The process includes the method of determining a current pitch angle and a current angular rocking rate of the model vehicle and accelerating or decelerating a mass on the model vehicle based on the current pitch angle and the current angular rocking rate of the model vehicle to create a rocking motion by the model vehicle. In addition, the method also includes terminating the self-righting process when the model vehicle is upright. In which, the model vehicle body contacts the ground and provides a fulcrum for the rocking motion by the model vehicle.

Abstract: A composite string such as a bowstring or cable used in archery bows and crossbows includes multiple types of strands or multiple types of materials in its strands. The different materials or strands have different properties such as stiffness, strength, abrasion resistance, or density. The string therefore has specialized properties such as different properties when subjected to different tensile loads or optimized durability. A serving material is also used to bind strands of material to the string for silencing, vibration dampening, improving durability, or providing additional rigidity to select portions of the string.

Abstract: The invention concerns a gaming device (1) to throw and catch a ball or a shuttlecock comprising a basket (20) structured around two rigid walls (21, 23) and elastic means (22, 24) for throwing the ball or the shuttlecock with a certain velocity by stretching the gaming device (1), while making it easier to catch the projectile in the structured basket (20) when the gaming device (1) is in resting position.

Abstract: A high impact strength nock assembly that couples with, and decouples from, a bushing mounted in an arrow. The forces applied to the nock during launch are translated to the arrow through the bushing, greatly extending arrow life. For lighted nock applications, the nock translates within the bushing during launch to activate the light. A battery stop is coupled to the battery and releasably coupled within the center opening of the bushing that resists longitudinal translation of the battery relative to the bushing. Consequently, the light can be deactivated without removing the lighted nock assembly from the bushing. The entire lighted nock assembly is removable from the bushing for maintenance and replacement.

Abstract: An airsoft magazine that provides an automated feed mechanism of pellets housed in the magazine. The airsoft magazine includes an outer shell housing an inner shell, the inner shell constructed of two symmetrical, half shells. The inner shell includes a feed mechanism operated by a motor powered by a battery. The feed mechanism includes a spinning gear mechanism rotated by the motor to transfer the pellets from a loading chamber to an exit chamber from which the pellets are ejected from the magazine. A first sensor is disposed in the inner shell to output a signal when the sensor detects the pellets passing through the exit chamber and ejected from the magazine. A circuit board for receiving the signal from the sensor turns on the motor and transfers the pellets from the loading chamber to the exit chamber from which the pellets are ejected from the magazine.

Abstract: A toy comprising a rotor and a centrally arranged capsule, wherein the capsule comprises an actuator mechanism that is configured to cooperate with a launch element and an actuator element, wherein the actuator element is configured for engaging with the actuator mechanism to transfer a momentum to the rotor, whereby the rotor can rotate and be launched from the launch element, wherein the capsule is a separate part relative to the rotor, and the capsule comprises at least two capsule parts whereby the two capsule parts can be opened when the rotor and the capsule are separated, and wherein rotor, capsule and actuator mechanism are connected to each other to the effect that the momentum from the actuator element is transferred to the actuator mechanism that conveys the momentum on from the capsule to the rotor, when the at least to capsule parts are closed.

Abstract: A burst device of a toy gun (8) with a mechanical box (800) includes a sliding mechanism (10), a pressing mechanism (20) and a stop part (30).
