    摘要: A method includes extracting phase due to fringe count error (FCE) in spectra formed by an interferometer. The exemplary method includes the steps of: (a) forming an earth scene spectrum; (b) forming a background reference spectrum; and (c) forming a phase extraction function, Rk, where k is a kth channel of the interferometer. The phase extraction function is formed from the earth scene spectrum and background reference spectrum. The method may also include the steps of (d) using recursive least squares (RLS) to extract phase from the Rk function; and (e) providing the extracted phase to a user to correct the FCE. Step (c) may include forming a term in the Rk function that includes a positive or a negative sign of a square root. Step (d) may include determining whether the sign is negative or positive using the RLS.

    摘要: Methods of operating an SIP load balancer, one or more SIP server nodes and/or one or more SIP server instances are provided that efficiently manage a processing load. Configurations for an SIP load balancer, one or more SIP server nodes and/or one or more SIP server instances to enable efficient management of a processing load are also described. In certain ones of these, state data for a set of SIP processes may be sent from a SIP server instance and used by a SIP load balancer to remove inactive SIP processes from a data structure. The management of a processing load comprising a number of SIP processes following the failure of a SIP server node and/or a SIP server instance is also provided.

    摘要: An apparatus and method for digitizing an analog signal and optimizing the dynamic range of the digitized signal. Dual analog-to-digital converters are preceded by respective amplifiers with different gains for receiving an analog input signal. The digital output signal from the analog-to digital converter preceded by the amplifier of higher gain is selected and stored when it is not clipped. Otherwise, the analog-to-digital converter preceded by the amplifier of lower gain is selected and its digital output signal is stored. Once digital memory is filled, an adaptive formatting program selects the most appropriate parts of the memory words to achieve maximum resolution and dynamic range in an output word size.
