    摘要： A method for fabricating a quartz nanoresonator which can be integrated on a substrate, along with other electronics is disclosed. In this method a quartz substrate is bonded to a base substrate. The quartz substrate is metallized so that a bias voltage is applied to the resonator, thereby causing the quartz substrate to resonate at resonant frequency greater than 100 MHz. The quartz substrate can then be used to drive other electrical elements with a frequency equal to its resonant frequency. The quartz substrate also contains tuning pads to adjust the resonant frequency of the resonator. Additionally, a method for accurately thinning a quartz substrate of the resonator is provided. The method allows the thickness of the quartz substrate to be monitored while the quartz substrate is simultaneously thinned

    摘要： A bicycle rear-wheel hub includes an inner casing disposed in the hub at one side, an outer casing disposed on the inner casing, an axle inserted through the hub and a set of flywheels disposed on the outer casing. The hub includes an inner thread and a wheel shoulder at one end, and a rubber ring set inside the wheel shoulder in front of the inner thread. The inner casing has an outer thread at one end for engaging with the inner thread of the hub. The inner casing also has a tool hole at the opposite end for inserting a tool. The outer casing has a number of elongated grooves around the outer wall surface for fastening the set of flywheels. The flywheels each has a number of inner projections formed in a center hole for engaging with the elongated grooves of the outer casing.

    摘要： Techniques for building and managing network policies for accessing resources of a datacenter are described herein. In one embodiment, events are captured within a network element pertaining to certain activities of accessing certain resources of a datacenter, wherein the network element operates as an application service gateway to the datacenter. A new rule/policy is provisioned based on attributes extracted from the captured events, where the attributes includes at least one of user attribute, environment attribute, and a resource attribute. A simulation is performed on the new rule/policy under a real time network traffic condition, generating a simulation result. The new rule/policy is committed if the simulation result satisfies a predetermined condition, wherein the new rule/policy is enforced within the network element to determine whether a particular client is eligible to access a particular resource of the datacenter. Other methods and apparatuses are also described.
