There is provided a method for controlling an image pickup apparatus in an image delivery system delivering an image acquired from the image pickup apparatus to at least one of multiple external devices, the image pickup apparatus being remotely controllable by the multiple external devices. The display of the time sequential signal is paused whenever a displayed hyperlink is selected. The method can further include elevating a temperature of the volume of material while the volume of material is applied to the microfeature workpiece to alloy the first metallic constituent and a second metallic constituent so that the second metallic constituent is distributed generally throughout the volume of material. The amplitude envelope and frequency or period of the waveform is specific to the electrical and mechanical characteristics of the speaker.
