Abstract: A hand sanitizer dispenser having a dispenser mechanism. The device may be microprocessor controlled and may time stamp and log actuations of the dispenser mechanism. Log entries may be associated or correlated with a patient and may be recorded in the patient's electronic medical records. The dispenser may also include an audio component adapted to issue verbal reminders and tonal reminders from a schedule of reminders. The schedule of reminders may be derived from entries in the patient's electronic medical records such as meal times, appointments with specialists, and other triggering events where hygiene may be advantageously practiced.

Abstract: A system, method and apparatus for anatomical mapping utilizing optical coherence tomography. In the present invention, 3-dimensional fundus intensity imagery can be acquired from a scanning of light back-reflected from an eye. The scanning can include spectral domain scanning, as an example. A fundus intensity image can be acquired in real-time. The 3-dimensional data set can be reduced to generate an anatomical mapping, such as an edema mapping and a thickness mapping. Optionally, a partial fundus intensity image can be produced from the scanning of the eye to generate an en face view of the retinal structure of the eye without first requiring a full segmentation of the 3-D data set. Advantageously, the system, method and apparatus of the present invention can provide quantitative three-dimensional information about the spatial location and extent of macular edema and other pathologies.

Abstract: A system, method and apparatus for speckle noise removal based upon structural correlation in an OCT imaging system. In accordance with the present invention, several two- or three-dimensional OCT image scans can be acquired for processing by an adaptive algorithm. Specifically, at each image point an image intensity can be computed that quantifies a measure of dispersion of the image values in a particular direction with respect to their mean. Subsequently, a direction ?0(x, y) can be selected which minimizes the energy function at the given pixel (x, y). Finally, a value proportional to a local average of the input image around the point (x, y) can be chosen for the output image. In this way speckle noise can be minimized if not removed while, at the same time, maintaining the image substantially free of obvious artifacts.
