Abstract: There is described herein an interactive time management tool. A calendar view is presented showing scheduled events on a daily, weekly, monthly, and/or yearly basis. A visual representation, such as an icon, is available for selection in combination with a previously scheduled event to cause the event to automatically be moved from its original time slot to a time slot corresponding to an actual or present time slot. The calendar is therefore updated in real time using minimal effort in order to more accurately represent how a user's time was spent over a given period of time.

Abstract: A simulator, for use with stereoradiographs, as a neurosurgical aid in locating potential paths for the implantation of probes in selected locations of the brain. It has a support, on the top surface of which is mounted a pair of radiographs disposed for stereoscopic viewing. An elongated ruler lies over the stereoradiographs and is movable in translation over them. A pair of transparent flat plotting plates are mounted on the ruler and are slidable therealong. Each plotting plate has a circular hole and a transparent circular disc is rotatable around this hole; a radial line extending from the center of the disc giving a "floating line" in the stereoscopically viewed model to simulate a probe to be implanted in the brain.
