We report on tests of an x-ray beam size monitor based on coded aperture imaging[1]. This technique uses a mask pattern to modulate incoming photons, with the resulting image being deconvolved through the mask and detector responses, including the effects of diffraction and attenuation materials in the path, over the spectral and angular distribution of the synchrotron radiation generated by th...

This paper describes the first of two experiments examining the safety and usability of the Siemens Ali-Scout navigation system, an in-vehicle interface that provides turn-by-turn visual and voice guidance. A total of 54 drivers varying in age drove an instrumented car to four destinations, twice using the Ali-Scout and, subsequently, once using experimenter verbal guidance. Subjects were teste...
