Abstract: The present invention provides a device for guiding a medical instrument with respect to a patient. The device includes a base. The lower portion of the base includes a bottom surface having a configuration for contact with the patient. On example of such a configuration is a generally hemispherical configuration. The device also includes an instrument guide attached to the lower portion of the base. The guide has a translation axis and is configured to slideably receive the medical instrument along the translation axis. The device further includes first and second arcuate members attached to the base. The arcuate members are generally perpendicular to each other. Moreover, the device includes first and second orientation indicators connected with the first and second arcuate members.

Abstract: A substantially vertical contact scanning assembly records both sides of a document in a memory. In one embodiment, the vertical contact imaging assembly is a pair of two-dimensional sensor arrays. The document is fed between the pair of two-dimensional sensor arrays when they are space apart from each other using gravity. A registration stop positioned under the vertical contact imaging assembly aligns one edge of the document with an edge of the pair of two-dimensional sensor arrays. Once properly registered, the pair of two-dimensional sensor arrays are brought into contact with the document. After recording an electronic representation of both sides of the document, the two-dimensional sensor arrays are spaced apart from each other. Subsequently, the document is released into an output tray using gravity by lowering one edge of the registration stop.
