Abstract: Then apparatus for assisting in the removal of a helmet from a wearer thereof, particularly when the wearer is unconscious or injured, comprises: a framework constructed, sized and arranged to fit around a conventional helmet; an engaging mechanism for engaging the inside of a jaw covering portion on each side of the helmet; and an actuating means for causing at least one of the engaging mechanism to be moved laterally outwardly to spread apart the jaw covering portions of the helmet to facilitate removal of the helmet from the head of the wearer.

Abstract: The automatic self-filling bird feeder comprises: a container for receiving bird seed, an electrically powered blower mounted in the container and having an air outlet for supplying pressurized air to the interior of the container; a seed filling opening in the container for supplying seed to the container; a cover for the seed filling opening; a tube assembly extending from the container; an enclosed bird feeder housing mounted to the outer end of the tube assembly; circuitry for sensing the level of seed in the seed container; and circuitry responsive to the level of seed sensed in the bird feeder housing for controlling the operation of the electrically powered blower.

Abstract: A helmet removal device for removing a helmet from a head of a wearer without applying tensile forces on the neck of the wearer. The removal device includes a bladder disposed between the helmet and the top of the head with the bladder so constructed and arranged that upon inflation from a collapsed configuration to an expanded configuration, the bladder at least partially displaces the head from within the helmet. The removal device may also include an inserting tool for inserting the bladder between the helmet and head while the helmet is being worn.
