Abstract
Abstract This invention teaches a safety for preventing unauthorized firing of a weapon (H) of the type having a trigger (19) and mechanical firing mechanism (21) for firing the weapon. A solenoid (S) controllably actuates or deactuates upon the application of an electrical signal. A decoder (D) is mounted with the weapon for detecting a signal from an authorized user and selectively activating the solenoid upon the signal from the authorized user. Such decoder (D) is electrically connected to at least a power source (P) and to the solenoid (S). An encoder (E) creates the signal indicating that the possessor is authorized to use the weapon. A linkage (L) connects the solenoid (S) and the firing mechanism (F) for controllably enabling or disabling the weapon from being fired upon the desired activation of the solenoid.
