A method of and apparatus for selective delivery of an interrupt to one of multiple processors having independent operating systems is described. The elastic links run freely around the push-rods such that front ends of the elastic links are permanently and preferably fixed to the base and rear ends are fixed under no tension in a slot of a bolt or arrow. On the other hand, the variable capacitor element includes a stationary electrode formed on a Si substrate, an anchor section formed on the Si substrate, a first electrode supported on the anchor section and positioned to face the Si substrate, a second piezoelectric film formed on the first electrode, and a second electrode formed on the second piezoelectric film. This increases an operating lifetime of the ceramic cutting tool. The concentration of the first metal in a central portion of the ion metal layer is higher than the concentration of the first metal in an end portion of the ion metal layer. This information is mapped to one or more game controller commands.
