Secure smartphone-operated gun trigger lock

A firearm system for preventing a gun from firing under certain circumstances, said system comprising, in combination:

• (a) a gun lock device, configured to be attached to or built into a gun, having a first source of electrical power and comprising the following components coupled to said first source of power:
• (1) a gun lock mechanism, responsive to a gun command signal, for preventing firing of the gun when in a locked state and enabling firing of the gun when in an unlocked state;
• (2) a first wireless transmitting and receiving (“first T/R”) device transmitting and receiving a gun information signals to and from a second wireless transmitting and receiving (“second T/R”) device;
• (3) a tamper detecting device for detecting when an attempt is made to interfere with the proper operation of the gun lock device and for providing a tamper alert when such interference is detected;
• (4) a first digital logic device, coupled to said gun lock mechanism, said first T/R device and to said tamper detecting device for (i) receiving a first gun information signal from said T/R device and producing said gun command signal in response thereto to set said gun lock mechanism in either said locked state or said unlocked state, and (ii) generating a second gun information signal for transmission by said T/R device in response to said tamper alert;
• and
• (b) a portable smartphone having a second source of electrical power and comprising the following components coupled to said second source of power:
• (1)a second wireless transmitting (“second T/R”) device for transmitting said gun information signals to, and receiving said gun information signal from, said first T/R device;
• (2) a third wireless transmitting and receiving (“third T/R”) device for transmitting and receiving data and voice signals over the public telephone network;
• and
• (3) a second digital logic device, coupled to said second T/R device and to said third T/R device, for (i) producing first gun information signals representing gun lock instructions for transmission by said second T/R device to said first T/R device, and (ii) generating a tamper alert signal for transmission to a central station by said third T/R device in response to second gun information signals;
• wherein said smartphone further includes a phone app operative to control said second digital logic device to cause said second logic device to produce said tamper alert signal, for transmission by said third T/R device to said central station, to alert the central station when the tamper detecting device determines that the gun lock device has been compromised.
