A sensor system for detecting jarring, acceleration or other application of force to a firearm, and/or movement of the firearm into an undesired orientation, which includes a sensor array mounted to a firearm. The sensor array detects the excessive acceleration and/or movement of the firearm into certain orientations and generates a sensor signal indicative of a fault condition. In response, a control system blocks or interrupts the firing sequence of the firearm to prevent inadvertent discharge of a round of ammunition by the firearm.

1. A sensor array for a firearm, comprising:a sensor array mounted to the firearm for sensing at least one of an application of a force to the firearm, an acceleration of the firearm or the firearm being moved into an undesired orientation, and generating a sensor signal indicating a fault condition
1. A sensor array for a firearm, comprising:a sensor array mounted to the firearm for sensing at least one of an application of a force to the firearm, an acceleration of the firearm or the firearm being moved into an undesired orientation, and generating a sensor signal indicating a fault condition; anda control system including a fire control and a control processor for receiving said sensor signal from said sensor array and stopping a firing sequence of the firearm sequence of the firearm upon detection of the fault condition; whereinsaid fire control includes a firing pin, a firing pin spring engaging and urging said firing pin toward engagement with a round of ammunition to fire the round of ammunition, and a solenoid for holding said firing pin in a ready to fire position, said firing pin is biased into contact with the round of ammunition by said firing pin spring to cause the firing of the round of ammunition. 2. A method of controlling firing of a round of ammunition, by a firearm, comprising:providing a sensor array mounted along the firearm;activating a firing sequence for the firearm to fire the round of ammunition;sensing a fault condition with the sensor array, including an application of force to the firearm, acceleration of the firearm or orientation of the firearm, and generating a sensor signal in response;comparing the sensor signal to a threshold reference signal and blocking the firing sequence for firing the round of ammunition if the sensor signal falls outside the threshold reference signal; andif the firing sequence is allowed to proceed, firing the round of ammunition. 3. The method of claim 2 and wherein providing a sensor array comprises positioning at least one magnetometer, accelerometer, inertia switch, acceleration switch, inclinometer, tilt switch, gyro, or strain gauge along the firearm. 4. The method of claim 2 and wherein sensing an application of force to the firearm comprises sensing a jarring of the firearm with the sensor array including at least one accelerometer, inertia switch, acceleration switch or strain gauge. 5. The method of claim 2 and wherein sensing orientation of the firearm comprises measuring an angle of inclination of the firearm with respect to a predetermined axis. 6. The method of claim 2 and wherein sensing the orientation of the firearm comprises measuring an angle of rotation of the firearm about a predetermined axis. 7. A firearm comprising:a sensor system mounted to the firearm for sensing undersirable acceleration, jarring, re-orientation of the firearm to unsafe condition, or an unsafe rate of change in orientation of the firearm, said sensor system including at least one orientation sensor adapted to sense a single axis of angular orientation of the firearm relative to the earth and generate a sensor signal related to the orientation of the firearm in relation to the earth, indicating a fault condition; anda control system receiving said sensor signal from said sensor system and stopping a firing sequence of the firearm upon detection of said fault condition. 8. The firearm of claim 7 wherein said sensor system comprises one or more electrolytic tilt sensors. 9. The firearm of claim 7 wherein said sensor system comprises one or more tilt or tip-over switches. 10. The firearm of claim 7 wherein said sensor system senses two orthogonal axes of angular orientation. 11. A firearm, comprising:a sensor system including at least one electrolytic tilt sensor mounted to the firearm for sensing undesirable acceleration, jarring, and/or re-orientation of the firearm, and generating a sensor signal indicating a fault condition; anda control system receiving said sensor signal from said sensor system and stopping a firing sequence of the firearm upon detection of said fault condition. 12. A firearm, comprising:a sensor system including a three-axis accelerometer mounted to the firearm for sinsing undesirable acceleration, jarring, and/or re-orientation of the firearm, and generating a sensor signal indication a fault condition; anda control system receiving said sensor signal from said sensor system and stopping a firing sequence of the firearm upon detection of said fault condition. 13. The firearm of claim 12 wherein said accelerometer senses two axes of angular orientation. 14. A firearm, comprising:a sensor system including a three-axis magnetometer mounted to the firearm for sensing undesirable acceleration, jarring, and/or re-orientation of the firearm, and generation a sensor signal indicating a fault condition; anda control system receiving said sensor signal from said sensor system and stopping a firing sequence of the firearm upon detection of said fault condition. 15. A firearm, comprising:a sensor system including a three-axis magnetometer and a three-axis accelerometer mounted to the firearm for sensing undesirable acceleration, jarring, and/or re-orientation of the firearm, and generating a sensor signal indicating a fault condition; anda control system receiving said sensor signal from said sensor system and stopping a firing sequence of the firearm upon detection of said fault condition. 16. A method of controlling firing of a round of ammunition by a firearm, comprising:providing a sensor system mounted along the firearm;activating a firing sequence for the firearm to fire the round of ammunition;sensing a fault condition with the sensor system, including an application of force to the firearm, acceleration of the firearm and/or orientation of the firearm and generating a sensor signal in response;comparing the sensor signal to a threshold signal and blocking the firing sequence for firing the round of ammunition if the sensor signal falls outside the threshold; andif the firing sequence is allowed to proceed, firing the round of ammunition. 17. The method of claim 16 and wherein providing a sensor system comprises positioning at least one magnetometer, accelerometer, inertia switch, acceleration switch, inclinometer, tilt switch, gyro, or strain gauge along the firearm. 18. The method of claim 16 and wherein sensing an application of force to the firearm comprises sensing a jarring of the firearm with the sensor system including at least one accelerometer, inertia switch, acceleration switch, shock sensor or strain gauge. 19. The method of claim 16 and wherein sensing orientation of the firearm comprises measuring an angle of inclination of the firearm with respect to a predetermined axis. 20. The method of claim 19 and further including measuring an angle of rotation of the firearm about a second predetermined axis.
