Abstract: A bow assembly includes a bow body assembly that pulls a string to shoot an arrow by a force generated by a rebound of an elastic body, where the bow body assembly is pivotally connected to a winding assembly for winding the string; and the winding assembly slides from a first position of the bow body assembly to a second position of the bow body assembly through a sliding assembly. The bow assembly involves manual winding, but the manual winding process will not exert any force on a limb, and a winding wheel can be moved by driving the sliding assembly by pedaling. In a shooting phase, the winding assembly is fixed relative to a bow body. In addition, the energy efficiency enhancer enables the winding wheel to continue to rotate after a limited number of revolutions. Further, as the winding wheel will not stop abruptly, noise is reduced.

Abstract: A dual spreading arrowhead has components and operations that cut on contact with an animal. The dual spreading arrowhead has a left blade and a right blade mutually pinned to a head. The head secures to a shaft of an arrow. The left blade and the right blade each have a pointed tip and two sharpened edges. Opposite the tip, each blade has a rounded foot that travels within a slot through the head and upon a shaped spacer. Between the foot and the tip, each blade has a spine not sharpened. The arrowhead has a flight position with the tips near each other but not overlapped and a deployed position with the blades rotated outwardly and the sharpened edges mutually forward. The arrowhead utilizes the momentum of the flying arrow shaft to adjust the invention from the flight position to the deployed position.

Abstract: A crossbow includes a frame, where the frame is provided with an arrow track for placing an arrow; the crossbow includes at least one limb; the limb includes a fixed end and a movable end; the movable end is moved toward the fixed end under pressure, such that two sections bent in opposite directions are formed on the limb to make the limb wave-shaped; the movable end is moved in a reverse direction to make the limb restored; and a primary string of the crossbow is directly or indirectly connected to the movable end of the limb. The limb of the crossbow can generate large elastic potential energy and can reduce the kinetic energy consumed by translation, and avoids the problem of different strokes between multiple limbs. The crossbow prevents the winding wheels from translating to consume the kinetic energy, such that the arrow can gain sufficient kinetic energy.

Abstract: Systems and methods of detecting launch of a model rocket are described herein. A mechanically implemented launch accelerometer may be disposed on a model rocket. The launch accelerometer may detect acceleration of the rocket by a mass of the launch accelerometer moving relative to the rocket and against a spring force based on the rocket acceleration. The mass may comprise a first electrical contact that may contact a second electrical contact when the mass is accelerated beyond a threshold, which is indicative of launch of the rocket. The contact between the first electrical contact and the second electrical contact may complete an electrical circuit. Furthermore, at least one pin may lock the mass in a position allowing the electrical circuit to remain complete.
