Abstract: A visual communication system that is suitable for use in connection with a display surface is disclosed. The system includes a camera or other data-capturing device that can be remotely positioned from the display surface. A control unit receives image data from the camera or data-capturing device and processes the image data to create an electronic image of the display surface.

Abstract: A method and apparatus for use with an electronic display system including a display surface wherein the system is capable of identifying a touch location on at least a portion of the display surface of a contact with the display surface, the display surface having a display area, the method for moving a cursor icon about at least a portion of the display area and comprising the steps of identifying first and second areas within the display area having first and second area surfaces, respectively, sensing a touch location on the first area surface and presenting a cursor icon on the second area surface as a function of the touch location on the first area surface.

Abstract: A method and apparatus for use with a whiteboard and an archive memory, the whiteboard having a surface for displaying images, the method for grouping presented images together for storage in the archive memory and password protecting the image groups in separate session files where a password is subsequently required to access the session file images.

Abstract: An optical-scanning system including a laser, a multi-faceted, rotational scanning mirror, and system-monitoring laser safety structure operatively and informationally connected respectively to the laser and to the mirror and the drive motor for the mirror for altering the effective power output of the laser in response to current operational status of the system as determined by current operational status of the rotating mirror. The safety structure enforces on the laser a duty cycle of operation which is less than 100-percent, causes the laser to power down to a low "sleep" operating level at times other than during a normal scanning sweep, de-powers the laser entirely if either the drive motor for the mirror is not enabled or the rotational speed of the mirror is below full normal operating speed, and also positively de-powers the laser when a user shuts down the system.
