Abstract: The head pose of a motor vehicle driver with respect to a vehicle frame of reference is assessed with a relative motion sensor positioned rearward of the driver's head, such as in or on the headrest of the driver's seat. The relative motion sensor detects changes in the position of the driver's head, and the detected changes are used to determine the driver's head pose, and specifically, whether the head pose is forward-looking (i.e., with the driver paying attention to the forward field-of-view) or non-forward-looking. The determined head pose is assumed to be initially forward-looking, and is thereafter biased toward forward-looking whenever driver behavior characteristic of a forward-looking head pose is recognized.

Abstract: Surface enhanced Raman scattering (SERS) spectra of 4-mercaptobenzoic acid (4-MBA) self-assembled monolayers (SAMs) on gold substrates is presented for SAMs onto which gold nanoparticles of various shapes have been electrostatically immobilized. SERS spectra of 4-MBA SAMs are enhanced in the presence of immobilized gold nanocrystals by a factor of 107-109 relative to 4-MBA in solution. Large enhancement factors are a likely result of plasmon coupling between the nanoparticles (localized surface plasmon) and the smooth gold substrate (surface plasmon polariton), creating large localized electromagnetic fields at their interface, where 4-MBA molecules reside in this sandwich architecture. Moreover, enhancement factors depend on nanoparticle shape, and vary by a factor of 102.

Abstract: The embodiments describe calculating and store scaling information based on processing input binary image data. By manipulating data that is received in binary format, the most cost effective method for scaling may be chosen. The input image data is scanned, a resolution (e.g., for display or output) is determined and a scaling method is determined. If the input binary image data needs to be scaled down to a smaller resolution, the binary image data is processed and scaled and then converted to grayscale image data. If the image data must be scaled to a larger resolution, the input binary image data is first converted to grayscale image data before processing using a segmentation tag-based scaling method. The scaled image data may then be output to an output device, such as a display, printer, or image output terminal.
