Abstract: Disclosed is an aircraft collision avoidance system having remote triggering means, multicolored lamp display, audible alarm, and a stroboscopic light for providing adequate early warning to an aircraft tug operator and other surrounding individuals that a possible emergency situation may exist. The system comprises four assemblies: (1.) a portable unit; (2.) a tug unit; (3.) a station unit; and, (4.) one or more hand wand transmitters. The station unit comprises a strobe light mounted to a building or gate and is positioned so as to be visible by a tug operator and flightcrew. The tug unit comprises an audible alarm mounted within the tug vehicle which is audible to the tug operator when triggered and a highly visible strobe light. The portable unit comprises an audible alarm that sounds when triggered and a highly visible strobe light. The portable unit may be utilized in place of the tug unit or may be utilized in conjunction with the tug unit at other positions, depending on the degree of warning needed.

Abstract: The pelvic bone splitter (10) has a shaft (12) with a slot (18) and a knurled surface (26) on its free end (24). A first end (34) of a blade (14) is pivotally retained in the slot (18) by a pivot pin (16). Cutting edges (40, 42 and 44) on the blade (14) are movable into the slot (18). During use, a free end (24) of the shaft (12) is passed under the pelvic girdle (64) and out through an aperture (66) in the hide (68). Pressure is applied to the hand grip (50) to move the cutting edge (42) toward the slot (18), compress the pelvic girdle (64) between the cutting edge (42) and the anvil surfaces (28 and 30) and split the pelvic girdle.
