile device might be location, emergency event, environmental factors, sensor information and the like, which might then be communicated to users and/or administrators of the system. Location information, such as through global positioning system (GPS), might provide tracking of mobile devices and users or assets associated with each mobile device. GPS functionality associates latitude, longitude and elevation (X-Y-Z coordinate axis) data with the collected and provided information.

Abstract: An active scanner bow compensator for use with a scanner is described. The scanner includes a moveable scanning platform supported within a frame. The active scanner bow compensator supports the scanner and includes a frame of reference, sensors, and an actuator. The sensors detect out-of-plane motion of the scanning platform relative to the frame of reference, and the actuators compensate for the out-of-plane motion by adjusting the orientation of the frame relative to the frame of reference. The active scanner bow compensator may be used in atomic force microscopy applications.

Abstract: A method, system, and computer usable program product for scaling energy use in a virtualized data processing environment are provided in the illustrative embodiments. A set of PIOAs is configured such that each PIOAs in the set of PIOAs is a functional equivalent of another PIOAs in the set of PIOAs. A utilization of each PIOA in the set of PIOAs is measured. A number of PIOAs needed to service a workload is determined. A first subset of PIOAs from the set of PIOAs is powered down if the number of PIOAs needed to service the workload is smaller than a number of operational PIOAs. The I/O operations associated with the first subset of PIOAs are transferred to a second subset of PIOAs remaining operational in the set of PIOAs.

Abstract: A method for fabrication of a lens element from a lens blank shaped from a high index, high thermal property thermoplastic resin conditions the surface of the lens blank by an extended annealing process. The temperature of the lens blank is increased to a soak temperature greater than 165 degrees C. over a ramp-up period of more than 2.5 hours, increasing the temperature during the ramp-up period by no more than 2 degrees C. per minute, on average. The lens blank is maintained at the soak temperature for a soak period of at least 3 hours. The temperature of the lens blank is lowered back to room temperature during a ramp-down period at a rate no faster than 1.5 degrees C. per minute, on average. This forms a conditioned lens blank that is diamond-turned to obtain an optical quality surface.

Abstract: A method, computer program product, and distributed data processing system that allows a single physical I/O adapter, such as a PCI, PCI-X, or PCI-E adapter, to track performance and reliability statistics per virtual upstream and downstream port, thereby allowing a system and network management to be performed at finer granularity than what is possible using conventional physical port statistics, is provided. Particularly, a mechanism of managing per-virtual port performance metrics in a logically partitioned data processing system including allocating a subset of resources of a physical adapter to a virtual adapter of a plurality of virtual adapters is provided. The subset of resources includes a virtual port having an identifier assigned thereto. The identifier of the virtual port is associated with an address of a physical port. A metric table is associated with the virtual port, wherein the metric table includes metrics of operations that target the virtual port.

An event recording mechanism of the information processing system is operable to make entries regarding events in the event queue, wherein the entries are limited to a predetermined number of active entries in the event queue per each type of event per each of the system resources. In a particular embodiment, the number of entries per each type of event for each of the system resources is limited to one.

Abstract: A computer-implemented method, apparatus, and computer program product are disclosed for managing DMA write page faults using a pool of substitute pages. The computer system's platform resolves a DMA write page fault for a page that is dedicated to an I/O adapter. The I/O adapter attempts to write DMA data to the page. A determination is made that the page is unavailable for writing. The DMA data is then written to data locations in a substitute page that was selected from the pool of substitute pages. A flag is then set in a flag location for each one of the data locations. The flag locations correspond to the data locations. When a flag is set, the flag indicates that DMA write data is present in the data location that corresponds to that flag's flag location.
