Abstract: A device and system for generating a broadband excitation signal and corresponding excitation field to a substance under test in an NMR system is presented. The excitation signal is generated, according to a broadband transmitter, to a coil in the NMR system. A corresponding broadband receiver is also presented that acquires a response signal resulting from a response field emanating from the substance under test. Neither the transmitter nor the receiver require that the frequency of operation be determined according to a particular configuration of electrical devices to determine a resonance characteristic that tunes to a particular operational frequency. Rather, the operational frequency is determined according to control and driver devices triggered according to command and control signals in the case of the transmitter, and according to reactive elements, that are not configured as a tuned circuit, in the case of the receiver.

Abstract: A programmable interface module includes a linear power regulator to control and provide power to interfaced components on an as needed basis. The interface module is implemented in, for example, a sensor pack and multiplexed to a plurality of sensor modules. In a first mode, the linear voltage regulator provides a relatively small amount of power which allows a sensor module to output a signal responsive to detecting an environmental condition (e.g., gamma or x-ray radiation, extreme temperatures, etc.). The interface module can switch the linear voltage regulator to a second mode in which the linear voltage regulator ramps up the amount of power provided to a detecting sensor module. The sensor module can then provide a level indicative of a concentration or intensity of the environmental condition. If the level surpasses a predetermined threshold, the senor pack can output an alert signal to security server.

In order to improve the linear performance of the probe, feedback control was employed. A position sensor along with supporting electronics was designed to provide control signal for the feedback system.
