Disclosed herein, for example, are methods and apparatus for forming carton blanks. The communication device sequentially initiates communication with a contact either automatically or in response to user input using various communication means associated with the contact. The channel collects and retains any bleed-through of the encapsulating material. Control signals for actuating the discrete light sources are synchronized with frames captured by a camera, such that the camera never sees the transitions from illuminating one discrete light source of the array to illuminating another. The system may also include a battery back-up unit element disposed within the chassis.
