An integrated circuit includes first and second circuits. The HMC repository includes storage of HMC objects, an HMC object model and a common interface for accessing to HMC objects. First and second signals are acquired with alternate phase encodings, and a complex difference of the acquired signals is obtained. From there, the retrieved data file may be transmitted to the authorized entity. The brightness enhancing film layers may be used to collimate light scattered from the light guide plate and thereby enhance backlight efficiency. The inner member rotates about the outer member to vary alignment of the slots and create a passageway narrower than either slot to control coating thickness.
