    摘要： 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.

    摘要： Imaging spectrometers can be used to generate hyperspectral images for medical diagnoses, contaminant detection, and food safety inspections, among other applications. An exemplary imaging spectrometer includes an integrated position sensing array that measures the relative positions of the interferometer components based on an interference pattern generated by illuminating the interferometer with a reference beam. Such an imaging spectrometer includes a processor that controls the interferometer component position by actuating a voice coil and several piezo-electric elements to align the components with respect to each other and to provide a desired optical path length mismatch between the interferometer arms. In some cases, the processor may use feedback and feed forward control, possibly based on the actuators' transfer functions, for more precise positioning. The processor may also implement adaptive and recursive spectral sampling to reduce the image acquisition period.
