Abstract: A head-activated fluoroscopic control which is characterized in a preferred embodiment by a continuous wave infrared transmitter located in a cartridge adapted for attachment to eyeglasses, a headband or other headpiece worn by a surgeon or attending physician and a detector or receiver tuned to the frequency of the continuous wave infrared transmitter for receiving a partially collimated infrared signal beam and activating a fluoroscope. The infrared transmitter emits the collimated beam and the beam is received by the receiver when the surgeon's head is turned toward the fluoroscope monitor upon which the receiver rests or in which the receiver is mounted, to facilitate selective operation of the fluoroscope during surgery.

Abstract: A propelled water craft which is generally characterized by a twin pontoon barge having a generally flat deck, a pair of seat pedestals mounted on the deck and carrying rotatable, folding seats, and further characterized by port and starboard variable speed, reversible motors mounted in the rear of the water craft behind each one of the pontoons and operative responsive to on-off pressure switches mounted on a portable support, and forward and reverse thrust switches, and speed control means.
