A projectile deployment system includes an entangling projectile having a pair of anchors and a tether connecting the pellets. A projectile casing includes a pair of sockets, each socket sized to carry one of the pair of anchors. At least one pressure source is capable of expelling one or both of the anchors from the projectile casing toward a subject. At least one of the entangling projectile or the projectile casing can be configured such that the pair of anchors travel toward the subject with differing flight characteristics after being expelled from the projectile casing.

An apparatus for managing agricultural crops includes a vehicle and a user interface. The vehicle includes a navigation system, one or more vision systems, one or more removal tools, and a control system. The control system can include a data processing system, a data storage system, and a targeting system. The apparatus can be used to carry out one or more methods for managing agricultural crops, such as, for example, utilizing the vision system to capture images of an item to be targeted for removal by the removal tool, and utilizing the control system to process the images and position the removal tool to remove the item.

A projectile component that can be removably attached to a flying vehicle is disclosed. The projectile component includes a net configured in the projectile component, a receiving cavity configured in the projectile component, and a weight attached to the net via a string. The weight can be configured in the receiving cavity in preparation for firing the net from the projectile component. In order to entangle a target flying vehicle in the net, a cocklebur associated with the weight is included. Upon firing the net from the projectile component, and upon the net engaging with a target device, the cocklebur becomes entangled with the net to secure the target flying vehicle. A drawstring structure associated with the net can also be used to ensure that the net envelops and captures the target flying vehicle.

A projectile cartridge that can be removably attached to a flying vehicle is disclosed. A system can include a first flying vehicle, a projectile attachment mechanism configured with the first flying vehicle, a projectile cartridge that contains a projectile, the projectile cartridge being removably attachable to the projectile attachment mechanism, a weight attached to the projectile, the weight being configured in a releasable configuration in the projectile cartridge and a drawstring configured with the projectile. After firing the projectile, when tension is applied to the drawstring as the projectile approaches or envelops a second flying vehicle, the tension can cause the drawstring to close the projectile down to secure the second flying vehicle.

A pneumatic rescue system; the pneumatic rescue system includes a housing having a tank-section, a connector-section, and a barrel-section; and a flotation-device configured to provide buoyancy to an individual stranded in a body of water. The pneumatic rescue system provides a rapid response designed to reach stranded individuals by firing the flotation-device to the individual.

A stationary life-saving unit launcher. The stationary life-saving unit launcher includes: a base; a compressed gas tank mounted to an upper portion of the base and supplying compressed gas; a frame mounted above the base by being spaced apart by a predetermined distance therefrom; and a launch unit mounted to the frame and firing a life-saving unit by using the impact force of the compressed gas supplied from the compressed gas tank. The launch unit is capable of firing a projectile without a loading motion for firing the life-saving unit after the mounting thereof.

A barrel catch of a toy gun has a barrel through hole with diameter larger than outer circumference of the barrel so that the barrel penetrates through hole center. The barrel catch includes a barrel fitting portion fitted/attached to the barrel on the inner circumference of the hole opposite to the pressing portion exposed from an opening in a barrel attachment portion of a toy gun body. The barrel catch is housed in a housing portion of the toy gun body slidably in the direction defined by the pressing portion and the opposite portion of the pressing portion. The barrel includes a barrel catch fitting portion fittable to the barrel fitting portion of the barrel catch upon penetration of the barrel through the barrel catch. The barrel slidably penetrates the barrel through hole of the barrel catch in the direction defined by the pressing portion and the opposite portion.
