    Abstract: A system and a methodology to improve the end-user quality of service both in terms of response time and reliability for the transport of in-call DTMF signals in wireless systems, particularly in geostationary mobile satellite systems. The methodology encompasses several techniques to provide acceptable end-to-end quality of service for DTMF. A technique is applicable for transport of DTMF in the wireless subscriber to network direction, where DTMF digits are carried in the form of an out-band message. The central part of the technique is to allow multiple key presses in the same message, thereby increasing efficiency and throughput in long-delay environment. Another technique utilizes the vocoder's functionality to carry DTMF in-band, thereby reducing system complexity. The scheme makes the use of an integrated DTMF detector which can classify a given frame of signal into several classes so that the DTMF encoded packet can carry a unique pattern across the air-interface to the voice decoder at AT, which is capable of identifying the pattern. Another technique pertains to the use of a message based DTMF transport between two-ATs on a separate logical channel with a unique Service Access point Identifier (SAPI) providing guaranteed service for DTMF transport in an AT-AT call.

    Abstract: A method of forming an array of nanostructures includes forming a plurality of seed points on a surface of a substrate, and growing masks from the seed points to create masked regions of the substrate underlying the masks. A remainder of the substrate comprises an unmasked region. Each mask and masked region increase in size with growth time while the unmasked region of the substrate decreases in size. During the growing, the unmasked region is etched to remove material from the substrate in a depth direction, and, simultaneously, unetched structures are formed from the masked regions of the substrate underlying the masks. Each of the unetched structures has a lateral size that increases with depth.
