摘要:
In a method for managing power of host computers using a control computer, the method generates a power management command, groups virtual machines installed in the host computers at a first time if the power management command is a first type, to obtain a first group of the virtual machines. The method further relocates the virtual machines in the host computers based on the first group of the virtual machines, and closes idle host computers. Closed host computers are powered on if the power management command is the second type, all the virtual machines at a second time are grouped, to obtain a second group of the virtual machines. The virtual machines are relocated into each host computer based on the second group of the virtual machines.

A low noise amplifier with back-to-back connected diodes and a back-to-back connected diode with high impedance thereof are provided. The low noise amplifier includes a first operational amplifier (OP) and at least two first back-to-back connected diodes. The back-to-back connected diode with high impedance is formed from at least one MOS FET operated within a cut-off region. The first back-to-back connected diodes are connected electrically between the first input end and the first output end, and between the second input end and the second output end, of the first OP respectively. By the implementation of the present invention, the low noise amplifier is not only low noise, but also with low energy consumption, high stability, low circuitry complexity, and easily controlled manufacturing process.

A method of manufacturing an interconnect. A first conductive layer is formed on the wafer. Portions of the first conductive layer are removed to form a wire in the interior region and to expose the surface of the wafer in the edge region, simultaneously. An insulating layer is formed on the wire and the wafer. An opening is formed to penetrate through the insulating layer and exposes the wire. A second conductive layer is formed on the insulating layer and fills the opening.

A suspension system has a housing with an elongated aperture that has first and second coaxial aperture portions. The second aperture portion has a dimension that diminishes along an axis. A unidirectional clutch is contained within the elongated aperture, and is provided with first and second axially aligned clutch portions. The second clutch portion has a dimension that diminishes along an axis of the first unidirectional clutch arrangement. A gripper ball is disposed in the second clutch portion and communicates with the second aperture portion of the housing. The gripper ball is urged toward the axis of the first unidirectional clutch arrangement to grip a cable. A spring resiliently urges the first unidirectional clutch arrangement toward the second aperture portion. An end cap with an aperture is affixed to the first coaxial aperture portion for forming a back stop for the spring.
