US Patent 9044863 Polarized enhanced confidentiality in mobile camera applications

A system for selectively controlling visibility of information and for reducing or eliminating light energy in a robotic telepresence environment is provided. The system includes a robotic device in a work environment that is occupied or operated by a pilot at a station in a workspace remote from location of the robot in the work environment, a camera operably attached to the robotic device, a primary polarizing filter adjustably attached to the camera, a viewing area, at least one light source remote from the camera, and at least one secondary polarizing filter. The primary and at least one secondary polarizing filter can be adjusted to vary the lighting and artifacts seen by the pilot.
