Description

TECHNICAL FIELD

This invention relates generally to the weapons field, and more specifically to a weapon with an input device, such as a camera or a microphone.

BACKGROUND

Stun guns are less-than-lethal weapons used by army personnel and police officers as protection against terrorist and criminal attacks. Stun guns work by applying a high-voltage, but low-current, electrical charge. Since the nervous system in the human body works by sending electrical charges through neural pathways, the electrical charge provided by a stun gun “confuses” the nervous system. This confusion can cause a recipient of an electrical charge from a stun gun to feel paralyzed for a brief instant, or can cause a spasm or convulsion in an area of their body. Because stun guns are considered less-than-lethal, they have become a weapon of choice by many law enforcement agencies throughout the world.

Stun guns could, however, be abused by law enforcement officials because of the potential to cause temporary paralysis without leaving substantial visible marks on the human body. Careful training largely eliminates this concern. Nevertheless, there is a need in the stun gun field, and in the broader weapon field, to create a system that allows a user to restrain a recipient during a terrorist or criminal attack and that also increases the accountability of the user.
