Abstract: An automated (robotic) floor cleaner (100) is adapted to allow sterile cleaning of sensitive environments, such as hospital room. In particular, the floor-cleaner chassis (124) is redesigned to be mounted on a deck (102) containing cleaning devices that contact the floor. The cleaning devices mounted on the deck (102) include vacuum head (132), brushes (120), cleaning fluid sprays (128), and conceivably sanitizing devices such as UV germicidal light, are provided pre-sterilized. As such, the adapted floor-cleaner chassis (124) allows the deck (102) to be mounted to the bottom of the chassis (124), the floor-cleaner (100) is then used to clean a floor, after which, the deck (102) is removed from the chassis (124) and disposed. The robotic-floor cleaner (100) and sterilization system cleans floor between or even during cases. Further, the robotic floor cleaner (100) reduces the “turnover time” required between cases, as it operates simultaneously while the staff prepares the room for the next case.

Abstract: An acrylic or other polymer composition, optionally containing aluminum trihydrate, and having undoped and/or doped titanium dioxide dispersed evenly throughout is disclosed. Said composition provides a sterile surface which can be renewed. Said composition provides a highly sterile surface upon photoactivation of the surface by at least either low-level ultraviolet irradiation or ambient/natural light (as when using doped titanium dioxide). A method of using such a surface material is also disclosed. Said acrylic or other polymer composition may be adhered onto a polycarbonate or other polymeric backing, optionally by an intervening layer of a third polymer. The resulting acrylic or other polymer/polycarbonate or other polymer combination is adapted to provide ambient lighting when exposed to a light source.

Abstract: A graphical-user-interface manipulable lighting system is disclosed in which a light source having a position of focus is moved by an articulator adapted to receive and send signals through a control box indicating the current and intended positions of the focus of the light source, and further a computer interface operating wirelessly which graphically displays the current position of the light source and is adapted to allow a user to drag an icon indicating the current position of the light source onto a new intended position thereby resulting in the movement of the light source to the new position.
