The disclosed embodiments relates to orienting a sound field in relation to a user and a generated set of images. The parameters of the PCVD operation are controlled such that the silica glass deposited on the interior of the tube substrate contains a non-periodic array of voids in a cladding region of the optical fiber preform. The method may provide a generic, programmable solution that can transfer any subset of register values between threads in any given order, where the source and target registers may or may not be correlated. An electrode is used for ionizing the gas prior to the gas exiting the side-ports. The network device sends a message to the first device with the redirect ID where the message indicates that a redirection occurred to the third device. Therefore, when the sample having a thickness of 100 \u03bcm is attached to the sample adhering surface, the sample protrudes 60 \u03bcm ahead of the shielding material guide surface.
