A fixture is for forming a fiber optic array that defines a plurality of discrete fibers extending from a spaced-apart arrangement to a consolidated arrangement wherein the fibers are layered next to each other for a further ribbonizing process. A method of cryptographically transforming data text c comprises the step of generating an integer representation m of the data text c according tom=cd whered is a predetermined exponent. Air or water or both inflate the bladder using a pump controlled by buttons and a pressure gauge adjacent to the handle. Each of the at least one first supporting portion is positioned on a respective one of the at least one first circuit portion, and each of the at least one second supporting portion is positioned on a respective one of the at least one auxiliary pad. A method for operating an optional key map of a portable terminal according to the present invention includes displaying at least one basic key map generated according to a predetermined standard, and displaying at least one optional key map linked to the at least one basic key map along with the at least one basic key map. The Voltage Sense circuit added to each converter generates a Simulated Output Voltage, which predicts how would the output voltage of each particular unit rise during the start-up with enabled synchronous rectifiers if that particular unit were to operate alone.
