A plurality of virtual machines (VMs) is established and maintained by virtualization software on one or more physical servers. Desktop management software operates to provide the VMs to remote users as virtualized desktops. The desktop management software includes a rule engine that can be used to automate the policies of the organization. The rule engine manages the data center by controlling virtual infrastructure operations, such as power-on, power-off, suspension, and migration operations. The rule engine uses an event-condition-action paradigm, wherein an event causes a virtual infrastructure operation, possibly contingent on a condition. The rule engine provides for time-based scheduling of events in addition to system-based operations, which are triggered by events such as user logon and user logoff. The rule engine may also include the ability to automate the process of changing the properties of the virtual machines in a timely fashion.

A cover-positioning device for a barbecue has a substantially L-shaped slot including a first end and a second end and a bolt. The cover-positioning device for a barbecue is fixed to a barbecue body. The bolt is inserted through the slot and slidable along the slot. The bolt is then fixed to a barbecue cover. When the bolt is in the first end of the slot, the barbecue body is covered. The barbecue cover can be remain opened with the bolt being in the second end of the slot.

A knockdown type ash catch tray in the shape of a round plate that can be easily mounted and dismounted on the legs of a barbecue kettle, particularly a charcoal kettle. The outer edges of the plate are downwardly folded to form a folded side provided on the circumference thereof with the same number of mounting holes as the legs of the barbecue kettle. Each mounting hole having the profile of an L-shape includes a fitting hole portion at one end thereof, a guiding hole portion at the middle thereof and a hanging hole portion at the other end thereof. These hole portions are arranged in communicating with one another. By aligning the mounting holes on the ash catch tray respectively with the studs provided at a predetermined height on the corresponding inner sides of the legs of the barbecue kettle and turning the tray in one direction, the ash catch tray can be easily engaged with the studs and supported in position on the legs of the kettle. When turning the tray in the reverse direction, the mounting holes can be released from engagement with the studs and thus dismounted from the legs of the barbecue kettle.

A three-phase vacuum interrupter switch assembly for power distribution systems comprises an outer case having at least one window, a plurality of internal disconnect switch assemblies, and a plurality of vacuum interrupter bottle switch assemblies within the case. Each vacuum interrupter bottle switch is coupled in electrical series with a corresponding internal disconnect switch assembly. Because the open/closed state of a bottle switch is not directly observable owing to its sealed interior, a direct visible indication of the state of the three-phase vacuum interrupter switch assembly is provided by a visually detectable contact rod for each internal disconnect switch that is visible through the case window. To prevent potentially serious damage caused by arcing between the contacts of the internal disconnect switch, the internal disconnect switch is prevented from opening or closing when the bottle switches are closed. The case interior is preferably free of oil and/or SF6 gas.

A ball-grid array (BGA) IC packaging frame of the invention includes a plurality of ball-grid array tin balls formed on the rear surface of a BGA package and a plurality of supporting pads formed on the surrounding of the rear surface. The designed supporting pads can efficiently prevent a non-contact soldering and a short circuit when a BGA IC is mounted on a PCB during manufacturing.
