    摘要： A sensor provides an analog sensor output signal that is first converted by a A/D converter, followed by a digital signal processor having a digital signal output that is converted to an analog signal by way of a D/A converter so as to provide an analog information output signal indicative of a parameter quantity intended to be sensed. An analog dither signal and/or a digital dither signal is provided for modulating the A/D converter input signal and/or D/A converter input signal, respectively, separately, or in combination, to enhance dynamic range accuracy of the resultant analog information output signal representative of the quantity of the parameter intended to be sensed.

    摘要： A system and method for achieving, while using a laser and optical fibers, high signal-to-noise ratio. In particular, the system splits an incoming main light signal into two orthogonal polarization states, which then propagate through an optical circuit before recombining. The use of appropriate path differences ensures that the system is immune from the conversion of mode partition noise to intensity noise arising from the interference between parasitic light waves which traveled through the system in undesired polarization states.

    摘要： Peptides which bind to selected ligands are identified by screening peptide libraries which encode a random or controlled collection of amino acid sequences. A rapid and convenient iterative strategy is employed to determine the peptide sequences which bind to the ligand of interest. The peptides so identified can be used as diagnostic or therapeutic agents, or in the design of lead compounds for such uses.

    摘要： Systems and methods according to these exemplary embodiments provide for methods and systems related to optical current sensors used to monitor standby power transformers, specifically fiber optical current and voltage sensors and, more particularly, to applications involving filters for use in such sensors, such as frequency tracking comb filters. According to one embodiment, a method for monitoring a connection condition of a stand by power transformer includes the steps of measuring a current flowing through a high voltage side of the standby power transformer using at least one optical current sensor disposed proximate to a current flow path of the high voltage side, using a comb filter to filter the measured current, determining whether the filtered, measured current is less than a predetermined threshold value; and generating an alarm indication that the high voltage side of the standby power transformer is unconnected.
