Electronic weapon safety system

A gun safety system for use with a gun having a handle, a barrel, a firing mechanism and a safety latch comprising:

• a main housing mounted to a first side of the gun handle over a safety latch, said main housing including means for blocking access to said safety latch structured for movement from a first blocked position wherein said safety latch is inaccessible to a second unblocked position wherein said safety latch is accessible, said main housing further including means for verifying an authorized user operably connected to said means for blocking access to said safety latch, whereby said means for blocking access to said safety latch moves from said first blocked position to said second unblocked position upon verification of an authorized user and returns to said first blocked position upon absence of verification of an authorized user;
• wherein said means for blocking access to said safety latch comprises a stored energy circuit electronically interconnected to said means for verifying an authorized user, a generally vertically disposed strip having an upper end constructed of a first metal and a lower end constructed of a second dissimilar metal electronically interconnected to said stored energy circuit, and a substantially flat blocking member attached to said upper end of said strip, said strip and said blocking member being structured and disposed so that in the absence of verification of an authorized user by said means for verifying an authorized user, said blocking member covers said safety latch and upon verification of an authorized user by said means for verifying an authorized user, said stored energy circuit releases its stored energy causing said upper and lower ends of said strip to expand at different rates and said strip to bend away from its vertical position, thereby moving said blocking member away from said safety latch and making said safety latch accessible to said authorized user.

• a main housing mounted to a first side of the gun handle over a safety latch, said main housing including means for blocking access to said safety latch structured for movement from a first blocked position wherein said safety latch is inaccessible to a second unblocked position wherein said safety latch is accessible, said main housing further including means for verifying an authorized user operably connected to said means for blocking access to said safety latch, whereby said means for blocking access to said safety latch moves from said first blocked position to said second unblocked position upon verification of an authorized user and returns to said first blocked position upon absence of verification of an authorized user;
• and
• said means for verifying an authorized user including a voice recording and comparison circuit structured to record a voice sample from a source and compare said voice sample with at least one stored authorized voice sample to determine whether said source is authorized to fire said gun;
• wherein said means for blocking access to said safety latch comprises a stored energy circuit electrically interconnected to said means for verifying an authorized user, a generally horizontally disposed strip having a first end constructed of a first metal and a second end constructed of a second dissimilar metal electrically interconnected to said stored energy circuit, and a substantially flat blocking member seated above said strip, said strip and said blocking member being structured and disposed so that in the absence of verification of an authorized user by said means for verifying an authorized user, said blocking member covers said safety latch and upon verification of an authorized user by said means for verifying an authorized user, said stored energy circuit releases its stored energy causing said first and second ends of said strip to expand at different rates, said strip to bend away from its horizontal position and said blocking member to fall away from said safety latch, thereby making said safety latch accessible to said authorized user.
