Abstract: Various embodiments provide methods, apparatuses, systems, or computer program products for providing dynamic control of a signal. In an example embodiment, a system comprises a signal generator, a controller configured to control operation of the signal generator, a first signal path between the signal generator and an output connected to an electrode of an ion trap, and a selectively connectable second signal path between the signal generator and the output to bypass the low pass filter. The signal generator is configured to generate a signal comprising a first frequency component having a first range of frequencies and/or a second frequency component having a second range of frequencies higher than the first range of frequencies. The first signal path comprises a low pass filter to filter noise above the first range of frequencies. The second signal path comprises a bandpass filter to permit the second frequency component to pass from the signal generator to the output.

Abstract: Disclosed is a system and method for assessing environmental risk associated with a parcel of real property through the form of reports which can be generated without the significant expense and time delay of a physical site inspection. Also disclosed is a method to facilitate contaminated land transactions by reports that provide consultancy, legal, and/or financial advice based on factors determined in the absence of a property site visit. In one aspect, the disclosed method comprises several steps based on certain determinations made using commercially-available and publicly-available databases. In another aspect, the disclosed method is a way of providing financial assurance via an insurance policy with the steps of supplying an environmental risk report and automatically supplying an environmental insurance quote based upon the environmental risk report.
