A method for varying the resonance frequency of a resonator beam is disclosed. The irrigation control software provides a graphical user interface to create a more efficient irrigation scheduling control interface. The controller is configured to control the at least one vibrator motor to change orientation of the apparatus during a portion of the drop motion. The end of the neck and the flare of the stem are welded to each other such that a glass portion of the flare surrounds a glass portion of the end of the neck from outside. In various embodiments, the surgical staples can include crowns having arcuate andor cylindrical features which can cooperate with arcuate andor cylindrical features of the staple cavities in order to reduce unwanted relative movement, or rotation, between the staples and the staple cavities. The continuous polysilicon layer, preferably no thicker than 50, serves a sacrificial purpose and prevents interaction between any fluorine that is released during the refractory material deposition step from interacting with the underlying silicide.
