  • System and method for feature alignment
    Patent number: 7635433
    Abstract: In a system and method for feature alignment in chromatographic systems, the system runs a first sample through a first separation column. The system determines a first set of features for the first sample run.

    Abstract: A universal mobile telephony system (UMTS) network monitoring system for capturing intercepted UMTS data. ATM cells from a UTRAN interface may be intercepted. The UTRAN interface may be an lu interface, an lur interface, or an lub interface, which are, respectively, interfaces between a core network (CN) of the UTRAN and a radio network controller (RNC) of the UTRAN, an interface between RNCs of the UTRAN, and an interface between a Node B of the UTRAN and an RNC of the UTRAN. The ATM cells may be reassembled into UMTS packets of the UTRAN, among which user plane packets may be segregated from control plane UMTS packets based on fields and bytes of the reassembled UMTS packets.

  • Dither methods for suppression of data-dependent activity variations
    Patent number: 7626721
    Abstract: A system and method are provided for minimizing data-dependent power variations. The system and method can include summing an input with a dither signal, processing the summed signal, and substantially removing the effects of the dither signal from the output. The output is an approximation of processing to the input alone, while certain aspects of processing activity, such as temperature changes and current draw, are less dependent on input values. Variations in data-dependent activities are thus reduced. The effects of the dither signal may be removed by equivalently processing the dither signal alone, and using that result as a compensating signal to cancel components of the processed signal that result from the presence of the dither signal.
