Abstract: The present invention generally relates to an improved foam dart that operates with improved accuracy. The shaft of the foam dart is shaped with indentions that direct airflow around the dart to improve its accuracy. The dart tip is also connected through a rigid neck portion that further improves the accuracy of the dart during use. An alternative embodiment allows the user to place a pop cap within the dart tip that will explode to cause a loud bang when the dart contacts a hard object at the end of its flight. Side vents direct exhaust gases away from the target to improve safety.

Abstract: The present invention provides methods and apparatuses related to applying darts, such as tranquilizers and inoculations, to animals, and more particularly to such application in conditions where human presence in proximity to the animal is undesirable. Example embodiments of the present invention allow darts to be projected to animals while a human operator controls the device from a remote location. The remote location of the human operator reduces the need to chase or otherwise stress the animals. Inclusion of a human operator, as compared to fully automatic systems, reduces the chance of projecting darts to wrong targets such as incorrect species, reduces the chance of malfunction or damage to the system, and provides an ability to monitor in real time the application and effect of the darts.

The method includes the steps of filling a frangible container with riboflavin powder and then attaching the container to the tip of the arrowhead to produce the converted arrowhead so that if the converted arrowhead is fired at and hits a game animal to wound the game animal, the frangible container can break so that the riboflavin powder is distributed into an environment where said animal was hit and into any blood flowing from said wound to better enable the tracking of the wounded animal.

Abstract: The present invention is a bleed out arrow that allows a wounded animal to bleed out and die more quickly. The arrow is provided with a hollow shaft with openings in it that serve as conduits for blood to exit the animal's body when the arrow has lodged in the wounded animal's body. The openings are in the form of slits that are located at the front end of the shaft just behind the blades of the arrow tip and aligned longitudinally with the blades of the arrow tip, at the rear end of the shaft just behind the fletches and aligned longitudinally with the fletches, and in the middle of the shaft, preferably behind the blades and preferably aligned longitudinally with the blades of the arrow tip.

Abstract: An arrow tracking system includes an arrow that has a shaft and a head. The head is removably coupled to the shaft. The arrow is launched at an animal thereby facilitating the animal to be killed. A reservoir is coupled to the arrow and the reservoir contains a fluid dye. The fluid dye is selectively released from the reservoir when the arrow strikes the animal. Thus, the fluid dye is released into the animal's blood stream. The fluid dye reacts with blood thereby enhancing visibility of blood released from the animal thereby. Thus, the fluid dye enhances tracking the animal during hunting.

Abstract: A scent dispersion apparatus for delivery via an arrow shot by a bow. The apparatus uses an arrow tip using a compression fitting for attaching to the arrow shaft. A scent dispersion head slidably fits over the arrow tip, and contains a sponge which holds liquid scent. The arrow tip acts like a plunger to force the scent liquid out upon target impact. The arrow tip includes O-rings to hold the dispersion head in place until target impact.

Abstract: The present invention is a self-propelled arrow, consisting of an otherwise conventional hunting or target practice arrow that is propelled by CO2 and water, thus providing additional thrust to the arrow when shot from a bow. String inertia causes a CO2 filled cartridge to strike the point of a puncture means which punctures the cartridge and releases charged CO2 into a water storage chamber which charges the water inside. The charged water becomes pressurized and actuates a pliable closure membrane to an open position in check valve fashion, thus releasing the pressurized water from the water storage chamber through the propellant jets in the rear of the arrow. This system accelerates the arrow and decreases the arrow drop, thereby increasing the range and speed of the arrow immensely. The CO2 cartridges may be replaceable.

Abstract: A hunting arrow having an elastomeric device attached to the inside of the hollow shaft of the hunting arrow is used for the tracking of game animals that have been struck with the hunting arrow. The elastomeric device attached to the inside of the hollow shaft can project beyond the body of the game animal and provide a conduit for the flow of blood of the game animal even after the remaining portion of the hunting arrow projecting from the game animal has been sheared off.

Abstract: A hollow shaft hunting arrow carries a small volume of liquified carbon dioxide which is released by flash expansion upon penetration into the thorax of a game animal. The thorax is pressurized with carbon dioxide gas at sub-zero temperature to cause collapse of the lungs and fibrillation of the heart, so that the animal can be harvested on the spot, thus avoiding escape and uncertain recovery. The liquified carbon dioxide is carried in an internal reservoir and is released by flash expansion upon opening actuation of a valve closure member. The arrowhead includes a freely movable center core which is attached to an actuator shaft that is engagable with a release valve. The release valve is actuated by either piercing a metallic membrane, fracturing a glass or ceramic lens or unseating the ball closure of a ball valve assembly.

Abstract: An arrow (10) intended for dispersing olfactant (for example, for use in deer hunting) and comprising an elongate body (12) having an internal cavity (14), this cavity (14) having a container portion (18) to accommodate a frangible liquid container (20). A container rupturing device (24) is disposed within the cavity (14) adjacent the container portion (18), this device (24) being such that the arrow, with a container (20) on board, can be launched from a bow without rupturing the container (20), but that upon the arrow (10) striking a target, the device (24) will rupture the container. A wick (40) is disposed within the cavity (14) adjacent the container portion (18), this wick (40) being capable of absorbing the liquid released from the rupture of the container (20). The body (12) has apertures (42) extending from the cavity (14) to the exterior of the body (12) adjacent the wick (40), so that gas produced by evaporation of liquid absorbed on the wick (40) can diffuse out of the arrow.
