A method is proposed for analyzing an interlaced video signal including a first sequence of fields. On the basis of the information transmitted from the user unit and current time information obtained from a time keeping unit of the service center, the service center similarly creates a one-time password and an operation permission command and transmits them to the user unit. The realistic images, optionally provided to bona fide design professionals for free, promote the sale to the client of goods which are normally obtained through the graphics service provider, profiting both the service provider and the design professional. A translational air bearing laterally positions the actuator assembly within the multi-disc servo-track writer for servo-track recording. The fire wall 16 assembly withstood the fire endurance test without passage of flame and gases hot enough to ignite cotton waste during a four-hour fire exposure. An encapsulant is deposited over the semiconductor die or component and around the conductive pillar.
