Abstract: An illumination and detection architecture that illuminates a target for detecting a material of interest. The architecture includes an illumination component that illuminates the target using a predetermined light wavelength known to energize and thereby cause a detectable change in the desired chemical and/or compounds associated with the target in a particular way. The change is then captured by an image capture system and processed to determine the presence or absence detected of the desired material of interest at the target.

Abstract: A dynamic sensor regulator that provides a mechanism for introducing desirable tonal artifacts in component-based guitar amplifier systems by inducing voltage fluctuations into the power supply of a preamplifier. The dynamic sensor regulator comprises a regulator circuit, connected to an amplifier that is connected to a converter circuit that is connected to a variable control circuit. The amplifier includes a floating bias circuit that dynamically adjusts the bias state of an output driving amplifier in response to signal fluctuations of the regulator output signal. A transformer is connected to the amplifier output and once the transformer's saturation point has been reached, the saturation of the transformer increases proportionally with the amplifier's input signal while the regulated output signal remains constant, emulating amplifier overload and saturation.
