Abstract: A protective cover for a cell phone is formed as a trough having a generally rectangular rimmed base configured to embrace a rear surface and four sides of the cell phone. The cover has an EMF shield rotatable among closed, intermediate, and open positions. The EMF shield in the closed position lies parallel to and screens a display surface opposite the rear surface of the cell phone. The EMF shield in the intermediate position provides a stand configured to support the display surface at a landscape orientation angled with respect to horizontal. The EMF shield in the closed position lies parallel to and screens the rear surface. Rotation of the EMF shield may be effected by a double living hinge strengthened by a metal mesh that forms a Faraday cage for shielding a user from EMF generated by the cell phone.

Abstract: A set of wiper blade assemblies built into a fixed frame and along the edge of a movable planar surface whereby the opening and closing of a movable panel engages both the wipers to wipe two parallel planar surfaces. The fixed wiper mounted to the frame squeegees water and particles away when the movable plane or door is slid opened or closed. Simultaneously, the movable panel with a mounted wiper serves to wipe the other parallel planar surface. Another embodiment has more than two wiper assemblies mounted along the edge of two or more planar surfaces and a fixed wiper across the frame whereby moving any of the movable plane engages all the wipers to wipe water and particles away from the planar surfaces. Another embodiment has one fixed wiper assembly mounted from the top to the bottom of the frame whereby moving a single plane engages the wiper to wipe the surface of the single panel.
