Abstract: Implementations of the present specification provide a method and an apparatus for managing a TLB cache in a virtualization platform, where the virtualization platform runs a plurality of virtual machines, each virtual machine is allocated with a unique VPID, and all virtual logical processors in the virtual machine share the VPID; and a guest process running in the virtual machine is allocated with a PCID. An identifier field of a TLB entry in the TLB cache includes a VPID and a PCID.

Abstract: A kit for assisting in the location of holes to be drilled in a door of a thickness between 1?? to 1¾? for the installation of a conventional lock set at a backset of either 2?? or 2¾? with no additional hardware and without damaging the door. A first guide plate defines a first hole saw guide. A second guide plate is attachable to the first guide plate in one of two orientations and defines a second hole saw guide. At least one clamping member is carried by the second guide plate and extends substantially parallel to the first guide plate. Each of the first guide plate and the clamping member define opposing biasing members such that when mounted on a door, the door is centered within the kit.

Abstract: The present invention provides a method for generating hydroxyl radicals and removing organic pollutants in water by utilizing an organic membrane. The inventive method generates hydroxyl radicals by adopting a nitrocellulose membrane as a photocatalytic material, placing the nitrocellulose membrane in water, illuminating with the sun or a sunlamp having a wavelength above 280 nm as a light source, and causing the nitrocellulose membrane to undergo a photochemical reaction at the membrane surface, and the generation rate of hydroxyl radicals can be achieved by adjusting the surface area of the membrane and a light intensity. The generated hydroxyl radicals can remove phenol, bisphenol A, thiamphenicol and other typical organic pollutants in water very well.

Abstract: A glue thickness inspection system automates a thickness measurement functionality for determining the thickness of both non-transparent and transparent materials including, but not limited to, glue, gel, solder and epoxy. The glue thickness inspection system includes a laser detector, a movable platform for positioning a unit under test, and a controller for controlling movement of the platform, angle of the laser detector, and calculation of the transparent material thickness. The laser detector includes a laser for emitting a laser light onto the unit under test and a sensor for receiving corresponding reflected light. The sensed data is used by the controller to determine the transparent material thickness.
