A system includes an accessory for a mobile computing device, the accessory including a body defining an interior configured to secure a mobile computing device, a communications module configured to receive an electronic command to eject a projectile, and a projectile launcher, coupled to the body, configured to eject a projectile in response to the command. The system also includes a projectile disposed in the projectile launcher.

A tracking device is configured to detach from a launched projectile to remain in an animal when the projectile proceeds completely through the animal. The tracking device can be attached to the end of an arrow shaft and provide the nock of the arrow. A decelerator such as a barb, an offset fin, or a reverse helical projection is provided to aid in detachment of the tracking device from the arrow shaft as it passes through the animal. The tracking device remains embedded in the animal so that the animal can be tracked instead of the arrow.

An autonomous weapon system for improved guidance of a projectile for homing a target includes a guided projectile including at least one sensor and a carrier projectile and at least one guidance and reconnaissance unit including a transmitter for communication via light. The system uses emitted light for both positioning and communication of target coordinates which provides an accurate and cost effective system for combatting point and surface targets by indirect fire.

An electronics ordnance delivery system includes an electronics component that is to be delivered into a target. The electronics component is enveloped by a protective housing that assists in the delivery of the electronics component payload. The protective housing is made of an electronically-conductive material such that it can function as an antenna for the transmission of signals by a transmitter component of the electronics component.

A smart bullet configured for monitoring, tracking, and facilitating initial care of the gunshot victim of the bullet.

According to a first aspect of the present invention, there is provided a reconnaissance and communication assembly, adapted to be launched from a gun barrel into the air. The assembly comprises a carrier (with a cavity) and a payload (within the cavity). The payload is arranged to be controllably expelled from the carrier and once expelled from the carrier, the payload transmits a signal.

A system and method of locating a target and presenting the location via augmented reality. The inventive subject matter includes a projectile that can transmit information including location information to other computing devices. These computing devices can then use the location information to determine the relative location of the projectile relative to the computing device and generate a visual representation of the location of the projectile on an augmented reality display such that the location of the target is overlaid over a real-world view through the display.

A lethal projectile for immobilizing a target is capable of self-separating or otherwise opening after launch by a launcher and may release a payload prior to impact with a target. Opening may caused after an energy storage means of the projectile is charged beyond a threshold energy level. Charging of the energy storage means may be accomplished through dynamic induction when the projectile moves through a stationary magnetic field generated by a magnet of the launcher prior to launch, A control circuit can increase or decrease the magnetic field strength of the magnetic field in order to control the distance at which the projectile releases its payload, A rangefinder may provide distance information to the control circuit for charging the energy storage means to a specific energy level associated with the distance to a target.

An arrow includes an arrowhead, a shaft, a nock, and an internal cavity. The internal cavity includes a camera.
