Measurement device and method for noninvasive determination of at least one physiological parameter, the device comprising a diagnostic sensor unit for generating measurement signals, and an evaluation unit for processing the measurement signals. The compressor of the jet engine is driven directly by a dual-acting rotary piston engine. The compounds are useful, among other things, as prodrugs which can be converted under acidic conditions to thiazolium agents. The devices, systems, and methods encourage clitoral engorgement using suction over the clitoris combined with vibratory stimulation. The imaging processor associates different individual images of the multiple digitally subtracted images with different corresponding visual attributes and combines data representing the digitally subtracted images to form a composite image. The projection distance is a distance between the laser source and the projection region.
