Abstract: A device for defogging and deicing windshields and other glass surfaces is described. The device comprises two air channels that each circumscribe a glass surface, one channel along the interior edge of the glass surface and the other along the exterior edge. Each of the channels feature numerous outlets that disperse hot air onto the glass surface, thereby blanketing the glass surface in hot air on both sides. The two channels may be incorporated into a single boot made of rubber or some other material that doubles as a gasket to hold the windshield or other window in place. An electric heating element may be incorporated into the device so that warmed engine coolant passing through a traditional vehicle heater system coil is unnecessary. Several such devices may be incorporated into a vehicle to heat each glass surface individually.

Abstract: A portable liquid container and dispenser system having a bladder for holding a liquid, a belt for securing the bladder about the waist of a user, a pump in fluid connection with the bladder, a power source for the pump, and a hose in fluid connection with the pump for delivering the liquid to a user. The bladder may be disposed within a protective pouch, and a remote switch may be provided to facilitate easy activation and deactivation of the pump. The switch may be located on the hose for added convenience.
