Disclosed are soft, high refractive index, acrylic device materials. In one step, a first number of personal communication modes associated with the originating end is retrieved. The configuration advantageously allows the user to determine when values are greater than or less than a predefined value while employing a reduced number of lookup tables in the field programmable gate array. The session key, which is used both for encryption and decryption of the paging file data, is stored in volatile memory, so that the key is not persisted across boots of the machine. In one embodiment, a portion of the flexible display may be utilized when the flexible display is stored in said first housing.
