Retractable banner stands each comprises a base including a housing containing an extendable and retractable banner, the housing having a slot through which the banner is extended and retracted. The processes involve providing a tobacco suspension comprising finely ground tobacco material, and subjecting the tobacco suspension to heat treatment in an enclosed, pressure controlled, and generally inert environment at a temperature of at least 140 C. The cached timing-related information for the source driver can be reused when sizing a different sequential cell. In various embodiments, the teeth can be positioned between first and second surfaces of the end effector lock member to reduce the possibility that the teeth can impinge on soft tissue surrounding the lock member. A timing generator converts the multiple bit digital representation of the timing signal to a logic signal. The method determines if an application is compatible with an operating system, and if the application is determined to be incompatible, a debugger is loaded that runs the incompatible application.
