摘要:
An input-output memory management unit (IOMMU) and method for tracking memory pages during virtual-machine migration are generally described herein. The IOMMU includes an IOMMU manager to service address translation requests associated with memory pages received from a plurality of I/O devices, and a translation request filter to identify translations previously requested from a translation manager. The IOMMU also includes a device context table to identify whether virtual-machine migration is enabled for memory pages associated with virtual addresses identified in received address translation requests. Based on information in the device context table, the IOMMU manager may send a virtual page identifier to the translation manager identifying a virtual page when virtual-machine migration is enabled to indicate that the virtual page has been accessed. The IOMMU manager refrains from sending the virtual page identifier to the translation manager when the virtual page is listed in the translation request filter.

An instrument for preparing a surface of a vertebra, such as a vertebral endplate, for receipt of a spinal disc implant. The instrument includes a working tool with implements on one or more surfaces of the working tool that act on the vertebral surface. The instrument includes a rotary-to-linear translation system to cause the working tool to move; for example, from side-to-side, top-to-bottom, or along a path that includes side-to-side and top-to-bottom aspects. The rotary-to-linear translation system may include a drive shaft having a cam pin at a distal end, and a cam follower slot at an anterior end of the working tool.

A mattress carrier includes a bag made of a sheet of plastic film material. The bag is sized to receive a mattress and has an opening for placing the mattress into the bag. An extension on at least one side of the bag has a plurality of layers of the plastic film material formed with a gusset. Handles are formed as openings in the extension. The bag has a seal for bonding the layers of film together along at least a portion of the length of the side having the extension. The seal is formed along a line between an outer edge of the gusset and an inner edge of the gusset.

An electronic device (110, 210) includes a housing (120) encasing a component (112, 114). The housing (120) includes a region (300, 600, 800, 1000) contiguous to the component (112, 114), the region (300, 600, 800, 1000) configured to selectively switch between a metallic appearance to transparent to reveal the component (112, 114) through the region (300, 600, 800, 1000) when transparent. Metal surfaces, metal particles, or shiny particles that are incorporated into device structures may be actuated. The grain sizes of the particles can be adjusted to achieve the desired reflections. In addition, individual shutters (318, 618, 818, 1018) can be fabricated with a distribution of predisposed orientations to enhance the reflectivity.

摘要:
An apparatus (10) for, and method of, placing a plurality of spacers (12) between a parallel opposed anode and cathode (20) of an emissive display includes temporarily securing, by applying a vacuum for example, a first side of one of the anode or cathode to a base (14) having a plurality of electromagnets (16) positioned therein. The electromagnets (16) attract a first side of each of the plurality of spacers (12), thereby positioning each of the spacers (12) in a desired location on a second side of the one of the anode or cathode (20). The spacers (12) may be provided from a shuffling tray (40) having a plurality of openings (42), each opening (42) approximately aligned with one of the electromagnets (16) and shaped so as to present the first side to the electromagnet (16) to the one of the anode or cathode (20).

An apparatus and method for improving print quality in a rotary offset press includes a variable speed servo motor for selectively applying a driving or braking action to a form roller in contact with a plate cylinder. The servo motor may be directly coupled to the form roller by a belt drive independent of the press drive and controlled to maintain a selected surface speed differential between the plate cylinder and the form roller during printing.
